Usually bluish olive, gray or black on the upper part of the body, becoming white below; dark spots usually scattered along the sides; older males dark in color, the head looking very wide when seen from the top; long barbels surrounding the mouth and the tail deeply forked (Ref. 44091).
Inhabits lakes and deep pools and runs over sand or rocks in small to large rivers (Ref. 86798). Adults occur in rivers and streams and prefer clean, well oxygenated water (Ref. 9988), but also in ponds and reservoirs (Ref. 10294, 44091). Recorded as having been or being farmed in rice fields (Ref. 119549). Feeds primarily on small fish, crustaceans (e.g. crayfish), clams and snails; also on aquatic insects and small mammals (Ref. 9669, 10294, 44091). Marketed fresh, smoked and frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). Albino form common in the aquarium trade (Ref. 13371).
栖息于河川与溪流而且偏爱乾净的, 溶氧量高的水 (参考文献 9988), 也在池塘与水库.(参考文献 44091) 主要捕食小鱼，甲壳动物 (例如小龙虾) ，蛤与蜗牛; 也吃水生昆虫与小的哺乳动物。 (参考文献 44091) 在市场上销售生鲜、烟熏与冷冻; 清蒸,油炸,火烤, 煮沸, 微波了而且烧烤了.(参考文献 9988) 白化形式常见于水族贸易。 (参考文献 13371)
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.北美洲: 到加拿大南部與墨西哥北部的美國的中央流域。 貿易在德國限制 (Anl。3 BArtSchV).
