Description

The bonga shad is a clupeid of the family Clupeidae reaching about 46 cm. The compressed, fairly deep body has keeled belly scutes, golden tints and a faint dark spot behind the gill cover; the upper jaw bears a notch into which the tip of the lower jaw fits. The species is a filter feeder that sieves phytoplankton, chiefly diatoms, from the water with very fine gill rakers. It lives pelagically in shallow coastal waters, lagoons and estuaries of the eastern central Atlantic and sometimes enters freshwater rivers. The bonga shad forms large schools and is a very important and sought-after food fish in West Africa.
