Remarks Occurs in clear vegetated lakes, quiet pools and backwaters of creeks and small to large rivers (Ref. 5723, 10294). Usually solitary and highly territorial. Enters brackish water in the Baltic. Adult feeds mainly on fishes, but at times feeds heavily on frogs and crayfish (Ref. 27547). Cannibalistic as juveniles (Ref. 30578). Eggs and young are preyed upon by fishes, aquatic insect larvae, birds, and aquatic mammals (Ref. 1998). Does not generally undertake long migrations, but a few may move considerable distances (Ref. 27547).
