Intensive Production of the African Catfish Clarias gariepinus (Burchell, 1822) Fingerlings Using Local Materials in Recycled Water | Chapter 06 | Advances in Agriculture and Fisheries Research Vol. 1
This study was conducted with the aim of producing intensively and cheaply the fry of the African catfish Clarias gariepinus at the Akak Essatolo Fish Farm in Ebolowa, South Region Cameroon. For that, 10 broodstock of C. gariepinus, were used for the artificial reproduction. Pituitary extracts and Ovaprim hormones were used to induce oocytes maturation on females. Eggs were obtained by abdominal pressure of the female. Wicks (or Local raffia fibbers (Raphia regalis)) and mesh frame were used as incubators of fertilized eggs. 12 experimental batches each consisting of 50 g of fertilized eggs were spread in triplicates on both types of incubators previously arranged in closed-circuit tanks. Fertilized eggs were enumerated by direct observation. At the end of the hatching (D0) and of vitelline resorption (D3), larvae of each experimental lot were counted. The results obtained indicate that: Similar (P=.05) absolute and relative fecundities used were recorded in all treatments. Female e...
