Bu çalışmada, Harşit Çayı’ndan örneklenen 202 adet tatlı su kefali Squalius orientalis Heckel, 1847 bireyinin kondisyon faktörü değerleri, boy-ağırlık ve boy-boy ilişkileri tespit edilmiştir. Örneklemde dişi: erkek oranı 1,00:1,26 olarak hesaplanmıştır. Örneklerin total boy ve ağırlık değerleri sırasıyla 9,0-30,3 cm ve 6,54-325,26 g olarak tespit edilmiştir. Tüm örnekler için boy-ağırlık ilişkisi W=0,0056xTB3,227 (r2=0,995) olarak hesaplanmıştır. Boy-ağırlık ilişkisinin b değerine göre Squalius orientalis ’in tüm bireylerinde pozitif allometrik büyüme bulunmuştur (b>3, P<0,001). Ortalama kondisyon faktörü eşeyler arasında farklılık göstermemiştir (P>0,05). Populasyon genelinde ortalama kondisyon faktörü 1,004±0,0067 olarak tespit edilmiştir. Total, çatal ve standart boylar arasında kuvvetli ilişkiler tespit edilmiştir (P<0,001).

Condition Factor, Length-Weight and Length - Length Relationships of Squalius orientalis Heckel, 1847 Living in Harşit Stream

Öz

In this study, condition factor values, length-weight and length-length relationships of 202 chub, Squalius orientalis Heckel, 1847 individuals sampled from Harşit Stream were determined. Sex ratio (female:male) of population was calculated as 1.00:1.26. The total length and weight values of the samples were determined as 9.0-30.3 cm and 6.54-325.26 g, respectively. Length-weight relationship was calculated as W=0.0056xTB3,227 (r2=0.995) for all specimens. According to b value of length-weight relationship, the types of growth for all individulas was positive allometric in Squalius orientalis. There was no statistical difference in mean condition factor between females and males (P>0.05). The mean condition factor value was 1.004±0.0067 for entire population. All relationships among total length, fork length and standard length were highly significant (P<0.001).
