Abstract

In this study, a total of  95 Alburnoides tabarestanensis were caught in four rivers including Zaringol, Tilabad, Zav and Yelcheshme from July to November 2016. 36 morphometric and nine meristic characteristics were studied. Standardized data were analyzed using PCA to determine the differences between the studied populations. In obtained results using the PCA method from the morphometric characteristics of four rivers, there were observed the distinction of populations and some of the morphometric characteristics of A. tabarestanensis are separated. But the meristic characteristics of this fish in four mentioned rivers very close together, and there was high overlap in their characteristics.
