Abstract

The effect of A. garckeana pulp meal on egg quality of Clarias gariepinus broodstocks wasinvestigated. Catfish broodstocks (mean weight 450 g) were randomly distributed into concrete tanks (2×2×1.2 m) at nine fish/tank in triplicates. Five difference (0, 50, 100,150 and 200 g/kg) concentration of A. garckeana pulp meal (AGPM) were incorporated into the broodstock diet designated as D1, D2, D3, D4 and D5, respectively. The fish were fed for 56 days. The result shows that fish fed the controlled diet had the highest number of eggs. However, among the fish feed AGMP based diet, those fed 200 g/kg of AGPM had higher (158646.0) number of eggs. D1 had the least percentage fertilization (78%). D3 had the highest hatching rate (98%), followed by D2 (96%), D4 (92%), D5 (76%) and the least D1 (62%). Survival of hatchlings after two weeks was higher in D2 (90%), followed by D3 (88%), D4 (84%), D5 (56%) and D1 (40%). There was no record of deformity of hatchlings in D2 to D4 but in D1 and D5. A. garckeana pulp meal influenced the fecundity, hatching rate and percentage survival of C. gariepinus has a potential pro-fertility property which can be harnessed in fish fingerling production.
