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).
通常發現於鄰近海藻床, 淺水區而且到大約 50 公尺但是大部份從 2.4-21 公尺。 在水團各處發現。 大的標本通常出現在較深的水域。 稚魚吃底棲的無脊椎動物;(尤其甲殼動物) 成魚吃魚與頭足類動物。 (參考文獻 9342) 兩者的稚魚與成魚可能吃浮游生物 , 當豐富的時候。 (參考文獻 9342) 也用延繩釣捕獲。 (參考文獻 9342) 優良的食用魚與一個重要的遊釣魚類.(參考文獻 9342)
Pelagic spawner (Ref. 56049). Spawning aggregations are a significant component of the reproductive behavior of this species (Ref. 59326). Also Ref. 103751.東太平洋: 到墨西哥的下加利福尼亞南部的在美國在華盛頓州中的哥倫比亞河。
