Abstract
In this study 1705 individuals have sampled during spawning season in five streams of Gorganroud basin and investigated the lengths and relative abundance. The length varied from 4.1-23.2 cm.there were significant difference in length frequencies between male and female in each streams and length classes. Sex ratio was 1:1.78. Male dominance was observed in all population. Sixteen length classes were present. Maximum frequency was length class length 8.9-10.1 cm for males and 7.7-8.9 cm for females. Males were more frequent in medium size. Females were in varied size.
