In this study, the effect of dietary phytase and wheat bran on some growth performances and phosphorus absorption function of common carp fry for 60 days was assessed. A total number of 180 common carp fry (20±1 initial weight) was randomly distributed in six experimental groups including, control group without any additive (basal diet), T1 (basal diet+2000 IU/Kg phytase), T2 (basal diet+4000 IU/Kg phytase), T3 (basal diet+20 g/Kg wheat bran), T4 (basal diet+40 g/Kg wheat bran) and T5 (basal diet+2000 IU/Kg phytase+20 g/Kg wheat bran). The highest body weight (150.02±4.76 g), specific growth rate (0.65±0.19%), and condition factor (3.20±0.26%) was observed in T5 (p<0.05).  However, the lowest FCR (2.53±0.70) was seen in T5 (p<0.05). Also, the highest phosphorus concentration in the fry bones (2.54±0.003 ppm) was recorded in T5 (p<0.05). Results showed that using of 2000 IU/Kg phytase and 20 g/Kg wheat bran in the diet can improve growth indices and phosphorus absorption rate of common carp fry.
