Growth performance of Clarias gariepinus juvenile reared in hapa in Kindu

Abstract

During 8 weeks, a study was conducted on the effect of incorporating fish meal on growth performance of juveniles of Clarias gariepinus reared in hapa in Kindu. In total, 74 juveniles of Clarias gariepinus were distributed in 2 hapas at the rate of 37 juveniles per hapa. The initial average weight of the fish varies between 4.04 g and 5.35 g. Two rations were formulated dosing 60 % (R1) and 50% (R2) of crude protein in which the fish meal was incorporated at a rate of 10.9 and 11.3% in each ration. Juveniles are fed for 11 weeks and 3 days and the results indicate an average specific growth rate of juveniles of 5.39 %/d with R1 versus 5.57 %/d with R2. The average final weight varies respectively from 39 g (R1) and 53 g (R2) with an average gain oscillating between 0.66 g/day (R2) and 0.48 g/day (R1). It emerges from this study that juveniles of C. gariepinus make better use of rations made from fish meal.
