This research was carried out to determine the effect of glucose and corn starch on hematological and serum biochemical indices of Siberian sturgeons. A total of 120 Siberian sturgeons weighing 25.64±2.80g were treated with diets containing glucose 15%, glucose 30%, corn starch 15% or corn starch 30% (four treatments in three replicates) for 8 weeks. Results showed that fish fed corn starch 15% had the highest amount of hematocrit, hemoglobin and number of red and white blood cells, that revealed the significant difference with corn starch 30% treatment (P<0.05). The highest number of lymphocytes belonged to the fish fed glucose 15% and 30% that showed significant difference with corn starch 15% treatment (P<0.05). No significant differences were observed in glucose, cholesterol, triglyceride, total protein, globulin and albumin between experimental treatments (P>0.05). Fish fed glucose 30% showed the highest contents of liver enzymes (P>0.05). No significant difference was found in a-Amylase enzyme among trial treatments. Nevertheless, glucose 30% treatment had the lowest level of a-Amylase enzyme. According to results, corn starch at the level of 15% could improve and reinforce some hematological and biochemical parameters in Siberian sturgeon.
