Max length : 130 cm TL 雄魚/尚未辨別雌雄; (Ref. 1371); common length : 60.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 4645); 最大體重: 32.0 kg (Ref. 7251); 最大年齡: 25 年 (Ref. 1371)
背棘 (總數): 0; 臀棘 0. Chin barbel small. Lateral line smooth along its entire length. Body color is brownish-green dorsally, becoming only slightly paler ventrally. The lateral line pale.
An active, gregarious fish occurring inshore and offshore waters. Usually enters coastal waters in spring and returns to deeper waters in winter (Ref. 9988). Smaller fish in inshore waters feed on small crustaceans (copepods, amphipods, euphausiids) and small fish, while larger fish prey predominantly upon fishes. Spawn in batches (Ref. 51846). Utilized fresh, dried or salted, smoked, canned and frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988).
