Fairly common in marine and fresh waters (Ref. 4180); found in shallow waters; common in estuaries; may enter lower reaches of rivers. Can tolerate fresh water only within a narrow temperature (23-26°C). Feeds mainly at night on crustaceans, but also takes small fishes, fish eggs and larvae in estuaries (Ref. 7248). Marketed dried, salted and fresh (Ref.97399).
