A Comparative Study on Age Determination of Carp (Cyprinus carpio Linnaeus, 1758) in Lake Eğirdir Using Otolith, Vertebrae and Scale Counts

Abstract

This study, a comparative age determination study was carried out between May and November of 2013 in order to estimate most reliable bony tissue for ageing of the common carp in Lake Eğirdir. A total of 78 specimens aged between 1 and 11 were used in the study, having weights between 191 and 8685 g and fork lengths between 19.5 and 76 cm. Scales, vertebrae and otoliths were used by one reader via 5 replicates for ageing. Highest agreement among the bony tissues was found in otoliths (10.67%) and most reliable bony tissue was determined as otoliths for age determination in Lake Eğirdir carps.
