Özet:

In this study, otolith biometry-total length relationship was investigated in longspine scraper, Capoeta trutta (Heckel, 1843) obtained from Özlüce Dam Lake, which was built on Peri Stream at Elazığ-Bingöl province border. For this purpose, a total of 115 fish samples (60 male and 55 female) were examined between September 2017 and December 2017. The sex determination was made after the total length of them was measured. The left and right otoliths of each fish were removed and they were made ready for measurement. Otolith weights (OA) were determined to a precision of 0.0001g. Otolith length (OU) and otolith width (OG) were measured using a computer-assisted image analysis program. The differences between right and left autoliths and between male and female autoliths in terms of OA, OU and OG values were not statistically found significant. In the all population, TB, OU, OG and OA values were found as 118-381 mm, 1.536-3.734 mm, 1.049-2.585 mm and 1.10-13.90 mg respectively. The relationships of TB with OU, OG and OA were found to be positive and strong.
