Comparative Age Determination Methods of Silurus glanis L., 1758 Living in Altınkaya Dame Lake According to Their Bony Structures

Abstract

This study aims at the determination of most suitable bony structure among the otoliths, vertebrae, opercula and pectoral fin rays for the determination of ages of Silurus glanis L., 1758 living in Altınkaya dam lake. The study was carried out on 98 specimens caught between February 1992 and January 1993. The ages were ranged between 0 to XVIII according to vertebrae and II to II-XV according to pectoral fin rays. The comparison of these two data showed that they gave the same age for % 41.30 of the specimens. The age determination by the use of opercula and otoliths did not give satisfactory results. The genders of the samples were determined from the gonads and it was found that both the male and females dominated V years age group among the total population consisting of all age groups. It was found that vertebrae gave much better results compared to other bony structures
