Klovach, V. Roi] Results of study of sock-eyed salmon Oncorhynchus nerka from the Apuka River—the largest river of the northeast of Kamchatka—inflowing Olyutorskii Bay of the Bering Sea are presented. It is established that the school of the Apuka River is represented by the early-run sock-eyed salmon that spawns in Lake Vatyg-Gytkhyn located in the lower part of the basin and by individuals of the later run that spawn in the upper reaches of the river. Early-run sock-eyed salmon appears in the river with signs of spawning changes and a high value of gonadosomatic index (GSI). Late-run sock-eyed salmon migrates to the river without signs of spawning changes and with a relatively low GSI. The age composition of spawners of the early- and late-run sock-eyed salmon is different.
