A 70-day feeding trial was conducted with Clarias gariepinus juveniles to investigate the effects of partial substitution of soybean meal with sclerotium of Pleurotus tuber-regium on growth, economic parameters, nutrient utilisation, haematology and carcass proximate composition. Three experimental diets were formulated with graded levels of sclerotium (Diet 1: 10%, Diet 2: 15% and Diet 3: 20% inclusion) and the control without sclerotium. The results showed no significant difference (P > 0.05) in the growth, economic and nutrient utilisation parameters. The control group recorded the highest values for weight gain (102.37 g) and specific growth rate (3.15%/day) followed by Diet 1 (101.73 g and 3.13%/day, respectively). Though the best feed conversion ratio (1.43) was recorded in control group, Diet 1 recorded the highest values for protein intake (52.20 g) and net profit value (₦217.67/kg). With the exception of WBC, no significant difference (P > 0.05) was recorded in haematological parameters. Similarly, the carcass analysis did not show any significant difference (P > 0.05) across diets with the exception of the crude protein which was significantly low in the control diet.
