Subyearling Siberian Sturgeon Acipenser baeri Fed a Diet Supplemented with ImmunoGen: Effects on Growth Performance,...

In this research, the effect of ImmunoGen (IMNO) on the growth indices, hematological parameters, and carcass composition of Siberian Sturgeon Acipenser baeri was investigated. After acclimation, fish (274.8 ± 16.2 g) were allocated into 12 tanks (10 fish per tank) and triplicate groups were fed a control diet (0%) or diets containing 0.5, 1.0, or 1.5% IMNO for 75 d. At the end of the experiment, final length, final weight, and weight gain were significantly higher in the fish fed the diet containing 1.0% IMNO, though no significant differences were observed between the control and experimental diets containing 0.5% and 1.5% IMNO. In addition, there were no significant differences among diets in terms of hematological parameters and carcass composition. However, dietary IMNO significantly affected the serum biochemical parameters of Siberian Sturgeon, such as cholesterol, triglycerides, and IgM, with the highest level of IgM occurring in the 1.0% IMNO treatment and the lowest levels of cholesterol and triglycerides in the 1.5% IMNO treatment. The findings of this study thus indicate that the administration of 1.0% IMNO in diet positively affects the growth factors and some serum biochemical parameters of Siberian Sturgeon.
