Assessment of the Effect of Regional Climate Conditions on the Abundance of the Pink Salmon, Oncorhynchus gorbuscha (Walbaum, 1792) (Salmonidae), in the Sea of Japan in 1980–2023

—The relationship between catch dynamics of pink salmon (Oncorhynchus gorbuscha (Walbaum, 1792) (Salmonidae)) from the Sea of Japan and hydrometeorological conditions at spawning and feeding grounds is studied. Unfavorable conditions for pink salmon runs are an extremely low air temperature during incubation and water temperature during the estuarine–coastal life-history stage. Favorable conditions for pink salmon runs are a high air temperature during incubation and water temperature in the Tatar Strait during downstream migration and the early marine stage. Since 2018, cooling of waters in the Tatar Strait has been observed, which has affected pink salmon runs to the rivers of Khabarovsk krai and Primorskii krai. A shift of the dominant year classes in 1994 occurred under extreme hydrometeorological conditions at all life-history stages of pink salmon in the Sea of Japan.
