Additions to the Occurrence of Two Rare Species of Rockfish of the Genus Sebastes (Sebastidae) in Pacific Waters Off the Kuril Islands
摘要
Abstract
New data are presented on the occurrence of the northern rockfish Sebastes polyspinis and angry rockfish S. iracundus off the Kuril Islands. It is shown that these species are very rare in Pacific waters off the Middle Kuril Islands. The catches of northern rockfish in this area indicate a southward expansion of its geographic distribution within the Northwestern Pacific. The northern periphery of the range of angry rockfish (47°–49° N) is presumably not a sterile eviction zone, and the full life cycle of its individuals can occur there.
