Abstract

The present study has been carried out for the purpose of effects of different levels of dietary lipid levels on liver enzymes and blood hematological and biochemical parameters in juvenile Siberian sturgeon (Acipenser bearii) for 12 weeks. For this reason 120 juvenile Siberian sturgeon (15.6 ± 0.33g; mean ± SD) were distributed to 12 tanks, each containing 10 fishes. Four experimental diets with the same protein (45 %) and 4 fat levels 10, 15, 20 and 25 percent (as low, optimum, high and high level) was formulated. They were fed three times daily. During the breeding period, fish fed diets containing 15% fat had better blood (RBC, WBC and Hb), biochemical (glucose and lysozyme) and liver enzymes parameters (GOT and GPT) significantly in comparison with fish fed with 20 & 25% lipid. Based on the results of this study we can say that increased levels of fat in the diets of juvenile Siberian sturgeon up to 15 percent, improved biochemical and blood hematological parameters.
