Climate change is causing the boundaries between the Arctic seas and the northern regions of the Pacific and Atlantic oceans to become increasingly blurred.
As a result, the inhabitants of warmer waters are migrating further north, said Alexey Orlov, Doctor of Sciences, Head of the Oceanic Ichthyofauna Laboratory at the Shirshov Institute of Oceanology of the Russian Academy of Sciences.
According to him, scientists analyzed the data from various expeditions from the mid-1970s to 2020 and discovered an increase in the number of some boreal fish (halibut, cod and pollock) north of the Bering Strait.
For example, in 2019, a fairly large number of Pacific pollock was discovered in the Chukchi Sea. As the specialists of the Pacific branch of the All-Russian Institute of Fisheries and Oceanography managed to find out, part of the pollock survives safely in these latitudes even in winter, www.ttelegraf.ru reports.
