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).
通常发现于邻近海藻床, 浅水区而且到大约 50 公尺但是大部份从 2.4-21 公尺。 在水团各处发现。 大的标本通常出现在较深的水域。 稚鱼吃底栖的无脊椎动物;(尤其甲壳动物) 成鱼吃鱼与头足类动物。 (参考文献 9342) 两者的稚鱼与成鱼可能吃浮游生物 , 当丰富的时候。 (参考文献 9342) 大洋性产卵鱼.(参考文献 56049) 也用延绳钓捕获。 (参考文献 9342) 优良的食用鱼与一个重要的游钓鱼类.(参考文献 9342)
