In this study, otolith biometry of mirror carp (C. carpio L., 1758) obtained from Keban Dam Lake were examined. For this purpose, 120 individuals (54 females and 66 males) were studied during November 2016-December 2016. After total length and weight of fish samples were determined, their sexes were also determined by examining of gonads. Then right and left otoliths were removed and cleaned. Otoliths weight were determined to the nearest ± 0.0001 g. The lengths and widths of otoliths were measured to the nearest ± 0.001 mm with a computer-aided image analysis program. The mean otolith weight (mg) values (right otolith-left otolith) of all population, the females and the males were (3.38-3.37), (3.29-3.29) and (3.45-3.44) respectively. The mean otolith length (mm) values were found to be (2.57-2.57), (2.56-2.54) and (2.58-2.59) respectively and the mean otolith width (mm) values were determined as (1.61-1.62), (1.60-1.60) and (1.62-1.63) respectively. The differences between right and left otolith data and between female-male otolith data were not statistically significant (P> 0.05). Otolith biometry-fish length relationships were also studied
