This study aims to determine the otolith characteristics of European perch living in Yedikir Dam Lake and to reveal therelations between total length and otolith dimensions. 195 fish samples were captured from Yedikir Dam Lake were measured for total, fork andstandard lengths and weighted. Sagittal otoliths were removed by making the left and right distinctions. Otoliths were photographed on the distalside and weighted (OW). Otolith length (OL) and breadth (OB) were measured with Leica Application Suit Ver. 3.8 image analysis program.Power (y=axb) and linear (y=a+bx) models were applied to estimate the relationships between the otolith measurements (OB, OL, OW) and totallength (TL). There was no difference in OB, OL and, OW between the right and left otoliths of P. fluviatilis (P˃0.05), but it was found that theotoliths of the female and male were significantly different (P<0.05). The relationships between otolith measurements and TL were determinedto be quite significant (P<0.001). r2 values of the relationships were changed between 0.957-0.969. The relationship between TL-OL in females,males and all individuals were found to be stronger than the others. This data is important in fishery biology studies. In recent years, studies onotolith morphology are quite common. The formation and growth of otolith are related to the growth of the fish. It is thought that this study willprovide data to be carried out concerning perch and especially to be used in stock separation studies.
