Cyprinus carpio is a non-native fish species in the India. Studies were undertaken during January 2015 to February 2016 from the Ken river (Vindhyan region), India. 505 fish specimens (247 males and 258 females) were examined of Cyprinus carpio for determination of population structure. Age composition ranged from 0+ to 10+ years with powerfully invaded in the river. The 1+ and 2+ age group was most exploited (20.65% each) population in case of male while in case of female 2+ age group was most exploited with 21.70%. After 2+ age group exploitation was decreased with increasing of the age of fishes. Male population was dominated in 0+, 1+ and 3+ age groups compared to female fishes. In stock, female population was more exploited than male. The 9+ and 10+ age groups of fishes were shared very minute proportion.
