Abstract
The article studies the size-age structure, growth, and feeding of stone cockscomb Alectrias alectrolophus from several regions of Taui Bay, the Sea of Okhotsk. The research revealed differences in the size of even-aged fish. The largest average length — 91.6 mm — was observed in individuals from Nagaev Bay, the largest mass — 4.4 g — in individuals from Motykley Bay, the smallest average length and weight — 86.6 mm and 3.0 g, respectively — in individuals from Odyan Bay. The highest growth rate was typical of stone cockscombs from Motykley Bay, while the lowest growth rate — of individuals from Odyan Bay. The found differences in the fish growth rate correlate with environmental conditions and levels of food supply in the four studied areas. The basis of the feeding in all studied areas was formed by Amphipoda (45.1%) and Polychaeta (29.4%).
