This study was carried out between January 1996 and December 1997 in Kayaboğazı Dam Lake. During this period 424 specimens were examined. The age of females and males ranged from I to VII. The fork length and weight of females and males were 102-277 mm and 15-377.02 g and 125-274 mm and 27-369.02 g, respectively. There was no statistically significant difference between females and males in terms of body length and weight.The sex ratio (male:female) was 0.947:1. Gonadosomatic index values varied from 1.40 to 10.19. The sexual maturity age for males and females was III and IV, respectively. The spawning period was from the beginning of June to the end of July. The average number of eggs was estimated to be 42,724 ± 5658.93 for each individual. In addition, the regression equations were Log F = -2.18301 + 2.923 log L (r = 0.96) for fecundity and body length (L) and Log F = 2.889918 + 0.792 log W (r = 0.97) for body weight (W).
