Abstract :
In this study from august 2008 to august 2009 through 12 sampling 298 Squalius cephalus were caught from mazandaran talar river. 123 of them were male, 115 of them female and sex of 60 specimen could not detect. In this research 26 morphometric attribute and 8 meristic attribute were examined. According to the obtained results average coefficient of variation in the morphometric and meristic speciality in male Squalius cephalus respectively were 28/24 and 96/6 and in female 97/35 and 66/7 also in 26 morphometric attribute and 8 meristic attribute in the male and female Squalius cephalus none significant (P>05/0). Also according to the obtained results by aid of analysis method to main factors (PCA) two groups have relatively good overlap. There is a strong correlation among the length and weight of male(r2=981/0) and female (r2=983/0) gender of Squalius cephalus in mazandaran talar river.
