Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; depth range 1 - 61 m (Ref. 96339). Subtropical; 48°N - 23°N, 126°W - 109°W

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 72.0 cm TL male/unsexed; (Ref. 2850); max. published weight: 7.0 kg (Ref. 9342); max. reported age: 34 years (Ref. 56049)
Usually found in or near kelp beds, shallow water and to about 50 m but mostly from 2.4-21m . Found throughout water column. Large specimens usually occur in deeper water. Juveniles feed on benthic invertebrates (especially crustaceans); adults feed on fishes and cephalopods (Ref.9342). Both juveniles and adults may feed on plankton when abundant (Ref.9342). Pelagic spawners (Ref. 56049). Also caught with troll lines (Ref. 9342). Excellent food fish and an important game fish (Ref. 9342).
Pelagic spawner (Ref. 56049). Aggregation spawning is a significant component of the reproductive behavior of this species (Ref. 59326). Also Ref. 103751.
