The purpose of this study was to evaluate different levels of substitution of poultry slaughter waste powder for fish meal in fingerlings shirbut diets. Four isonitrogenous and isocaloric diets (30.22±0.02% CP and 19.75±0.015 MJ kg-1 diet) were formulated. Treatments included control (no poultry slaughter waste powder) and diets 1, 2 and 3 with 50, 75 and 100% replacement of poultry slaughter waste powder, respectively, with fish meal. Each treatment consisted of three replicates with 50 shirbut (1.5±0.05 g) in 400 liter fiberglass tanks and 3% biomass fed 2 times (8 am and 16) ad libitum. The results showed that there was no significant difference in growth performance between different diets (p>0.05). There was no significant difference between treatments in apparent digestibility coefficient , blood biochemical composition and carcass composition (p>0.05). Therefore, it can be concluded that replacement of fish meal with poultry slaughter waste powder in the diets of fingerlings shirbut can be done without any negative effect.
