Atlantic Ocean: Eastern central Atlantic Ocean from Dakhla in Western Sahara to Lobito Bay in Angola (Ref. 188, 81269, 81631). Reports from Cape Verde Islands are based on an erroneous type locality for Clupea fimbriata by Bowdich (1825) which was followed by later authors (Ref. 188).

Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 16-19; Anal spines: 0; Anal soft rays: 19 - 23. Diagnosis: Ethmalosa fimbriata is distinguished from other clupeids by the presence of a median notch on the upper jaw, into which tip of lower jaw fits (Ref. 188, 81269). A faint dark spot behind gill cover, sometimes followed by others; dorsal fin tip black; caudal fin deep chrome yellow; golden tints on body (Ref. 188). Ethmalosa fimbriata resembles Sardinella aurita, Sardinella rouxi and especially Sardinella maderensis, but these are more slender, have a rounded upper jaw which is not notched and the upper gillrakers are not bent upward like an elbow (Ref. 188).

Biology     Glossary (e.g. epibenthic)

Ethmalosa fimbriata is found in coastal and estuarine regions, and sometimes also in lower courses of coastal rivers, even more than 300 km up rivers (Ref. 188, 81269, 81631). It feeds by filtering phytoplankton, chiefly diatoms (Ref. 188). It 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 in rivers (Ref. 188).
