Abstract: This study was carried out with the aim of determining the effects of dietary super supplements on some physiological and growth indices in juvenile Siberian sturgeon (Acipenser baerii). A total of 180 fish after two weeks of adaptation, were randomly distributed in 15 fiberglass tanks (2000 liters). 12 fish were introduced to each tank. Super supplements at 2.5%, 5% and 10% were added to the diet and experiments were performed in triplicate. Samples were collected for the measurement of growth, blood, immune and osmotic indices during the rearing period. The results showed that the average final weight, final biomass, body weight increasing (BWI), specific growth rate (SGR), condition factor (CF) and daily growth rate (ADG) showed significant difference between control group with treated ones (P<0.05). According to the results, the use of super supplement improved growth and immune indices, particularly in the treatment containing 5% super supplement and adding it is recommended to the diet of A. baerii.
