The crappies are a genus, Pomoxis, of North American freshwater fish in the sunfish family Centrarchidae. Both species in this genus are popular game fish.
There are currently two recognized species in this genus: Pomoxis annularis (White crappie) and Pomoxis nigromaculatus (Black crappie).
Both species of crappie as adults feed predominantly on smaller species, including the young of their own predators (which include the northern pike, muskellunge, and walleye). They have diverse diets, however, including zooplankton, insects, and crustaceans. By day, crappie tend to be less active and to concentrate around weed beds or submerged objects, such as logs and boulders; they feed especially at dawn and dusk, moving then into open water or approaching the shore.
