Reproduction Properties of Wels Catfish (Silurus glanis, L., 1758) Inhabiting Sıddıklı Reservoir

Öz

In this study, some reproduction properties (sex ratio, reproduction period, egg diameter and fecundity) of Silurus glanis inhabiting Sıddıklı Reservoir were investigated. A total of 200 samples were caught between September 2015 and August 2016 from different regions of Sıddıklı Reservoir. Sex ratio was calculated as 0.88:1.00 (Female: Male). The sex ratio was not statistically different from the expected 1.00:1.00 (χ2= 0.841, P>0.05). The values of gonadosomatic index (GSI) varied from 0.033 to 11.80 in females and 0.008 to 0.451 in males. According to GSI values, reproduction period of the S. glanis in Sıddıklı Reservoir was determined to be between April and June. The mean total fecundity and egg diameter were calculated as 46343 eggs/individual and 1.758 mm, respectively. Relative fecundity for each kilogram of female fish was 13000 eggs. The strong relationships between total fecundity-length and total fecundity-weight were determined (r2>0.80).
