EFFECT OF DIETARY PREBIOTIC INULIN ON HEMATOLOGICAL AND BIOCHEMICAL PARAMETERS OF CULTURED JUVENILE BELUGA (HUSO HUSO)

Use of prebiotics, nondigestib le dietary ingredients that beneficially affect the health host, is a novel concept in aquaculture. The aim of this study was to evaluate the effect of inulin supplementation on hematological and biochemical parameters of juvenile beluga (Huso huso). An 8-week trial was carried out to investigate the effects of different dietary prebiotic inulin at 0.0%, 1.0%, 2.0%, and 3.0% on hematologic and some blood serum nonelectrolytes of cultured juvenile great sturgeon (Huso huso). Blood samples were collected from caudal vein of 36 apparently healthy fish (average weight 65 g) at the end of trial. Data was analysed by regression analysis and pearson correlation test. No significant differences (p>0.05) were observed in serum enzymes between treatments. There were no differences in the RBC, MCH, glucose, albumin, cholesterol, triglyceride and uric acid between treatments. A significant elevation (p<0.01) of Haematocrit, WBC and lymphocyte was found in the fish fed diet 1.0% inulin. The results indicate that dietary administration of inulin at the level of 1.0% can positively influence on some blood parameters of cultured juvenile great sturgeon
