Abstract

Algae Scarpers is one of the most abundant species of fresh water in Iran, and the species Capoeta saadii has the highest distribution in Iranian ecosystems. The high density of this fish in domestic waters has led to the study of biological characteristics and the effort to introduce it to the breeding system for human consumption. For the purpose of this study 44 specimens from Roudbal River and 30 specimens Qara Aghaj River were captured by the electroshoker and fixed in 10% formalin solution and their morphometric charactrise were measured using by digital caliper. Before analysis, morphometric data were standardized by Beachham (1985). The analysis of morphometric characters of Roudbal and Qara Aghaj showed that head length, caudal peduncle, eye diameter and premaxilla have the greatest role in the separation of populations. The results were analyzed by PCA statistical test, based on the morphometric characteristics of the separation between populations.
