Our study was concentrated on the effect of garlic peel on haematological parameters, biochemistry and digestive enzymes on beluga juvenile (Huso huso) with mean body weight of 18. 41 ± 0. 89 g after the feeding trial for 90 days. Garlic peel powder added with 0%, %0.5, %1, %1.5 and %2 of feed to basic sturgeon diet (49% protein and 14% lipid). ultimately, haematological parameters, biochemistry, digestive enzyme activity were evaluated. Results showed that the hemoglobin (Hb) was remarkably greater in the treatment fed garlic peel diet in comparison with the control (p<0.05), while others blood indices did not significant differences (p>0.05) between juveniles fed control and garlic peel supplementation diets. The group fed 1.5% garlic peel showed highly significant different in total protein (p<0.05).
