Class:	Actinopterygii (ray-finned fishes)
FishBase name:	Bonga shad
Max. size:	45.0 cm TL (male/unsexed; Ref. 5377)
Environment:	pelagic-neritic; catadromous
Climate:	tropical; 25°N - 8°S
Global Importance:	fisheries: highly commercial; aquaculture: experimental
Resilience:	High, minimum population doubling time less than 15 months (K=0.25-0.36; tm=1; Fec=16,000)
Distribution:	Eastern Central Atlantic: Dakhla, Western Sahara to at least Lobito, Angola, corresponding to the extreme northerly and southerly limits of the 25°C isotherms throughout the year; dwarf population exist in Lake Nokoué, Benin. Cape Verde records based on erroneous type locality for Ethmalosa fimbriata by Bowdich - followed by later authors.
Diagnosis:	Dorsal spines (total): 0-0; Dorsal soft rays (total): 16-19; Anal spines: 0-0; 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:	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
Threatened:	Not Evaluated, see IUCN Red List , (Ref. 36508)
