Abstract

Optimum feeding rate, energy and protein maintenance requirements were reported in the fingerling of Clarias gariepinus (Burchell 1822), fed with purified diet (45% C.P.; 360.5 kcal/100g energy) at 0-10% Body Weight day-1. A linear increase (r = 0.99) was observed in daily average growth increment up to a ration level of 8% Bw. day-1 but maximum conversion efficiencies were obtained at 4% Bw. day-1, corresponding to protein and energy intakes of 0.05g/fish day-1 and 0.39 kcal/fish day-1 respectively. The study indicates that a ration level of 4% Bw day-1 is optimum for this species at 25±1° C. Poor Food Conversion Ratio and daily average growth increment obtained at a ration level of 2% Bw day-1 suggested that this level approximated the maintenance requirements of the fish. Body moisture, fat and ash contents were significantly (P<0.05) affected by ration levels whereas variations in protein were insignificant (P>0.05).
