Effects of super supplements on growth and some physiological indices in farmed juvenile Siberian sturgeon (Acipenser baerii)

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
