Keban Baraj Gölü'nde Yaşayan Capoeta trutta (Heckel, 1843)'da Otolit Biyometrisi-Balık Boyu İlişkisi.

In this study, the relationship between otolith biometry and total length of 48 females and 58 males belong to Capoeta trutta (Heckel, 1943) population of Keban Dam Lake (Elazığ) were examined between Nov ember 2011 and December 2012. After total length of fish sample were determined to the nearest ±1 mm, their sexes were determined by examining of gonads. Then right and left otoliths were removed and cleaned. Otolith weights 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 thickness of otoliths were measure to the nearest ± 0.01 mm with a digital compass. The difference between right and le ft otolith data were not statistically significant (p>0.05). Therefore, only right sagittal otoliths were used for the determination of otolith biometry. The ages of fishes were determined. Mean values of otolith lengths, otolith widths, otolith weights and otolith thickness for male, female and all population were 3.06, 3.08, 3.07 mm; 2.24, 2.31, 2.27 mm; 6.94, 7.53, 7.20 and 1.12, 1.4, 1.13 mm respectively. According to correlation analyses results, moderate positive relationship in male, female and all population were found between otolith length-total length (r=0.33, r=0.46 and r=0.38), otolith width-total length (r=0.45, r=0.54 and r=0.49), otolith weight -total length (r=0.51, r=0.72 and r=0.65), otolith thickness-total length (r=0.48, r=0.55 and r=0.50) respectively.
