Salmon feed commonly includes fishmeal and fish oil, which are essential for providing protein and omega-3 fatty acids, alongside plant-based alternatives like soybean meal and wheat flour to enhance sustainability and reduce reliance on marine resources.

Probiotics, such as lactic acid bacteria, are increasingly incorporated into salmon feed to boost fish immunity and growth, thereby reducing the risk of disease outbreaks caused by environmental stressors like high temperatures.

Minerals, vitamins, and amino acids are added to salmon feed to optimize nutrient absorption, support immune function, and improve overall fish health and productivity.

Uncommon additives like glucan, derived from probiotics such as Lactic Acid Bacillus B4, are used to enhance fish growth and immunity, particularly in aquaculture environments prone to high temperatures and pathogens.

Another rare additive, Polydeoxyribonucleotide (PDRN), derived from salmon sperm DNA, has potential applications in aquaculture for regenerative purposes, although it is more commonly used in cosmetics.

Seaweed, such as Haimen winter, is being explored as a feed additive to improve environmental sustainability and nutrient cycling, with potential applications in aquaculture similar to its use in reducing methane emissions in livestock.

Synthetic pigments like astaxanthin are added to farmed salmon feed to mimic the natural carotenoids found in wild salmon, giving the fish a bright orange-red color that appeals to consumers.

While astaxanthin is generally considered safe for human consumption, the high fat content in farmed salmon, often a result of feed additives designed to accelerate growth, can lead to the accumulation of fat-soluble pollutants, raising potential health concerns.

Antibiotics are frequently used in salmon feed to prevent diseases in high-density farming environments, but their use has been criticized for contributing to antibiotic resistance and contaminating surrounding ecosystems.

Alternatives to antibiotics, such as bacteriophage technology, are being developed to control pathogenic bacteria in aquaculture, offering a safer and more sustainable solution to reduce antimicrobial resistance and environmental impact.

Growth hormones are sometimes added to salmon feed to stimulate faster growth and increase production efficiency, but concerns have been raised about potential residues in the final product, which may pose health risks such as cancer to consumers.

Insect-based proteins, derived from black soldier fly larvae, are emerging as a sustainable alternative in salmon feed, offering an eco-friendly option that avoids the use of wild fish or soy, though their long-term health impacts on consumers remain under study.

Preservatives are used in salmon feed to extend shelf life and inhibit bacterial growth, ensuring the feed remains safe and effective for consumption by farmed salmon.

Benzoic acid, a commonly used preservative, can cause gastrointestinal discomfort, nausea, and vomiting if consumed in excessive amounts, raising concerns about its potential health risks when residues accumulate in farmed salmon.

Additives like vegetable oils, soy proteins, wheat gluten, and corn gluten meal are often used in salmon feed to reduce reliance on feed-grade fish, which can harm ocean ecosystems by disrupting food chains and biodiversity.

Some farmed salmon have been found to contain elevated levels of polychlorinated biphenyls (PCBs), which are environmental contaminants linked to cancer risks, raising concerns about the indirect health impacts of feed additives and farming practices.

In certain cases, harmful practices such as feeding fish with untreated waste from chicken slaughterhouses have been reported, leading to bacterial contamination and increasing the risk of chronic or carcinogenic diseases in humans consuming these fish.

Norway enforces stringent regulations on salmon feed additives, focusing on sustainability and minimizing environmental impact, and is researching alternatives like mesopelagic fish, algae, and farmed insects to reduce reliance on fishmeal and fish oil.

Chile maintains strict oversight of feed additives through its aquaculture regulations, ensuring compliance with international standards to protect both farmed salmon health and surrounding ecosystems.

Canada regulates salmon feed additives under its aquaculture guidelines, emphasizing the use of approved substances and monitoring for contaminants to ensure consumer safety and environmental sustainability.

International standards for salmon feed additives emphasize sustainability, with countries like Norway exploring innovative alternatives to reduce reliance on fishmeal and fish oil, which are essential but limited resources globally.

Local regulations in major salmon-producing countries, such as Canada, require salmon farms to have management plans for issues like sea lice and pesticide use, with strict limits on residues and public reporting of compliance.

Labeling requirements for farmed salmon products often mandate the disclosure of feed additives, especially if they include substances that could pose health risks, such as banned drugs or preservatives like sulfur dioxide.

Consumers can identify farmed salmon products with minimal harmful additives by prioritizing those with production traceability marks, QR codes, or certifications such as CAS, which ensure transparency and safety in sourcing.

Authorities like the Taipei City Health Bureau emphasize the importance of vendors obtaining independent inspection reports to ensure farmed salmon products are free from harmful residues such as leucocrystal violet, a carcinogenic substance.

Recent studies have raised concerns about the use of certain additives in farmed salmon feed, such as PCBs, which have been found at concentrations up to eight times higher in farmed salmon compared to wild salmon, potentially increasing cancer risks.

Organic and sustainable salmon farming practices often avoid harmful substances like antibiotics and carcinogenic formaldehyde, which are commonly used in conventional farming to prevent disease outbreaks.

Sustainable salmon farming may incorporate probiotics into feed to improve water quality and fish health, contrasting with conventional methods that rely heavily on fishmeal and fish oil derived from wild-caught fish.

Integrated multi-trophic aquaculture systems use complementary species like mussels and seaweed to naturally recycle nutrients, reducing the need for chemical additives in salmon feed and promoting environmental balance.

Omega-3 enhancing additives in salmon feed, such as fish oil and vegetable oil, significantly influence the nutritional profile of farmed salmon by increasing levels of EPA and DHA, which are beneficial for heart health and cognitive function.

Farmed salmon often contains higher levels of omega-3 compared to wild salmon due to the controlled inclusion of fish oil in their feed, but the use of vegetable oils as a cheaper alternative can reduce omega-3 levels.

Health risks associated with omega-3 enhancing additives in salmon feed include potential contamination with heavy metals or pollutants in fish oil, emphasizing the need for regulatory oversight and quality assurance.

Probiotics such as lactic acid bacteria B4 are added to salmon feed to improve growth rates and enhance immunity, which can reduce the risk of disease and shorten farming time while promoting gut health when consumed indirectly through fish products.

Mineral-based feed additives like Calibrin-Z and Varium are used to bind toxins and pathogens, strengthen intestinal barriers, and improve fish health, though their long-term effects on human health require further research.

Bacillus subtilis-based microbial preparations in aquaculture feed enhance growth efficiency and immunity in fish while reducing environmental impacts, and these additives are generally safe for human consumption.

Emerging technologies in salmon farming, such as integrated multi-trophic aquaculture, aim to reduce reliance on harmful additives by farming complementary species like mussels and seaweed alongside salmon.

Insect-based feed ingredients, such as those produced by Ÿnsect, are being explored as sustainable alternatives to traditional fishmeal, offering benefits like faster fish growth and reduced feed consumption.

Norway is researching innovative feed solutions, including mesopelagic fish, algae, and farmed insects, to reduce reliance on fishmeal and fish oil, with the goal of creating entirely vegetarian feeds for certain species.

Salmon feed commonly includes fishmeal and fish oil, which are essential for providing protein and omega-3 fatty acids, alongside plant-based alternatives like soybean meal and wheat flour to enhance sustainability and reduce reliance on marine resources.

China Works to Get Wild-Caught Fish Out of its Aquaculture Feed

[By Zhang Chun]

A 2021 Chinese government initiative to stop aquaculture feed being made from only young or low-value fish and to instead start producing “compound feed” – mixed with ingredients harvested from the land – is opening up a greener future for the sector.

According to the Ministry of Agriculture, in a series of trials last year, the sole use of low-value “feed-grade” fish as aquaculture feed was reduced by 77 percent, and by as much as 94 percent in farming of largemouth bass. Experts say the switch to compound feed could see overall use of feed-grade fish slashed by half for farming of certain species.

What is compound feed?

Compound feed normally contains a mixture of animal- and plant-based ingredients, and added nutrients such as vitamins. For aquaculture feeds containing fishmeal and fish oil, common additives include soy proteins, wheat gluten and corn gluten meal.

Feed-grade fish are those in a catch that are small, low in commercial value, or unsuitable for human consumption. They are sent to be processed into fishmeal and fish oil, or fed directly to farmed fish. But a significant proportion of feed-grade fish consists of juveniles of commercially important species. Once caught they can no longer grow into adult fish and breed, or be caught and sold on the market. Their removal damages ocean food chains and ecosystem stability.

The last decade and more has seen increased calls for China to tackle the use of feed-grade fish in aquaculture, but the current round of trials is the first organised by the Ministry of Agriculture. It focuses on species such as the yellow croaker, Japanese sea bass and largemouth bass, which tend to be fed more feed-grade fish. While those species don’t account for much of China’s fed aquaculture output, they do require much more protein than others to put on the same amount of weight. Compound feed cuts down on the use of fish by substituting vegetable alternatives, and is cheaper.

In the long term, sustained reductions in the use of fishmeal and fish oil in feed will be necessary to protect wild fisheries.

Aquaculture driving feed-grade fish catch

Fishers never used to set out to catch feed-grade fish; it was bycatch, with no economic value. Then in the 1980s, global aquaculture took off. “There was a lot of need for fishmeal and oil,” Rashid Sumalia, a fisheries researcher at the University of British Columbia, told China Dialogue. People started going out “purposely to catch them at distance, because there was a market”, he added.

According to the Food and Agriculture Organization’s (FAO’s) 2020 global fisheries and aquaculture report, the use of fish for reduction to fishmeal and fish oil peaked in 1994 at 30 million tonnes, and stood at 18 million tonnes by 2018. Another 4 million tonnes were used elsewhere, including directly in feed for aquaculture, livestock and fur animals.

It wasn’t until the mid and late 1990s that aquaculture took off in China. The FAO’s 1998 fisheries and aquaculture report describes how rare it was for fish catches in Asia to go unused or be used as aquaculture feed. But in Asia, particularly in China and Vietnam, aquaculture has expanded rapidly and the region now accounts for almost 90 percent of global output. In China, output tripled between 1998 and 2020, to represent 60 percent of the global total.

Although many of the species farmed in China need little or no feed, fed fish and crustacean aquaculture accounts for half of output and requires millions of tonnes of feed-grade fish from Chinese waters alone. China does not currently have statistics on its feed-grade fish catch or use in fed aquaculture. One study calculated that in 2016 4.6 million tonnes of feed-grade fish were caught, 35 percent of the total recorded catch in China’s waters, and most was used directly as feed.

“The state is certainly aware of the problem,” said Fang Qing, China general manager for the Aquaculture Stewardship Council, adding that the difficulty in banning some harmful types of fishing gear in China is due to the ongoing market for the feed-grade fish it brings in. Since 2018, China has put minimum size limits in place for 15 commercial fish species, and ruled that feed-grade fish catch would drop to below 20% by 2020. There is no data available indicating whether this target was met.

This it isn’t just a Chinese problem. According to a 2017 study by the University of British Columbia, many countries, including the US and Norway, use feed-grade fish directly as feed. But the practice increased significantly in Asia between the 1990s and 2010, with feed-grade fish coming to account for a high percentage of landed catches.

Replacing feed-grade fish

In early 2019, the Ministry of Agriculture announced it would work to make Chinese aquaculture more environmentally friendly, and proposed the use of compound feed instead of purely fish-based feed. In April 2021, several provinces started trials of compound feed as part of more concrete action plans.

Compound feed for aquaculture is usually a mix of fishmeal, fish oil, wheat flour, soybean meal, vegetable oil and other land-grown ingredients. The amount of fishmeal and fish oil needed depends on the type of fish to be fed, and its stage of growth. According to Fang Qing, carnivorous fish such as the yellow croaker need huge quantities of meat protein at certain stages in their growth, and the relationship between particular nutrients and the growth and physiology of the fish can be complex. Hence, producing appropriate compound feed involves a lot of research and development.

To quantify how efficiently a species is farmed, the aquaculture industry uses a ratio called Fish in:Fish out (FIFO). The closer the FIFO is to 1, the more fish meat is produced per unit of input; a score of 1 means an extra kilogram of fish used as feed results in an extra kilogram of fish to harvest.

A study published in 2020 shows a FIFO of almost 1 for salmon and trout, thanks to the use of compound feeds which require less fishmeal and fish oil. If only fish were used to feed those species, the FIFO figure would be similar to that of the yellow croaker – over 6, according to an upcoming paper co-authored by Zhang Wenbo, an assistant professor in the College of Fisheries and Life Science at Shanghai Ocean University. His research into conventional yellow croaker aquaculture in China found that the direct use of feed-grade fish is still the best option for the yellow croaker farmers. But Fang Qing told China Dialogue that a lot of feed-grade fish fed to yellow croaker goes uneaten, and ends up sinking to the seabed or rotting, causing pollution and increasing the risk of disease.

More compound feed use would help reduce FIFO numbers in two ways: by cutting use of feed-grade fish, and by increasing conversion ratios – that is, generating more fish growth per unit of feed.

Zhejiang is taking the lead in both those areas. Since 2016, the province has been shutting fishmeal factories during the closed season and restricting the percentage of feed-grade fish in the overall catch. This, combined with the use of compound feed, saw Zhejiang cut the use of feed-grade fish by 835,000 tonnes across 710,000 mu (474 square kilometres) of aquaculture farms during the 13th FYP period (2016-2020). “Previously, feed-grade fish were the primary feed for largemouth bass in Zhejiang. These last two years that’s almost all been replaced with compound feed.” The FIFO ratio for farmed largemouth bass in Zhejiang could come down to 1.5, half the national average for this species, according to 2016 calculations Zhang Wenbo contributed to.

But cutting back on feed-grade fish use in China won’t be easy. Fishers catch a wide range of fish with a wide range of gear. At the local level there is a lack of fisher associations that can impose rules on the sector, making management tricky. Zhejiang’s success can be ascribed to strong local regulations. “There are no successful [international] examples that China can apply,” said Fang Qing. Alongside legislation to bolster oversight of the feed-grade fish catch, he also suggests developing feeds which will be more palatable to fish, and labelling products according to their use of feed-grade fish or compound feed, so consumers can make an informed choice.

Increasing the efficiency of fish inputs

The use of compound feed isn’t the end of the story. At least for now, fishmeal and fish oil are essential ingredients in those feeds. And while the global supply of fishmeal and fish oil has fallen from its peak in 2000 to a fairly stable level, the demand for aquaculture feeds has been increasing. That requires the development of feeds containing less meal and oil.

Plans announced by Norway to boost salmon farming have led to concerns about the supply of fishmeal and fish oil as well as vegetable ingredients. The country has started researching the use of mesopelagic fish (which inhabit the middle depths of the ocean), algae and farmed insects to meet that need and make feed more efficient. A more complete solution would be to develop entirely vegetarian feeds, with no fishmeal at all. However, as things stand that would only be suitable for a few species.

“Fishmeal is the most expensive of the ingredients found in bulk feeds. Reducing the amount in those feeds is the best way to make them cheaper,” Zhang Wenbo points out. A tonne of fishmeal costs around 10,000 yuan (US$1,500), compared to 1,000–4,000 yuan for bran or soybean meal, he added. “Feed conversion ratios are also affected by the type of aquaculture, the make-up of the feed, and genetic selection – the breeding of strains more suited to compound feeds,” he said. This is more difficult in China, with its wide range of farmed species, than in Norway, where salmon dominates. But progress is still being made, and associated targets have been set in the 14th Five Year Plan (2021–25).

Increasing the efficiency of fishmeal and fish oil use in China will also ease global pressures on the supply and help protect juvenile fish. China is the world’s biggest consumer of fishmeal, with the largest part being used in aquaculture, and the second largest being fed to pigs. But the country only produces 400,000–700,000 tonnes of fishmeal a year – not even close to meeting domestic demand. Fishmeal imports have held steady since 2017, at about 1.4 million tonnes, but jumped to 1.82 million tonnes in 2021, with experts ascribing the change to the recovery in pig farming. The extra fishmeal came from the Americas and elsewhere in Asia.

Zhang Wenbo explains that China’s fishmeal and fish oil imports come from forage fish, caught specifically to be turned into fishmeal, and Peru is the main supplier. Relatively little of China’s fishmeal is made from feed-grade fish. “Imports of by-product processed fishmeal from Vietnam and Thailand have been increasing in recent years,” he said.

Minimizing the feed-grade fish catch

Cutting back on the use of feed-grade fish is good for the sustainable development of both wild fishing and aquaculture. It will also help protect already vulnerable ocean ecosystems. In 1959, fishing vessels in China’s Bohai Sea caught 420 kg of fish per net for every hour they worked. By 1993, that had fallen to 30 kg, and only 8 kg between 1998 and 2011. The above-mentioned research into China’s feed-grade fish catch found that a long-term stable total catch has masked trends including falling biomass and changes in end use.

The losses to biodiversity and ecological services cannot be measured in financial terms, and the fishing industry needs more than simply output. Wang Songlin, president and founder of the Qingdao Marine Conservation Society, believes the industry needs to work towards a balance of ecological, economic and social benefits. He told China Dialogue that even if total catch may still be the same by volume, the underlying destruction to the integrity of ecosystems and the environment should not be ignored.

Management of the sector in China has acquired a new ecological focus. Alongside the use of compound feeds, some provinces are providing fishery stewardship subsidies for the protection of rare and endangered species and for keeping down feed-grade fish catch volumes.

Protecting juvenile fish isn’t just a matter for China – it’s crucial for ocean ecosystems around the world. Rashid Sumalia said: “If you look at the economies and the ecology at the higher level, you don’t want to [catch feed-grade fish] because the losses are too high” to be sustainable. Sumalia acknowledges that many people rely on that fishing for their livelihoods but says: “We need to take it down as far as we can.”

In recent years, the unusually high temperature in summer has led to the outbreak of germs, which has caused great losses to farmers. The probiotic Lactic Acid Bacillus B4, which helps to improve fish growth and enhance their immunity, and its glucan product Lactic Acid Bacillus B4 functional yogurt was added to the feed. Farming time to reduce the risk of breeding.
The water laboratory pointed out that glucan can be used as an emulsifier and thickener flavor carrier in food processing. In terms of health care, research shows that glucan can be used as a prebiotic to increase the number of probiotics - bifidobacteria and lactic acid bacteria in the body, and regulate immunity.
As mentioned in the water test, lactic acid bacteria B4, previously screened from the gut of perch fish, is a probiotic with special enzymes. Adding cheap sucrose can promote the production of glucan by lactic acid bacteria B4, and developed functional yogurt and ice cream containing glucan with lactic acid bacteria B4.

According to the water test, the literature points out that probiotics or prebiotics such as glycans and oligosaccharides as feed additives can effectively improve the growth and immunity of fish and shrimp. The combined use of probiotics and prebiotics is usually higher than the combined effect of the two alone. Probiotics that produce pathogens can also produce glucans themselves, so the lactobacillus B4 yogurt is applied to aquaculture.
Experimental studies show that the addition of lactic acid bacteria B4 yogurt in the feed helps to improve the growth and resistance to pathogens.

In recent years, due to climate change, the unusually high temperature in summer can easily lead to the outbreak of germs, causing the death of fish and loss of farmers. Three years ago, the Kaohsiung City Animal Protection Department sought technical assistance from the water laboratory. 4 Yogurt feed for 2 months, fish feeding conditions are better than the control pond, growth is very fast, at the end of May harvest, no disease, fish average weight 570 grams, strong and healthy.
When the fish are harvested, the fisherman must wear a safety helmet to avoid being injured by the energetic Wu Kuo. The fish in the control pond eat worse than the test pond and grow more slowly. In mid-June, the fish suffered from streptococcus disease. It must be treated with drugs. The average weight is 467 grams, which is much lower than the average. Test pool.
The water laboratory further stressed that in order to understand whether the feed containing lactic acid bacteria B4 yogurt can really survive the cool summer, and the Kaohsiung Municipal Bureau of Animal Protection specially arranged the test in the summer the previous year. The results showed that although the test group and the control group of the fish containing lactic acid bacteria B4 yogurt were all suffering from streptococcal disease, the test group were milder drug. The treatment only takes 3 days to heal, and the control group is more serious, requiring more than 7 days of drug treatment.
Therefore, the addition of lactic acid bacteria B4 yogurt in broccoli feed helps to improve the growth and health of the fish, shortens the breeding time, reduces the breeding risk and slows the severity of the disease, and the cost of adding lactic acid bacteria B4 yogurt per kilogram of feed is only about 0.5 yuan.

Agriculture: Poultry production depends on 55% of small breeders.
The sector recovered soon.
A report by the Ministry of Agriculture and Land Reclamation revealed the recovery of the poultry industry during the coming period from the repercussions in which the industry was exposed during the recent period after the adoption of poultry production on 55% of small breeders.
A report by the Ministry of Agriculture and Land Reclamation, represented by the Animal Production Research Institute, said that the decline experienced by the poultry industry and production will be recovered from its consequences at the earliest opportunity, in light of the tangible boom achieved by the small breeder, which cost us to achieve self-sufficiency during the past years.
The report downplayed the repercussions of the recent crisis in the poultry production sector, explaining that large entities are the most affected, while the basic strength of the industry, represented by small breeders, has remained largely stable.
The report pointed out that the basic strength of poultry production projects depends mainly on the segment of small breeders, which represents about 55% of the actual strength of this economic activity, where he touched on the file of feed additives, explaining its importance to the poultry production industry, which is mainly based on maximizing the benefit of all inputs.
The report stressed that the desired goal of the use of feed additives, is to achieve the maximum possible absorption rate of protein, carbohydrates and fats, from the feed formula provided to birds, in a way that enhances the doubling of their productivity and improve their properties.
Feed additives are divided into two main sections: Feed additives: are those additives that enter the food directly, most notably vitamins of both types “fat ” and“ soluble in water ”, and play an active role in the completion of the process of digestion, in addition to its strong contribution to improving immunity.
The report added that the breeder aims to maximize productivity and double immunity rates, which achieves a tangible economic savings for the breeder, and is reflected positively on the level of profitability expected by the end of each cycle, explaining that amino acids “amino acid ”: the cell building unit and the pillar of animal protein production, in addition to its important role in the formation of immune bodies.
The report added that the mineral salts: divided into two basic “structural salts ”, the most important of which are“ calcium, potassium, magnesium ”, which enter as the main part in the synthesis of bones, and “non-food salts ”, and play the role of regulator of metabolic processes that take place within the body.
The report pointed out that there are non-food feed additives: the latest trend in the world of feed additives, which specialists call “yeasts ” or“ plastics, ” and represent a type of bacteria beneficial to living organisms.
The report stressed that the latest scientific research revealed that each gram of intestinal juice of a healthy human or animal, contains "1210" bacterial organism, as one of the most prominent manifestations of health, while some studies have found that 30% of the weight of the organism is only bacteria.

Uncommon additives like glucan, derived from probiotics such as Lactic Acid Bacillus B4, are used to enhance fish growth and immunity, particularly in aquaculture environments prone to high temperatures and pathogens.

Another rare additive, Polydeoxyribonucleotide (PDRN), derived from salmon sperm DNA, has potential applications in aquaculture for regenerative purposes, although it is more commonly used in cosmetics.

Content: What Is A Salmon Sperm Facial? The Dark Side To The Beauty Trend

People are having DNA derived from salmon sperm injected into their faces to make them look younger

By

5 Minutes Read

Salmon sperm facials made the news last year after Jennifer Aniston told the Wall Street Journal she had tried one. Now the anti-ageing treatment is tipped to become a big beauty trend of 2024.

Injecting sperm into your face sounds gross – though it isn’t actually sperm that’s used. But the bigger problem is the industry behind the trend: salmon farming and fishing.

Here we delve into the dark side of the salmon sperm facial and the problem with using animal products in cosmetics.

What is a salmon sperm facial?

The “sperm” in the facials is actually DNA derived from the sperm of salmon. It’s technical name is Polydeoxyribonucleotide, or PDRN, which is how the ingredient may be labelled on cosmetics products. PDRN refers to several bioactive molecules derived from purified and sterilized DNA taken from salmon sperm.

A treatment involves having PDRN injected into your face using a small needle. It is supposed to stimulate collagen production and help cell renewal. Several sessions are recommended across several months to see results. PDRN is also found in some luxury skincare products like lotions and supplements. The fad originated in South Korea, the home of skincare regimes that have become a global phenomenon known as K-beauty.

There is some research showing that PDRN can help wounds to heal, discovered through animal experimentation. But there have been few human trials to test it’s efficacy for cosmetic or medical purposes.

Where does the sperm come from?

According to Metro, the salmon-derived ingredient in the treatment is a by-product of seafood production. “[R]ather than it being tossed away when wild Alaskan salmon is prepared, instead the beauty industry snaps it up.”

It’s not clear whether the PDRN used by beauty companies comes exclusively from wild Alaskan salmon, or whether some is obtained from farmed salmon. Either way, both industries are deeply problematic, and the use of their by-products by the beauty industry is not as harmless as it sounds.

Taking fishes from the wild

Populations of wild Atlantic Salmon are declining globally, with some communities in crisis. For example, in UK rivers – a breeding ground for the species – populations hit a record low in 2022.

This is despite efforts to conserve Atlantic salmon numbers through fishing exclusion zones being established since the 1980s. The global decline is likely due to illegal and unregulated fishing activity, according to one study. Dammed rivers, warming waters due to the climate crisis, and sea lice proliferating at salmon farms attaching to wild fishes may also impacting the health of wild salmon populations.

Salmon farming

Farming salmon is supposed to help alleviate pressure on wild populations. Most of the salmon sold in supermarkets in the UK come from Scottish farms. Indeed, globally more fishes killed for food now come from farms than from the wild. This makes it seem more likely that the PDRN in cosmetics is currently, or will in future be, derived from farmed salmon (though we don’t know its origins for sure).

Salmon farming has many negative impacts on the fishes and the marine environment. Undercover investigations have shown how farmed salmon suffer from predation, sea lice infestations, and disease outbreaks. Mortality rates on farms have also been rising due to warming waters – a problem only set to get worse in future.

The sea lice infestations on farms are bleeding into wild salmon who swim past the pens of their captive kin. In Scotland, there are plans to establish protection zones for wild salmon to keep them safe from the sea lice outbreaks on farms.

Pollution including waste and pesticides from farms has been rising and wreaking havoc on surrounding ecosystems.

By-products aren’t harmless

Using by-products from the meat, fishing, and farmed fish industries – known as rendering – does not simply reduce waste from those industries. It financially supports them by adding value to their products.

Slaughtering animals for food produces a lot of waste, such as blood, bones, skin or scales, hoofs, intestines, and fish swim bladders. Treating and disposing of it in an environmentally safe way is expensive, which is why animal industries would rather sell it. Development in technology are increasingly enabling them to extract materials from waste and monetize it.

The value that rendering adds to animal industries can lead to the products derived from waste becoming a driver of destructive practices.

For example, bovine collagen, used like PDNR as an anti-ageing treatment, has become extremely popular. In 2023, an investigation by several news organizations uncovered links between collagen supply chains and Amazon deforestation. The booming collagen industry means that, along with leather, collagen makes up an increasing portion of the profit made from cows raised in the Amazon who are killed for beef.

Marine collagen, derived from the skin of fishes, is also becoming popular. It could potentially provide a new revenue stream for seafood companies. Collagen, salmon sperm, and other fish waste products that can be rendered could thus become more of a reason in themselves for slaughtering fishes.

As global climate change intensifies, greenhouse gases such as carbon dioxide and methane are considered to be the main cause of disasters, and livestock is the main source of methane emissions.
Recently, research has pointed out that adding Haimen winter to cattle and sheep feed can greatly reduce the methane emissions of cattle and sheep. The Donggang Biotechnology Research Center of the Fisheries Research Institute of the Council of Agriculture has invested in the artificial culture technology of "carbon reducing algae" Haimen winter to make a contribution to "net zero emissions".
In recent years, the frequency and intensity of extreme weather such as warm winters, heat, prolonged droughts and heavy rains have increased, and greenhouse gases such as carbon dioxide and methane are considered to be the main cause of disasters.

According to a recent study, adding 1% of dry sea gates to cattle and sheep feed can greatly reduce the methane emissions generated by the fermentation of their intestines. But the number of cattle raised worldwide is about 1 billion, and the amount of seaweed needed to be added is definitely not available for field harvesting. Business opportunity.

In order to reduce carbon emissions, the Tungkang Center of the Water Research Institute has been actively involved in research on Haimen winter for the past two years. Preliminary investigations have found that the wild distribution of Haimen winter in Taiwan is quite sporadic, and that it can be found in northeastern China, Penghu, Hsiao Liuchiu and Hengchun Peninsula.
The institute says it will actively conduct experiments on artificial breeding, and will design suitable aquaculture tanks according to the natural environment, hoping to establish an artificial mass production model for Haimen winter as soon as possible, and through the diffusion of technology, assist operators to invest in aquaculture, and build a seaweed industry chain.

There are three major differences between wild salmon and farmed salmon.
The average consumer relies on the label on the packaging to confirm whether the salmon is farmed or wild, and the food label is different from country to country.
Stan liked the Japanese way of labelling the fish. Whether it was farmed or wild was clearly written; however, if there were no such labelling elsewhere, how would you know where it came from?
In order to make the meat more beautiful, the fish will be added to the feed to make the meat appear bright orange red, attracting consumers to buy, that is, everyone sees the color of salmon meat on weekdays, because the wild salmon does not have that kind of pigment, the fish will appear dark red, it does not look so beautiful.
If you look carefully, the fish meat of the salmon will have a very obvious white fat line, because the feed is specially added a lot of fat to speed up the weight of the fish, but in fact, the wild salmon in the food eaten in the wild environment, there is not so much fat, so the fat line of the wild salmon is smaller than that of the fish.
In addition, because many pollutants are fat-soluble, too much fat in fish makes pollutants accumulate; in terms of taste, wild salmon does not have as much fat as fish, so it is not so oily when cooking, but its fish meat is more delicious.
Of course, you may be very health-conscious and afraid that wild salmon is too expensive, but there are many other omega-3 rich ingredients to choose from.
Fish, you can eat mackerel, mackerel, tuna, sardines, etc. Plants, you can eat flaxseeds, chia seeds and peach, but note that the Omege-3 of the plant is not directly absorbed, you must undergo physical transformation to obtain, so absorption will be slower; as for supplements, you can choose fish oil or krill oil, these are very good and convenient to choose.

What are some of the additives that are added to salmon feeds in salmon farms?

What are the purposes of adding pigments to the feed in salmon farms?

While astaxanthin is generally considered safe for human consumption, the high fat content in farmed salmon, often a result of feed additives designed to accelerate growth, can lead to the accumulation of fat-soluble pollutants, raising potential health concerns.

Antibiotics are frequently used in salmon feed to prevent diseases in high-density farming environments, but their use has been criticized for contributing to antibiotic resistance and contaminating surrounding ecosystems.

More than 300 people change their name to eat enough … your favorite salmon is abused and pollutes the sea? Netflix "Ocean Conspiracy" exposed to the black screen
In the past, more than 300 people in Taiwan changed their name after turning around the famous sushi restaurant “Sushi Lang ” to launch the“ Free Salmon to Eat ” campaign, setting off a “salmon chaos ” in society, showing the people ’ s love for salmon.
With Netflix ’ s new ecological crisis documentary “Seaspiracy ”, which exposes the problems of antibiotics released by“ sea captive salmon ” and fears of pollution, as well as millions of salmon crammed in underwater cages, mercilessly attacked by fish lice, and violating the nature of wild migration, people can ’ t help but look at the issue of animal persecution. It has been proven to sense pain.
What are the cruelties hidden in the world-famous seafood “farmed salmon ”?
How can fish welfare be improved?
More than 300 people changed their name to "salmon" to eat! The salmon that Taiwanese love to eat is not wild at all.
As with many livestock farms on the land, salmon is of high economic value, so many aquaculture operators around the world use sea box nets to trap and breed salmon in captivity, and regularly feed them to pipelines in order to obtain huge "salmon gold" business opportunities.
If you look at Taiwan from a perspective, according to the statistics of customs imports and exports in 2020, the weight of locally imported “captive salmon ” alone is as high as 18,000 tons, with a total value of about NT $5.15 billion.
On the other hand, even if the world is hit by the epidemic in 2020, Norway, the world ’ s largest exporter of salmon, not only will the production of salmon still reach 1.1 million tons, but the export volume will also reach a record second high.
But with the release of Netflix ’ s new marine crisis documentary “Seaspiracy ” in 2023, the blood-soaked disclosure of the sea farming salmon behind the following three unknown dark sides, finally let the terrible“ salmon hell ” shake the world.
1.
High-density farmed salmon have nowhere to escape! Scales and fins are mercilessly devoured by sea lice parasites
Compared to free wild salmon, captive salmon are likely to be crowded together by the fish, constantly colliding, friction, conflict, and nowhere to hide, resulting in scales, kisses, and fins are broken, infectious anemia, spinal deformities and other symptoms, and are more likely to be parasitized by sea lice.
For example, a survey by the global animal lobby welfare organization Compassion in World Farming found that floating dead fish can be found everywhere in crowded salmon farms, and such a harsh living environment is simply a hotbed for the spread of disease.
What is even more frightening is that once the salmon is entangled in sea lice, the scales, skin tissue, surface mucus and blood on the body will soon become food for the parasites.
As the scales of the salmon gradually disappear, in addition to the pain of the body beginning to erode, the pain of infection in the wound or loss of immunity can also plunge them into the abyss of death.
For example, in the clip of "The Ocean Conspiracy", it directly captures the horror of the salmon being eaten alive by a parasite to the eyes, the limbs, and the body.
2.
Marine farmed salmon put into chemicals, antibiotics! Marine pollution affects ecological food chain
In order to solve the salmon nightmare, farmers have to put a lot of irritating chemicals and antibiotics into the box to remove sea lice and reduce the risk of disease in high-density breeding, or to increase the water temperature and try to kill sea lice.
But the pumps and containers used by the former to transport chemicals have undoubtedly made the salmon's sea cages smaller and tighter, while the temperature of the latter has already exceeded the range that the salmon can adapt to, and each of them has brought great pain to the salmon.
At the same time, antibiotics and pesticides flowing into the sea will of course lead to pollution of the surrounding environment, and the organic waste generated by captive salmon will also seriously affect the entire bottom ecology.
In April 2023, the environmental group Greenpeace accused Chile ’ s salmon farming industry of dumping sewage into the ocean, killing more than 5,000 tons of salmon from oxidation.
3.
Undersea cages violate the migratory nature of wild salmon! Millions of animals are ignored
Not only that, Scotland, the world ’ s third largest Atlantic salmon farming exporter, which supplies about 10% of Taiwan ’ s salmon imports each year, has also been raised by the farm animal protection group Compassion in World Farming (CIWF) at the end of 2020, pointing directly to the 22 farms of the local five largest salmon farming companies, and raising millions of salmon in the sea bottom in one breath, completely depriving them of their migratory nature.
Because the migratory nature of salmon has always been a mystery in the animal world, some studies have suggested that salmon can always find the "origin" by remembering the special smell of their birthplace, or by being guided by the magnetic fields of the Sun and Earth.
Regardless of the truth, the physiological structure of salmon is obviously sensitive to sensing the environment, judging the location, and even evading electric shocks in real time.
Therefore, allowing them to roam aimlessly in the box for many years is a kind of cruelty to the body and spirit, depriving the fish instinct of long-distance migration.
All the unhealthy salmon raised in captivity are eaten by humans!
Food chain security in jeopardy
In other words, the three major concerns of captive salmon at sea have caused more than 25% of Scotland ’ s fish populations to suffer and die before they are slaughtered, resulting in a huge waste of food and a complete disregard for animal welfare.
In addition, countless dead fish have been dumped directly in open barrels by Scottish farmers, allowing wild birds and other wildlife to come into contact for food, potentially endangering the safety of other ecological chains.
Salmon farming on land is more humane to the earth! Salmon business opportunities and marine conservation to create food sustainability
Fortunately, this traditional salmon farming method is expected to gradually come to an end.
Because the international company Atlantic Sapphire has been developing "land salmon farm" for 10 years, and in 2022, it invested nearly 4 billion US dollars (about 112 billion US dollars) to build the world's largest land salmon farm Bluehouse in Florida, the United States.
The biggest feature of the land salmon farm is the use of the Recirculating Aquaculture System (RAS) to effectively control the temperature, salinity, pH and oxygen content of the water body, and effectively eliminate carbon dioxide and filter waste, to ensure that the salmon are free from parasites and diseases, while reducing the possibility of marine pollution.
Johan Andreassen, CEO of Atlantic Sapphire: “Ten years ago no one believed that farming salmon on land was financially viable; now Atlantic Sapphire is finally proving that it works, so the question now is how much competition there will be and how much scale there will be in this industry. ”
In order to prove that land-based salmon farming will eventually become a trend in the marine industry, Atlantic Sapphire CEO Johan Andreassen is also looking further into the future, with an estimated 372,000 square meters of fish tanks on about 650,000 square meters of land by 2031, allowing land-based salmon to meet 41% of the annual salmon consumption in the United States.
Also thanks to Atlantic Sapphire, one of the world ’ s largest salmon producers, Norwegian company Grieg Seafood has entered into a joint venture with Årdal Aqua to build a 5,000-tonne annual land farm there.
Salmon Evolution, also from Norway, joined forces with Dongwon Industries, South Korea ’ s largest seafood company, in 2023 to expand its “salmon footprint ” to South Korea.
At the same time, Benchmark Genetics, an aquaculture company that has always strictly controlled the quality of salmon eggs, now sells up to 10% of its salmon eggs to the land-based farming industry to improve the yield and quality of “land-based captive salmon. ”
People from all walks of life, through their own efforts, hope to work for the welfare of salmon, no longer be poisoned by the lust of human words, even if they reproduce artificially, they can also maintain their physical and mental health, and achieve the true meaning of "sustainable food" on earth.

Proteon Pharma to set up plant in Maharashtra

To produce antibacterial solution for livestock by 2023 and tap neighbouring countries

Poland-based Proteon Pharmaceuticals (India) plans to set up a fully functional plant in Maharashtra to produce antibacterial solution for livestock by 2023.

The company is a global leader in bacteriophage technology for livestock farming and aquaculture and aims to improve the food safety standard of animal products by reducing the usage of antibiotics and antimicrobial resistance (AMR) risk in poultry, dairy and aqua.

It provides an innovative, safe and effective antibacterial solution as bacteriophages which are an alternative to antibiotics to control the pathogenic bacteria.

The company is also looking to scale up its operations in South-East Asia, especially India, Bangladesh, Nepal, Sri Lanka, Thailand, Vietnam and neighbouring countries.

Sachin Ingewar, Regional Sales Director, India Subcontinent and South East Asia Region, said the company will strengthen the base of channel partners and is in talks to commence distribution of products in other APAC countries.

The growing demand for packaged and processed meat has pushed the livestock farm owners to produce antibiotic-free meat to match consumers’ demand. However, bacteriophages being an innovative new product for the Indian market, the acceptance of the product has been slow as customers are not fully aware of the benefits.

“Switching over from a traditional medication method to a relatively new concept is about a change in mindset and this is the only challenge," he said.

Major infection

Diseases caused by Salmonella and E. coli are the major challenges faced by poultry producers. The infection caused by these bacteria not only impacts poultry’s health but also the profitability of the producer and consumers health.

Proteon introduced Bafasal+G® into the Indian market few years back and last year Bafacoltm was launched as a feed additive for poultry to control infection.

“We have also introduced Bafador for aquaculture to control Pseudomonas and Aeromonas challenges, and will soon be launching Bafacam to control mastitis in dairy animals. There are also many other products in the pipeline to enhance the profitability of the farm owners,” said Ingewar.

Farming: Cultivated fish cooked without being sold
Do you want to eat fish, can you not catch it?
Is there any food in the world that is completely free from contamination?
Earlier this year, Sushi Lang ’ s parent company, FOOD & LIFE COMPANIES (F & LC), announced a partnership with BlueNalu, an American cell culture seafood company, to develop cell culture bluefin tuna.
“It ’ s a bit of a fight, of course, but there ’ s also the taste of fish, and there ’ s also the taste of melted fish, and there ’ s still a distance from the real fish. ” Miriam Leung, chair of the Food and Environmental Hygiene Advisory Committee and marine biologist, read online about the 3D printing of cultured fish chops by Israeli company Steakholder Foods in collaboration with Singaporean aquaculture fisherman Umami Meats. Think like it.
Can cell culture fish replace existing marine fishing and aquaculture in the future?
Animal cell culture is "theoretically real meat"
Local cultured meat startup Avant Meats invited local chefs to cook their cultured fish steak last year, when the chef commented in an interview with Reuters, “Before I cooked it, the fish steak was very hard, but after cooking, it felt like real fish, and the taste was no different from normal fish. ”
There are currently no cultured fish on the market. Singapore, which has approved the sale of cultured meat, only cultured chicken is available. Ms Leung laughs that she has never eaten it, and can only imagine it from online reports and food reviews.
Japan began discharging nuclear sewage from Fukushima last Thursday, and the Hong Kong government announced a ban on the import of aquatic products from 10 Japanese prefectures on the same day, sparking public concern about the safety and supply of aquatic products.
Sushi Lang ’ s parent company, F & LC, called to ensure a stable supply of seafood, and worked with BlueNalu to develop cell culture for bluefin tuna.
How is cultured fish made?
High tech costs are a moral issue.
Add a little glucose, a little amino acid, and a little vitamin to a small culture medium, so that the cells can eat good food and eat more meat.
Plant-based meat (plant-based meat) What is “clean meat ” (also known as laboratory cultured meat, test tube meat, etc.)? The principle is to extract muscle cells from living animals, add cell culture liquid to the anaerobic culture base to cultivate, and then 3D print the cells into muscle and fat tissue, and then use plant extracts (such as alginate, for food)." Their genes are the same as those of the animals extracted from the cells, and in theory they are real meat, "said Chen Xueyi, co-founder of Avant Meats." As long as a cell is healthy, a cell can grow to tens of tons. "Microbes fall into the instrument, and everything starts from scratch.
There is enough nutrition, although the cells reproduce quickly, but 3D printing and the cell growth process in the biological reactor takes time, Liang Mei Yi is not optimistic about the production efficiency of cultivating fish chops.
It sounds so familiar, isn ’ t it exactly the principle of artificial skin? To make a piece of meat that can be eaten and digested, it is impossible to imagine the cost of using such high-end biomedical technology.
“The temporary cost is three to five times more expensive than regular fish, ” says Chen.
It turns out that the most common nutrients in cell culture solutions come from the expensive fetal bovine serum, which is taken from pregnant cows and means killing a cow and its fetus, causing moral controversy. Although research has been done to replace it with a plant-based medium, the cell growth rate is not as fast as fetal bovine serum. Avant Meats still develops its own plant protein to replace fetal bovine serum, but it still has to this day. A big problem.
Growth Hormone or Residues in Cleansing
When it comes to cost, in addition to the cell culture solution, the laboratory configuration is also very careful, the cells must be placed in a thermostat with adjustable temperature, while ensuring that the container is completely sterile.
The growing environment is stable, not touched by a bit of dust, laboratory grown meat has never been contaminated in theory, and food safety is guaranteed.
However, in order to stimulate cell growth, different growth factors (growth factors) will be added to the cell culture solution, including hormones. Even after the cell is 3D printed into muscle and fat tissue and then made into meat chops, these hormones may still remain in it, and people may be at risk of cancer after eating.
“The food supply chain is very fragile, one wind is buried, one epidemic outbreak, and marine pollution is nothing. ” Chen Hsia-yi remembers the supermarket rush more than a year ago, when the rumors of a“ prohibition order ” were spread in Hong Kong, and people rushed to supermarkets to “supply ” to prevent food from being cut off. Food is precious.
The term “food crisis ” has become an international topic, starting with the COVID-19 pandemic that has ravaged the world, the still unfinished Russia-Ukraine war, and the continued extreme weather. Chen said people realize that“ they can ’ t buy food without money ” and should explore the possibility of lab-grown meat.
Aquatic food supply challenges
The world population continues to rise, and the consumption of aquatic food has increased significantly.
Global consumption of seafood (excluding algae) has grown at an average annual rate of 3% since 1961, and the population has grown at a rate of 1.6%.
In per capita terms, the consumption of aquatic food has increased from an average of 9.9 kg in the 1960s to 20.2 kg in 2020; the total consumption of aquatic food is expected to increase by 15% in 2030, reaching 21.4 kg per capita.
In 2017, for example, Hong Kong people ’ s per capita consumption of seafood was 66.5 kg, more than double the global consumption of seafood of about 20 kg per capita.
According to the Food and Agriculture Organization of the United Nations (FAO) Statistical Yearbook 2022, the global total production of fisheries and aquaculture (excluding algae) is currently 178 million tons. To catch up with the increase in protein demand due to population growth, the total production will increase to 200 million tons in the next few years.
About 90% of the world ’ s fish resources have been overexploited or even fully exploited. The FAO report on the state of world fisheries and aquaculture 2022 mentioned that fisheries resources continue to decline due to factors such as overfishing and pollution. In 2019, the proportion of fish stocks in the bio-sustainable level fell to 64.6%, down 1.2 percentage points from 2017. Challenge.
In order to stabilize the supply, many countries have gradually developed aquaculture and cell culture seafood, hoping to eat seafood with no difference in taste and taste without endangering the marine ecology.
No energy production, no fish farming.
Avant Meats specializes in the development of cultured fish and flower glue, with laboratories and R & D teams both locally and in Singapore.
“Singapore has always done well, ” Ms Leung said, pointing out that Singapore has always focused on innovation and technology. After years of research and cultivation of meat, Singapore became the first country in the world to approve the sale of cultivated meat in 2020.
As for June this year, the US Department of Agriculture also approved two California companies, Upside Foods and Good Meat, which received safety certification from the Food and Drug Administration last year, to sell the first batch of cell-grown meat in the country.
"The cost is too high, it (cell culture meat) with 3D printing technology is relatively slow to produce, and the yield is very dependent on the size of the bioreactor."
However, technology is changing with each passing day. “If Hong Kong develops cell-cultured meat and creates a new industry, technological breakthroughs are within reach, ” Ms. Leung said of the new industry, Bioengineering.
There is no bioengineering industry in Hong Kong, and naturally there is a lack of relevant talents. “We have tried to hire people in Hong Kong, it is very expensive to hire foreign talents, and it is very expensive to arrange accommodation, ” Chen said. Therefore, Avant Meats ’ cultured fish is mainly produced in Singapore, and Hong Kong is researching the formula of cell culture solution.
Hong Kong Enterprise Sing Chau Licence
Target sales next year.
Even if the cells are grown and sold in Hong Kong, will the public accept it?
“Honestly, not many people in Singapore have heard of cultured meat, it is the local government that approves the sale, and the people slowly accept it. ” Chen has contacted investors in the United States, Singapore, the Mainland and Hong Kong and found that there is not much interest in their technology in Singapore compared to the other three places.
As more countries around the world approve the sale of cultured meat, the level of acceptance will probably increase. "I think we need to study step by step. If the research results are positive and can be mass-produced, we will have the opportunity to discuss with the government the feasibility of approving the consumption and sale of local cultured fish." CITES regulates and monitors Sumei to reduce fishing at sea.
Although cell-grown seafood can reduce the marine ecological damage caused by wild fishing and live seafood cultivation, the animal protection organization Earth Care believes that cell-grown seafood production will still have other environmental impacts, including energy and resource consumption, and waste discharge.

What health concerns are there specifically related to additives in farmed salmon feed?

Insect-based proteins, derived from black soldier fly larvae, are emerging as a sustainable alternative in salmon feed, offering an eco-friendly option that avoids the use of wild fish or soy, though their long-term health impacts on consumers remain under study.

Insects food farmed fish in France
RITEL, France – A plant in the French region of Ardennes is breeding a black soldier fly, which converts agricultural waste into proteins used to feed pets, especially farmed fish, in a market that is booming worldwide due to rapidly increasing demand.
Rafael Semia, director of the Agronotris plant in Ritel, which will release its first batch of insect flour this summer and aims to produce 5,000 tonnes of it in 2024, explains that “the growth of aquaculture is phenomenal, which means we need raw materials to feed these breeding farms. ”
Last week, the company announced the construction of a second plant at Ritel, which will begin next year, to convert “more than 280,000 tonnes ” of organic waste into“ 30,000 tonnes of flour, ” without specifying at what date or amount of investment.
There is no interest in feeding fish with fish that can be eaten directly by humans or with soybeans that are widely imported.
Under recent changes to European rules, more than 5 percent of fish consumed in the EU could come from farms using insect-based proteins by 2030, according to estimates by the pro-insect flour lobby group in Brussels.
Existing farmed fish diets are made partly from wild fish.
International NGOs have for years denounced this contradiction, which they blame for overfishing, with dire consequences for ecosystems, the marine food chain and the livelihoods of local populations.
Therefore, the insect meal represents an alternative being developed in France from three players that are now in the manufacturing stage: Insect, Innovavid and Agronotrice, which raised 100 million euros in 2021 and finally signed a contract worth “tens of millions of euros ” with Biomar.
This Danish company, a world leader in the manufacture of farmed fish feed and salmon in particular, has decided to invest in this project.
“There is no interest in feeding fish with fish that can be eaten directly by humans ” or with soybeans, which are widely imported and whose intensive farming contributes to the expansion of deforestation, says Biumar ’ s marketing director Catherine Briar.
In Ritel, inside a transparent container, there are like thousands of semolina seeds.
Cedric Oriol, co-founder of Agronotris, says, “These larvae have just hatched.
Today, it weighs 15 micrograms, and this weight will double ten thousand times in just two weeks.
So 100 grams of larvae will become a ton of larvae in two weeks. ”
The rapid growth of black soldier fly larvae is one of the reasons the company chose this non-invasive species known as the composting queen.
French factories raise black soldier flies that convert agricultural waste into proteins used to feed animals and fish
This choice, along with the dough recipe or optimal conditions for the marketing of the production, has been the subject of 12 years of research at a laboratory in Toulouse, according to the company.
After two weeks of growth, 98 percent of the larvae are crushed to make proteins, while 2 percent are kept for use in reproduction.
Inside one of the cages, where adult flies move, Antoine Riebois, wearing a hat covered with insects, explains that “the main activity here is to lay eggs, and the goal is to recover as many eggs as possible. ”
The black soldier fly can lay between 600 and 1,000 eggs in its short two-week life.
Another use associated with fly breeding is a mixture of insect droppings known as feras, which is an excellent fertilizer for agriculture.
The company aims to produce about 16,000 tons quickly.
The use of this waste to manufacture human food is not expected any time soon.
Rafael Semia, director of the plant, said: “It will take time, but tomorrow the actors in the insect branch will be at the forefront of human food processing. ”

Preservatives are used in salmon feed to extend shelf life and inhibit bacterial growth, ensuring the feed remains safe and effective for consumption by farmed salmon.

Health Care Network
2021-11-09 08: 31: 00
[Health and Medical Network / Reporter Zeng Zhenghao reported] This year, I am afraid that I will encounter the anti-baby phenomenon, and in the face of a harsh winter that is very likely to come, I will bring three or five friends to a hot pot gathering to warm my stomach and heart on a cold day, which is something many people can ’ t wait to put on the calendar.
However, in recent years, the awareness of food safety has risen, and the public has gradually begun to pay attention to the use of food additives in processed foods. Many of them are also worried about the production of hot pot materials, or the use of soup powder and soup pieces to brew hot pot soup.
This is an advertisement, please continue reading.
Careful use of food additives can help to inhibit bacteria and improve taste
Natural hot pot ingredients such as fresh vegetables, meat and seafood are certainly the healthiest, but hot pot is often eaten with some processed food hot pot ingredients.
The Food and Drug Administration (hereinafter referred to as the Food and Drug Administration) refers to international standards and has formulated a "food additive use scope and limit and specification standards". As long as it is used correctly and lawfully in accordance with the standards, there is no risk of harm to health.
For example, in order to extend the shelf life and easy storage of fish products, preservatives such as "adienoic acid" and "benzoic acid" may be legally added; in order to increase the taste, Kadelan may be added.
In order to enhance the flavor of hot pot soup, seasonings such as "aminoacetic acid", "5 '-hypoxanthine nucleoside disodium phosphate" and "5' -hypoxanthine nucleoside disodium phosphate" may be added.
The public has a negative view of food additives, but the prudent and legal use of food additives can help food to inhibit bacteria, enhance flavor and taste, so that consumers can enjoy safe, high-quality and diverse food.
Consumers have the right to "know" the ingredients of the soup base need to be open and transparent
Some diners must eat hot pot restaurants that use natural ingredients to boil the bottom of the soup. How do I know the ingredients of the soup?
The Food and Drug Administration maintains national health and food safety, and also attaches importance to the right of consumers to "know".
It specifies that all ingredients in hot pot soup in restaurants should be fully developed, and the contents of the main ingredients or flavor seasonings should be clearly marked, so as to prevent unscrupulous operators from falsely claiming that it is high quality food materials that take time to cook, and to avoid commercial secrets.
In order to ensure the health and safety of people enjoying hot pot, the health authorities regularly conduct special audits on hot pot restaurant operators, including food additives in processed foods and seasonings, and hot pot soup bottom labeling, to ensure food safety.
You can cook hot pot at home, and you can choose the ingredients clearly.
The Food and Drug Department (FEHD) reminds consumers to buy products with good reputation and clearly marked, and to buy less products in bulk, from unknown sources or without clearly marked food ingredients, shelf life and manufacturers.
In addition, hot pot food materials must be cooked, fresh ingredients and cooked food clamping tableware do not mix, to avoid cross contamination caused by food poisoning.
In addition, whether it is a Man-Han full table or porridge small dishes, master the principle of balanced diet, and do not drink overeating, is the only way to maintain health.

Journalist Hsu Yu-jae / Kaohsiung reporting
The Taiwan Consumer Protection Association recently inspected 50 pieces of fresh tender tofu in the middle and large traditional markets in southern Taiwan. It was found that Kaohsiung Bean Market, Pingtung Jianhua Market, and Pingtung North District Market each had a stall selling benzoic acid, a preservative that cannot be detected.
Biotechnology experts said that large doses of benzoic acid are feared to brew stomach pain, nausea and vomiting, and cause gastrointestinal mucosa damage.
“Don ’ t mess up, the government will step up control! ” The Taiwan Consumer Protection Council today released 15 items in Tainan, 25 in Kaohsiung, and 10 in Pingtung. A total of 50 tofu stalls in traditional markets inspected the preservative benzoic acid test results.

Benzoic acid was found to be 0.15g / kg in tender tofu sold by a stall in Kaohsiung Meat Bean Market; 0.53g / kg in plate tofu sold by a stall in Pingtung North District Market in China; and 1.71g / kg in plate tofu sold by a bean product stall in Guangming Street, Jianhua Market in Pingtung.
Hsu Pang-han, CEO of the Taiwan Consumer Protection Association, says that although benzoic acid can be added to dried bean curd, even if it is added to dried bean curd, it cannot exceed 0.6g / kg.
▲ Three tofu stalls in Gaoping tested the preservative benzoic acid.
Liu Hsiao-han, a medical professional member of the Taiwan Consumer Protection Association and an assistant professor of the Department of Biotechnology at Italian University, said that benzoic acid is a white coarse powder with a slight crystalline and special benzoic acid odor or choking odor, which has the effect of inhibiting the growth of fungi, bacteria and molds.
Stimulation, nausea, vomiting, and stomach pain may occur with ingestion. In large doses, throat pain, stomach pain, nausea, vomiting, and possible allergic reactions may occur.
And the substance will cause moderate discomfort in the gastrointestinal tract, may cause serious damage to the mucosa, and it is harmful to swallow in large quantities.
Liu Xiaohan pointed out that the Taiwan Food Safety and Health Management Law has clear regulations on the use of benzoic acid in different foods, which are aimed at balancing the effect of food preservation and consumer health and safety.
The World Health Organization (WHO) recommends a tolerable daily intake of benzoic acid of 5 mg per kilogram of body weight.
For an adult of 60 kg, the safe daily intake is about 0.3 grams.
Consumers should pay attention to reading food labels and reasonably choose foods containing benzoic acid.
Taiwan Consumer Protection Association calls on companies not to add illegal preservatives, so as not to violate the provisions of Article 18 of the Food Safety Law on food additives, the scope of use, and the limit. Violators may be fined between NT $30,000 and NT $3 million in accordance with Article 47 of the Law.

Additives like vegetable oils, soy proteins, wheat gluten, and corn gluten meal are often used in salmon feed to reduce reliance on feed-grade fish, which can harm ocean ecosystems by disrupting food chains and biodiversity.

Some farmed salmon have been found to contain elevated levels of polychlorinated biphenyls (PCBs), which are environmental contaminants linked to cancer risks, raising concerns about the indirect health impacts of feed additives and farming practices.

A medical study published on Monday warned that overeating salmon raised in farm ponds could lead to cancer.
The Daily Express newspaper pointed out that "some previous studies found that salmon, jam in ponds, which is widely consumed around the world, doubles the risk of prostate cancer," pointing out that "salmon is a useful food source for health because it contains omega-3 fatty acids."
"While one salmon is caught in open water, like the seas, the other is bred in tight spaces (farms and ponds), which could have implications for human health," the paper said.
Studies have found that PCBs in farm-raised salmon were about 8 times higher than concentrations in wild salmon, adding that PCBs have been banned for commercial use for decades, but their effects can still be found in the environment, which may adversely affect human diet and therefore health.
According to a study by the Environmental Defense Fund, eating salmon raised in farm ponds on a regular basis may increase the risk of cancer after multiple cases of contamination have been detected in the United States and other countries.
"Medical scientific findings, published in the Journal of Medical Sciences, suggest that cheap farmed salmon sold in stores may do more harm than good."
“Risk analysis suggests that consumption of farmed Atlantic salmon may pose health risks that detract from the beneficial effects of fish consumption, ” the study said.
Eating farmed salmon more than once a month may be enough to increase the risk of cancer.
"In multivariate analyses, men with the highest concentrations of PCBs were twice as likely to develop prostate cancer than men with the lowest concentrations."

What health concerns are there specifically related to additives in farmed salmon feed?

In certain cases, harmful practices such as feeding fish with untreated waste from chicken slaughterhouses have been reported, leading to bacterial contamination and increasing the risk of chronic or carcinogenic diseases in humans consuming these fish.

Detecting 6 fish pores in Hama that feed its fish with waste that leads to carcinogenic diseases
The Director of Internal Trade and Consumer Protection in Hama Riad Zeyoud revealed the seizure of 6 fish feeds farmed fish harmful to humans when eating them.
Zeyoud explained that three fish were seized in the Kazuo Valley, providing the fish of breeding with non-heat-treated residues, which may transfer the spores of Salmonella and Escherichia coli, which cause various diseases and health problems to humans when eaten by the consumer who buys and feeds those fish.
In the same context, the head of the Consumer Protection Department in Hama, Dr. Jaafar Al-Safaf, pointed out that a fourth fish was seized in the same area in violation of feeding the fish, the waste of chicken slaughterhouses that are not heat-treated, pointing out that these fish were not confiscated because they could not be transported and are in the process of growth.
Al-Safaf also pointed out in the same context that the seizure of the Shorouk fish in the Kazuo Valley was also in violation of feeding the waste of the chicken slaughterhouses without heat treatment, with the amount of one and a half tons of catfish, and the owner was fined a total value of 12 million Syrian pounds, in addition to organizing the seizure of Aboud fish in the same area and the type of the violation. Syrian pound.
After communicating with the veterinarian Bilal Ismail, he pointed out that the food mentioned (the waste of broiler slaughterhouses) provided to fish is for obtaining animal protein, which works to increase the food conversion within a short period, but when resorting to this method must be subjected to microbial and viral surveillance, without which may lead to common diseases between fish and consumers (chronic or carcinogenic diseases).
He added that these residues, if their bacterial virulence is large, may lead to the occurrence of the breeder in large economic losses on the one hand, and on the other hand will be a health disaster transmitted to human consumers even if the disease is controlled through the use of antibiotics after trespassing with waste, and known fish that are given these residues by their meat and feeling unpalatable to human consumption.

Drug-resistant sea lice an increasing problem for B.C. fish farms, new study finds

By Melanie Nagy

Click here for updates on this story

    May 14, 2022 (CTV Network) — Every spring, endangered juvenile wild salmon migrate from B.C.’s rivers to the Pacific Ocean, but their numbers are dwindling and some fear sea lice parasites are increasingly to blame. Sea lice are tiny, oval shaped crustaceans that can cling to the backs of wild salmon, feeding on their skin, muscle tissue and blood. Adult fish are generally not harmed when a few lice attach themselves, but juveniles with underdeveloped scales can be harmed or killed when heavily infested. While the parasite occurs naturally in the waters off B.C.’s coast, there’s long been concern over outbreaks on aquaculture farms where open-net pens make it possible for lice to move from farmed fish to young migrating salmon. “Salmon farms act as this year-round reservoir for sea lice, potentially providing sea lice to wild juvenile salmon when they wouldn’t normally get them,” conservation biologist Sean Godwin said. Godwin is the lead author in a recent study that looked at the state of sea lice in the Pacific Ocean. Along with his fellow researchers, he found the parasite is increasingly becoming resistant to one of the main tools the industry relies on to combat the problem. “Our paper found that this tool, which is a pesticide known [as] SLICE, or emamectin benzoate, is becoming less effective and that sea lice are developing resistance to it on farms here,” Godwin said. To assess parasite resistance, “bioassay, treatment and salmon-louse count data from 2010 to 2021” were analyzed. During that time, the researchers found a notable decrease in the effectiveness of SLICE. “It is going to be more difficult for salmon farms to control sea lice outbreaks on their farms,” said Godwin. In the province’s stunning Clayoquot Sound, Bonny Glambeck routinely uses a fine-mesh net and a sample cup to test the waters near fish farms. Glambeck heads the Tofino-based conservation society known as Clayoquot Action and every year she monitors industry lice counts and tracks wild salmon infestations. “The control of sea lice on fish farms is something I do not believe the industry has ever been able to crack,” she said. “Parasites like these sea lice proliferate on these farms and then they can pass them on to wild salmon. With that, we feel that every year that goes by and these farms are allowed to pollute the waters with these infestations, they are just wiping out another generation of wild salmon.” Fisheries and Oceans Canada requires all fish farms in Canadian coastal waters to have a sea lice management plan. The federal department also places a limit of three lice per salmon during the spring when young salmon are out-migrating and are most vulnerable. In addition to that, the industry publicly reports lice counts on individual company websites every month. “The worry is that those lice levels might accumulate and then be released back to affect wild migratory salmon. The science doesn’t support that, but the concern exists so the industry responds to that,” said Brian Kingzett. Kingzett is the science and policy director with the BC Salmon Farmers Association. He says the industry has warned the federal government for years about the waning efficacy of SLICE, and has long called on Ottawa to approve new pesticide options. “There are other anti-parasite agents that have been approved in other areas of the world and we would certainly like to add that to our toolbox.” While SLICE is the only approved pesticide in Canada, it is not the only option for a fish farm struggling with a lice infestation. Kingzett says other environmentally friendly methods include the use of specialized delousing boats. One readily used vessel can suck fish from ocean-based pens into tanks where pressurized water is used to forcibly remove any attached lice. According to the industry, any dislodged bugs are collected by filters for disposal so they are not reintroduced to the marine environment. “During the last five years, the industry has spent about $100 million on importing new technologies,” Kingzett said. “Fish farming is an important industry in B.C. because we are facing a global seafood shortage and the farming sector is looking to provide sustainable, high-quality product.” The industry, however, is controversial and there’s been an ongoing battle to have all fish farms in the province removed. Earlier this month, there was a large protest in Tofino involving Indigenous leaders, conservationists and environmentalists. The group took to the waters near a local fish farm to voice their opposition to the industry and call on Ottawa to evict them. “It is a do-or-die moment for the salmon farming industry,” said Alexandra Morton, who is an independent biologist and longtime wild salmon activist. “We need to do whatever we can to save wild salmon populations because they are sadly on the verge of extinction.” In response, those in support of fish farms argue they are not a direct threat to wild salmon and are a vital industry. According to the BC Salmon Farmers Association, there are nearly 5,000 jobs linked to fish farms and at least $1 billion “in economic activity” is generated annually. Despite that, Ottawa has previously announced that it’s committed to phasing out open-net salmon farms in B.C. by 2025. In addition, it’s uncertain if 79 federal fish farm licenses expiring in June will be renewed.

What countries or jurisdictions have regulations concerning additives in salmon feed?

Labeling requirements for farmed salmon products often mandate the disclosure of feed additives, especially if they include substances that could pose health risks, such as banned drugs or preservatives like sulfur dioxide.

More News Clips
The whole egg noodle (wide strip) of the sushi brand was found to contain sulphur dioxide but was not marked and must be discontinued for recycling.
A pre-packaged whole egg noodle sample from Chai Wan Supermarket was found to contain the preservative sulphur dioxide. However, the food label of the sample did not indicate the type of action and the name of the additive. People with allergic reactions may experience symptoms such as asthma, headache or nausea after consumption.
The Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department (FEHD) said today (19) that it was aware of the relevant irregularities of the merchants and the general agent of the products involved, Xin Shun Fook Food Co., Ltd., and instructed them to stop selling and remove the affected batches of products.
The product in question is “Whole Egg Noodle (Wide Stripe) ” of Shoutao brand, with a net weight of 454 grams per bag. The best date for consumption is December 1, 2022, and the country of origin is China.
The CFS took samples of the above products from a supermarket in Chai Wan under the Constant Food Surveillance Programme and the results showed that the samples contained sulphur dioxide. Although the levels were lower than the maximum allowable levels specified in the Preservatives in Food Regulations, the food labels of the samples did not indicate the type of action and the name of the additives.
Sulfur dioxide is a preservative that can be used in different kinds of foods such as dried vegetables, dried fruits, pickles and salted fish products.
Sulfur dioxide is soluble in water. Washing and cooking can remove most of the sulfur dioxide from food. However, people who have an allergic reaction to sulfur dioxide may experience symptoms such as asthma, headache or nausea after consumption.
According to the Food and Drugs (Composition and Labelling) Regulations, if prepackaged food sold in Hong Kong contains more than 10 parts per million sulfites, the type of action and the name of the sulfites concerned must be specified in the ingredient list.
Offenders are liable on conviction to a maximum fine of HK $50,000 and imprisonment for 6 months.

Consumers can identify farmed salmon products with minimal harmful additives by prioritizing those with production traceability marks, QR codes, or certifications such as CAS, which ensure transparency and safety in sourcing.

Content: The Food and Drug Administration (FDA) today announced the results of the latest poultry and aquatic products residue sampling, a total of 2 of the 787 samples in Taiwan were not qualified.
The unqualified products are the freshly peeled shrimps from the New Taipei Jinshan Farmers Association, and the black-bone chicken from the Penghu Bishan Company, all of which are from Tainan.
Among them, the animal drug detected in shrimp is Lincomycin, a banned drug in China, which has sold more than 28 kilograms, while the black-bone chicken is three times more than trimethoprim, and all 21 kilograms of imported products have been sold.
In order to safeguard the safety of consumers' consumption of livestock and aquatic products, the Food and Drug Administration, in conjunction with the health departments of local governments, conducts sampling for importers, wholesale markets, traders, traditional markets, restaurants, supermarkets and other places to check whether the residues of animal medicines and pesticides meet the standards.
In July and August, a total of 787 poultry and aquatic products were smoked, of which 236 were poultry products, 425 were livestock products, and 126 were aquatic products.
Lin Jinfu, deputy director of the Food and Drug Administration, said that the total pass rate of the sample test was 99.7%, and the unqualified products were freshly peeled shrimp sold in the fresh supermarket of the farmers' association in Jinshan District of New Taipei City, and the black-bone chicken sold by the Bishan business in Penghu County.
Among them, prawns were found not to use the animal drug lincomycin, and the detection amount was 0.002 ppm.
Lincomycin has antimicrobial effects on gram-positive bacteria, gram-negative bacteria, mold plasma and porcine red dysentery spirals. However, excessive consumption by consumers may lead to gastrointestinal discomfort, and severe cases may affect kidney function.
As for the black-bone chicken, it was detected that trimethoxypyrimidine exceeded the standard.
The residual tolerance of trimethoxypyrimidine is 0.05 ppm, and the detection amount of this time is 0.2 ppm, which is equivalent to exceeding the standard by 3 times.
Trimethoxypyrimidine has antimicrobial effects on gram-positive and negative bacteria, and is usually combined with sulfonamides to enhance the antimicrobial effects of sulfonamides. Common side effects include nausea, vomiting, and allergies.
If used in excess, it may cause gastrointestinal discomfort and affect kidney function.
The two unqualified products are from Tainan, the supplier of shrimp is Tainan Wujin Aquatic Company, and the chicken is from Tainan City, Luo Mou.
According to the statistics of the health unit, a total of 28.8 kg of shrimp was imported, 200 grams were recovered this time, and the rest has been sold, while the black-bone chicken was imported 21 kg, which has all flowed into the hands of consumers.
Lin Jinfu said that in response to the case, Tainan Health Bureau has been fined, of which Wujin Water was fined 60,000 yuan, and Luo Mou because he is not a company, the amount of the fine can be reduced according to the circumstances, and a total of 30,000 yuan was fined, and both companies were first offenders.
The Food and Drug Administration recommends that consumers should avoid purchasing livestock and aquatic products of unknown origin, and give priority to businesses with CAS, production and marketing history marks, production traceability QR code or good reputation to protect consumer rights.

The Taipei City Health Bureau pointed out that a total of 30 fresh water products were sampled, including 5 deep-sea fish, 10 farmed fish, 5 shellfish, 5 shellfish, 5 crustaceans, and 5 cephalopods.
Test results 1 piece of "flat crab" detected heavy metal cadmium 0.6 mg / kg (standard: 0.5 mg / kg), does not comply with the "food contaminants and toxins hygiene standards" provisions, in violation of article 17 of the Food Safety and Health Management Law, in accordance with article 52, paragraph 1, paragraph 2 of the same law should be confiscated and destroyed, in accordance with article 48, paragraph 8 of the deadline for correction, the new punishment. A fine of less than $3 million was imposed.
The other one was found to be leucocrystal violet (LCV) 0.6 ppb (standard: not to be detected), which did not meet the "animal drug residue standard", violated the provisions of Article 15, paragraph 1, paragraph 5 of the Food Safety and Health Management Act, and was fined between NT $60,000 and NT $200 million in accordance with Article 44, paragraph 1, paragraph 2 of the Act. Article 52, paragraph 1, of the Act stipulates that the product shall be confiscated and destroyed.
In view of the heavy metal content of the food was found to exceed the standard, Courtyard by Marriott Liufu Hotel issued a statement that this frozen flat crab was sent to the Ministry of Health and Welfare certification unit for inspection and approval, and will then communicate with the Health Bureau to clarify.
According to the Taipei City Health Bureau, heavy metals can enter the human body through food, dust inhalation, skin contact and drinking water. The source of heavy metals in aquatic products is mainly due to the growth of contaminated water. The risk.
As for the "leucocrystal violet (LCV)" detected by yellow fish, although it can prevent aquatic products from being infected by mold and microorganisms, it is carcinogenic to the human body, so it is not allowed to be used in edible aquatic products, and it is an animal medicine that cannot be detected.
The Taipei City Health Bureau reminds that the legal use of approved drugs in the breeding industry, in addition to the animal object, age, dosage, etc., must also comply with the drug suspension period, so as to ensure the safety and health of the product.
The Taipei City Health Bureau recommends that vendors obtain independent inspection reports from large plates or suppliers, and urges consumers to choose companies with good production history or reputation for aquatic products, avoid purchasing products of unknown origin, and diversify their choice of fish products.

The EU must not support intensive fish farming — it's not sustainable

Free Article

The Hungarian presidency of the Council of the European Union, which will run between 1 July and 31 December 2024, has announced in its programme that it will pay particular attention to the development of “sustainable and competitive aquaculture”, arguing that “it is the animal protein production sector with the smallest environmental footprint.”

Beyond a supposedly low carbon footprint, aquaculture is also presented as an alternative to mitigate declining wild fish catches. However, under the term “aquaculture” we find various production models – some of which are more environmentally benign when conducted at appropriate scale, such as the cultivation of mussels, clams, and oysters, and some of which come with significant damaging impacts.

Many European consumers who want to eat fish from sustainable sources believe farmed salmon, trout and seabass are sustainable choices. But the intensive farming of carnivorous fin fish is neither socially nor environmentally sustainable.

The environmental impacts of this industrial production model include an increase in harmful algal blooms, a negative impact on sea grass meadows due to the accumulation of organic matter around farms, mass fish die-offs, the use of the harmful substances such as carcinogenic formaldehyde or antibiotics, and water pollution, creating dead zones on the sea bed underneath the farms. Adding to this, carnivorous farmed fish such as salmon and seabass require high volumes of fishmeal and fish oil from wild-caught fish in their feed.

In Europe, industrial aquaculture of carnivorous fish at sea is damaging the environment and displacing traditional activities such as coastal small-scale fisheries.

On the island of Poros, Greece, for example, the plan is to increase the area dedicated to open net pen carnivorous fish farms by 28 times. Yet, underwater video depicts that marine ecosystem near the current small-scale pens is completely dead from the waste and pollution of the farms, and local professional fishermen attest to a loss of wild fish since the influx of fish farms.

Beyond Europe, the production of fishmeal and fish oil necessary to feed carnivorous farmed fish is depleting wild fish stocks. This is the case in West Africa where the overfishing of small pelagics such as sardines and mackerel for industrial fish farms in Europe is undermining food security and the livelihoods of small-scale fishers and women fish-processors. Fish is taken away from people in low-income countries to feed the farmed fish which will be consumed in wealthy nations.

The UN special rapporteur on the right to food acknowledged this in his report to the Human Rights Council in early 2024: “Many farmed fish are carnivorous species that require feed products harvested from wild fish stock, thereby creating another source of pressure on wild fish stocks and disrupting ecosystems.

Moreover, global feed companies are exacerbating food insecurity in some communities. For example, over half a million tons of pelagic fish that could feed over 33 million people in the region are instead extracted from the ocean along the coast of West Africa and converted to fishmeal and fish oil, primarily in order to feed farmed fish and livestock, mostly in Asia and Europe.”

The current EU strategy for aquaculture does not respond to the social and environmental challenges posed by this sector and fails to clearly define what “sustainable” aquaculture is. In fact, in a special report on aquaculture, the European Court of Auditors (ECA) found that the European Union has been pouring funds into the development of aquaculture with little proof that this has contributed to the sector’s “environmental and social sustainability or its competitiveness.” The ECA report further highlights that “there are currently no indicators available to monitor the environmental sustainability of EU aquaculture.”

Under the agriculture and fisheries agenda, Hungary has reaffirmed its wish to support farmers, and fish farmers, through a “farmer-friendly European food system.” Rather they should support low impact small-scale fishers as primary food producers.

Under the Hungarian presidency, the EU should discontinue support for industrial aquaculture of carnivorous species and instead promote more sustainable small-scale aquaculture options that can co-exist instead of negatively affecting small-scale fisheries in Europe and beyond. If Europe wants to be a model in sustainable ocean governance, it must place small-scale, low-impact fisheries and aquaculture at the heart of its food policy.

Anticipating obsolescence: The next step to enhancing the sustainability of aquaculture

With growing concerns about the environmental toll of single species fish farms, a research project has been looking at the feasibility of introducing a more sustainable and potentially more profitable method of fish farming, using three complementary species.

Much as native American people planted squash, maize and climbing beans together to benefit each other, (often called the "three sisters"), farming finned-fish, shellfish and seaweeds together could benefit each other and reduce any environmental effects of fish farming. Small scale integrated multi-trophic aquaculture (IMTA), as the system is called, has traditionally been used at a small domestic scale in Asia, providing the farmer with more than one product to sell or use.

The feasibility study conducted by Bangor University and published in Ecological Modelling has identified the locations around the Atlantic coast which would be most suitable for IMTA, based on farming salmon, and Oarweed, a type of kelp seaweed commonly found in temperate Atlantic coasts. The research considered the natural distribution of the three species, whether suitable locations clashed with busy shipping lanes or marine protected areas and whether there was close access to sizeable ports in order to reach markets.

The western coast of Lewis in the Outer Hebrides, Scotland; Lough Swilly in County Donegal, Ireland, and the western coast of Brittany, northwest France were found to be the best locations to further develop IMTA based aquaculture.

As Conchúr Hughes of Bangor University's School of Ocean Sciences explained, "One of the problems with the type of single species aquaculture practiced in Europe is that excess food and feces can lead to deterioration of local ecology, while density can mean that aquaculture companies need to use antibiotics and other additives to maintain a healthy fish-stock.

"Mussels are filter feeders, they can be responsible for removing up to 54% of salmon waste materials from the , using it as energy to grow, while the oarweed removes soluble nutrients from the water column. Oarweed can then be farmed to use in a variety of products, from food supplements for human consumption or for fish farms, as a fertilizer or as an ingredient in pharmaceuticals.

"Each of these species complements the other and mitigates against problems."

IMTA-based aquaculture

Both salmon and mussels are important food sources in Europe, and while oarweed is not as yet, this is a sector that is expected to experience a rapid increase in demand in the coming years- and can provide an alternative sustainable source of fertilizer and other products.

Seaweed cultivation can also provide environmental benefits. The seaweed in the water acts as a buffer against as it approaches the shore, reducing the energy as it passes through the seaweed, much as trees act as a buffer against strong winds, which can help reduce erosion. It also elevates the pH and oxygenates the water.

Omega-3 enhancing additives in salmon feed, such as fish oil and vegetable oil, significantly influence the nutritional profile of farmed salmon by increasing levels of EPA and DHA, which are beneficial for heart health and cognitive function.

  • Fish-eaters benefit from two Omega 3 fatty acids – EPA and DHA – which can boost heart health and thinking skills
  • Researchers analysed packs of farmed Scottish and Norwegian salmon from 10 UK supermarkets
  • The best provided 67% of the recommended weekly Omega 3 but the worst only offered 26%

Premium farmed salmon may be no healthier than value brands when it comes to Omega 3, a study has shown.

Fish-eaters benefit from two Omega 3 fatty acids – EPA and DHA – which can boost heart health and thinking skills.

Researchers analysed packs of farmed Scottish and Norwegian salmon from 10 UK supermarkets.

The best provided 67 per cent of the recommended weekly Omega 3 but the worst only offered 26 per cent.

Fillets from two stores did not contain significantly more Omega 3 than non-premium products.

Farmed salmon tend to be fed a mixture of fish and vegetable oils but the latter lack the fatty acids found in seafood.

Study leader Dr Matthew Sprague, from Stirling University, said: 'The amount of EPA and DHA can vary based on the cut of salmon, as well as what it was fed, but farmed salmon is still high in nutrients.'

Salmon not only contains Omega 3 but selenium and phosphorus, which are also important for health.

Andrew Opie, director of food and sustainability at the British Retail Consortium, said: 'Consumers take various factors into consideration when buying salmon, including its health benefits and the way it is produced, and they will weigh these up when choosing what to purchase in a supermarket.'

Salmon not only contains Omega 3 but selenium and phosphorus, which are also important for health

Phil Brooke, from Compassion in World Farming, said: 'Intensive fish farming is bad for fish welfare and the product only contains Omega 3 due to the wasteful consumption of feed containing fish oil.'

Wild salmon consume only fish oil, which they get from algae and smaller fish, but lose fatty acids from that fish oil, as they become leaner during the migration back from the sea to the river to spawn.

This means farmed fish, which are kept confined in cages within the sea, can contain more Omega 3 than the wild variety.

But vegetable oil is more accessible, sustainable, and also cheaper than fish oil for the expanding fish farming industry.

So more of this can be used, which substantially reduces the amount of Omega 3 in farmed salmon.

Farmed salmon often contains higher levels of omega-3 compared to wild salmon due to the controlled inclusion of fish oil in their feed, but the use of vegetable oils as a cheaper alternative can reduce omega-3 levels.

Health risks associated with omega-3 enhancing additives in salmon feed include potential contamination with heavy metals or pollutants in fish oil, emphasizing the need for regulatory oversight and quality assurance.

As people become more aware of their health, many people supplement fish oil. However, people often only care about the concentration when selecting fish oil products, but ignore other more important factors.
Chen Weijian, chief physician of the Department of Endocrinology and Metabolism, pointed out that although fish oil has many benefits, it is not good to eat, and a high concentration of fish oil is not equal to a high dose, and each person according to different physical conditions, such as pregnancy and lactation, the recommended amount of intake also varies from person to person.
In addition, there are food safety issues such as heavy metals, and there are international authoritative third-party impartial organizations for consumers to continuously test the quality of products, which is more trustworthy. Dr. Chen Weijian emphasized that when purchasing fish oil, we need to pay attention to 2 standards, one is to ensure that it is well absorbed and used by the human body, and pay attention to whether it has international authoritative certification and product history traceability after market supervision mechanism to ensure quality and safety.

Dr. Chen Weijian pointed out that fish oil is rich in omega-3 fatty acids that cannot be made by the human body. However, the absorption rate of fish oil is affected by many factors. It can vary due to stress, mood, and diet, which can affect the absorption of fish oil.
Amway ’ s Nutrilite brand launched a new fish oil, hoping to uphold the faith in the "post-market supervision mechanism" to continuously ensure quality standards, including the National Health Foundation twice a year unscheduled inspections of factories and processes, and the "International OMEGA-3 Concentrated Fish Oil Organization (GOED)". The process of fishing, extraction and manufacturing of finished products, in every aspect of the level of checks, detailed inspection records, the whole process can be traced back, so that consumers have more peace of mind.

ZTE and the Agricultural Science and Technology Research Institute jointly developed the first probiotics suitable for crops, livestock and aquatic products in China. After 3 years of field trials, it has proved to be helpful in preventing and controlling plant diseases, improving the immunity of pigs and chickens, and improving the quality and quantity of meat, and improving the breeding efficiency of lice fish and white shrimp.
With the support of the Ministry of Science and Technology, the two sides have implemented the "Application of Probiotic Microorganisms in Agriculture" project. The project has developed a series of bacteria strains for health care, crop safety, circular agriculture, livestock and poultry farming, and aquaculture.

President Xue Fusheng said that there are abundant agricultural biotechnology talents, and the Ministry of Education's advanced education program has been subsidized to set up three research centers, including the Prospective Plant Biotechnology Research Center, the Sustainable Agriculture Innovation and Development Center, and the Bird Genetic Resources and Animal Biotechnology Research Center.
He encouraged his colleagues to develop their expertise, cooperate more with corporate bodies, expand R & D energy, and fulfill the University ’ s social responsibility.
Vice President Huang Chen-wen says that in the past, probiotics were mostly used in a single industry. This project integrates labor in plant pathology, pesticide testing, aquatic and livestock farming, and fermentation mass production.
Hsingtao explains that the Bacillus subtilis series of bacteria, including liquid, powder and granular coating type microbial preparation, has been proved to be a plant protection agent, reduce the amount of pathogenic bacteria in crops, induce the pathogenic bacteria to self-apoptosis, and can also be used as an additive for livestock and poultry production and aquatic feed, effectively improving the growth of animals and plants.
In the prevention and control of plant diseases, Bacillus subtilis series products can prevent and control the growth of various crops, such as cucumber, strawberry and passion fruit, and can also degrade agricultural waste residues, pesticides marasone, tannin and dendrobium. Trisazole, a bactericide, solves the problem of potential pesticide residue safety in the recycling of agricultural by-product resources.
In livestock feed additives, the Bacillus subtilis series products are used in the breeding of lactation piglets, white meat pigs, and meat chickens.
It can improve the breeding efficiency, improve the carcass weight, meat quantity and quality of pork pigs, shorten the time of pork pigs to market, reduce the odor of pig and chicken feces, improve the environment of the feeding field, and improve the immunity of lactating piglets, and reduce the number of E. coli, a potential pathogen of diarrhea in pigs.
In addition to assisting in the development of the commercialization technology of the research results, it can also provide key fungus raw materials, preparation production process, physicochemical testing of the preparation, and microbial fertilizer toxicity testing.

Emerging technologies in salmon farming, such as integrated multi-trophic aquaculture, aim to reduce reliance on harmful additives by farming complementary species like mussels and seaweed alongside salmon.

Insect-based feed ingredients, such as those produced by Ÿnsect, are being explored as sustainable alternatives to traditional fishmeal, offering benefits like faster fish growth and reduced feed consumption.

Title:

Content: World’s Largest Insect Farm to Open in France

Once fully operational, the massive vertical farm will produce 200,000 tonnes of insect-based ingredients a year.

Ÿnsect, one of the world’s largest insect rangers, is betting big on bugs to help push the world in a more sustainable direction.

Founded in 2011, the company is fast approaching its goal of opening the world’s largest insect farm and dramatically scaling up its operations. Located about an hour north of Paris, the state-of-the-art facility will leverage automated systems and vertical farming techniques to raise mealworms (Tenebrio molitor) and enable the production of over 200,000 tonnes of insect-based ingredients per year. The site, estimated to be completed by the end of 2022, will join two other Ÿnsect facilities already operational in France and the Netherlands.

"It’s an automated warehouse, very similar to an Amazon warehouse, where instead of storing stuff, we are storing live insects," Ÿnsect CEO and co-founder Antoine Hubert told Time last year. "There is a climate-control system which is highly complex to maintain temperature and moisture from zero to 30 meters high. All operations are automated. Anything that you do on [an insect] farm is done with robots."

Feed for Fish, Fertilizer for Plants, Burgers for Humans

For the past decade, mealworms cultivated at Ÿnsect’s farms have been turned into powders and oils that have become nutritional additives to pet and farm feeds. Thanks to a ruling last year by the European Food Safety Agency (EFSA) that deemed mealworms safe for human consumption, the company has also begun selling its powders for shakes, cereal bars, pasta, and even alt-meat burgers. In addition, the shed shells of the rapidly growing mealworms are collected and sold as beneficial organic fertilizers to farmers.

According to MealFlour, a project that promotes mealworm farming as a way to battle malnutrition in Guatemala, a serving of mealworm powder is 55% protein, contains all essential amino and fatty acids, and has more iron than sirloin beef. Compared to the production of milk, pork, chicken, and beef, mealworms are also more sustainable and require fewer resources and energy.

While its recent forays into human foodstuffs have garnered attention, Ÿnsect's focus presently remains on helping to feed sustainably the animals that feed the world. For instance, aquaculture, like salmon farming, is a resource-intensive operation that uses both land-based crops (soy) and massive amounts of wild-caught fish to create what's known as fishmeal. With food production projected to have to grow by more than 70% by 2050 to meet demand, the overfishing of oceans to feed aquaculture operations is not a feasible option. Studies, such as a recent trial by NOAA, have shown that supplementing or even replacing fishmeal with insect- and plant-based foods holds promise for eliminating the need for wild-caught sources. According to Hubert, there are other positives as well.

"They [salmon] were reaching the maturity stage faster and eating less so they were avoiding a large quantity of feed," he told Fast Company in 2020. "There was less mortality so the farmers get more fish eventually than before... This also explains why we have a carbon-negative balance, because we are avoiding so many quantities of inputs to feed fish to have the same quantities of fish."

Hubert added to Fast Company that Ÿnsect has contracts worth more than $100 million with fish feed producers. This past year, with the acquisition of U.S.-based mealworm producer Jord, it also began entering new markets, such as the rapidly growing U.S. backyard chicken feed market.

A Record-Breaking Vertical Farm

One look at the animated video of Ÿnsect’s new facility up above and you can see why it’s been touted as an automated marvel. Mealworms will be reared by robots in stacked tubs stretching several stories tall. Unlike other insect food alternatives such as flies or crickets, mealworms do not hop or fly, allowing the company to maximize the space available.

In an effort to make sure the creatures are ethically farmed, Hubert reached out to philosophers from the Sorbonne University to judge their welfare. As he told The Guardian, the students determined that the mealworms had "more in common with mushroom-growing and hothousing vegetables" than with livestock.

"They have no brain in the strict sense of the word," he said. "We know they have a reflex reaction and they communicate and build intelligent structures, but nobody has shown they feel anything. However, what is important is to respect them as living organisms, which we do."

In addition to the new farm in France, Ÿnsect plans to continue to scale its operations with additional facilities, including a major site in the U.S. The biggest hurdle ahead, however, says Hubert, is making insects a normal part of everyday diets.

"I believe that the big challenge is accepting insects as part of the human diet," he told Authority Magazine. "A large part of the world's population eats insects, but we must be able to prove its properties and its benefits for the environment in order to reach more and have more impact!"
