Distribution and habitat
Sebastes ratrelliger is found in the eastern Pacific Ocean along the western coast of North America. It ranges from Cedros Island in Baja California[5] north as far as Ucluelet on Vancouver Island in British Columbia, although they are most abundant from northern California south.[7] It is a demersal fish found at depths down to 46 m (151 ft) but are typically found in less than 15 m (49 ft).[1] This is a shallow water species in which the juveniles and adults occur on hard structures, such as reefs, and among kelp beds where there are crevices they can use as shelters.[7]
Biology
Sebastes rastreliger is a predatory species feeding on crustaceans and smaller fishes such as juvenile surfperches and midshipmen (Porichthys spp).[7] They have been found to live up to 23 years with the males and females growing at roughly the same rate and have similar maximum sizes. In southern California half the fish are sexually mature at 4 years old and a length of 23.5 cm (9.3 in), and all are sexually mature at 5 years old and at a length of 27.5 cm (10.8 in). The females bear between 80,000 and 760,000 eggs in a season and the larvae are all released simultaneously. In southerbn California breeding occurs between January and March with peaking in January. Newborn larvae are planktonic have standard lengths between 4.25 and 4.5 mm (0.167 and 0.177 in) and settle on the substrate when they reach 2.7 cm (1.1 in), appearing in shallow waters and tidal pools between spring and summer.[8] The larvae do not disperse far and the adults aree sedentary, remaining within their home range for most of their life,[6]
Fisheries
Sebastes rastrelliger is an important species in commercial and recreational fisheries.[7]
