Occurs in sand-bottomed and mud-bottomed pools and backwaters of creeks and small to large rivers, and lakes and ponds. Often found in turbid water (Ref. 5723, 10294). Adult feeds on forage fishes such as shad (Ref. 10294). Younger crappie consumes small invertebrates, including microcrustaceans and small insects (Ref. 10294).
