Abstract

Different bony structures as scales, vertebrae, otoliths, opercles and subopercles of 156 red mullet (Mullus barbatus ponticus Essipov, 1927) sampled from the Black Sea were removed for age determination. Otoliths were read once by two experienced readers. However, due to the difficulty of interpretation of annuli on the otolith edge, the broken-burnt method was applied to the 61 otoliths. Broken-burnt otoliths were also read once by the same two experienced readers. When whole otolith and broken-burnt otolith ages were compared, high agreement within structures and low precision between structures were observed. Finally, it was found that the age of fish was underestimated by a minimum of one year by whole otolith. Therefore, we recommend that the broken-burnt otolith method should be used in the age determination of red mullet.

Özet

Karadeniz’den örneklenen 156 barbunya bal›¤› (Mullus barbatus ponticus Essipov, 1927)’n›n pul, omur, otolit, operkül ve suboperkül gibi farkl› kemiksi yap›lar› yafl tayini için al›nm›flt›r. Otolitler yafl belirlemede tecrübeli iki okuyucu taraf›ndan bir kez okunmufltur. Ayr›ca otolit kenar bölgesindeki annuluslar›n yorumlanmas›nda zorluk çekilen 61 otolite k›rma-yakma metodu uygulanm›flt›r. K›r›l›p-yak›lan otolitler de ayn› iki okuyucu taraf›ndan bir kez okunmufltur. Bütün otolit ile k›r›k otolit yafllar› karfl›laflt›r›ld›¤›nda, yap›-içi uyumun yüksek, yap›lar-aras› uyumun ise düflük oldu¤u gözlenmifltir. Sonuç olarak, bütün otolitlerin bal›k yafl›n› en az 1 yafl düflük gösterdi¤i bulunmufltur. Bu nedenle, barbunya bal›¤›n›n yafl tayininde k›r›k otolit metodunun kullan›lmas› önerilmifltir.
