Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 18.7, range 17 - 23 cm
Max length : 90.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 4781); common length : 50.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 4781); 最大體重: 11.6 kg (Ref. 40637)
Generally found in hard bottoms (rocks and rubble), the older individuals in the deeper part of the range, the young in inshore areas. Feed mainly on bivalves and also on crustaceans and fish. Sexual maturity at 2 years old. Spawning migration occurs parallel to the coast with intermittent spawning between spring and autumn over soft bottoms in shallow waters (Ref. 3688).
棲息於堅硬的底部 (岩石與碎石), 那較年長的個體在範圍的較深的部份中, 幼魚在近海區域中。 主要吃二枚貝以及在甲殼類動物和魚類上。 性成熟在 2 歲。 產卵遷移平行於海岸具有在軟質底部上的春天與秋天之間斷續的產卵在淺水區中.(參考文獻 3688)
