Abstract. This study has been performed to evaluate the alternative effects of the poultry by-product meal (PBM) instead of the fish meal (FM) in the replacing 0 (control group), 25, 50, 75 and 100% of FM by PBM diets on the chemical compositions of the body in Huso huso. Five iso-nitrogenous and isocalorical diet % of PBM were fed to three replicate groups of H. huso with initial weight of 1200±200 g during 90 days. The results showed crude protein of body were not different among fish fed with control diet and 25% replacement. But, body protein decreased as the level of the replacement increased and fish fed with 100% replacement had showed a significant difference with the control treatment (p > 0.05). The crude lipid level showed highest value in fish fed with 100% replacement (23.19%). But did not differ significantly among control and 25% replacement groups. The ash of body in the treatment with 100% replacement showed highest value but the treatment with 50% replacement had no significant difference with the control treatment (p > 0.05). Nitrogen-Free Extract (NFE) of body showed no significant difference with the control treatment at the level replacement of 50% but it was highest in 100% replacement group.
