This study was carried out to compare the effect of different culture systems on the growth performance and body composition of common carp (Cyprinus carpio). Fish juvenile was selected by initial average weight of 21.5 ±0. 3 after designs the systems and adaptation period were randomly distributed in fiberglass tanks (with 100 liters capacity). The experiment lasted for 2 months.  At the end of experiment, growth parameters including final weight, weight gain percentage, specific growth rate, survival; and whole body proximate analyses including protein, fat and ash levels were examined. Finally, there were significant differences in final weight, specific growth rate, and feed conversion ratio and survival rate between experimental treatments (p<0.05). There was no significant difference between treatments (biofloc, recirculating aquaculture system) for whole body’s moisture, fat and protein (p>0.05). But there was a significant difference among body protein, ash and fat among control 2 treatment and other treatments (p<0.05). Also there was no significant difference between biofloc and recirculating aquaculture system for lysozyme and complement activity in treatments whereas the fish in biofloc showed a significant higher superoxide dismutase than the others (p<0.05). The results obtained in this experiment, suggest that biofloc improves growth parameters, immune response even with decreasing percentage of daily feeding in common carp.
