Régime alimentaire de la phase lagunaire de Elops lacerta (C.V. 1846)

Elops lacerta is a juvenil's predator of all the fish species living in the same biotope. its preys follow three systematic orders: 1 - Fishes: they are the most important in the stomachal contents of Elops lacerta, and are dominated by clupeidae, mainly by Ethmalosa fimbriata; 2 - Shrimps: mainly the Peneidae, are not very important; 3 - Molluscs: they are the less important preys and are represented by only one Pelecypoda family: the Corbulidae. This earlier predator feeds rather at night than during the day. It has neither preferential prey nor apparent seasonal variations in its food habits.
