Effects of different levels of dietary nucleotides (NT) were studied on muscle amino acid profile of rain bow trout with an average weight 11.35±0.32 over 8 weeks. This experimental was carried out in 700 L circular tanks with 40 fish per tank. NT was added to the diet at the rates of 0.0, 0.05, 0.1, 0.15 and 0.2%. Fish were fed 5 times a day at a rate of 3-5% body weight. After 8 weeks of feeding, the fish fed 0.2% NT showed higher SGR and WG (%) compared to the control group. No significant differences were observed in fish fed 0.2% NT compared to the fish fed 0.15% NT. The results showed that dietary supplementation of NT has significant effect on His, Arg, Thr, Val, Ilu, Leu, Phe, Lys, Glu, Ser, Gly, Tyr+Phe, TEAA and TNEAA. In fish fed 0.2% NT, total essential amino acid (EAA) content was significantly higher among the experimental groups.
