Food Comments
Eats mainly insect larvae, crustaceans, and occasionally small fishes. Smaller individuals apparently depend on crustaceans and oligochaetes; larger fishes rely more on insects. Feeds at night on bottom and among aquatic plants.
Reproduction Comments
Usually spawns in June and July. Most individuals sexually mature in 2nd year, with few living beyond 3rd year (Lee et al. 1980).

Global Range
Atlantic and Gulf Slope drainages from New Hampshire to Nueces River, Texas; St. Lawrence-Great Lakes, Hudson Bay (Red River), and Mississippi River basins from southern Quebec to southern Saskatchewan, and south to the Gulf; absent from Appalachian and Ozark highlands; introduced into Snake River, Idaho and Oregon; presumably introduced into Massachusetts and New Hampshire; usually common (Page and Burr 1991).
