Spatial distribution and dynamics of catches of Sebastes glaucus, S.iracundus, and S. polyspinis in Pacific waters off the Kuril Islandsand Kamchatka

摘要

Based on studies of the years 1992-2001, quantitative indices characterizing the occurrence of three rare or little-studied species of rockfish (Sebastes glaucus, S. iracundus, and S. polyspinis) in Pacific waters off the northern Kuril Islands and southeastern Kamchatka are provided. Specific features of distribution (spatial, vertical, and dependence on near-bottom temperatures) are considered. New data on the diurnal, seasonal, and multiyear dynamics of their catches and occurrence, as well as on the length and weight of the body, sex ratio, and sexual dimorphism in the amount and intensity of feeding are cited.
