Biology     Glossary (e.g. epibenthic)

Found on sandy and muddy bottoms of coastal waters (Ref. 5213, 48635). Frequently in estuaries, juveniles have been taken in freshwater. Taken by handlining and seining in shallow waters and by trawling at depths to 30 m, usually less (Ref. 9790). A good food fish (Ref. 4315) that is marketed fresh (Ref. 5284). Commercially cultured in Japan. Used in Chinese medicine (Ref. 12166).
