Abstract

In this study, different bony structures of totally 172 Alburnus chalcoides (Güldenstädt, 1772) individuals, caught from Almus Dam Lake between March 2006 and February 2007, were evaluated for age determination. Age and sex composition, age-length, age-weight and length-weight relationships and condition factor of population were examined according to ages of the most reliable bony structure. Scale, vertebra, lagenar (asteriscus) and utricular (lapillus) otoliths were remove for age analysis. Mean age, percent agreement, average percent error and coefficient of variation were used to compare the reliability of bony structures. Scale was found as the most reliable bony structure for age estimation. Ages of fish ranged between 1-3 year old. Sex composition was 57.56 % female, 28.49 % male and 13.95 % undetermined. For all fish, the mean total lengths and weights according to ages were calculated as 12.85, 14.70, 16.50 cm and 19.50, 29.24, 41.43 g, respectively. Length-weight relationship was designated as W = 0.0019 TL3.577 and condition factor was computed as 0.889

Özet

Bu çalışmada, Mart 2006-Şubat 2007 tarihleri arasında Almus Baraj Gölü (Tokat)’nden yakalanan 172 adet Alburnus chalcoides (Güldenstädt, 1772) bireyinin farklı kemiksi yapıları yaş tayini amacıyla değerlendirilmiş ve güvenilir bulunan yaş belirleme yapısına göre populasyonun yaş ve eşey kompozisyonu, yaş-boy, yaş-ağırlık, boy-ağırlık ilişkileri ve kondisyon faktörü incelenmiştir. Yaş tayini için pul, omur, lagenar (asteriskus) ve utrikular (lapillus) otolitler alınmıştır. Kemiksi yapıların karşılaştırılmasında ortalama yaş, yüzde uyum, ortalama yüzde hata ve değişim katsayısı kullanılmıştır. Yaş tayini için en güvenilir kemiksi yapı pul bulunmuştur. İncelenen örneklerin yaşları 1-3 arasında değişmiştir. Populasyonun % 57,56’sı dişi, % 28,49’u erkek ve % 13,95’i eşeyi belirlenemeyen bireylerden oluşmuştur. Populasyon genelinde yaş grupları için ortalama total boy ve ağırlıklar sırasıyla 12,85 cm, 14,70 cm, 16,50 cm ve 19,50 g, 29,24 g, 41,43 g olarak tespit edilmiştir. Tüm bireyler için boy-ağırlık ilişkisi W = 0,0019 TB3,577, kondisyon faktörü 0,889 olarak hesaplanmıştır
