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).
