Data of trawling censuses (1996–2005) are used to analyze the specifics of the distribution of commercial fishes present in the northwestern Bering Sea in summer and autumn and forming accumulations in the waters of the Olyutorsky-Navarin region. Areas with maximum fish density usually have a temperature range of 2.4–4.0°C in near-bottom water layers; they are observed in the same localities, with some interannual variation: in the middle shelf, with depths of 50–160 m southwest of Cape Navarin to Cape Khaiidin and between the Dezhneva Bay and Expeditsii Bay, and in waters of the continental slope adjacent to the first area, with depths over 270 m. The accumulations on the shelf mainly consist of such commercial species as the Alaska pollock Theragra chalcogramma, Pacific cod Gadus macrocephalus, saffron cod Eleginus gracilis, northern rock sole Lepidopsetta polyxystra, Alaska plaice Pleuronectes quadrituberculatus, and righteye flounders of the genus Hippoglossoides (H. robustus and H. elassodon); on the continental slope, they consist mainly of the Greenland halibut Reinhardtius hippoglossoides and Pacific halibut Hippoglossus stenolepis. The recorded density of fish in the Olyutorsky-Navarin region was the highest in 2004–2005 and the lowest in 1999, 2001, and 2002. This variation was determined mainly by the interannual variation in the fishing for cods (Gadidae), which reflected the emergence of abundant generations and migration activity in fishes of this family, as well as from differences in the efficiency of fishing gear. Fishing for many species can and should be performed simultaneously; special attention should be paid to the coastal areas of the Olyutorsky-Navarin region, where considerable fish resources (such as the saffron cod, Pacific halibut, and other righteye flounders) are present.
