Abstract: The ever-growing demand for the seed of Clarias gariepinus calls for the supply of fertile milt of high quality that would give high survival and growth rate. Studies have shown that Mucuna pruriens can influence fertility in men and animals. In this study, the effect of dietary velvet bean (M. pruriens) seed meal on reproductive performance was investigated in catfish C. gariepinus. Broodstocks of average weight of 275±25 g were fed diets supplemented with four concentrations (900, 1200, 1800 and 3400 mg kg-1) M. pruriens seed powder for eight weeks. Fish fed supplemented diets showed significantly improved reproductive performance over the control (0 mg kg-1 M. pruriens seed meal) treatment. The highest motility duration was obtained in fish fed with 3400 mg kg-1 of dietary M. pruriens seed meal and lowest in fish fed with 0.00 mg kg-1 of dietary M. pruriens seed meal. There was no significant difference in the sperm density of the experimental fish fed with different inclusion levels of dietary M. pruriens seed meal. The milt volume increased in fish fed with the different inclusion levels of M. pruriens seed meal. The findings suggest that feeding M. pruriens seed powder improved the milt quality of C. gariepinus.
