Vomerine teeth only anteriorly (Ref. 231), in a crescentic band (Ref. 231, 57391). Scales on interorbital space cycloid (Ref. 57391). 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).
鰓蓋的後緣細鋸齒狀的, 下緣有強的朝向前的細齒。 2根平坦的鰓蓋棘。 嘴一般可伸出。 在身體的上半部上幼魚有一些深色斑點。 頭部有圓形的鱗片上方。 犛骨齒只有前面地, 在一條新月形的條紋中。
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).
成魚被棲息於沿岸水域的顯然的底棲行為向下至大約 100 公尺深但是較常見於淺水域.(參考文獻 54221) 他們在河口上的各種不同類型的底部上被發現於海濱的區域, 潟湖與偶然地河。 他們在夏天進入沿岸水域與河口, 但是移動較寒冷的天氣的外海而且在北方的範圍中在冬天期間出現在深水域。 幼魚形成魚群，但是成魚狀似比較不群居.(參考文獻 9987) 主要地吃吃蝦子與軟體動物，也吃魚。 (參考文獻 5990) 產卵於一批中。 (參考文獻 51846) 產卵，發生於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) 在市場上銷售新鮮或燻製。 (參考文獻 9987) 深受運動釣魚者企求。 (參考文獻 30578)
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
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。
