The Pacific ocean perch (Sebastes alutus), also known as the Pacific rockfish, Rose fish, Red bream or Red perch has a wide distribution in the North Pacific from southern California around the Pacific rim to northern Honshū, Japan, including the Bering Sea. The species appears to be most abundant in northern British Columbia, the Gulf of Alaska, and the Aleutian Islands. Adults are found primarily offshore on the outer continental shelf and the upper continental slope in depths 150–420 m. Seasonal differences in depth distribution have been noted by many investigators. In the summer, adults inhabit shallower depths, especially those between 150 and 300 m. In the fall, the fish apparently migrate farther offshore to depths of ~300–420 m. They reside in these deeper depths until about May, when they return to their shallower summer distribution.
