A total of 218(Abdal (N=44), Akçay (N=57), Terme (N= 55), Yedikır (N=62)) chub individualswere sampled from different localities. All captured individuals were measuredto the nearest 0.1 cm for total, fork and standard lengths. The weight of eachsample (W) was recorded (0.01 g). According to results of analyses, there wereno statistically significant differences between sexes in terms of length and weight(P˃0.05). So, entirepopulations (female+male) were evaluated together for analyses. The averagetotal lengths of chub sampled from the Abdal Stream, Akçay Stream, Terme Streamand Yedikır Dam Lake varies between 11.49±0.792, 10.31±0.518, 10.33±0.289 and11.11±0.327 cm, respectively. The length-weight relationships (LWRs) were foundhighly significant (P < 0.001, r2 > 0.990) for all localities.The value of ‘b’ of LWR was significantly different from 3.0 in chub and thegrowth type is possitive allometric for all localities. The equations oflength-weight relationship were calculated as W=0.007TL3.224,W=0.006TL3.285, W=0.005TL3.298, W=0.007TL3.210for Abdal, Akçay, Terme and Yedikır, respectively. Length-length relationshipwas also highly significant (P<0.001) with coefficient of determination (r2)ranging from 0.916 to 0.999.

Toplamda 218 (Abdal (N=44), Akçay (N=57), Terme (N=55), Yedikır (N=62)) örnek farklı lokalitelerden örneklenmiştir. Yakalanan tümörneklerin total, çatal ve standart boyları (0.1 cm) ölçülmüştür. Her birörneğin ağırlığı (W) kaydedilmiştir (0.01 g). Analiz sonuçlarına görecinsiyetler arasında boy ve ağırlık bakımından istatistiksel olarak önemli birfarklılık yoktur (P˃0.05). Bu sebeple tüm populasyon (dişi+erkek)analizlerde birlikte değerlendirilmiştir. Abdal Çayı, Akçay Çayı, Terme Çayı veYedikır Baraj Gölü’nden örneklenen tatlısu kefalinin ortalama total boylarısırasıyla 11.49±0.792, 10.31±0.518, 10.33±0.289 ve 11.11±0.327 cm arasındadeğişmektedir. Boy-ağırlık ilişkileri tüm lokaliteler için önemli bulunmuştur(P < 0.001, r2 > 0.990). Boy-ağırlık ilişkisinin “b” değeriistatistiksel anlamda 3’ten faklıdır ve tüm lokaliteler için büyüme tipipozitif allometriktir. Boy-ağırlık ilişkilerinin denklemleri sırası ile Abdal,Akçay, Terme ve Yedikır için W=0.007TL3.224, W=0.006TL3.285,W=0.005TL3.298, W=0.007TL3.210olarakhesaplanmıştır. Boy-boy ilişkilerinin regresyon katsayıları 0.916 ile 0.999arasında değişim göstermektedir ve istatistiksel anlamda önemlidir(P<0.001). CR - Altındag, A. (1996).
