Distribution, Feeding, and Some Physiological Parameters of the Pacific Herring from the Gizhigin and Okhotsk Populations in the North Part of the Sea of Okhotsk in the Spring Season

摘要

The distribution of the Pacific herring of various sizes from the Okhotsk and Gizhigin-Kamchatka populations is discussed. The dependence of herring food composition on the condition of the plankton community is demonstrated. In the spring season the feeding rate of juveniles and fattening adult herring depended on the degree of its fatness and on the maturity of the gonads in the prespawning period.
