简单描述
型态特徵 | 形态测量图
背棘 (总数): 0; 背的软条 (总数): 78-92; 臀棘 0; 臀鳍软条: 58 - 69; 脊椎骨: 39 - 42. Dorsal origin above eye. Caudal rounded. Pectoral small, bluntly pointed.
背鳍起点眼睛上方。 尾鳍圆的。 胸的小, 顿尖的。
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).
在柔软上常见于浅水区, 淤泥的底部。 在夏天与到较深的水域冬天时移入浅水区。 (参考文献 6885) 产卵的成鱼展现南北回游。 (参考文献 6885) 吃 chaetopod 海洋的蠕虫,幼鱼鲱鱼,虾与沙子元。 (参考文献 6885) 一个好吃的食用鱼, 有时在市场上销售。 (参考文献 2850) 也用来貂食物。 (参考文献 2850)
