Some Biological Features of Tench (Tinca tinca, L., 1758) Inhabiting Sıddıklı Dam

Abstract

The length–weight relationship, length–length relationship and the condition factor values of Tench, Tinca tinca (L., 1758) inhabiting the Sıddıklı Dam was described in this study. A total of 102 specimens captured between September 2015 and August 2016 were used to conduct this study. For each individual, the total length (TL), fork length (FL) and standard length (SL) as well as body weight were measured. Sex composition was determined as 49.02 % female, 43.14 % male and %7.84 undetermined sexes. The overall sex ratio showed no significant difference from the expected value of 1:1. Total length and weight of all specimens ranged from 5.9 to 38.6 cm and from 2.4 to 783.24 g, respectively. The length-weight relationships of females and males were W = 0.0068*TL3.232 (R2 = 0.991) and W = 0.0084*TL3.157 (R2 = 0.997), respectively. Weight increased positive allometrically with the total length for both sexes (b> 3, P< 0.001). The mean condition factor values of female and male were 1.305 and 1.330, respectively. This study brought the first data about the species in the Sıddıklı Dam to the literature.
