Utilization effects of substituting maize with graded levels of ripe and unripe banana (Musa sapientum) peels in the diet of African catfish (Clarias gariepinus) juveniles
Six diets were produced using graded levels of banana peels (5 %, 10 % and 15 % for both ripe and unripe banana peels) which were compared with the controlled diet containing maize in the diet of C. gariepinus juveniles. Feeds were fed to triplicate groups of ten fish each to satiation twice daily for ten weeks. There were significant differences (p < 0.05) in Mean Weight Gain (MWG) and Specific Growth Rate (SGR) amongst the experimental diets. The control diet had the highest MWG (58.40~c 5.27g) and SGR (1.877~c 0.09 %) while the least values of MWG (25.03 g) and SGR (0.35 %) were recorded in Diet 3(15 % unripe banana peels). The Feed conversion ratio, Protein efficiency ratio and Protein intake recorded significant differences (P < 0.05) between the control and the experimental diets. Similarly, significant differences (P < 0.05) were recorded in Profit Index, Incidence of Cost and Economic Investment Cost Analysis between the control and experimental diets. Histometry analysis of fish organs equality recorded significant differences (P < 0.05) between the control and other test diets. Although the Control diet had the best growth performance, it recorded the least profit index (1.87) while Diet 2 (10 % ripe banana) had the highest Profit Index (3.11). Hence, graded levels of plantain peel is a profitable alternative energy source for partial replacement of maize up to 10 % ripe and unripe banana peels in diet of C. gariepinus.
