Abstract: The experiment was conducted to assess the performance of two commercial feeds on growth of the Dutch strain of African catfish Clarias gariepinus fingerlings for 56 days under hatchery condition in July and August, 2019 with the aim of comparing the growth response in terms of Specific Growth Rate (SGR), total weight, total length and survival rates. Sixty (60) fingerlings of C. gariepinus with average weight of 1.20±0.00g and two commercial feeds (Coppens and Skretting) with varying crude proteins were used for the study. Some water parameters analyzed indicated Temperature range of 27.35±0.03 and 27.14±0.07 for T1 and T2 respectively, pH of 7.41±0.07 and 7.41±0.03, Total Dissolved Solid (TDS) of 65.38±1.07ppm and 73.75±0.45ppm, Electrical Conductivity (EC) of 130.75±2.14µS and 147.50±0.90µS and Dissolved Oxygen (DO) of 4.44±0.04mg/L and 4.51±0.03mg/L respectively. The treatments had no significant difference in terms of Mean Weight, Specific Growth Rate (SGR), Feed Conversion Ratio (FCR), Feed Conversion Efficiency and Survival Rate (P< 0.05). In terms of mean weight, Coppens gave 4.02g while Skretting gave 4.44g. SGR showed in Coppens 2.63 and 2.64 in Skretting. Although fish fed with Coppens and Skretting both demonstrated good growth performance.
