  In this research, gonadosomatic index (GSI), growth pattern, condition factor (CF), and length-weight regression relationship (LWR) in farmed and wild Common carp (Cyprinus carpio) were investigated. In order to establish baseline for research, 85 wild and farmed common carp were prepared during the different season of the year (averagely 10 farmed and 10 wild fish per each season). The results showed that the CF in farmed Common carp was higher than wild carp. GSI didnand#39;t show any significant differences between wild and farmed Common carp (Pandgt; 0.05). The seasonal variation of GSI had significant differences between 2 groups (Pandlt; 0.05). Correlation index or LWR in wild carp (W=3.391 L 0.78) was higher than farmed carp (W= 2.679 L0.7) (Pandlt; 0.05). The line slope of farmed and wild carp were ln W= 2.68 ln L -3.738 and ln W= 3.391 ln L -5.65, respectively. In this study, growth estimates of wild and farmed common carp showed an Isometric pattern. The increasing trend of wild and farmed carpand#39;s GSI during summer to spring was according to spawning period of this fish. Manuscript profile
