Occurs usually in shallow coastal waters over sand and sandy mud bottoms. Juveniles are euryhaline. During summer the fish move to their nursery and feeding grounds in river estuaries. Feeds mainly on crustaceans and fishes. Oviparous, with high fecundity (Ref. 54406). The species leave estuaries during the fall when water temperatures decrease, but are also known to overwinter in these areas. It has been reported that the fish cease feeding and die when the water temperature reaches 7.9 deg C and 3.3 deg. C, respectively (Ref. 122657). Utilized fresh and frozen; eaten steamed, pan-fried, broiled, microwaved and baked (Ref. 9988).
通常生活在沙子与沙泥底上的沿岸浅水区。 稚鱼是广盐性。 鱼在河口中移动到他们的育幼与觅食场夏天时。 主要吃甲壳动物和鱼类。 卵生的, 有高的孕卵数。 (参考文献 54406) 生鲜使用与冷冻; 清蒸, 油锅炸的, 火烤了, 微波了而且烧烤了.(参考文献 9988)
