Orlov, O. Zolotov] Based on materials of trawl studies performed from 1992 to 2002 off the Pacific coast of Kamchatka and the northern Kuril Islands in the framework of the integrated (VNIRO, KamchatNIRO, Sakh-NIRO) program on the study of fishery resources of the continental slope, data on the distribution and biology of rock greenling Hexagrammos lagocephalus were analyzed. It was elucidated that this species is extremely eurybathic; the range of its seasonal vertical migrations embraces depths of 1-2 m in summer, and in the spawning period and up to 665 m in winter. The spatial distribution has a mosaic pattern, maximum concentrations were recorded at the slope and shelf of the Shumshu Island and the southern extremity of Kamchatka. The size, weight, and sex composition, and the maturation and feeding of the rock greenling are considered. Maximum fish sizes in trawl catches are 58 cm and 2.63 kg; sex composition is characterized by the domination of females in all size groups (79%). The bulk of feeding consisted of Cephalopoda, small crustaceans—Amphipoda and Isopoda—as well as the eggs of fish and Gastropoda. With an increase in sizes, the greenling passes from feeding on small benthic organisms to larger movable forms.
