North America: St. Lawrence-Great Lakes, Hudson Bay (Red River drainage), and Missouri-Mississippi river basins from southern Quebec to southern Manitoba and Montana south to Gulf. Possibly native on Atlantic and Gulf slopes from Susquehanna River to Neuse River, and from Savannah River to Lake Okeechobee, Florida, and west to northern Mexico and eastern New Mexico.

Biologie     Verklarende woordenlijst (bv. epibenthic)

Adults inhabit lakes and deep pools and runs over sand or rocks in small to large rivers (Ref. 86798). They occur in rivers and streams and prefer clean, well oxygenated water (Ref. 9988), but also in ponds and reservoirs (Ref. 10294, 44091). Food consists primarily of small fish, crustaceans (e.g. crayfish), clams and snails; also on aquatic insects and small mammals (Ref. 9669, 10294, 44091). Recorded as having been or being farmed in rice fields (Ref. 119549). Marketed fresh, smoked and frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). Albino form common in the aquarium trade (Ref. 13371).

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

Spawning happens, depending on latitude, during the months of April-July, with temperatures between 27-28°C. Females lay their egges on a hole dug on sandy grounds. Incubation lasts 3-8 days, and larval development between 12-16 days, depending on temperature. The pair builds a depression in the ground, which is guarded by the male (Ref. 1672). Channel catfish requires cool water and short day lengths during the winter months for proper egg development; an egg mass can contain up to 20,000 eggs (Ref. 44091). Sexual maturity is reached at 2-3 years.
