Short description Morphology | Morphometrics

Dorsal spines (total): 8 - 11; Dorsal soft rays (total): 12; Anal spines: 0; Anal soft rays: 12; Vertebrae: 31. This species is distinguished by the following characters: body very deep, its depth at posterior margin of opercle 3.7-4.3 times in fork length; head equal to or less than body depth; maxilla covered by lacrimal bone but extending nearly to end of lacrimal; gill rakers very long, visible when mouth is opened, 30-48 on lower limb of first gill arch; numerous bristles on longest gill raker, about 150 on one side in specimens of 12.7 cm, 210 in specimens of 16 cm, and 240 at 19 cm fork length; intestine very long, 3.2-3.6 times fork length; snout pointed; swim bladder present; vertebrae 13 + 18 = 31; interpelvic process small and single; anal spine rudimentary. Colour of spinous dorsal fin yellowish with a black edge, pectoral and pelvic fins dusky, other fins yellowish (Ref. 168, 9684).

Biology     Glossary (e.g. epibenthic)

An epipelagic, neritic species that tolerates slightly reduced salinities in estuarine habitats and in areas where surface temperature range between 20° and 30°C. It forms schools of equally sized individuals. Batch spawning is believed to extend from March through September. Feeds chiefly on microzooplankton with a high phytoplankton component. Marketed fresh, frozen, canned, dried salted and smoked (Ref. 168, 9684).
