Abstract
The sockey salmon entry to the Bolshaya River on Zavyalov Island in the northern Okhotsk Sea was registered for the first time on July 26, 2021. Larger specimens were observed among the pink salmon going to spawn in this river, and one of them was caught by a brown bear at a distance of 300 m from the river mouth. It was the female of sockeye salmon Oncorhynchus nerka (Walbaum, 1792); the data on its size and weight are presented.
