Trophic Strategy

provided by Fishbase
Occurs in brackish estuaries and adjacent marine areas; penetrates freshwater (Ref. 5217). Forms moderate schools. Usually migrating from estuaries or the sea, but possibly the limnichthys of Lake Maracaibo and the amazonensis represent purely freshwater forms. In freshwater, it feeds principally on small fishes, prawns and copepods; also insect larvae. At sea, it feeds on fishes, various crustaceans, benthic organisms and zooplankton (Ref. 189). Consumed fish for more than 65% relative occurrence of its diet (Ref. 76754).
