- Abstract
This study seeks to compare the growth of two African catfishes and their hybrid fed with commercial diet. Fingerling of Clarias gariepinus Heterobranchus bidorsalis and hybrid H. bidorsalis x C. gariepinus (Heteroclarias) were obtained from homogeneous breeding. Fingerlings with mean weight 1.11?0.01 were stocked in triplicate plastic tanks for this study. The study observed that C. gariepinus had the highest Mean Final weight (7.75), Mean weight gain (6.65), Specific growth rate (2.10), Feed conversion efficiency (53.2%) and Protein efficiency ratio (6.23) compared with H. bidorsalis and Heteroclarias which had lower growth values (p<0.05), however survival rate were the same across the species. Similarly carcass moisture and lipid content were observed to be higher in C. gariepinus compared to the others, However, Ash, fiber and NFE content of the hybrid were higher compared to pure breeds (P<0.05). Also, significantly higher carcass protein was recorded in H. bidorsalis compared to the others, while higher lipid where observed in C. gariepinus. It is concluded that at early stage of life, C. gariepinus exhibit faster growth rate.
