簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 0; 背的軟條 (總數): 78-92; 臀棘 0; 臀鰭軟條: 58 - 69; 脊椎骨: 39 - 42. Dorsal origin above eye. Caudal rounded. Pectoral small, bluntly pointed.
背鰭起點眼睛上方。 尾鰭圓的。 胸的小, 頓尖的。
Common in shallow water on soft, silty bottom. Moves into shallow water in summer and to deeper water in winter (Ref. 6885). Spawning adults exhibit north-south migrations (Ref. 6885). Feeds on chaetopod marine worms, young herring, shrimps, and sand dollars (Ref. 6885). A tasty food fish, sometimes marketed (Ref. 2850). Also used for mink food (Ref. 2850).
在柔軟上常見於淺水區, 淤泥的底部。 在夏天與到較深的水域冬天時移入淺水區。 (參考文獻 6885) 產卵的成魚展現南北迴游。 (參考文獻 6885) 吃 chaetopod 海洋的蠕蟲,幼魚鯡魚,蝦與沙子元。 (參考文獻 6885) 一個好吃的食用魚, 有時在市場上銷售。 (參考文獻 2850) 也用來貂食物。 (參考文獻 2850)

營養階層 (Ref.
69278): 3.6 ±0.54 se; based on food items.
Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
