Spatial distribution of pacific herring <i>Clupea pallasii</i> on the northeastern shelf of Sakhalin Island in the modern period

Abstract

Spatial distribution of pacific herring Clupea pallasii in the Okhotsk Sea waters at the northeastern coast of Sakhalin Island is described on the data of surveys conducted in June-October of 1989 and 1997-2020 using bottom and midwater trawls and Danish seine. The herring distribute widely, with the main aggregations in the area with depth up to 100 m between the Lunsky Bay and Piltun Bay. These aggregations are formed by the native herring of the North-East Sakhalin population, whereas the herring in the deeper waters belong to the Okhotsk population.
