This study determined the optimum protein and digestible energy levels for Clarias gariepinus fingerlings fed local feed. Sixteen diets of four digestible energy (DE) level (2400, 2600, 2800 and 3000 Kcal/Kg) each at four crude proteins (CP) levels (25, 30, 35 and 40%) were formulated and fed to the fingerlings for 70days. The result showed that the highest final weight of fish (34.24g) was obtained in the 35 %CP (DE of 2400 kcal/kg).

This study determined the growth response of Clarias gariepinus fingerlings fed ground toasted Cassia fistula (CF) seed. Partial replacement of soyabean in the diet with varying levels of Cassia fistula seed meal at 0%, 10%, 20%, 30%, 40% and 50% were carried out for 70 days. The fishes were fed twice daily to satiation. One hundred and twenty-six (126) fingerlings with an initial mean weight of 1.68±0.76 g were allotted at random to aquaria tanks of 25 L size. A total of 18 tanks was used with each tank containing seven fishes.
