Ocean acidification is a pressing issue that affects marine life, including cephalopods like cuttlefish, by reducing the availability of calcium carbonate, which is essential for building shells and skeletons.

The decrease in pH levels due to ocean acidification can dissolve calcium carbonate shells and skeletons, making it harder for creatures to build shells.

Ocean acidification occurs due to excessive carbon dioxide in the atmosphere, which is absorbed by the ocean, causing a decrease in pH levels.

Some fish can evolve rapidly to cope with ocean acidification, but there is limited information available on the specific responses of cuttlefish to changes in seawater pH.

Ocean acidification affects marine life physiology and behavior, including changes in genetic transcription and immune function, but the specific impacts on cuttlefish are not well understood.

Pteropods, which are related to cephalopods, are vulnerable to ocean acidification, particularly during winter, and a decrease in their populations can affect the food web and carbon cycle.

Ocean acidification can also impact the food web and ecosystem functions, such as water filtering and habitat creation, which are provided by invertebrates like cephalopods.

The combined effects of ocean acidification, warming, and pollution can lead to a decline in cephalopod populations and alter the structure of marine ecosystems.

Cephalopods, such as cuttlefish and squid, play important roles in marine ecosystems, and changes to their populations can have cascading effects on the entire ecosystem.

Ocean conservation efforts are necessary to sustainably use marine resources and to protect vulnerable species, such as cephalopods, from the impacts of ocean acidification and warming.

The ocean provides important ecosystem services and supports human well-being, and it is essential to take action to mitigate the effects of ocean acidification and warming on marine ecosystems.

Climate change, which includes ocean acidification and warming, disrupts environmental signals for habitat and food, and can alter ecosystem energy balance and structure.

Temperature shifts can change animal behavior and physiology, and can have significant impacts on the survival and reproduction of cephalopods and other marine species.

Ocean acidification is predicted to increase by 100-150% by the end of the century, which could have devastating effects on marine life, including cephalopods.

The lack of specific information on the impacts of ocean acidification on cuttlefish and other cephalopods highlights the need for further research and conservation efforts.

The United Nations' SDG 14.3 aims to minimize and address ocean acidification, and implementing this goal requires cross-cutting issue embedding and unique approaches by governments.

Place-based actions can aid in implementing SDG programs, and partnerships can provide synergies for joint SDG implementation.

Overall, ocean acidification is a significant threat to marine ecosystems, including cephalopods like cuttlefish, and urgent action is needed to mitigate its impacts.

Unfortunately, there is limited information available on the specific physiological and behavioral responses of cuttlefish to changes in seawater pH.

More research is needed to understand the effects of ocean acidification on cuttlefish and other cephalopods, and to develop effective conservation strategies.

The search results did not provide specific information on the impacts of ocean acidification on cuttlefish and other cephalopods, highlighting the need for further research.

Ocean acidification affects marine life due to high CO2 levels, and some fish evolve rapidly to cope with ocean acidification.

However, the specific impacts of ocean acidification on cuttlefish and other cephalopods are not well understood, and more research is needed to address this knowledge gap.

Ocean acidification is a complex issue that requires a comprehensive approach to mitigate its impacts on marine ecosystems, including cephalopods like cuttlefish.

The establishment of marine protected areas can conserve oceans effectively, and the designation of these areas requires public hearing and approval.

Kelp deployment on oyster farms can nullify ocean acidification, and kelp cultivation benefits bivalve growth and survival.

Ocean acidification affects odor tracking in reef fish and sharks, and climate change disrupts environmental signals for habitat and food.

Temperature changes disrupt environmental signals for habitat and food, leading to behavioral shifts in animals and ecosystems.

Ocean acidification is a consequence of global warming, and it increases water acidity by 26% since pre-industrial times.

A projected 100-150% acidity increase by the end of the century is expected to have significant effects on marine life.

Ocean acidification poses a threat to commercial aquaculture and food security, as it affects the growth and survival of many marine species.

Fish become suicidal due to climate change, and high acidity leads to fish species loss, with 30% of carbon dioxide emissions being absorbed by water.

Ocean warming and acidification affect Pacific cod's early life stages, with temperature being the dominant stressor.

Pacific cod growth is fastest at 10°C, but with high mortality, and ocean warming is a greater threat to Pacific cod than acidification.

Ocean acidification is a pressing issue that affects marine life, including cephalopods like cuttlefish, by reducing the availability of calcium carbonate, which is essential for building shells and skeletons.

Utilizing biogeochemical and genetic tools to understand and support clam populations in a changing ocean

Marine bivalves are at risk due to anthropogenic climate change. This poses a threat to commercial aquaculture, and the communities that depend on bivalves for food security. Ocean acidification, the lowering of seawater pH, is of particular concern for marine calcifiers, including bivalves. Ocean acidification occurs as carbon dioxide enters the atmosphere at a rate faster than natural geologic processes can buffer. It is energetically costly for marine calcifiers like clams, mussels, and oysters, to mineralize under acidic conditions, and low pH leads to the dissolution of calcium carbonate shells and skeletons. This problem warrants research on acidification adaptation strategies that will keep coastal populations healthy. Adding calcium carbonate shell hash to coastal sediments may mitigate negative effects of acidification on infaunal shellfish by altering the chemistry of pore fluids, thus providing a potential mitigation strategy for local populations, including species like the Pacific littleneck clam (Leukoma staminea).

Here, I present the first in-depth description of the shell mineralogy, microstructure, body size variability, and geochemical properties of modern L. staminea, a common eastern Pacific, shallow, infaunal bivalve. Additionally, I document the impact of ocean acidification on the shell growth and gene expression of L. staminea, and test whether adding shell hash to its infaunal environement can promote growth under acidified conditions. Juvenile clams were raised in four experimental conditions for 90 days: control seawater, acidified seawater, control seawater with shell hash, and acidified seawater with shell hash. Clam shell weight, soft tissue weight, and new shell growth were measured. The presence of shell hash increased the pH, alkalinity and aragonite saturation state of pore fluids across all treatments, and increased shell growth on average, although growth metrics were variable across and within treatments. Lastly, RNA-sequencing revealed the impacts of experimental acidification on juvenile clam gene expression. Clams grown in the presence of shell hash had gene expression profiles more similar to those grown in control (non-acidified) conditions. In all, this research suggests that adding shell hash to coastal sediments alters the chemistry of pore fluids and buffers against acidic conditions that deleteriously affects clam mineralization.

In addition to causing climate warming, global emissions of large amounts of carbon dioxide will also cause sea water to become acidic, and marine life may be affected.
The study found that volcanic infiltration of high CO2 partial pressure, that is, high concentrations of CO2 dissolved in water, changes in the genetic transcription of fish, predict the response of wild fish to the continuous acidification of the marine environment.
The results show that some fish with faster rates of evolution may be more flexible in coping with ocean acidification, maintaining population size and diversity. One species of fish may be able to acidify the marine environment with its rapid evolution of gene molecular transcription regulation, but the population size and diversity of fish with slower rates of evolution are difficult to maintain in acidified environments.
As carbon dioxide emissions from human activities increase year by year, and the CO2 absorbed by the ocean continues to rise, causing the pH of seawater to decline and become acidic, scientists expect “ocean acidification ” on the surface of the world ’ s oceans, which may affect the physiology, growth and survival of some fish, and change some key behaviors that affect survival chances.
A team led by Celia SCHUNTER from the Faculty of Biosciences of the University of Hong Kong and the Swire Institute of Marine Science, along with foreign researchers, travelled to Papua New Guinea, the Pacific island nation, to extract the brains of six species of coral fish, including five species of finch and one species of celestial bream, from a carbon dioxide spill at the bottom of a volcano and about 500 m nearby coral reef. The organization conducts gene transcription group sequencing to understand the changes in fish gene transcription in the ocean acidification environment.
The results show that high CO2 partial pressure can cause transcription changes in genes related to circadian clock and immune function in several species, demonstrating that fish function is important in coping with acidifying environments, and that the core genes of circadian rhythms determine the 24-hour cycle of most species.
Immune-related regulation has been found in many species of fish in acidified environments, so regulation of the immune response may also be an important response to acidification, especially in nocturnal fish, which exhibit a greater proportion of immune regulation and are modulated in the opposite direction to diurnal fish.
In contrast to the fish body ’ s ability to regulate the pH value of the cells, the researchers found that the brain of the spinosus is used to maintain a large number of changes in potassium, sodium, chlorine and calcium ions that transmit signals in the carbon dioxide ooze. Corresponding changes are needed to cope with the acidification environment, but differences in the expression of related genes disappear when stress is reduced, and genes return to normal levels of expression.
Further research by the team found that this finch has evolved significantly faster than other fish over the past 15 million years, potentially giving it greater potential to adapt to environmental changes.
It is speculated that this species may have evolved molecular mechanisms to cope with future ocean acidification.

Which marine organism is vulnerable to increased levels of ocean acidification?

Pteropods, which are related to cephalopods, are vulnerable to ocean acidification, particularly during winter, and a decrease in their populations can affect the food web and carbon cycle.

Title:

Content: Newswise — When carbon dioxide (CO2) enters the oceans, it can make the water more acidic, which is called ocean acidification. This can make it harder for some ocean creatures, like pteropods, to build and keep their shells. Pteropods are important for the ocean environment.

Pteropods are small sea creatures, including shelled sea butterflies. Not much is known about them because of their size, and they don't survive well in captivity. A team of marine scientists studied the life cycles, abundance, and seasonal changes of shelled sea butterflies in the north-east Scotia Sea, where climate change is happening quickly.

Dr Clara Manno, a researcher at the British Antarctic Survey and the corresponding author of the study published in Frontiers in Marine Science, said that the decrease in pteropod populations in the Antarctic Ocean could have significant consequences for the food web and carbon cycle. She also said that understanding the life cycle of this important organism could help to predict the impact of ocean acidification on the Antarctic ecosystem.

Population stability essential for species survival

To study the life cycle, abundance, and seasonal variability of shelled sea butterflies in the north-east Scotia Sea, a team of marine scientists collected sea butterflies in a sediment trap, a sampling device that was anchored at a depth of 400 meters. Since observing the entire life cycle of sea butterflies in a laboratory setting is impossible, the researchers had to gather information about their spawning, growth rate, and population structure. They were able to reconstruct the sea butterflies' life cycle for a year using the samples from the sediment trap.

The scientists found that the two most commonly collected species, Limacina rangii and Limacina retroversa, have different life cycles and therefore have different levels of vulnerability to changes in the ocean. During the winter months, L. rangii, which is a polar species, can be found as both adults and juveniles, while L. retroversa, a subpolar species, is only found as adults during the winter.

Sea butterflies that exist during the coldest season are more vulnerable to increased levels of ocean acidification. This is because ocean water is more acidic during this season than during other times of the year due to cooler temperatures that increase CO2 dissolution in the ocean. The researchers explained that the life stages of sea butterflies during this time are more exposed and vulnerable to the effects of ocean acidification.

L. rangii has a survival advantage over L. retroversa because both adults and juveniles coexist during winter, which reduces the risk of population instability if one cohort is vulnerable. In contrast, if one cohort is removed from L. retroversa, the entire population could be at risk.

Prolonged exposure is a survival challenge

The researchers pointed out that although the two species are affected differently, both are likely to suffer harm if they are exposed to unfavorable conditions for prolonged periods.

The scientists cautioned that the intensifying and prolonged events of ocean acidification overlap with the spring spawning period, posing a threat to the most vulnerable life stage, the larvae. This could endanger the future populations of sea butterflies.

The research team plans to further study the sea butterflies in the Scotia Sea to see how they would be affected by the increase in the intensity and duration of ocean acidification events. They will study multiyear sediment trap samples to identify potential changes in the life cycle that may occur due to environmental changes. Dr Jessie Gardner of the British Antarctic Survey, lead author of the study, said this will be the next step in their research.

International scientists warn of the serious impact of noise pollution on marine invertebrates

An international scientific study, led by the UPC's Laboratory of Applied Bioacoustics (LAB), shows that noise from human operations at sea damages marine invertebrates and ocean ecosystems. Published in Frontiers in Marine Science, the work points out that noise pollution at sea can even cause death in some marine species.

In recent decades, scientists have studied the sensitivity to noise of marine mammals—especially cetaceans and pinnipeds—and fish because they are known to possess hearing organs. Recent studies have revealed that a wide variety of are also sensitive to sound, particularly via sensory organs whose function is to allow maintaining equilibrium in the water column and to sense gravity. Not only do represent the largest proportion of marine biomass and are indicators of ocean health, but many species also have important socio-economic values.

A team of scientists, made up of researchers from the Laboratory of Applied Bioacoustics (LAB) from the Universitat Politècnica de Catalunya—BarcelonaTech (UPC) and other universities and research centers in Australia, Spain, the United States, France, Japan, Italy, New Zealand and the United Kingdom, have reviewed hundreds of studies on the impact of noise on marine invertebrates such as crabs, molluscs, squids, prawns and worms. They concluded that anthropogenic noise—noise from human operations—is harming these species in many ways, from cellular to ecosystem level.

"Many people are surprised to discover that invertebrates can even perceive sound, but sound is, in fact, essential to their survival," explains Marta Solé, UPC's LAB researcher linked to the Polytechnic School of Engineering of Vilanova i la Geltrú (EPSEVG). "Light does not travel easily underwater, but sound does, and invertebrates use sound for their vital activities (interspecific communication, predator detection, reproduction, etc.). Human operations, especially shipping, are changing the ocean soundscape very rapidly, and this study brings together the latest evidence on these impacts." Shipping is the main source of marine noise, but there are many others—drilling, dredging, sonar, etc.—and this affects the natural balance of the oceans.

Multiple impacts

Titled "Marine invertebrates and noise," the paper was published in the journal Frontiers in Marine Science. It warns of the multiple impacts of on invertebrates, such as delayed hatching and development of eggs, and significantly increased larvae abnormality and in crustaceans, bivalves (mussels and oysters), gastropods (snails) and cephalopods (cuttlefish and squids).

Low-frequency sounds, such as those from underwater explosions, can cause injury and even death in blue crabs. Long-term exposure of these species to noise also affects their behavior. Ship noise limits shore crabs' ability to change color for camouflage, according to the team of researchers.

After sound exposure, Mediterranean common cuttlefish showed changes in the protein content, mainly structure- and stress-related proteins. The authors have also reviewed studies demonstrating physiological changes in some species, such as a significant reduction in the rate of growth and reproduction, an increase in the level of aggressiveness and the mortality rate, and a reduction in feed intake.

Recent studies have revealed that a wide range of invertebrates are sensitive to sounds, especially via statocysts—analogous to the vertebrate inner ear—whose original function is to allow maintaining equilibrium in the water column and to sense gravity.

How do invertebrates produce and detect sound?

Sound travels about five times faster in water (ca. 1,500 m/s) than in air (ca. 340 m/s) because the density of water is greater, and also attenuates less over the same distance. Invertebrates detect underwater sound through three types of sensory systems: ciliated receptors on the , statocysts and chordotonal organs, linked to the joints of antennae or legs in crustaceans.

They can also produce sounds: from "coughing" in scallops to stridulation, in which lobsters, crayfish, prawns and crabs rub together certain body parts—similar to bowing a violin—and make sounds that may scare off predators. The study presents all these forms of sound production and perception specific to invertebrates, and the techniques used for their analysis.

Effects of noise on ecosystems

By changing the behavior and health of predators and prey in complex food webs, noise can thus affect entire ecosystems. Invertebrates provide major ecosystem functions, such as water filtering, habitat creation, organic matter processing, carbon transfer through food webs and nutrient recycling. Therefore, researchers see it as urgent to continue research in this area to mitigate the impacts.

"Our study highlights that these animals exist in a rich underwater soundscape," explains Dr. Sophie Nedelec from the University of Exeter. "We need to learn more about the impacts of noise pollution on these animals and ecosystems. Given that noise can affect invertebrates from cellular to ecosystem level, we need to bring together interdisciplinary expertise to gain a holistic view of the problem. Considering the many anthropogenic pressures, including and fishing, we must do everything possible to limit underwater noise."

The study summarizes the current scientific knowledge on invertebrate bioacoustics ( production, reception, sensitivity) and on how marine invertebrates are affected by anthropogenic noises. It also identifies gaps in scientific knowledge on the tolerance of marine ecosystems, concluding that more research is needed.

« Research » conducted a study on the impact of « acidification » on shrimp
The Kuwait Institute for Scientific Research (KISR), in cooperation with the Kuwait Foundation for the Advancement of Sciences (KFAS) and the International Atomic Energy Agency (IAEA), completed a study project to investigate the impact of ocean acidification and ocean surface warming on the growth and abundance of local shrimp.
In turn, the head of the project, researcher Lamia Muslim at the Center for Environmental and Life Sciences Research at the Institute, said that there are many animals that contain in their skeleton or shell calcium carbonate, and changes in the pH of water can negatively affect these organisms, especially in the early stages of their life. The sea and some phytoplankton species, but that does not mean that this is a positive thing because the increased growth of these organisms can disrupt the food chain, biodiversity and ecosystem mechanisms and construction.
She added that the presence of large amounts of carbon dioxide in the atmosphere leads to the occurrence of global warming and the rise of the surface of the oceans by between one and three degrees Celsius, and the rise of the water level to an amount ranging from 0.18 to 0.79 meters, which in turn leads to acidification and warming of the surface of the oceans, and therefore to change the chemistry of the ocean and threaten marine ecosystems.
She pointed out that the shrimp mothers were collected from Kuwaiti territorial waters during the breeding season to obtain eggs and shrimp larvae in sufficient numbers to conduct experiments on all stages of shrimp age, as the study experiments were conducted in the laboratories of the Institute in a controlled system simulating the expected climate changes in the future.
The results of the study confirmed that the warming of the surface of the oceans could have a greater impact than ocean acidification on the early life stages of shrimp larvae, as shrimp larvae exposed to high temperatures showed accelerated growth rates to reach the sizes of older shrimp, but with lower survival rates, it is very likely that lower survival and growth rates under future climate scenarios may lead to the emergence of smaller shrimp larvae. These larvae will undergo multiple molting processes over their life cycle making them vulnerable; furthermore, the study results suggest additional effects of combined exposure to ocean surface warming and acidification on egg-hatching success, survival, and shrimp larval development.
Al-Musallam said: “The study is fully consistent across the entire life cycle of the M Nair shrimp, where high mortality of larvae at low pH and high water temperature indicates a possible collapse of this species of crustacean under conditions of increased ocean acidification and future warming of the ocean surface, which also leads to a significant reduction in shrimp stocks in the Arabian Gulf due to overfishing or reduced larval growth due to climate change. ”
For his part, dr.
Dr. Saifuddin Iqbaluddin, from the Center for Environmental and Life Sciences Research, said experts regularly measure water temperature and pH levels and look at how marine life might respond to these changes in the coming decades.

Scientists know how octopuses and cuttlefish can disguise themselves as colors of the environment or soil to hide from predators.
But the specialists of the Department of Physics and Biology of the Okinawa Institute of Science and Technology learned about this ability in squid in early April, who conducted a number of experiments.
“When the oval squid were in the part of the aquarium with clean water, they were light in color, but when they got into the part with algae, they became darker.
Scientists stressed that in addition to opportunities to study the new abilities of squid, the study reveals yet unknown to science adaptations for their survival, ” — reported on the website of the Institute.
According to Dr. Ryuta Nakajima, a visiting researcher, squid usually hover in the open ocean, but scientists were interested in figuring out what happens when they approach a coral reef or if they are chased by a predator on the ocean floor.
"If the ability to mimic is important for squid when encountering a predator, it indicates that increasing or decreasing squid populations is dependent on coral reef health much more than we thought," said Dr. Nakajima.
The ability of squid to change color was discovered by chance.
At the Institute ’ s Marine Science Station, researchers cleaned a tank for marine animals to remove the overgrown algae.
They noticed how the squid changed color while in purified water or hovering over the algae.
A control experiment proved that squid really can change color depending on their environment.
Earlier, researchers at Harvard University said that the increase in the temperature of the oceans increases the concentration of mercury in fish and shellfish.

How climate change is changing the brain and behavior of animals
Due to global warming caused by human activities, the habitat on Earth is changing more and more.
This leads to an increase in temperature, rapid changes in rainfall and seasons, and ocean acidification.
How do animals deal with this?
Population Connection
In the response of animals to climate change, their nervous system plays a key role.
Due to its basic functions (sense detection, mental processing of information, behavior control), animals are oriented in the environment, can survive and reproduce.
Because of temperature changes, the energy balance of ecosystems is changing.
It is likely that this will also affect their basic senses, from sight and taste to smell and touch.
Mammals partially perceive temperature with the help of special receptor proteins in their nervous system.
These proteins respond to heat and cold, helping to distinguish between moderate and extreme temperatures.
Due to these proteins, animals can also look for a suitable habitat.
GETTY
Climate change disrupts the environmental signals that animals rely on when choosing their habitat, finding food, and partners.
Temperature shifts, for example, change where and when mosquitoes look for hosts, how they transmit diseases.
In addition, seasonal changes in daylight can lead to disconnection between daylight hours and flowering and fruiting of plants, changes in hibernation and migration of animals, when daylight hours no longer predict the availability of resources.
Due to the increase in temperature, the development and functioning of the brain of animals can be
This could also potentially affect their ability to adapt effectively to new habitats.
Scientists have found out how extreme temperatures can change individual neurons at the genetic and structural levels, the structure of the brain as a whole.
For example, in the marine environment, ocean acidification can affect the tracking of odors in reef fish and sharks.
Because of climate change, animals can change their habitat.
These behavioral shifts will change the structure of ecosystems around the world with complex and unpredictable consequences.
It is known that the brain of animals is very flexible and can significantly change even in adults.
However, studies have revealed a strong influence of the environment on the evolution of the brain.
Most likely, the new climatic regimes will eventually form nervous systems, causing them to develop.

What factors lead to damage of coral reefs?

Temperature shifts can change animal behavior and physiology, and can have significant impacts on the survival and reproduction of cephalopods and other marine species.

Ocean acidification is predicted to increase by 100-150% by the end of the century, which could have devastating effects on marine life, including cephalopods.

EVENT AGENDA

The world is waking up to the threat that ocean acidification (OA) poses to marine ecosystems and to the coastal economies that depend on them. OA is a rise in the acidity of seawater caused by an excess of anthropogenic carbon dioxide emissions (CO2) being absorbed by the ocean.

 To implement SDG 14.3 “to minimize and address ocean acidification”, OA must become a cross cutting issue embedded across climate, ocean, and marine policies.

 Advancing national OA actions will inform better decision making for achieving domestic mitigation, adaptation, and resilience goals.

 Come learn about the National OA Action Planning Leadership Circle, where invited governments are finding their unique approach to OA Actions across 2024-2025, leading to national implementation of UN SDG 14.3 “to minimize and address OA” by the 3rd UN Ocean Conference in 2025.

The Sustainable Development Goals (SDGs) adopted by the United Nations in 2015 constitute a set of 17 global goals established as a blueprint for achieving a more sustainable and equitable world for humanity. As part of the SDGs, target 14.3 is focuses on minimizing and addressing the impacts of Ocean Acidification (OA). We argue that moving forward in meeting the targets related to pH levels in the coastal ocean can be facilitated through accounting for various drivers of pH change, which are associated with advancing a suite of SDG goals. Addressing ‘coastal acidification’ via a suite of linked SDGs may help avoid inaction through connecting global phenomena with local impacts and drivers. This in turn can provide opportunities for designing novel place-based actions or partnerships that can aid and provide synergies for the joint implementation of programs and policies that tackle a suite of SDGs and the specific targets related to coastal ocean pH.

Florida Sea Contaminated Fish Floods Detect an Average of Seven Drug Reactions
A study of fish off the coast of Florida tested positive for a large number of human drugs, reflecting an underlying concern about pollution of marine ecology by human waste water.
Researchers at Florida International University (FIU) and BTT have been studying the Biscayne Bay and Florida Keys populations since 2018.
The researchers collected blood and tissue samples from 93 fish and catfish, and found that each sample contained an average of seven human drug components, including antidepressants, blood pressure lowering drugs, prostate therapy drugs, antibiotics, and pain killers.
One fish even had as many as 17 drug ingredients in its tissues, and drug reactions were also detected in its prey such as crabs and shrimp.
Medicines can affect fish life, including their feeding habits, social behavior, and migratory behavior, threatening the already shrinking population of the northern cuttlefish.
Jennifer Rehaga, a coastal and fish ecology scholar at Florida International University, said: “These findings tell us that this is a terrible threat to fisheries and highlight the urgent need to address the long-standing issue of wastewater infrastructure. ”
The study also noted that nearly 5 billion prescriptions are issued in the United States each year, with the clinical research institute IQVIA reporting that 6.3 billion prescriptions were issued in 2020.
Despite this, there is still a lack of environmental regulations for drug disposal; drugs can be discharged through urine into fresh water, such as lakes, rivers, etc., because the water treatment system cannot fully filter the drug.

When MEPC was established in 2018, it set out three major visions: clean oceans, healthy habitats and sustainable resources.
However, if it is to be realized, it must be based on laws and regulations, and MEPC can administer according to law.
Among them, the Amendment Ordinance to the Marine Pollution Prevention and Control Law, which is required to "Clean the Ocean", was passed on May 12, 2023.
“Healthy habitats ” require the adoption of a special law on marine protected areas, that is, the Marine Conservation Law.
Sustainable resources are divided into two parts: economic and non-economic aquatic products, which are handled by the Fisheries Department and the Marine Conservation Department respectively.
The former is based on the Fisheries Act of the Fisheries Department, but the latter, the Marine Conservation Department currently only has the Wildlife Conservation Act to protect a very small number of protected animals, its effectiveness is limited, but also need to set up marine protection areas, the habitat or ecosystem of all species together to protect success.
Establishment of Marine Protected Areas
The most effective, simple and economical way to conserve the oceans
It is the easiest, most economical and most effective way to conserve the oceans.
As a result, the world is now pushing hard.
The Aichi Goals adopted by the Conference of the Parties to the Convention on Biological Diversity in 2010 and the United Nations Sustainable Development Goals in 2015 set a target of 10% of the world ’ s oceans to be included in protected areas by the end of 2020.
Although this goal has not been fully achieved, the Kumon target for 2030, adopted by the Conference of the Parties at the end of 2012, has increased the target to 30%, which is known as the 30 X 30 target.
However, the "healthy habitat" and "sustainable resources" of the three major visions of the MEPC still lack the most important "Marine Conservation Law" as the basis for governance, and it is even more difficult to integrate with the international community.
Unfortunately, when the public hearing was held on March 25, a number of representatives still spoke, arguing that the legislative process and public communication were poor, and would affect the rights and interests of fishermen and indigenous people in fishing, and that it was necessary to hold five public hearings in a month.
What is more, the designation of a new marine sanctuary requires the approval of a local public hearing and a deliberation committee with representatives of fishermen and indigenous people, and it is not a blank cheque to the IOC to designate it arbitrarily.
Of course, there is nothing wrong with holding more public hearings.
However, it is worrying that some of the statements heard at the public hearing were not correct and ran counter to international trends and trends in marine conservation and fisheries sustainability, and it is necessary to add to this at this critical time.
Some friends are worried that the designation of marine protected areas will affect the fishing of fishermen and indigenous people.
As everyone knows, the delineation and effective management of marine protected areas can allow the fish to have a safe home, not to be wiped out by a net, and then through the spillover effect, the fishermen can sustainably fish, and the traditional fishing and hunting culture of the indigenous people will not disappear because there is no fish to catch.
In addition, marine protected areas can assist in the transformation of fishing villages, and the sustainable use of marine living resources through the development of ecological tourism.
In addition, marine protected areas have an even more important benefit, which is that they can mitigate and adapt to the impacts of climate change.
Because marine protected areas have the carbon sink function of "blue carbon" and "fish carbon", it can help reduce the problems of sea water warming, coral bleaching, fishery depletion and ocean acidification.
As a result, marine protected areas have been recognized as the “best natural solution ” or“ nature-based solution ” to mitigate and adapt to the impacts of climate change on biodiversity.
Last November, I took the opportunity of giving a lecture at Ryukyu University in Japan to dive four times in Okinawa. The beauty of the local seabed is exactly what I saw on the seabed of the Taiwan outlying islands 30 or 40 years ago.
I can ’ t help but wonder why Okinawa, which is on the Kuroshio Current with Taiwan, can do it, but Taiwan can ’ t? So the passage of the Marine Conservation Law is not for our generation, but for the next generation, so that they will have fish to eat, fish to enjoy, and fish to do research materials.
This is truly sustainable.
Otherwise, when the next generation reviews and criticizes us, it is easy to find out from the report of the public hearing of the Legislative Yuan who is the historical sinner who has let the ocean resources dry up.

Kelp deployment on oyster farms can nullify ocean acidification, and kelp cultivation benefits bivalve growth and survival.

Title:

Content: Newswise — STONY BROOK, NY, May 25, 2022 – While kelp is known as a nutritious food item for sea creatures and humans alike, harvesting kelp may be a new way to help keep bivalves such as clams and oysters – a more common food source and marine industry staple – healthy and more abundant. A new study led by Christopher Gobler, PhD, and a team of scientists at the Stony Brook University School of Marine and Atmospheric Sciences (SoMAS) shows that the presence of kelp significantly reduces ocean acidification, a result of climate change.

Published in Frontiers in Marine Science, the study also demonstrated that the deployment of kelp on an oyster farm nullifies ocean acidification and therefore protects bivalves against acidification. The process may also have additional ecosystem and aquaculture benefits, including the sequestration and extraction of carbon and nitrogen, and protection against harmful algae blooms.

For shellfish, one of the most serious climate change-related threats is ocean acidification. Carbon dioxide or CO2 levels in Earth’s atmosphere continue to rise, infiltrating oceans where it causes chemical reactions that lower pH and cause ocean acidification. For the past two decades, one of the most robust conclusions of ocean climate change research has been that increasing levels of CO2 in surface waters threaten shellfish that rely on higher pH waters to grow and survive. This threat is particularly acute in coastal zones where additional sources of acidity can further reduce pH and slow shell formation in shellfish, especially bivalves. And while many wild populations of bivalves have collapsed, a burgeoning wave of aquaculture in the U.S. and around the World has caused the global production of seafood via aquaculture to grow and now exceed wild capture.

“Despite this wave of aquaculture, the intensification of ocean acidification now threatens bivalve aquaculture and has necessitated a solution,” explains Professor Gobler, the Endowed Chair of Coastal Ecology and Conservation at SoMAS.  “We believe our work is foundational to a solution.”

In the study, titled “Kelp (Saccharina latissima) Mitigates Coastal Ocean Acidification and Increases the Growth of North Atlantic Bivalves in Lab Experiments and on an Oyster Farm,” Professor Gobler and colleagues conducted six experiments to assess the effects of elevated CO2 and presence of kelp (S. latissima) on the growth rates of three different species of bivalves: (Eastern oysters (Crassostrea virginica), blue mussels (Mytilus edulis), and hard clams / Northern quahogs (Mercenaria mercenaria).

In each of the experiments, acidification was significantly reduced with the cultivation of kelp. They furthered the research with the ultimate test – a field experiment at the Great Gun oyster farm in Moriches Bay, New York.

They found that during a one-month deployment, oysters that were surrounded by kelp enjoyed higher pH water and grew significantly faster than individual shellfish located further away where the pH of the water was significantly lower.

Professor Gobler and colleagues emphasize that these findings have powerful implications for oyster farming in coastal zones.

“We have been witnessing coastal ocean acidification for years and have documented its ability to slow the growth, and even kill off, shellfish. We began growing kelp on oyster farms to simply expand aquaculture, regionally. After seeing its ability to rapidly take up CO2 and improve low pH conditions, we knew it had the potential to benefit shellfish experiencing acidification. And while showing that in the lab was exciting, being able to improve the growth of oysters on an oyster farm experiencing coastal acidification proves this approach can have very broad applications,” explains Professor Gobler.

Overall, the research clearly shows, according to the authors, that “the cultivation of kelp constitutes an environmentally friendly means of protecting shellfisheries against present and future ocean acidification and other coastal stressors.”

Building on the work, helping the oyster farms

“We’ve helped grow kelp on 10 oyster farms across New York since 2018 and more and more aquaculturists have been hoping to incorporate kelp into their farms,” says Mike Doall, Associate Director of Shellfish Restoration and Aquaculture at Stony Brook University. “In addition to providing crop diversification and additive revenue streams, the ability of kelp to fight ocean acidification gives these oyster farmers one more reason to add kelp as a second crop.”

The recent study builds on other research by the same SoMAS group, which published a study in Harmful Algae in 2021. That study demonstrated that kelp has the ability to deter the intensity of harmful algal blooms, another environmental threat to shellfish aquaculture.

Such scenarios with kelp appear to create a win-win scenario for oyster farmers like Paul McCormick, owner of the Great Gun oyster farm where the current study was performed.

“Kelp looks to be the perfect complement to oysters on my farm,” says McCormick. “It grows during winter and spring, when the oysters need less attention, and there is lots of interest in kelp from restaurants. If it is offering protection to my oysters against poor water quality, well that’s another good reason to add it to my farm.”

A recent scientific study revealed serious risks to fish stocks in various seas and oceans around the world, as a result of climate changes, where greenhouse gas emissions lead to increased acidity of water, prompting fish to commit suicide, attracted to large predatory fish.
The study, conducted by a team of researchers at James Cook University in Australia, aims to assess the impact of greenhouse gases that cause climate change on the coral reef area off the coast of Papua New Guinea, in the southwest Pacific Ocean, where the region is witnessing volcanic activity.
The results of the study showed that the high rate of acidity in the ocean waters, as a result of the escalation of carbon dioxide from repeated volcanic activities below the depths, leads to the loss of species of fish, on which fishing activity depends, their ability to survive, making them easy prey for other predatory species.
The study, published on the site « Nature Climate Change », that fish in general can smell the smell of large predatory species, which helps them to get off track, but surprise that in the area under study, it turns out that fish are attracted to the smell of predatory species, making them easy prey.
Lead researcher Professor Philippe Mendai said the acidity effect of the water has also been shown to cause fish to wander aimlessly into the water and go to areas far from where they live, putting them at risk, where they are more likely to be attacked by predatory fish.
The main author of the study pointed out that these threats to fish are not limited to volcanic activities, noting that about 30% of the carbon dioxide emissions in the atmosphere are absorbed by water bodies, leading to increased acidity of the seas and oceans.
The researchers also warned that the acidity levels in the coral reef area in question have reached very high levels and are expected to spread to other areas, and may include the entire Pacific Ocean by the end of this century, as the phenomenon of climate change worsens.
The study concluded that fish that live for long periods of life exposed to high levels of carbon dioxide, could not cope with the changes caused by high acidity in the water, as a result of exposure to high levels of carbon emissions permanently.

Ocean warming and acidification affect Pacific cod's early life stages, with temperature being the dominant stressor.

Study explores combined impacts of ocean warming and acidification on pacific cod

As the climate changes, the ocean is simultaneously warming and acidifying. Both have been shown to adversely affect the vulnerable early life stages of Pacific cod. But until now, the interplay of these two environmental stressors was unknown.

new NOAA Fisheries study takes a look into the future by replicating predicted Alaska ocean conditions in the laboratory. The study is the first to look at the interactive effects of ocean warming and acidification on Pacific cod. Researchers evaluated the growth and survival of eggs and larvae at combinations of temperature and acidity representing current and future ocean environments. The findings can help improve predictions to ensure climate-ready Alaska fisheries and communities in the future.

Alaska Fish Face Multiple Climate-Driven Stressors

Ocean warming and acidification are escalating faster in Alaska and other high latitude regions than anywhere else on the planet. Alaska produces more than half of the nation’s wild-caught seafood. Local communities depend on the ecosystem for their livelihoods. Understanding how climate-driven stressors will affect these valuable resources is critical to ensuring resilient Alaska communities and a strong blue economy in the future.

Because fish are cold-blooded, temperature profoundly affects their growth and behavior. The effects of acidification are more nuanced. Fish can buffer acidity in the bloodstream but at an energetic cost.

Very young fish—eggs and larvae—tend to be the most sensitive stages of the fish life cycle to both warming and acidification. Unlike adult fish that can move to cooler waters, these tiny creatures are incapable of migrating to more favorable conditions. Subtle differences in their growth and condition can make a big difference to the number of young fish that make it to the adult population.

Laboratory set up for ocean acidification and ocean warming experiments with early stages of Pacific cod. Large tanks in the background provide chilled and ambient seawater that are mixed to temperature. Small round tanks house eggs and larvae at different temperatures and acidification levels. Acidification is controlled by bubbling carbon dioxide into the seawater: more carbon dioxide causes higher acidity (lower pH). (Image credit: NOAA Fisheries/Emily Slesinger)

Pacific cod is an important subsistence food, a key species in the food web, and the second-largest commercial groundfish catch in Alaska. Understanding how warming and acidification together may affect this ecologically, culturally, and commercially valuable species is key to predicting future climate impacts.

“Knowing how individual species will respond to multiple climate stressors helps us put together this puzzle to figure out what species are more vulnerable than others,” Emily Slesinger said. “And that will help guide ecosystem-based fisheries management to ensure their sustainability.”

Partnerships and Unique Laboratory Capabilities Expand Possibilities for Studying Alaska Species

Finding answers posed some hurdles. “It’s really challenging to study these fish that are found in remote and cold environments,” Slesinger said.

They met those challenges through partnerships and a specially equipped laboratory facility.

Fishermen played a key role. To obtain eggs and larvae for experiments, they first needed live adults, ready to spawn. Commercial fishermen used baited fishing pots to catch adults off Kodiak Island during the spawning season.

Fertilized eggs were shipped to the NOAA Fisheries Alaska Fisheries Science Center Laboratory in Newport, Oregon. The eggs and larvae were reared at six combinations of temperature (3°C, 6°C, 10°C) and acidification (ambient and high acidity). Scientists measured their hatch success, growth, nutritional condition, and mortality throughout the nine-week experiment.

“The Newport lab is very special,” Slesinger said. “What is most unique is our seawater system that can chill water to Arctic temperatures. The lab has the capacity to house many fish at all life stages and the expertise to keep them thriving. And it has the facilities to run these complicated experiments on the younger life stages.”

Experiments Reveal a Dominant Stressor

The study found that overall, Pacific cod’s early life stages were more sensitive to warming than to acidification:

  • Temperature affected all measured traits: growth, condition, and mortality
  • Mortality of both eggs and larvae was highest at the warmest temperature
  • 6°C was the optimal temperature for hatching, condition, and survival
  • At the warmest temperature (10°C), Pacific cod grew the fastest but were in poor condition with high mortality rates
  • At the coldest temperature (3°C), mortality rates were lower, but both growth and condition were also low
  • Acidification effects were more modest and inconsistent
  • The single instance of a negative effect of acidification was at the optimal 6°C temperature

“We’re seeing that either temperature or acidification drove the response—they were not additive. At optimal temperatures, Pacific cod may be impaired by acidification. At the warm temperature, they were overwhelmingly negatively impacted, but there was pretty much no effect of acidification,” Slesinger said. “Our findings suggest that temperature is the dominant stressor and ocean warming is likely the greater threat.”

The research highlights the complexity of species- and stage-specific responses to multiple climatic stressors and the importance of understanding them.

“This work is exciting because we are able to provide information about these fish that can be useful for future management. It is really important to me that my research can be directly helpful to societies, economies, and communities,” Slesinger said. “This research contributes to our common goal of ensuring productive, sustainable fishing into the future.”

Syrian traditional glassblowing dates back over 2000 years to the Phoenicians.

The craft has been passed down through generations, using recycled glass and high-temperature ovens to create products like hookah bottles, vases, and decorated cups.

Glassblowing is a plastic art, valued for its creativity and aesthetics.

The craft is a vital part of Syria's intangible heritage, preserving national identity and authenticity.

Syria is home to one of the oldest and richest heritages, including traditional glassblowing.

UNESCO listed Syrian traditional glassblowing as Intangible Cultural Heritage in Need of Urgent Safeguarding.

Globalization threatens Syrian heritage, including traditional crafts like glassblowing, prompting UNESCO to list it as in need of urgent safeguarding.

The number of traditional Syrian glassblowers is unknown, and the craft is at risk due to war, migration, and lack of support.

War and migration have led to a 50% decline in traditional crafts in Latakia province.

High costs and unequal competition have contributed to the decline of handicrafts like glassblowing.

The Syrian government and artisans are collaborating to preserve ancient glassblowing heritage through training, exhibitions, and financial support.

Preserving traditional glassblowing is essential for maintaining Syria's cultural heritage and identity.

The Syrian Ministry of Culture and General Union of Craftsmen support artisans through exhibitions, seminars, and resources, helping preserve traditional crafts like glassblowing.

UNESCO recognized Syrian glassblowing in December 2023.

Content: Art of glassblowing returns again in Aleppo countryside liberated from terrorism

The town of Urem Al-Kubra in Aleppo province in northern Syria has historically been famous for its skilled glassblowing craftsmen. The war considerably affected this traditional craft inherited from our ancestors, but after the liberation of the city from terrorism, some artisans have brought it back to life. The artisan, Yassin Arab learned the glassblowing craft from his father when he was a child, and after the town was liberated from terrorism, he returned to his small facility, where he worked to restore it and start working again. Arab does not hide his enormous passion for the craft of glassblowing and his belief in the need to preserve this ancient Syrian heritage. Regarding the working mechanism, the artisan explained to SANA that he uses recycled glass, melts it again in the oven at high temperature, and then chooses a specific shape for its manufacture, whether hookah bottles, vases, plates, small jugs, fish houses for decoration, decorated cups and antiques of different sizes. After that, t he piece is blown, rotated and processed by the artisan until it takes its final shape using white and brown colors, and once the manufacturing of the product is finished, it is decorated and colored to give it the required aesthetics. For his part, Hussein Najjar noted that he learned the craft of blowing glass manually since he was young and has been working in this field for 40 years. He added that he is able to make any shape or glass container, using his imagination, and considered that the art of glassblowing is one of the types of plastic arts. Traditional glassblowing is a profession that dates back more than two thousand years (since the time of the Phoenicians) and was included in December 2023 by UNESCO on the list of intangible cultural heritage of humanity that needs urgent preservation.

Intangible heritage contributions to the protection of national identity
Amina Abbas
Heritage researchers and scholars agree that the Levant region is the most important heritage repository for humanity, as it has the oldest and richest heritage, and this heritage, both material and intangible, was coveted by the colonists since ancient times to destroy culture and identity, there is no identity without heritage based on it, and no heritage without identity, so Syria is keen through its institutions and bodies to emphasize the importance of preserving it.
Hence, the Quneitra branch of the Arab Writers Union, in celebration of World Heritage Day, decided to hold a seminar in the Levant Hall of the National Museum entitled “Contributions of Intangible Heritage to the Protection of National Identity ” with the participation of Dr. Amal Daccak, Professor Ruba Al-Diab, Qas Ghassan Houranieh and Dr. Rima Diab, Head of the Quneitra branch of the Arab Writers Union. It represents not only traditions and the past, but society in all its layers, and links the past to the present and the future, and it is a means for each people to prove its existence in the world and its authenticity, while stressing that the intangible heritage contributes to the preservation of identity and personality. Our identity and our heritage in the era of globalization, which is trying to eliminate our heritage and culture to be part of this lost world.
This was also confirmed by Dr. Dakak in her participation: “The Syrian tangible and intangible heritage is rich in its authenticity and civilization that dates back thousands of years, so it was and still is coveted by the colonists who stole many treasures to be in their world museums, and their war on Syria recently was aimed at destroying culture and identity and stealing antiquities. ” It is an integrated cultural unit formed by man throughout his long history with his creative thinking, observations, reflections and experiences accumulated generation after generation, and it is the social environment occupied by man and the components and pillars produced by previous generations until it reached subsequent generations and has the function of supervising the behavior of the individual and his sociocultural upbringing because it is a reflection of the social, intellectual and cultural life of peoples. As Daccak pointed out, the identity is the set of psychological, social and civilizational features of our nation throughout its long history, and the folklore constitutes the identity of a homeland rich in culture and civilization, calling in the era of globalization to seek to preserve our cultural identity and heritage, which represents this identity to face the challenges of globalization that invade us and want to eliminate our identity and culture. And our originality by drawing different borders in which national identity is absent and killing people in their country.
Because the Levantine rose and its associated practices and traditional crafts are important Syrian heritage elements inherited from generation after generation, and was included by UNESCO in 2019 in the list of intangible human heritage was talked about by Professor Al-Diab, who was crowned queen of roses and became Syrian ambassador to the world: “The Levantine rose was found painted on the wall of a palace on the island of Crete and was introduced to France during wars. As the poet Nizar Qabbani wrote about her,“ I am your Damascene rose, O people of the Levant, and whoever finds me should put me in the first vase, ” referring to the areas of its cultivation in Damascus countryside and Ghubartha. The project was launched by the Syrian Secretariat for Development in 2020 with the support of First Lady Asma al-Assad, affirming that Syrians consider the Levantine Rose an important part of their culture. The Ministry of Tourism has taken it as its slogan, in addition to many medical and cosmetic companies and building a path that is architecturally designed in the form of a Levantine Rose, explaining that the elements of the Syrian intangible cultural heritage include: Traditions and expressions “qaṣīda, mawwāl, ataba, dalaouna, zaghārīd, folk proverbs ” and the arts:“ Aleppo qadūd, coastal dabka, Circassian dance, Syriac church music ” Social practices “preparing and serving bitter coffee ” Knowledge and practices related to nature and the universe:“ cupping, traditional architecture ” Skills related to traditional crafts “wooden mosaic, brocade ” The crafts associated with the Levantine Rose ”, and that the elements of the intangible Syrian heritage included in the lists of human heritage are: falcon hunting, shadow fiction theater, Levantine Rose, Aleppo cod, glass blowing and making sticks and playing on them.

Content: What is the reality of traditional and traditional professions in Syria?
DAMASCUS – The traditional professions and crafts in Syria were not immune to the repercussions of the war. In light of the difficult economic and security conditions that the country has been witnessing for more than a decade, these professions are suffering from an unprecedented decline related to production and market conditions, which makes them today threatened with extinction.
The head of the Union of Craftsmen in the province of Latakia Jihad Pro, in a recent statement to the local newspaper Al-Watan, the decline of the production of handicrafts and handicrafts of various kinds by 50% within the province, considering the high costs of production inputs and increased income taxes as direct reasons for this decline.
Bassam Qalaji, head of the artisanal association for confectionery in Damascus, told the local newspaper Global last month that more than half of the confectionery craftsmen had stopped producing and switched to other professions due to low demand and insufficient profits.
Successive statements reveal the reality of Syrian traditional and traditional crafts, which are suffering under the weight of the economic decline that the country is suffering from.
This situation has prompted thousands of craftsmen to close their workshops and shops and switch to other jobs, or migrate and move their work abroad, amid the real threat of the disappearance of many traditional traditional traditional professions and handicrafts, which constitute vital sectors of the economic sector in the country and an integral part of its cultural identity.
What are the main reasons for this decline?
How does it affect the economic life of the country?
Lack of support and unequal competition
Anton, a 42-year-old Damascene craftsman and former owner of a mosaic workshop in rural Damascus, says his struggle for years to keep his workshop open, producing and selling enough to pay its workers has been futile.
He adds in an interview with Al Jazeera Net: "I tried hard to maintain the workshop and its workers for as long as possible, but the constant high prices of wood (local and imported) in an inappropriate manner, the long interruption of electricity (16-18 hours a day), and the low demand for mosaic in the domestic and foreign market, all factors forced me to lay off workers, and later to close the workshop after months, during which I received only two orders."
In addition to these factors, Anton attributed the low demand for "original" mosaics and other handicrafts and heritage artifacts (copperware, damask, antika, textiles) to:
The reality of the market at the moment in the absence of tourists.
• The decline of external demand for the commodity as a result of the interruption of trade relations with foreign markets.
• Migration of brokers and traders and thus reduced export.
• Unequal competition.
With heritage products becoming “more than luxury ” for Syrians suffering from poor purchasing power (average monthly salaries of about $20), and the lack of support for craftsmen and awareness of the importance and authenticity of these products by trade unions and government agencies, Syria ’ s craftsmen face major challenges to continue their craft.
Although there are no accurate figures on the number of craftsmen who have been driven by working conditions to emigrate outside the country, the head of the Damascus Craftsmen ’ s Union, Ali Qarmashti, revealed in an interview with the local news website Click News last year that the percentage of Damascene craftsmen migrating has become very high, especially among young people.
Repellent economic and social policies
In addition to the direct economic factors that led to the decline of traditional crafts during the past few years, represented by the high prices of raw materials, the poor reality of services, and the decline of the sale and purchase movement, there were indirect factors that affected these crafts.
Syrian economist Younis Karim believes that the artisan crisis began in 2008 after being subjected to great pressures due to the change of the general economic orientation in the country.
He said in an interview with Al Jazeera Net: "Since 2008, the authorities have put their hands on the spread of these industries due to the importance of their geographical location, and work to change their features in favor of wealthy investors, or provide them as donations to countries that Damascus seeks to establish bilateral relations with."
According to the expert, the reality of the work of traditional crafts after 2011 became more complex and difficult with "the continued adoption of economic and social policies by the regime that restrict the owners of these crafts, exclude them from support, take their places of deployment, in addition to the cessation of exhibitions and the difficulty of participating in external events because of the political positions of the regime.
Karim explains that the family and social disintegration suffered by Syrians as a result of large-scale migration during the last decade was an added reason for the decline of these crafts, which “relied on inheritance between generations of the same family as a tradition followed by Syrian craftsmen long ago. ”
Kilo to Piece and Pieces
It seems that some traditional crafts and crafts are in the same trench with traditional crafts in their war against extinction, where the owners of many traditional crafts are no less original than those of heritage, especially the confectioners from the high costs of raw materials in production, high costs of energy stands, and successive losses due to the reluctance of citizens to buy expensive Arabic sweets.
Suhaib, 55, owner of a sweets shop in the Jazmatiya area of Damascus, told Al Jazeera Net: "Days pass without selling a total of a kilo of various items, and two years ago the stagnation of goods in the shop became a familiar phenomenon to us, and had it not been for the holiday seasons, and some occasions and weddings held here and there, we would have closed long ago."
Al-Halwani Al-Damascene adds in an interview with Al-Jazeera Net: "Our profits, and the profits of most of the shops of Halwanis in Damascus, have decreased by a large percentage since the beginning of the economic crisis in the country."
Al-Halwani pointed out that the price of a kilo of some varieties of Arabic sweets has exceeded 400 thousand pounds recently, adding: "Which is not able for Syrians to buy, so we have become selling methods in which we rely on small quantities, so we sell baklava, crystal, shaped, asian, brominated and other items in ounces, grain (piece) and two grains to keep the sales movement, and do not stop customers from our shop."
As for the reasons why sweets in Damascus stopped working and many of them emigrated outside the country, Al-Halwani said: “Many reasons start from the large annual taxes that are inconsistent with high operating costs and low profits, in addition to the high prices of commercial electricity and fuel needed to operate shops and laboratories, the huge increase in the prices of raw materials, the high wages of workers, and the reluctance of customers to buy these sweets except on occasions. ”
High prices
Prices of food, nuts and other components of Arabic sweets have risen by varying rates recently, as the price of a kilo of animal margarine reached 150 thousand pounds ($equivalent to about 2511 pounds), while the price of a kilo of pistachio love rose to 300 thousand, and the price of a kilo of walnuts to 120 thousand.
The prices of popular sweets such as Al-Barazek and Al-Ma ’ amoul in Damascus markets, by the holy month of Ramadan, were between 100 and 130 thousand pounds per kilo, while the prices of medium and luxury sweets such as “Al-Belouria ”,“ Al-Mashkeel ”, “Kool and Shakour ”,“ Aish Al-Bulbul ” and “Baklava ” ranged between 250 and 500 thousand per kilo, which is equivalent to the salary of a Syrian employee in the public sector.
The head of the artisanal association for confectionery industry, Bassam Qalaji, attributed this rise in confectionery prices to the government lifting subsidies on oil derivatives, which led to a direct increase in costs by 150%, pointing out that raising the price of electricity by 5 times will lead to an increase in the price of about 650 products.
Qalaji said in a statement to the local newspaper Al-Watan last month that the largest number of confectionery craftsmen emigrated, and their first destination was Algeria followed by Germany.
In March last year, the head of the artisanal association for the confectionery industry revealed that 70% of the workshops of the confectionery industry were closed due to the economic crisis and the low demand for sweets and refreshments.
A severe blow to the economy
This gradual disappearance of traditional crafts is a painful blow to the Syrian economy, says economist Younis Karim, “For decades these crafts have been the largest incubator of Syrian labor, and their contribution to the economy before 2011 ranged from 40 to 50%. ”
This is what Matanios Habib, a researcher and former Syrian oil minister, said in a research paper entitled “The private sector in Syria ” (2005), when he pointed out that the private industrial sector in Syria tended to invest in crafts for fear of nationalization policies, whether during the era of Syrian-Egyptian unity (1958-1961) or after the revolution of March 8 (1967).
Karim stresses that the crisis of workers in traditional crafts, such as confectioners and others, dates back to before 2011, specifically to the period between 2007 and 2009, when there was “an attempt by the regime to pressure the owners of traditional crafts and crafts by forcing them to pay taxes, and to keep them away from city centers in favor of large investors. ”
Younis Karim believes that the gradual demise of these crafts will have negative effects on the Syrian economy because of their role in "providing job opportunities beyond those provided by large laboratories and their excellence in ease of operation and achievement, and the ability to spread.
