Abstract

The results of trawl surveys at western part of Bering Sea and Okhotsk Sea at the R\V «TINRO» and R/V «Professor Kaganovskii» in the fall 2021 are analyzed. These studies provide data on spatial distribution, abundance and biomass of fishes, cephalopods and jellyfishes in the epipelagic layer of the Bering and Okhotsk Seas.
