Biology     Glossary (e.g. epibenthic)

Predominantly neritic species avoiding very turbid waters and areas with reduced salinity such as estuaries. May form schools of varying size. Feeds on a variety of fishes, cephalopods, and crustaceans, particularly stomatopod larvae and prawns (Ref. 9684). Marketed mainly fresh and dried salted (Ref. 9684), but also smoked, canned and frozen (Ref. 9987).
