Evaluation of some hematological and serum biochemical indices of juvenile Siberian sturgeon (Acipenser baerii) fed different levels of glucose and corn starch

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 (P0.05). 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.
