Short description Bestämningsnycklar | Morfologi | Morfometri

Caudal fin emarginate in juveniles.

Juveniles live in a specific inshore habitat until they reach 18 cm, thereafter it lives in the superficial pelagic zone; exclusively pelagic predator, feeding on clupeids and to a lesser extent on Luciolates; highly susceptible to intensive fishing (Ref. 2216). Oviparous (Ref. 205). Juveniles often found near river mouths, but not in the rivers (Ref. 36901). Also caught using handlines (Ref. 4967).

Life cycle and mating behavior Maturities | Reproduktion | Spawnings | Egg(s) | Fecundities | Larver

May breed in areas with plants (Ref. 205). Distinct pairing during breeding (Ref. 205). Oviparous (Ref. 205).
