A study was conducted to observe the breeding and larval rearing of Asian Catfish, Clarias batrachus. fed with live and/or artificial feed for 21 days in an indoor hatchery. The brooders of . C. batrachus (Av. wt of female 160 ± 10.5 g; Av. wt of male 120 ± 6.75 g) were procured from outside ponds and stocked in a pond near the experiment sit age. Catfish have an elaborate breeding behavior and the male usually incubates the eggs. The period of incuba-tion (hatching time) of catfish eggs depends on water temperature. Eggs hatch in four to ten days at temperatures between 21 and 27°C (70-81°F); at optimum spawning and incubation temperatures (25°-27°C), embryos hatch in 4 to. The whole process of catfish breeding starts with identification of sexes and age of broodstock to be used. The average age for any breeding stock should be between 2-3 years to get healthy and good performing fingerlings. The male and female of the African catfish are similar in build yet different. The male has a distinct sexual papilla.

Some breeders, in order to gain profit faster and rush the process, usually hatch their fishes with fishes that are not mature enough, or sell the catfish juveniles with poor conditions. This can result in weak catfish and they will not thrive. For any successful catfish breeding and genetic improvement programme, there is the need for: Identification of the parent stock (i.e. external features of Heterobranchus and Clarias species); Sexing to identify male and female broodstock; Differentiation of hybrids from the putative parent stock. Heterobranchus and Clarias speices Catfish farming is an important agricultural industry in the United States, with more than 60,000 acres of water devoted to catfish pro­ duction.
