Salmon feed commonly includes fishmeal and fish oil to provide essential protein and omega-3 fatty acids, while plant-based alternatives like soybean meal and wheat flour are used to improve sustainability and reduce reliance on marine resources.

Additives such as probiotics, including lactic acid bacteria, are increasingly incorporated to enhance fish immunity and growth, reducing the need for antibiotics and minimizing disease outbreaks in aquaculture environments.

Minerals, vitamins, and amino acids are added to optimize nutrient absorption and support the overall health and productivity of farmed salmon.

Uncommon additives like glucan and Polydeoxyribonucleotide (PDRN) are explored for their potential to boost immunity and regenerative functions, though their broader applications in aquaculture remain limited.

Synthetic pigments such as astaxanthin are used to enhance the color of farmed salmon, mimicking the natural carotenoids found in wild salmon to appeal to consumer preferences.

Health concerns associated with feed additives include the accumulation of fat-soluble pollutants and contaminants like polychlorinated biphenyls (PCBs), which have been linked to cancer risks.

Antibiotics are frequently used to prevent diseases in high-density farming environments, but their overuse can lead to antibiotic resistance and environmental contamination.

Regulations governing salmon feed additives vary globally, with countries like Norway and Chile enforcing stringent standards to ensure sustainability and consumer safety.

Innovative alternatives such as insect-based proteins and mesopelagic fish are being researched to reduce reliance on traditional fishmeal and fish oil, addressing environmental concerns.

Consumers are advised to select farmed salmon products with certifications or traceability marks to ensure compliance with safety standards and minimize exposure to harmful additives.

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.”

Journalist Hsu Chien-yi / reporting from Taipei
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 and Polydeoxyribonucleotide (PDRN) are explored for their potential to boost immunity and regenerative functions, though their broader applications in aquaculture remain limited.

Synthetic pigments such as astaxanthin are used to enhance the color of farmed salmon, mimicking the natural carotenoids found in wild salmon to appeal to consumer preferences.

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.

Study: Eating Too Much ‘ Farm Salmon ’ May Cause Cancer
A medical study published on Monday warned that overeating salmon raised in farm ponds could lead to cancer.
The Daily Newspaper noted.

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."

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.

The Minister of Agriculture and Land Reclamation and Engineer Mustafa Sayyad, Deputy Minister of Agriculture for Livestock, Fisheries and Poultry, on Wednesday instructed the technical bodies of the Ministry of Agriculture to intensify control over the feed industry and circulation, stressing the need to continue the monitoring and inspection campaigns carried out by successive periodic committees formed by the livestock and poultry development sector and the Regional Center for Food and Feed to control the rhythm of the feed industry and circulation. Standards, controls and standard specifications, which must be registered at the Ministry of Agriculture, whether for animals, birds or fish.
Dr. Tarek Suleiman, head of the livestock and poultry development sector at the ministry, said that information has been received about the existence of a factory for the production of feed in Beheira governorate operating without a license from the Ministry of Agriculture and producing unregistered feed in the ministry.
He added that another committee raided a store for the sale of some feed additives in Giza governorate and advertises its products through social networking sites and found that the shop is not licensed and has quantities of 50 liters of feed additives not registered in the Ministry of Agriculture.
Suleiman explained that there are also other committees formed from the livestock and poultry development sector and the directorates of agriculture of Assiut, Marsa Matrouh and Nubaria to conduct operating experiments of feed processing lines to ensure the homogeneity of feed mixtures produced in 12 factories with sampling and analysis in the Regional Center for Food and Feed, which is an accredited reference laboratory.
The head of the Livestock Development Sector pointed out that 10 tons of feed additives that did not conform to the standard specifications on the basis of which they were imported, and 121 registrations of feed mixtures, concentrates and additives were registered between renewal and the first time, and 20 operating licenses were issued for feed factories between renewal and the first time last week.
He appealed to the Livestock and Poultry Development Sector and the Regional Center for Food and Feed to breeders and producers of livestock and poultry to ensure that the feed is manufactured in factories licensed to do so in the Ministry of Agriculture and that the feed mixtures are registered and approved by the Ministry, and to communicate with the Livestock and Poultry Development Sector on WhatsApp numbers (01558626681 - 01558626626682).

Content: Fish meat has heavy metals, eat not to eat? Doctor: small and medium-sized fish, farmed fish is the safest
Everyday Health - The Health You Can Do Everyday
The issue of heavy metal content in fish is indeed a food safety issue that deserves attention.
This is an advertisement, please continue reading.
Dr. Ooi Hean, a serious medical doctor, pointed out that the ocean is heavily polluted, and the heavy metals in the fish body are also accumulated and contaminated.
In general, the heavy metals commonly found in fish are arsenic, lead, cadmium, mercury, etc. These heavy metals may accumulate in the fish through the food chain, causing harm to human health.
Which fish has more heavy metals?
In general, fish that are at a higher level in the biological chain, such as large migratory fish or deep-sea fish, will increase the concentration of heavy metals in the fish with the bioaccumulation effect of feeding processes such as algae and small fish.
For example, sharks, swordfish, tuna, and oily fish are all species that are more likely to contain higher amounts of heavy metals.
The difference in heavy metal content between large and small fish
Because large fish are usually predatory, they eat many smaller fish, so they accumulate more heavy metals in their bodies.
Conversely, small fish are usually herbivorous or omnivorous and eat less heavy metals, so their heavy metal content is relatively low.
Therefore, in terms of consumption, it is recommended to choose small and medium-sized fish, and diversify the intake of different types of fish to reduce the risk.
Differences in Heavy Metals in Freshwater or Deep-Sea Fish
There is no absolute difference in the heavy metal content of freshwater or deep-sea fish, mainly depending on their growing environment and dietary habits.
In general, heavy metal pollution in the freshwater environment may come from industrial wastewater, agricultural water, mining and other human activities, while heavy metal pollution in the deep-sea environment may come from natural phenomena such as natural geology, volcanic eruptions, and submarine microbial metabolism.
Therefore, when selecting freshwater or deep-sea fish, pay attention to whether their origin and quality meet hygiene standards.
How to avoid excessive heavy metal content in fish?
Reduce the frequency of consumption of large deep-sea fish, or avoid consumption.
The Food and Drug Administration (FDA) has also revised the principle of "fish taking the index finger," subverting the deeply held beliefs of the general public, suggesting that people should avoid eating large deep-sea fish such as tuna and swordfish, so as not to accumulate the heavy metal "methylmercury" accumulated in the body.
Select qualified farmed fish.
Farmed fish are mainly affected by their water sources and feed.
Therefore, when choosing or operating a farm, make sure that the water source is clean and free of pollution, and regularly test the water quality.
In addition, when selecting or providing feed, ensure that its source is reliable and free of toxins and that it complies with relevant regulations.
Also, avoid using farmed fish that contain large amounts of antibiotics or other chemicals added.
For the monitoring of farmed fish, government agencies will have regular testing, in the natural state, those found in fish mercury, zinc, copper, nickel, lead and cadmium content monitoring, as the basis for environmental pollution assessment of farmed fish.
At present, these monitoring shows that the heavy metal content of farmed fish, most of them are lower than 1ppm, and it can be known that the heavy metal content from farmed fish is relatively small, and the public can eat it with peace of mind.
And British scientists agree that farmed fish are generally safer than wild fish because farmed feed, which has been washed or removed, has many toxic compounds or heavy metals.
Small and medium-sized fish, often changing species.
Experts recommend, for example, eating autumn cuttlefish today, bream tomorrow, and the day after tomorrow, to avoid long-term, high-frequency consumption of the same fish species, which causes a burden on health.
The Food and Drug Administration also reminded that for people who are fond of fish, it is recommended to eat all kinds of fish in a "variety of choices".
In his article, Huang encouraged people to eat fish because eating high-fat fish, including salmon, tuna, sardines and mackerel, can reduce the risk of cardiovascular disease because these marine fish contain two of the omega 3 (omega-3) fatty acids, EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid).
In addition to Omega3, fish has other beneficial nutrients, including selenium, a microelement that protects cells from damage and infection, iodine, which supports a healthy metabolism, and protein.
Therefore, eating fish can strengthen the brain and reduce the risk of the heart.
He reminded that people who want to fish can follow the Food and Drug Administration's advice to "choose a variety of fish", not only do they prefer to eat a large amount of specific fish, in order to achieve a balanced intake of nutrients provided by different fish, eat healthy and nutritious.
