Short description

Dorsal spines (total): 8 - 11; Dorsal soft rays (total): 12; Anal spines: 0; Anal soft rays: 12. Snout pointed. Maxilla covered by lachrymal bone but extending nearly to end of lacrimae. Interpelvic process small and single. Swim bladder present. Vertebrae 13 precaudal plus 18 caudal, total 31. Bristles on longest gill raker about 150 on one side in specimens of 12.7 cm, 210 in specimens of 16 cm, and 240 in specimens of 19 cm fork length. Anal spine rudimentary.

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.

IUCN Red List Status (Ref. 115185)
