This experiment was conducted in international researchery institute of Sturgeon fishes Shahid Dadman. The basal diet contained Fish meal as protein source (CP=40%). Five diets were supplemented with 5 graded levels of methionine, (0, 0.5,1 ,1.5, 2% Met per kg diet) . Each diet was randomly assigned to triplicate groups of 195 juvenile Huso huso (initial weight 31.9± 2.8) in fiftin 500-L circular fibere glass tanks. Fish were fed 4%of their body weight 3 times daily for 8 weeks. After 8 weeks, the analyzsis of growth indises and body composition by one-way analysis of variance (ANOVA) showed that: Weight gain, Body weight incerease(BWI) Specific growth rate)SGR(, feed coversion efficiency (FCE), Protein efficiency ratio (PER), Feed efficiency (FE), Hepatosomatic index (HSI) had no significant differences in different levels of methionine (P0.05).But body composition had significant differences in different levels of methionine( (P0.05)), especially in treat 4 (methionine 1.5%)(Pr
