Abstract
In the present study, the effect of different levels of dietary nucleotides (Vanazhen) as a food attractant on the growth rate and feeding rate of Persian sturgeon (Acipenser persicus) were studied. Fish with an average weight of 42/37 ± 2/12 g and mean length of 23/67 ± 0/61 cm were divided to 4 treatments with different levels of nucleotides in the diet (0, 0/25, 0/35 and 0/50%) with three replications containing 12 fish per tank. After 10 weeks feeding, survival, growth and feeding indices such as weight gain, specific growth rate, condition index, feed conversion and feed efficiency ratio were examined and the significance of them were analyzed using One-way ANOVA analysis software Spss 18. The best results in terms of weight and length compared to the weight gain, feed conversion ratio, specific growth rate and feed efficiency ratio from treatment 2 (0/35% of the nucleotides). This study showed that adding nucleotides to increase food intake, reduce food losses and thus increase the growth rate of sturgeon.
