Abstract

The present study describes the length-weight relationship (LWR) and condition factor of Ponticola turani (Aksu goby) based on 214 individuals from Terme Stream, the northern Turkey. Fish were collected by electrofishing in four different months between June 2015 and August 2016. LWRs of females and males were not significantly different within the same sampling month and among sampling months. The b value of LWR was calculated as 2.86 for females and 2.85 for males. Negative allometric growth was detected in both sexes, without significant difference between their b values. Fulton's condition factor (K) ranged from 0.72 to 1.48 in females and from 0.84 to 1.31 in males; the relative condition factor (Kn) ranged from 0.65 to 1.26 for females and from 0.76 to 1.18 for males. There was a significant difference in mean K of sexes, whereas no considerable difference was detected between their mean Kn. This research reports some biological parameters of Aksu goby for the first time.

Özet

Bu çalışma, Türkiye'nin kuzeyindeki Terme Çayı’dan 214 bireye dayanarak Ponticola turani (Aksu kayabalığı)’nin boy-ağırlık ilişkisini ve kondisyon faktörünü açıklamaktadır. Balıklar, Haziran 2015 ile Ağustos 2016 arasında dört farklı ayda elektroşok yöntemiyle toplanmıştır. Dişi ve erkeklerin boy-ağırlık ilişkileri aynı örnekleme ayında ve farklı örnekleme ayları arasında önemli farklılık göstermemiştir. Boy-ağırlık ilişkisinin b değeri dişiler için 2,86 ve erkekler için 2,85 olarak hesaplanmıştır. Her iki eşeyde de negatif allometrik büyüme saptanmıştır ve b değerleri arasında anlamlı bir fark bulunmamıştır. Fulton'un kondisyon faktörü (K) dişilerde 0,72 ile 1,48 ve erkeklerde 0,84 ile 1,31 arasında dağılım gösterirken; nispi kondisyon faktörü (Kn) dişiler için 0,65 ile 1,26 ve erkekler için 0,76 ile 1,18 arasında değişmiştir. Eşeylerin ortalama K değerleri arasında anlamlı bir fark tespit edilirken, Kn değerleri arasında önemli bir fark saptanmamıştır. Bu araştırma Aksu kayabalığının bazı biyolojik parametrelerini ilk kez rapor etmektedir.
