Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 43.1, range 54 - 67.2 cm
Max length : 132 cm TL 雄魚/尚未辨別雌雄; (Ref. 26550); common length : 57.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 59043); 最大體重: 26.3 kg (Ref. 4699); 最大年齡: 24 年 (Ref. 59043)
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).
通常藍色的橄欖色﹐灰色的或黑色的在身體的上半部上, 變成腹面白色; 深色斑點通常分散的沿著側邊; 年長的雄性黑的顏色, 頭部看起來非常寬當從頂端見到; 長的觸鬚環繞嘴巴周圍與尾部分岔很深.(參考文獻 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).
棲息於河川與溪流而且偏愛乾淨的, 溶氧量高的水 (參考文獻 9988), 也在池塘與水庫.(參考文獻 10294,44091) 大洋底棲性魚種.(參考文獻 58302) 主要捕食小魚，甲殼動物 (例如小龍蝦) ，蛤與蝸牛; 也吃水生昆蟲與小的哺乳動物。 (參考文獻 9669,10294,44091) 在市場上銷售生鮮、煙燻與冷凍; 清蒸,油炸,火烤, 煮沸, 微波.而且燒烤..(參考文獻 9988) 白化形式常見於水族貿易。 (參考文獻 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).
