Introduction:
Most of the chum salmon (Oncorhynchus keta) of the Sakhalin-Kuril basin is of artificial origin. Thanks to the work of salmon hatcheries in the coastal areas of Iturup Island, more than 20,000 metric tonnes of this salmon are produced annually, whereas returns of wild fish before the start of the fish farming program in the Kuril Islands amounted to, at best, 500–700 metric tonnes (Makoedov and Makoedov 2022).
