Abstract Excerpt:
At present, Pacific salmon (Oncorhynchus spp.) stocks in the Russian Far East are at a high level that is reflected in their catches. The mean total catch over the last five years (2018–2023) constituted 478,000 metric tonnes. More than half of the total salmon catch in the Far East is provided by pink salmon (O. gorbuscha). As a rule, it is the pink salmon catch that determines the overall success or failure of the annual salmon fishing season. From the early 2000s to mid-2010s the southern stocks, mostly the East Sakhalin stock, contributed essentially to the total catch of pink salmon, providing up to 70% of the catches in that period (Fig. 1a). From 2016 on, pink salmon stock on Sakhalin Island decreased substantially, partly due to excessive fishery pressure (legal and illegal) but also because of the climatic variations. In particular, the decline of catches in both odd- and even- years coincided with deterioration of thermal conditions in the southern Sea of Okhotsk, which obviously was the wintering area for most of the stock (Fig. 2).
