توصيف مختصر كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري

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).

زيست شناسي     واژه نامه (بعنوان مثال 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).

Life cycle and mating behavior Maturities | تولید مثل | Spawnings | Egg(s) | Fecundities | توزاد ( لارو)

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.
