Biology     Glossary (e.g. epibenthic)

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).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Pelagic spawner (Ref. 56049). Spawning aggregations are a significant component of the reproductive behavior of this species (Ref. 59326). Also Ref. 103751.
