Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 13 - 21; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 12 - 23. Body moderately slender, quite strongly compressed, belly sharply keeled. The bright silver stripe along the flank distinguishes it from all similar clupeids in the area. Hind border of gill opening evenly rounded (with two fleshy outgrowths in Harengula and Opisthonema, the latter with a filamentous last dorsal fin ray).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
A coastal-pelagic species that forms dense schools in beaches, lagoons and estuaries (Ref. 9291). Tolerates brackish and fresh waters (Ref. 9291). Feeds on plankton, especially on small crustaceans and fish larvae (Ref. 9291). Processed into oil and fishmeal (Ref. 37955).
