In this pilot project fish with an average weight of 001/0 ± 40 g in the 250-liter tank for a week at a density of 5 fish were fed with regular food for the change to a workshop, A short time later the dominant fish as a completely randomized control group without adding multi-enzyme 1 and 3 treatment groups each with three replications in each tub distribution and Manually and three times a day at a rate of 3% biomass in 3 different levels 1500-1000-500 (g / kg Multi enzyme combo) fish added to the basal diet was fed for 60 days. Biometrics at the beginning, middle and end of the study period, growth was valid on the basis of formulas and references. The results showed that increased growth factors such as multi-enzyme causes a significant increase in final weight, feed conversion ratio, condition factor, percent of body weight, average daily gain and daily growth rate has been in the Siberian sturgeon and Maximum improvement in the use of growth factors Trkyb1000-1500 (g / kg multi-enzymes) were observed in the diet. The results showed that the use of multi-enzyme combination combo in the diet, significant positive effects on improving growth factors to Siberian sturgeon.
