Abstract
This study evaluated the dietary effect of onion peel powder (OPP) on growth, blood chemistry, hepatic antioxidant enzymes activities and SOD mRNA responses of Clarias gariepinus. One hundred and twenty fish were randomly distributed into twelve plastic tanks and fed experimental diets for 42 days. Four diets (control, OPP-2, OPP-4 and OPP-6) were formulated with graded levels of OPP (0, 20, 40 and 60 g/kg diet) respectively. At the end of the experiment, the fish fed OPP supplemented diet exhibited significantly increased weight gain, specific growth rate (SGR) and better feed conversion ratio (FCR) compared to the control group (p
