North America: New Brunswick in Canada to South Carolina in the USA; Great Lakes, Hudson Bay and upper Mississippi basins from Quebec and New York west to southeast Manitoba and North Dakota, and south to north Kentucky and Missouri. Widely introduced. Several countries report adverse ecological impact after introduction.
Inhabits vegetated lakes and ponds, as well as vegetated pools of creeks and small rivers (Ref. 5723). An introduced species in Europe which avoids swift waters and occurs in estuaries with a salinity up to 18.2 ppt (Ref. 59043). Feeds on small fishes and other vertebrates (Ref. 1998), as well as fish eggs (Ref. 2058). Reported in Europe to prey on a wide variety of invertebrates (Ref. 59043).
