Biologie     Verklarende woordenlijst (bv. epibenthic)

Adults occur in lakes, pools, backwaters, and runs of medium to large rivers. Frequently found in clear water, usually near brush (Ref. 86798). They prefer large, shallow lakes with high turbidity (Ref. 9988, 10294). Rarely found in brackish waters (Ref. 1998). They feed at night, mainly on insects and fishes (with preference for yellow perch and freshwater drum but will take any fish available) also feed on crayfish, snails, frogs, mudpuppies, and small mammals when fish and insects are scarce (Ref. 1998). Although not widely farmed commercially for consumption, large numbers are hatched and raised for stocking lakes for game fishing (Ref. 9988). Utilized fresh or frozen; eaten pan-fried, broiled, microwaved and baked (Ref. 9988).

Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven

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. 1998). Larvae pelagic (Ref. 7471).
