Posterior edge of opercle finely serrated, lower edge with strong forward- directed denticles (Ref. 231). 2 flat opercular spines (Ref. 231, 57391). Young with some dark spots on upper part of body (Ref. 231).

Adults manifest demersal behavior, inhabit coastal waters down to about 100 m depth but more common in shallow waters (Ref. 54221, 57391). Found in the littoral zone on various kinds of bottoms on estuaries, lagoons and occasionally rivers. They enter coastal waters and river mouths in summer, but migrate offshore in colder weather and occur in deep water during winter in the northern range. Young fish form school, but adults appear to be less gregarious (Ref. 9987). Feed chiefly on shrimps and mollusks, also on fishes (Ref. 5990). Juveniles feed on invertebrates, taking increasingly more fish with age. Adults piscivorous . (Ref. 59043). Spawn in batches (Ref. 51846). Spawning takes place in the spring near the British Isles, and earlier in its southern range. Eggs are pelagic (Ref. 35388). Marketed fresh or smoked (Ref. 9987). Highly sought by sport fishermen (Ref. 30578).
底栖行为, 居住于沿岸水域向下至大约 100 公尺深但是较常见于浅水域.(参考文献 54221) 在河口上的各种不同类型的底部上栖息于海滨的区域, 舄湖与偶然地河。 在夏天进入沿岸水域与河口, 但是移动较寒冷的天气的外海而且在北方的范围中在冬天期间出现于深水域中。 幼鱼形成鱼群，但是成鱼状似比较不群居.(参考文献 9987) 主要捕食虾与软件动物，也吃鱼。 (参考文献 5990) 在市场上销售新鲜或熏制。 (参考文献 9987) 深受运动钓鱼者企求。 (参考文献 30578) 产卵，发生于春天在英國人的附近成為島嶼, 與比較早的在它的南方範圍中。 卵是大洋性的。 (參考文獻 35388)
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Spawn in groups. Eggs are pelagic. In the Mediterranean, first sexual maturity occurs generally between 2 and 4 years of age while in the Atlantic sexual maturity happens a little later (males between 4-7 years and females between 5-8 years). Spawning happens just once a year and it tends to be in winter, although in southern areas it can occur in spring. Eggs have 1-2 fat drops that fuse about 12 hours after laying. Embryo development lasts about three days at 13-14°C and larval development about 40 days at 19°C. Egg size 1.1-1.5 mm, larval length at hatching 3 mm.東大西洋: 挪威到摩洛哥, 加納利群島與塞內加爾。 記錄來自冰島了。 (參考文獻 12462) 也已知來自地中海與黑海。
