Abstract

Data on the biological structure of flounder species in the northern part of the Sea of Okhotsk based on samples collected in 2002–2019 are given. It is shown that the conception developed on literature sources (Моисеев, 1953; Фадеев, 1987; Борец, 1997) that flounders in the northern part of the Sea of Okhotsk are small-sized species living in extreme conditions, does not confirm our data. The maximum size and age of the flounders in examined area are comparable or even exceed those of similar species from the adjacent areas of the Sea of Okhotsk and, in general, the North Pacific. Data on the temporal dynamics of their biological parameters are given.
