Abstract
New data on distribution, ecology, and size composition of rex sole Glyptocephalus zachirus in the northwestern Bering Sea in summer are presented. Fish of this species were recorded at the depths of 120–718 m, mainly within the warm Intermediate water mass, under water temperature of 2.6–4.9 оC at the bottom, with the maximum of distribution density in the bathymetric range of 200–400 m. The fish of 11–49 cm in length prevailed in the trawl catches. The juveniles avoided shelf areas and dwelled in the upper bathyal layer only. The main habitat of rex sole is supposedly subjected to influence of the warm Navarin Current.
