An 8- week feeding experiment was conducted to evaluate the effect of dietary betain as a feed attractant on growth, survival, body composition and resistance rate on kutum (Rutilus frisii kutum) fingerling. 225 fish by the initial weight of 2.26±0.2 g and density of 15 fish per tank. Five treatments of different levels of betain including 0 (control),0.5%, 1%, 1.5% and 2% added to diet containing 40% protein and 8% lipid. According to the results of this study, no significant differences in growth performance and feeding parameters observed between fish fed control and betain supplementation diets (p>0.05) . No significant differences in survival rate among all treatment groups (p>0.05). There were no significant differences in body composition among all treatment groups (p>0.05). Resistance rate were not influenced by the levels of betain (P>0.05). Totally considering betain did not show significant effect on the growth, surviving and resistance to stress in kutum fingerling.Journal
