Ecology Summary - Micropterus dolomieu

Language:

Main Ref.	Waters, T.F., J.P. Kaehler, T.J. Polomis and T.J. Kwak, 1993
Remarks	Inhabits shallow rocky areas of lakes, clear and gravel-bottom runs and flowing pools of rivers, cool flowing streams and reservoirs fed by such streams. Young feed on plankton and immature aquatic insects while adults take in crayfish, fishes, and aquatic and terrestrial insects (Refs. 1998; 44091). Sometime cannibalistic (Ref. 30578). Preyed upon by fishes and turtles (Ref. 1998). Feeds on fish and benthic invertebrates (Ref. 26273).
