This research study was conducted in summer 2008 at Abzisytan Shrimp Aquaculture Hatchery Center in Bushehr, "Delvar" for 10 successive weeks (2 weeks for adaptation and 8 weeks for culture). The effects of dietary nucleotide at 5 levels of dietary including 0.0 %( control), 0.15%, 0.25%, 0.35% and 0.5% were investigated on the growth performance, and Whole-Body composition of Epinephelus coioides, with average weight of 10.70±0.29 and length 47.8 ±0.14, and with fifteen juveniles stocked in each tank which were fed by experimental diet. The results showed that SGR had a maximum rate in a 0.35% whilst WG, W2 and CF had a significant difference compared with control treatment. The best value of growth parameters were observed at dietary level of 0.35% nucleotide. Level 0.15% of dietary nucleotide resulted in better whole-body composition. There was a significant difference between %15, %25 and %35 compared with control. It is concluded that dietary with nucleotide positively influenced growth and chemical body composition of Epinephelus coioides.
