In this study, some population characteristics such as age, length, weight, condition, growth, mortality rates and size of carp (Cyprinus carpio L., 1758) population in the Lake Karamık were investigated. The ages, fork lengths and weights of the examined 108 individuals ranged between I-X years, 9-70 cm, and 16-8780 g, respectively. The mean condition factor of the population was calculated as 2.022. The length-weight relationship and von Bertalanffy growth equations were $W = 0.0245*L^{2.952} (r^2 = 0.996)$ and $L_t = 130^*[1-e{-0.0754^*(t+0.2452)}]$, respectively. The total (Z), natural (M) and fishing mortality (F) rates were Z = 0.40 $yr{-1}$ , M = 0.16 $yr{-1}$ , and F = 0.24 $yr{-1}$ , respectively. The number of fish longer than 25 cm in the population and their respective biomass were estimated as 47,847 individuals and 53,893 kg. In addition, it was determined that the maximum sustainable yield could be obtained with 60% of the present fishing effort.
