Abstract

Fluctuating asymmetry can cause developmental disorders in fish, and particularly high levels of asymmetry adversely affect fish life. In this study, the fluctuating asymmetry levels of the otoliths of four Alburnus species (A. chalcoides (Güldenstädt, 1772), A. tarichi (Güldenstädt, 1814), A. escherichii Steindachner, 1897, and A. mossulensis Heckel, 1843) found in Turkish inland waters were investigated. A total of 160 fish were collected in the Turkish inland waters. The fluctuating asymmetry level was calculated for the width and length characters of the asteriscus. Alburnus species, which were examined in the present study, were divided into four total length classes and fluctuating asymmetry of otolith was evaluated according to both the total length classes and species. There was significant difference between the right and left asteriscus otolith measurements for A. escherichii (P0.05). The highest and lowest asymmetry levels in the otolith length and otolith width were calculated in the A. escherichii among the Alburnus species. However, the highest and lowest asymmetry levels in otolith length and otolith width were calculated in the A. mossulensis among the total length groups of the Alburnus species. In this study, it was determined that the fluctuating asymmetry level varies according to different fish species and habitats.

Özet

Dalgalı asimetri, balıklarda gelişimsel bozukluklara neden olabilir ve özellikle yüksek düzeyde asimetri balık yaşamını olumsuz etkiler. Bu çalışmada Türkiye iç sularında bulunan dört Alburnus türünün (A. chalcoides (Güldenstädt, 1772), A. tarichi (Güldenstädt, 1814), A. escherichii Steindachner, 1897 ve A. mossulensis Heckel, 1843) otolitlerinin dalgalı asimetri düzeyleri araştırılmıştır. Türkiye iç sularından toplam 160 adet balık örneklenmiştir. Asteriskus otolitlerinin genişlik ve boy karakterleri için dalgalı asimetri düzeyi hesaplanmıştır. Bu çalışmada incelenen Alburnus türleri dört boy sınıfına ayrılmış ve otolitin dalgalı asimetrisi hem total boy sınıflarına hem de türlere göre değerlendirilmiştir. Sağ ve sol asteriskus otolit ölçümleri arasında A. escherichii için önemli farklılıklar bulunmuştur (P0.05). Alburnus türlerinden otolit boyu ve otolit genişliğindeki en yüksek ve en düşük asimetri düzeyleri A. escherichii türünde hesaplanmıştır. Ancak Alburnus türlerinin total boy grupları arasında otolit uzunluğu ve otolit genişliğindeki en yüksek ve en düşük asimetri düzeyleri A. mossulensis türünde hesaplanmıştır. Bu çalışmada dalgalı asimetri düzeyinin farklı balık türlerine ve habitatlara göre değişiklik gösterdiği tespit edilmiştir.
