Fish that are not grown artificially list

For reference:

The richest in vitamins, minerals and omega-3 acids is sea fish: pink salmon, chum salmon, cod, haddock, horse mackerel, pollock. Of particular importance in the human diet are fatty fish species: salmon, herring, mackerel. River fish - carp, carp, bream, crucian carp, perch, pike - are also rich in vitamins and minerals, but inferior in fat to sea fish.

Fresh fish has a slightly sweet smell, but not too fishy or muddy. Although some varieties of river fish (for example, catfish) can give off "mud". To get rid of this "aroma", the fish is specially washed in cold salt water.

Do not ignore the fins either: they should fit snugly to the body and not intertwine. If the storage conditions are not followed, the fins will be unnaturally positioned and may also be damaged.

The tail of a good fish should be straight and not curled up or dry. The abdomen is flat, not swollen, without spots. If gutted fish is lowered into water, it should drown. This suggests that you have been sold a really good fish. If she surfaced belly up - you bought a low-quality product.

When buying chilled fish fillets, pay attention to how they are cut. The pieces should be even, and in appearance it should be dense.

Thanks to the mother of my patient, for whom I began to look for information about Dorado fish during the examination, your humble one cannot understand how she got to a wonderful site that she could not help but share with you. In the Schools of Healthy and Delicious introductory course, we go into detail on the main problems associated with fish, but until now I could not find a sufficiently informative list of edible fish and fish contaminated with mercury until I discovered this site.

The site helps to select fish and seafood that are least contaminated with heavy metals. It is also intended for those who prefer to eat food that does not harm the environment, so some fish species for which there is no medical data are mentioned there simply because their breeding does not harm the environment. Be careful and look for information about the degree of infection!

Upd: For readers from Russia: this site contains not only American information at all, it mentions a lot of fish species that are caught in Russia. By default, the fish of the Russian catch is considered more contaminated, because Russia does not comply with international standards and does not allow inspectors, but in this case it is the breed that decides, so if the fish does not accumulate mercury, then it will not accumulate it in Russia either.

Translate the name of the breed: Russian-English-Hebrew.

Types of fish you can eat:

Anchovies, northern (Engraulis mordax), European (Engraulis encrasicolus) and Japanese (Engraulis japonicus).

American lobster (Homarus americanus)
Atlantic mackerel (Scomber scombrus).
Atlantic haddock (Melanogrammus aeglefinus).
Sardines (Sardinops sagax).
Pagra, she is sea bream, she is thai (Pagrus pagrus).
Salmon (Salmo salar), wild, from Alaska. Farmed salmon and wild salmon from Washington DC are contaminated with PCBs and are dangerous to eat more than once a month and less often just harmful.
Atlantic herring (Clupea harengus).

As far as I know, there are no similar lists in Russian (at least not on such a scale and not from such an authoritative source), so the dissemination of information is encouraged in every possible way.

I try to eat exclusively plant foods, but I can't refuse fish and seafood. I love them very much, and therefore I am offended and scared to read about the fact that in reality fish can be not only not useful, but also extremely dangerous. To reduce the health risks that can arise from eating fish and seafood, there are a few rules to follow.

1. Avoid farmed fish. There are several reasons.Firstly, such a fish grows in habitats that are not natural for it, it moves little, and therefore the fat formed in it is absolutely useless. Second, farmers typically use antibiotics to prevent disease and fight parasites, and hormones to boost growth. And thirdly, the food for these fish contains substances hazardous to human health (for example, pesticides). All these wonderful additives enter our body along with grilled salmon steak or dorada ((((

2. Unfortunately, the wild fish is also not all right. Today the oceans and seas are extremely polluted and radioactive, and fish absorb toxic and radioactive substances that are dangerous to human health. Most of them accumulate in large fish. Such hazardous substances include heavy metals and mercury. Mercury is a neurotoxin that causes people to lose memory, vision, cardiovascular diseases, etc. Doctors strongly recommend that pregnant women exclude products containing mercury, as it causes mental retardation, deafness, blindness and cerebral palsy in children.

Here is a list of fish that should be avoided altogether, as they contain the highest concentration of mercury: marlin, tile, swordfish (my husband's weakness, which caused high levels of mercury in his body), shark, king mackerel, bigeye tuna and yellowfin tuna.

And this fish is recommended to be consumed no more than once a month, the maximum portion is 180 grams: Chilean sea bass, bluefish, sea bass, Spanish mackerel, yellowtail tuna.

Fish from the following list can also be eaten in small portions no more than 6 times a month: striped bass and black perch, carp, Pacific cod, white croaker, Pacific and Atlantic halibut, lobster, dorado, monkfish, freshwater perch, coal fish, stingray, snapper, gray croaker, striped tuna.

Finally, it is recommended to eat fish from this list no more than twice a week (a portion of 180 grams): anchovy, butterfish, catfish, bivalve molluscs, crabs, crayfish, croaker, haddock, hake, herring, Atlantic mackerel and Japanese mackerel, mullet, oysters, river and sea flounder, salmon, sardines, scallops, shrimps, sole, squid, telapia, freshwater trout, "white" fish, hake.

3. When cooking fish, keep in mind that toxic substances are mainly found in fat, and it is better to choose cooking methods that involve melting the fat, such as grilling.

4. Avoid canned fish and any industrially processed fish. I hope there is no need to explain why)))

5. I am also often asked about sushi, because there is an opinion that it is a very healthy food. However, in light of the above, it is clear that this is not the case. And one more thing: the combination of fish and rice (especially processed white rice) is very bad for digestion, so sushi or rolls are the wrong choice in a Japanese restaurant. It is better to choose sashimi - if you are not afraid of radiation and mercury))).

With this material, we continue the series of translated articles by Daniel Knowland (translations made by himself), Jamie Oliver's scientific adviser on nutrition. Another essay is devoted to the topic of fish and how it is grown and harvested in modern conditions, which fish is useful and which is harmful, and how to choose it correctly. The second part of the post - information on the same topic, in particular, about the situation in Russia, it is from other sources (list of references at the end of the post).

Artificial fish farming - all the pros and consToday in the UK, a huge amount of fish and seafood is grown in artificial conditions.Here it is necessary to make a reservation that any livestock product, strictly speaking, is not completely natural, but mankind cannot do without breeding farm animals.
Modern society sets new standards for the consumption of products, and manufacturers have to reckon with them. In this regard, the need arose for artificial fish breeding. In this article, we will look at the positive and negative aspects of this activity.What is it for - to breed fish?On the globe, there are still such corners where wild plants and meat of wild animals and birds serve as the main food source. However, in developed countries, this situation is no longer encountered. Berries, mushrooms, hare or venison - these are, perhaps, all types of “not grown” products that can be found on the menu of a modern person. We are used to the fact that meat, poultry, dairy products, fruits, vegetables, grains are mainly produced by agricultural enterprises. With fish and seafood, the situation is somewhat different. Both commercial (caught in the natural environment) and artificially grown fish fall on our table. As the world's population grows, so does the demand for foods rich in protein and, at the same time, affordable. And the word "ocean" is increasingly associated with concepts such as "overfishing", "endangered fish species", "ecological safety". Indeed, as a result of many years of irresponsible attitude of the fishing industries in many countries to the environment, the populations of some representatives of the marine fauna have been significantly reduced, and today there is an active fight against overfishing. In addition, programs are underway to help buyers choose fish from sustainable sources. The most famous organization in this area is the Marine Stewardship Council (MSC). However, despite some progress made, human activities continue to cause significant damage to the ocean ecosystem. Populations of commercial fish continue to decline. This is especially true of such favorite species by buyers as cod, haddock and tuna. As an alternative to traditional fishing, artificial fish farming (its other name for this activity is “aquaculture”) has been actively developing over the past few decades. , the phenomenon is not new. But currently there is a real boom in this area. And new techniques and technologies can significantly reduce the degree of negative impact on the environment when using this method.What types of fish and seafood are grown in marine farms?Salmon, rainbow trout, sea bass, bream, pangasius (often called bassa or river catfish), shrimp are the most common types of farmed fish and seafood. It is believed that today in developed countries, about half of all fish and seafood consumed is grown in fish farms. Supermarkets and restaurants in the UK are likely to buy or offer farmed salmon. Commercial salmon is much less common on the market, and it will cost significantly more.

What is artificial fish farming?Typically, the artificial breeding process is as follows:1. With the help of selection, a parent is selected that is most suitable for artificial breeding. The eggs of the fish are placed in small tanks. The grown fry are then transferred to larger tanks.There, the fry are fed, which are under constant supervision.3. When the fry have reached a weight of about 150 grams, they are moved to large ponds or fenced-in areas in the sea (such as those shown in the picture above).4. Then the fish receives concentrated feed until it gains the desired weight. Throughout the entire time, the condition of the fish is constantly monitored, often using underwater cameras. When the desired weight is reached, the fish are sent to processing factories for subsequent evisceration and packaging.Do all types of cultured fish have similar consumer properties?It is difficult to find two completely identical livestock farms. The same can be said for fish farms. Each manufacturer has its own standards to ensure favorable conditions for keeping fish. Each farm uses its own methods to reduce its harmful effects on the environment. However, the lack of uniform standards makes life difficult for customers. Environmentally friendly eggs, chicken and pork are no longer a rarity on store shelves. Products with the labels "Red Tractor", "RSPCA Approved", "free-range animal meat" and "organic products" are widely represented. We do not yet have such a choice for farmed fish and seafood. Nevertheless, despite the lack of clear guidelines when choosing fish (for example, salmon), there is still some help for the buyer. There are various programs and organizations that aim to reduce the negative impact of fish farms on the environment. Some of them are listed below:

• RSPCA Assured. Within the framework of this program, mainly checks of the conditions of keeping fish are carried out.
• Global G.A.P. Products bearing this label are tested for compliance with food safety and environmental standards. Also, the presence of the program certificate guarantees that the products are received from trusted manufacturers.

• Best Aquaculture Practices and Fish Farms Board of Trustees

• (Aquaculture Stewardship Council) are comprehensive programs. Their goal is to reduce the negative impact on the environment, ensure the environmentally sound and rational use of natural resources and improve food safety.

• Soil Association / Organic. This organization is mainly concerned with environmental impact and the use of only organic fertilizers in agriculture.

Many UK retail stores join one or more of the programs listed above. In this way, supermarkets demonstrate that they support sustainable food production.How safe is fish farming in terms of environmental impact?Salmon farming on a large scale has been started by fisheries not so long ago: over the past few decades. However, the development of the industry proceeded at a rapid pace. It took some time to fully understand the impact of such activities on the environment and human health. Over the years, fish farms have made many mistakes. And the mistakes they made did not reflect in the best way on their reputation. Cases of fish escape from cages are known. The result was the crossing of artificially bred and wild individuals. Other side effects include pollution of the sea and underwater currents, the use of environmentally unsafe fish food, drug overdose and the use of questionable chemicals. The industry is far from perfect. However, the mistakes of the past were not in vain, and fish farms are undergoing major changes. New technologies came to the rescue. Now it is possible to observe the behavior of fish and collect data on the state of the environment.Robotic systems monitor the optimal level of fish feeding and oxygen content in the water. Much remains to be done in order to minimize the damage that fish farms can do to the ecosystems of the surrounding areas. in reservoirs specially built on land) does not cause much damage to the environment. Therefore, the negative consequences of the activities of such fish farms often go unnoticed. The quality of the feed is of great importance for the environmentally friendly farming of fish. Large fish, such as salmon, naturally feed on smaller fish. Therefore, in fish farms, salmon are fed mainly with fish protein and fish oil. Such food is made from commercial fish. The quality of farmed salmon directly depends on how environmentally friendly the fish it feeds on is. The development of new technologies makes it possible to reduce the proportion of commercial fish in the feed. This makes it possible to use marine resources more efficiently.

What kind of fish should you buy?A variety of organic foods in the diet is the key to a conscious approach to nutrition. We always recommend that you include a wide variety of fish and seafood in your diet. Don't settle for just one type of fish; farmed fish and seafood such as salmon, haddock or shrimp are best purchased from a reputable supplier. It will not be superfluous to ask if there is a certificate for the product. Certain supermarkets require certification (such as RSPCA Approved) for salmon products. For Jamie Oliver's restaurants and shops, we always buy fish from personally verified suppliers. Or we choose products whose quality is confirmed by trustworthy certificates.
Completion of translation of D. Knowland's article.Now let's turn to the Russian marketThe situation on the Russian market has changed dramatically with the introduction of sanctions: before their introduction, 84% (!!!) of the red fish consumed was Norwegian salmon. Now the situation has changed: from abroad we are supplied with goods from Asia (mainly telapia and pangasius), the source of salmon is the Faroe Islands and Chile; pollock, cod, haddock, catfish, red salmon and a small proportion of salmon come from the Far East and the Barents Sea. Only our domestic fish is commercial, caught in the sea. The rest of the fish is the result of artificial breeding or a product of "aquaculture". Why is it only our fish that is commercial? The answer is very simple: it is just that in our country there was still no special equipment and technologies for fish farming. Now, with the introduction of sanctions, farms that breed salmon on an industrial scale (for example, the Murmansk Salmon brand of the Russian Sea company) are beginning to appear, which purchase full production cycles (equipment, feed, medicines) in Norway. The first harvesting of 4 thousand tons of commercial salmon under the Murmansk Salmon brand in the Barents Sea began in June this year and will end in October. Next year the company plans to receive 10 thousand tons of fish. By 2018–2020, it plans to produce 25 thousand tons of salmon. We emphasize once again that all equipment for the full cycle of fish farming, including feed, is purchased from Norway.

So what's the problem with “aquaculture”?And everything would be fine, but too often recently voices have been heard that claim that artificial fish farming is carried out with huge violations.

In the same way that livestock was raised in Europe with high doses of antibiotics, fish is now being raised. Not only antibiotics are used, but also pesticides, which are designed to clean up excessively polluted water bodies (link to the French study film at the end of the post). Believe it or not - everyone's personal business. But nutritionists still urge to buy "wild" fish whenever possible, if there is no complete confidence in the supplier of aquaculture fish. It turns out that from the point of view of modern dietetics, our domestic commercial fish can still potentially bring more health benefits.

But, even "wild" fish can be harmful to healthRecent studies show that even the meat of commercial fish is often contaminated with chemical toxic substances: industrial enterprises actively release mercury, PCBs (polychlorinated biphenyls), dioxin and other pollutants into the environment, which enter the water and then along the food chain into fish. plichlorobiphenyls): belong to the group of persistent organic pollutants, the monitoring of which in air, water and soil is mandatory in developed industrial countries due to their high risk to the environment and public health.
PCBs were first produced in the United States by Monsanto in 1929. These are oily liquids that are not flammable and do not conduct electricity, but they conduct heat well. PCBs are resistant to acids and alkalis.

Due to these properties, they have found wide application as dielectrics in transformers and capacitors, as coolants in heat exchange systems, in hydraulic engineering, are part of plasticizers, paints, varnishes, lubricating oils, plastics, carbon paper, additives in household chemicals. The production of PCBs has been almost completely phased out all over the world. In 2001, most European countries signed the Stockholm Convention on Persistent Organic Pollutants for the earliest possible environmentally safe neutralization of these substances. The parties to this convention committed themselves to completely neutralizing PCBs available in their countries until 2028.

The best thing to do for your health is to introduce into your diet smaller fish instead of medium and large (old and large ones usually contain more harmful substances) and shellfish, which are less likely to contain harmful substances. In the United States, the US Department of Conservation and the Environmental Defense Fund regularly publish data on the content of harmful chemicals to human health in various types of popular seafood. There is no such monitoring in Russia.Below is a list of fish species in the waters of the oceans according to the degree of contamination with mercury and PCBs.It is recommended to completely avoid: - Striped wild perch - Pelamida (!!!) - American eel - King mackerel - Shark - Wild sturgeon (!!!) - Sword fish - Common tuna (!!!) once a month): - Summer and winter flounder - Yellow perch - Big-headed tuna - Eat moderately (at least 2 times a month): - Seabass (an aquaculture object, in Russia only such irina_co is on sale) - Blue crab - Grouper- Toothed rasp - King mackerel - Salmon (aquaculture product) - Sea spotted trout - Snapper Eat more often (but less than 3 times a month): - Red-tailed snapper - Atlantic sturgeon - Blackfin tuna - Longfin tuna, canned - Yellowfin tuna once a month): - Anchovies - Catfish - Bivalve molluscs - Cod (Atlantic) - Crabs - Langoustes - Haddock - Halibut - Herring - Lobsters - Atlantic mackerel - Dorada - Mussels - Oysters - Pollock - Sardines - Wild salmon - Crawfish - Scallops - Pestilence Unfortunately, in Russia, we have not yet created similar safety lists for different types of fish, so there is simply no place to find out about the level of this or that toxic substance in fish. Analyzes of the organization "Roskontrol" so far concern only the grade and volume of ice added to frozen products.Black Sea flounder Kalkan:

"... NORWEGIAN SALMON IS THE MOST TOXIC FOOD IN THE WORLD ..." - quote from the movie

The film is long, as much as 50 minutes, but after watching it, you will learn about many more aspects of the use of artificial fish imported from Asia and Norway.Most likely, you will not regret these 50 minutes spent.We are planning to make a synopsis of this film in the near future due to the fact that the information covered in the film is very important, significant and little-known. We managed to find this video in the "wilds" of the Internet with great difficulty:

What fish are not farmed artificially?

• Fish that are not grown artificially on farms and are not stuffed with antibiotics, growth stimulants, dyes, but are caught from natural water bodies, seas, oceans - this is pollock, catfish, flounder, perch, navaga, pink salmon, cod, salmon, saury, herring, chum ... The diet of fish grown artificially is poor, they do not have plankton and shrimp on the menu, which naturally affects the quality of the fish.

• Cod is grown in large quantities in Norway!

  There is a lot of cod in Russia from there, be careful

• The well-known and beloved fish with such a cute name - HERRING is not grown artificially on farms.

  At least, I have not found information anywhere that herring is grown artificially. It turns out that this particular fish is less dangerous for our body than salmon, salmon, carp, dorado, pangasius and telapia. And this is only a part of those fish that are grown artificially.

• When choosing fish, nutritionists advise buying one that has not been grown in fisheries. Such fish include: cod, saury, herring, pollock, pink salmon.

  Such fish are considered more useful, because, unlike their more fattened relatives, they were not fed with GMO feed and / or antibiotics.

  By the way, as an alternative, many summer residents are engaged in fish farming in nearby water bodies. Crucian carp is especially suitable for such purposes, which can adapt and reproduce well in almost any water. They grow well in captivity with veal. It is better to buy fish grown on farms not often.

To reduce the health risks that can arise from eating fish and seafood, there are a few rules to follow.

1. Avoid farmed fish. There are several reasons. Firstly, such a fish grows in habitats that are not natural for it, it moves little, and therefore the fat formed in it is absolutely useless. Second, farmers typically use antibiotics to prevent disease and fight parasites, and hormones to boost growth. And thirdly, the food for these fish contains substances hazardous to human health (for example, pesticides). All these wonderful additives enter our body along with grilled salmon steak or dorada ((((

2. Unfortunately, the wild fish is also not all right. Today the oceans and seas are extremely polluted and radioactive, and fish absorb toxic and radioactive substances that are dangerous to human health. Most of them accumulate in large fish. Such hazardous substances include heavy metals and mercury. Mercury is a neurotoxin that causes people to lose memory, vision, cardiovascular diseases, etc. Doctors strongly recommend that pregnant women exclude products containing mercury, as it causes mental retardation, deafness, blindness and cerebral palsy in children.

Here is a list of fish that should be avoided altogether, as they contain the highest concentration of mercury: marlin, tile, swordfish (my husband's weakness, which caused high levels of mercury in his body), shark, king mackerel, bigeye tuna and yellowfin tuna.

And this fish is recommended to be consumed no more than once a month, the maximum portion is 180 grams: Chilean sea bass, bluefish, sea bass, Spanish mackerel, yellowtail tuna.

Fish from the following list can also be eaten in small portions no more than 6 times a month: striped bass and black perch, carp, Pacific cod, white croaker, Pacific and Atlantic halibut, lobster, dorado, monkfish, freshwater perch, coal fish, stingray, snapper, gray croaker, striped tuna.

Finally, it is recommended to eat fish from this list no more than twice a week (a portion of 180 grams): anchovy, butterfish, catfish, bivalve molluscs, crabs, crayfish, croaker, haddock, hake, herring, Atlantic mackerel and Japanese mackerel, mullet, oysters, river and sea flounder, salmon, sardines, scallops, shrimps, sole, squid, telapia, freshwater trout, "white" fish, hake.

3. When cooking fish, keep in mind that toxic substances are mainly found in fat, and it is better to choose cooking methods that involve melting the fat, such as grilling.

4. Avoid canned fish and any industrially processed fish. I hope there is no need to explain why)))

5. I am also often asked about sushi, because there is an opinion that it is a very healthy food. However, in light of the above, it is clear that this is not the case. And one more thing: the combination of fish and rice (especially processed white rice) is very bad for digestion, so sushi or rolls are the wrong choice in a Japanese restaurant. It is better to choose sashimi - if you are not afraid of radiation and mercury))).
