Ecology of Micropterus salmoides
Main Ref. Turner, J.L., 1966
Remarks Inhabit streams and lakes (Ref. 10294). Survive in the cool areas of some highland dams where they were introduced as sporting fish (Ref. 4967). Introduced in Europe since 1883. Prefer warm waters of 27°C (Ref. 11273) and occur in small shallow lakes (maximum depth of 6 m) or in shallow bays of big lakes. Rarely found in big rivers (Ref. 11243). Juveniles feed mainly on invertebrates, plankton and insect larvae (Ref. 10294, 11243); individuals from 5 cm TL become almost exclusively piscivores but also feed on frogs and some crustaceans. These are dusk and dawn feeders, feeding in schools chasing their prey near the surface and in zones with vegetation. Feeding slows down in winter and during spawning (Ref. 11243). Preyed upon by herons, bitterns, and kingfishers (Ref. 1998).
