Occurs in lakes, pools, backwaters, and runs of medium to large rivers. Frequently found in clear water, usually near brush (Ref.
). Prefers large, shallow lakes with high turbidity (Ref.
). Rarely found in brackish waters (Ref.
). Feeds at night, mainly on insects and fishes (prefers yellow perch and freshwater drum but will take any fish available) but feeds on crayfish, snails, frogs, mudpuppies, and small mammals when fish and insects are scarce (Ref.
). Although not widely farmed commercially for consumption, large numbers are hatched and raised for stocking lakes for game fishing (Ref.
). Utilized fresh or frozen; eaten pan-fried, broiled, microwaved and baked (Ref.
Spawning occurs in small groups (a larger female and two smaller males or two females and up to six males) that engage in chasing, circular swimming, and fin erection. The group then ascends to shallow water, females roll on their side, and eggs and sperm are released. Deposition of eggs usually occurs in a single night (Ref.
). Larvae pelagic (Ref.
