Fish from the Baltic sea is dangerous for children and pregnant women

Eating fish from some marine bays and rivers of Russia is dangerous for health, because fish accumulate pollutants and toxic substances, said experts at a media conference in RIA Novosti on Wednesday.

“I wouldn’t eat fish caught in the Gulf of Finland, in the Taganrog Bay and very close to Vladivostok,” – said senior researcher of the Institute of Oceanology. P. p. Shirshov of RAS Vasily Spiridonov.

As for rivers, the most polluted rivers of the Azov-black sea basin, warned the scientist. In addition, dangerous fish caught in the Moscow river.

At the same time in most of our seas, according to Spiridonova, the situation quite well.

However, as noted by the expert of WWF, the fisheries oeconomica Alexander Moiseev, “fish from the Baltic sea in Sweden is not recommended to eat pregnant women and children.”

In addition to the wild fish living in contaminated waters, can also be dangerous to the health of fish and seafood, farmed in cages, especially in the Mekong Delta, warn biologists.

“Prawns, which were so popular in Russia, actually iskusstvennost in Vietnam and China on the artificial stimulants and antibiotics,” said Spiridonov.

Currently about half of the production of fish and aquatic invertebrates are grown in artificial conditions in aquaculture. On the one hand, the more farmed fish, the less the need for the fishery, but on the other hand, aquaculture has a number of significant negative effects, according to the WWF guide for buyers and sellers of fish products.

For example, to feed salmon in sea cages is a huge amount of natural small fish: to grow one kilogram of salmon requires a minimum of 1.5-2 kilograms of other fish. Farms themselves are a source of waste dumped at sea, diseases and parasites that infect wild populations. In addition, synthetic additives, antibiotics and dyes – will inevitably affect the quality of the products and not always safe for humans.
