Pacific salmon monitoring results in Sakhalin Bay in 2023

Abstract

The purpose: getting up-to-date information about the summer anadromous migration in 2023 and the qualitative indicators of Pacific salmon in the Sakhalin Bay (Khabarovsk Territory).

Methods used: the work was carried out in accordance with the methods generally accepted in fisheries research.

Result: Up-to-date information about the beginning of spawning approaches of pink salmon and chum salmon in the Sakhalin Bay has been obtained. The number of fishing areas and the dynamics of pink salmon catch in the southern, central and northern parts of the Sakhalin Bay are indicated. It is noted that the commercially significant approaches of pink salmon began from the southern part of the bay. The main biological characteristics of pink salmon and chum salmon suitable for the rivers of the Sakhalin Gulf in 2023 are given.

Practical significance: Information on the migration of Pacific salmon in the Sakhalin Bay and their qualitative indicators will be used in the preparation of materials justifying the projected catch volumes in subsequent years, as well as in the regulation of Pacific salmon fishing in the Sakhalin Bay area.
