ABSTRACT

Background: Fish farming is one of the fastest growing sub-sectors of food production and plays a key role in meeting the growing demand for fish products. The farming of Clarias gariepinus in Africa offers good prospects for fish farming, as it is probably one of the most suitable species for freshwater aquaculture. Objectives: The present study aims to understand the techniques of artificial reproduction of Clarias gariepinus and its larval monitoring adapted to a local context. Materials and Methods: Nine (9) breeders including 6 males and 3 females with respective average weights of 1124 ± 229 g and 1383 ± 461 g were selected. Each of the selected females was treated with Chorionic Gonadotropin Hormone (CGH) at doses of 0.4, 0.5 and 0.9 ml/kg of female live weight. Results: During the latency and incubation period, the average water temperature was 27.5± 1.87. The average fertilization and hatching rates were 28.33% and 23% respectively with a survival rate of 7.24%. Conclusion: The results of this research could be used as a basis for future researchers and stakeholders in the fish farming sector for the production of African catfish fingerlings.
