This study conducted to study some biological traits of Carassius gibelio in Golestan dam and Voshmgir dam  from February to September 2015. During the study, 247 specimens from Golestan dam and 208 specimens from Voshmgir dam were sampled using small beach seine. The sex ratio of fish caught from Golestan dam to 1:10/23 and  the sex ratio of fish caught from the dam Voshmgir1: 10/56. The highest average gonadosomatic index (GSI) in Golestan dam for female to male June and May, respectively, were observed for females and males respectively 12/20 and 3/28 in the dam area Voshmgir for both female and male was observed on June 11/15 and 2/93 respectively for females and males respectively. The maximum total length and weight of Golestan dam area for females and males respectively 196/00 mm, 141/35 gr and 156/00 mm, 52/42 gr and in the dam area Voshmgir for females respectively 240/00 mm, 280/60 gr and for males was 00/179 mm, 81/75 gr. Minimum, maximum and mean absolute fecundity in Golestan dam with 327/71 respectively, 83134/09 and 13272/67 and in the dam area Voshmgir 4857/82, 430416/00 and 65270/02 and minimum, maximum and average were Relative fecundity (eggs per kg body weight) respectively in Golestan dam with 147/93, 5432/02 and 1002/48 and in the dam area Voshmgir respectively, with 100/94,  10722/34 and 1283/99 respectively. The mean diameter of 0/64 mm eggs in Golestan dam and from 0/11 to 1/39 and 0/62 mm and 0/13 to 1/11 Voshmgir dam area was variable.
