简单描述 检索表 | 型态特徵 | 形态测量图

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).
通常蓝色的橄榄色,灰色的或黑色的在身体的上半部上, 变成腹面白色; 深色斑点通常分散的沿着侧边; 年长的雄性黑的颜色, 头部看起来非常宽当从顶端见到; 长的触须环绕嘴巴周围与尾部分岔很深.(参考文献 44091)

生物学特性     字汇 (例如 epibenthic)

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)

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼

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).
