生物学特性     字汇 (例如 epibenthic)

Adults inhabit coastal waters, estuaries and lagoons, penetrating into freshwater; usually at depths less than 20 m (Ref. 3713). Feed on fishes (Gobiidae, Gerreidae, Engraulidae) and crustaceans (shrimps and crabs) (Ref. 35237). Mature individuals congregate at mouths of passes and rivers during the spawning season, May through September (Ref. 3713). Seasonal movements into freshwater occur but poorly understood (Ref. 3713). Marketed fresh (Ref. 5712). Valued game fish and an excellent food fish (Ref. 26938). The world record for hook and line is a 53-lb., 10 ounce fish caught at Parismina Ranch, Costa Rica (Ref. 13442).

栖息于沿岸水域, 河口与泻湖, 进入淡水之内; 通常在深度小于 20 公尺.(参考文献 3713) 吃鱼 (鰕虎鱼科，银鲈科 , 科) 与甲壳动物 (虾与螃蟹) 。 (参考文献 35237) 在产卵季节的时候在海峡口与河聚集, 可以整九月.(参考文献 3713) 进入淡水之内的季节性移动出现但是贫乏地了解.(参考文献 3713) 在市场上销售生鲜地了。 (参考文献 5712) 价值的游钓鱼类与一个优良的食用鱼.(参考文献 26938) 给一支钓的世界纪录是 53 磅。,10 盎司鱼捕获于 Parismina 大农场，哥斯大黎加了。 (参考文献 13442)
