Abstract
The effects of feeding varying levels of boiled Pueraria phaseoloides seed meal in the diet of Clarias gariepinus juveniles for growth performance and feed utilization was investigated in comparison with conventional commercial fish feed. Partial replacement of fish meal with varying levels of P. phaseoloides seed meal at 10%, 20%, 25% and 30% were fed to Clarias gariepinus juveniles for 56 days. The experiment comprised of six treatments with 12 replicates in the Fisheries laboratory, Department of Biological Sciences, Ahmadu Bello University, Zaria, Nigeria. Data for each parameter were subjected to Analysis of Variance (ANOVA) and the means for various experimental diets were compared for significance differences at 5% level. Fish fed with (diet C) 20% had the best mean weight gain (MWG) of 61.11g, mean length gain (MLG) of 9.57cm, specific growth rate (SGR) of 1.93, feed conversion ratio (FCR) of 0.74, apparent net protein utilization (ANPU) of 2.54, Feed efficiency ratio (FER) of 1.35, and Gross Feed Conversion Efficiency (GFCE) of 11.19. While diet E (30%) boiled Kudzu gave the least growth performance. The fish carcass composition was significantly higher (P<0.05) with diet C 20% boiled Pueraria seed inculusion this is indicative that protein in the feed was deposited into flesh of the fish.
