Karasu Nehri’nde (Doğu Anadolu, Türkiye) yaşayan Squalius cephalus (Linnaeus, 1758)’un yaş ve bazı büyüme parametreleri

Bu çalışma, Karasu Nehri’nin 14 farklı istasyonunda yaşayan tatlısu kefali, Squalius cephalus (Linnaeus, 1758) ‘nin yaş tayini ve bazı büyüme özelliklerinin araştırılması ile ilgilidir. Bu amaçla, 2014 ve 2016 yılları arasında elektroşokerle toplam 196 S.cephalus balık örneği (100 dişi ve 96 erkek) yakalandı. Dişi/erkek oranı 1/0,96 idi. Yakalanan balıkların minimum-maksimum uzunluk ve ağırlığı 7,6-23,9 cm ile 4,8-198,2 g olarak belirlendi. Yaş grupları 0-6 idi. von Bertalanffy büyüme parametreleri tüm bireyler için L∞=31,98 cm, g, k=0,136 yıl-1, t0 =-1,40 yıl olarak hesaplandı. Büyüme performans indeks değeri (Ф’) 2,143 olarak hesaplandı. Tüm bireyler için boy ve ağırlık ilişkisi W=0,0060L3,27 (R2 =0,98) dir. Yaş grupları ve cinsiyetler arasındaki kondisyon faktörlerinde farklılıklar istatistiksel olarak anlamlı bulundu (P > 0,05 t-test).

Age and some growth parameters of Squalius cephalus (Linnaeus, 1758) inhabiting Karasu River (East Anatolia, Turkey)

The present study was carried out concerns a research of the age determination and some growth parameters of chub, Squaliuscephalus (Linnaeus, 1758) living in 14 different station from Karasu River (East Anatolia, Turkey). For this purpose, a total of 196 fish specimen(100 females and 96 males) of S.cephalus were captured between 2014 and 2016 by electroshocker. Female/male ratio was 1/0.96. Minimummaximum length and weight of captured fishes were determined as 7.6-23.9 cm and 4.8-198.2 g, respectively. The age groups weredetermined between 0 and 6. The parameters of von Bertalanffy growth function estimated as L∞=31.98 cm, k=0.136 year-1,t0=-1.40 year for allindividuals. The growth performance index (Ф›) value was computed as 2.143. The length and weight relationships W=0.0060L3.27 (R2=0.98) forall individuals. Significant statistical differences in condition factors between age groups and sexes were not found (P > 0.05, t-test).
