Abstract
The paper presents research data on the distribution of Pacific herring (Clupea pallasii) biomass by the depth of its habitat, as well as the relationship of this distribution with biotic factors. The results underlying this article were obtained during trawl studies conducted in the Sea of Okhotsk in 2019. It was shown that the herring distribution is bimodal with peaks at depths of up to 20 meters and 90-100 meters. It was found that ≈ 70% of the total herring biomass in the summer-autumn period occurs at depths of up to 90 meters, and 29% of the remaining biomass occurs in the range of 90-210 meters. Herring was not found deeper than 410 meters. Based on the breaks in the graphs of the biological diversity parameters (Shannon index – H) and the ratio of the logarithms LgS / LgE obtained by the SHE method and for trawl stations distributed along the depth gradient, approximate boundaries of the distribution of fish biocenoses (biofacies) by habitat depth were established: from 0 to 13-15 meters, from 15 to 46-48 meters, from 48 to 121-123 meters, from 123 to 192-194 meters, then up to 250-252 meters. At the same time, it was found that herring is represented in three biofacies with a sufficient share of its biomass. It was suggested that herring is in neutralism or protocooperation with such species as liparis ochotensis and raven goby, northern atka mackerel, and in competition or predation with such species as pollock.
