生物学特性     字汇 (例如 epibenthic)

Adults frequently in channels or holes, over sandy flats, around reefs, and at times over mud bottoms; usually solitary or in small schools; smaller fish tolerate brackish water. Spawn offshore (Ref. 26938). During the summer, juveniles are found in large schools especially in the surf zone along sandy beaches. Adults feed on mollusks, crabs, shrimps, and small fishes; juveniles on benthic invertebrates. Excellent food fish (Ref. 9626). Highly esteemed game fish caught on light tackle (Ref. 26938).

时常在峡道或洞的成鱼, 在沙平台之上, 礁的周围, 偶而在泥底之上; 通常独居性或形成小群鱼群; 较小的鱼容忍半淡咸水。 产卵外海。 (参考文献 26938) 在夏天期间,稚鱼在海浪区中尤其被发现于大群鱼群沿着沙滩。 成鱼吃软件动物,螃蟹,虾与小鱼; 稚鱼在底栖的无脊椎动物上。 优良的食用鱼.(参考文献 9626) 深受喜爱的游钓鱼类在轻型渔具上面捕获了。 (参考文献 26938)
