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.

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.
