The aim of this study was to determine the effect of Ultra-Amax perboitic on 1 g / kg diet Morphometric characteristics, growth performance and nutrition indices in adult male and female Huso huso for 120 days. For this purpose, 60 fishes with an average weight of 4.24± 0.27 kg after one week's adaptation They were randomly divided into 2 treatments and each with three replicates (with 10 replicates per each). The results showed that ultra-Amax prebiotics produced a significant difference in morphometric factors. But it did not affect the parameters such as Fork length and body length in the pectoral Fin. However, adding 1 g / kg of ultra-Amax perbiotic to fish diets Improved growth and nutrition parameters, specific growth rates, relative weight rates, daily growth rate, feed conversion ratio and relative eating were improved, However, no significant difference was observed between treatments   (P>0.05). The amount of obesity and nutritional conversion efficiency indicated a significant difference between treatments with control treatment. Based on the data analysis, it has been shown that commercial ultra-Amax is a more effective and effective effect on Adult male Huso huso. The total results of this study showed that dietary supplemented diets with ultra-Amax of 1 g / kg diet Can be effective in improving morphometric factors and growth performance and nutritional indices.
