ABSTRACT

African catfish culture technology is in the phase of experimentation in Pakistan. The present study was conducted to develop a brood stock and to study its reproductive performance and breeding success in culture system of Pakistan. For the brood stock development, one thousand fingerlings of Clarias gariepinus were stocked in earthen ponds. The shooter fish were separated and kept in separate ponds of 0.04-hectare area. The mature 100 males and 100 female brooders fish were selected on basis of morphometric characters. Monthly gonadosomatic index of male and female Clarias gariepinus was lower in male as compare to female fish. Milt volume of male African catfish was directly related to its body weight. It was seen that by increasing weight of male African catfish the milt volume, motility, motility duration and sperm concentration also increased. The relationship of fecundity with total weight was linear and positive, while reverse relationship was observed between absolute fecundity and total weight. The highest percentage of fertilization and hatchability rate was found as 88.74±4.23 and 80.76±3.42, respectively. Which were recorded in females having body weight between 800-900g, respectively. The lowest percentage of fertilization and hatchability rate was 65.23±3.26 and 45.11±2.76 recorded in females having body weight of 1200-1800g, respectively. It was concluded that African catfish can easily be bred through induce breeding in the local environment. In addition, the breeding season of African catfish start in May and ends up in September. A female fish of about 1 kg gave good results in the terms of fertilization rate (%) hatching rate (%) and a handsome number of hatchlings was obtained by the artificial breeding.
