#ARCTIC. #SIBERIA. THIS IS TAIMYR. Due to warming in the Arctic, the fish fauna in the Barents and Norwegian Seas has become more diverse by 66 percent. Scientists conducted research for 26 years – from 1994 to 2020, and for 20 670 trawls (a fishing method that includes dragging a fishing net through the water behind one or more boats) they caught 193 representatives of the ichthyofauna, goarctic.ru reports with a link on Eye on the Arctic.
26 years ago, researchers caught an average of 8 species of fish per trawl, and two years ago – 13 species.
In addition, experts found that 71 heat-loving species, such as commercial Atlantic cod, began to occur more often in the waters of the northern seas, and 23 arctic species – less frequently. Scientists attribute this to waters warming – fish from more southern latitudes get adapted to colder Arctic waters, and the ecosystem is being rebuilt.
Recall that Russian scientists put forward a hypothesis that the Arctic could heat up sharply due to powerful earthquakes. Warming Arctic waters are helping fisheries, and scientists have recorded the longest thunderstorm in the high Arctic.
