Biology     Glossary (e.g. epibenthic)

Found in estuarine habitats with slightly reduced salinities and in areas where surface temperature range between 20° and 30°C, forming schools of equally sized individuals. Batch spawning is believed to extend from March through September (Ref. 9684). Feeds chiefly on microzooplankton with a high phytoplankton component. Marketed fresh, frozen, canned, dried salted and smoked.
