Description:
The experiment was conduted to determine the effects of fermented clupeid paste as a substitute for fish meal in the diet of Clarias gariepinus fingerlings in hapa nets. Five (5) diets (40% crude protcein) containing fishmeal substituted with 0% (control), 25%, 50%, and 100% ferment clupeid paste were formulated. The fish fingerlings of mean weight 10.83 ~c 0.37g were fed to satiation at body weight twice per day for 30 days in hapa nets. It was observed at the end of the feeding trial that fish fed with 50% fermented paste along With 50%fish meal gave the highest final weight (FW = 19.29g) mean weight gain (MWG= 8.47g), daily growth (DGR =0.28g/day), specific growth rate (SGR 1.92%/day) and total fish production (TFP) of 1.93kg/m3. The feed conversion ratio of 1.47 was best in Diet l (Control). Growth was significantly affected (P〈0.05) and total fish production (TFP) among the treatments. Based on the results obtained from this experiment, 50% substitution level of fermnted clupeid paste with fish meal is considered the optimum inclusion level for the growth of African mud catfish, C. gariepinus fingerrlings production in hapa nets.
