Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 16-19; Anal spines: 0; Anal soft rays: 19 - 23. Upper jaw with distinct median notch, into which tip of lower jaw fits. Lower gill rakers long, fine and numerous, about 3 times as long as gill filaments; upper gill rakers bent sharply upward, V-shaped. Caudal fin deep chrome, tips long and pointed. A faint dark spot behind gill cover (sometimes followed by others); dorsal fin tip black; golden tints on body. Scute: 16-19 prepelvic, 10-13 post. Scales in lateral series 37-42.

Biology     Glossary (e.g. epibenthic)

Occurs in inshore waters, lagoons and more than 300 km up rivers (e.g. Gambia River). Feeds by filtering phytoplankton, chiefly diatoms. Breeds throughout the year in waters of salinities 3.5-38 ppt, but with peaks in at least some areas. Spawns in the sea, in estuaries and rivers. Feeds on phytoplankton, chiefly diatoms. Marketed fresh, also smoked and dried.

IUCN Red List Status (Ref. 90363)
