Urmia bleak ( Alburnus atropatenae ) is endemic to Iran and it has been reported from rivers of the Lake Urmia basin. In this research 274 specimens of this fish from seven rivers of Lake Urmia area including Aghdarreh, Nazloochai, Barandooz, Sarough, Zarrinehrud, Senteh and Talkhehrud were studied. In order to study the biometry, 17 traditional morphometric and 17 meristic traits and the method of morphometric geometric were used. Also, some biological traits, including length-weight, length-age and weight-age relationships, growth parameters of Vonbertalanffy, Condition Factor and Growth performance index were studied and compared. For statistical analyses, the nonparametric test, the analysis of variance and the discriminate function analysis were applied. The results from the analysis of Kruskal Wallis showed significant differences among the 17 morphometric traits, (p 0.05), indicating high variations among the studied populations. In the analyzes of PCA for morphometrics, six principal components with an eigenvalue of more than 1 was selected and these trait accounted for 77.44% of the variations. Plotting factors 1 and 2 of the PCA for traditional morphometric traits showed that Talkhehrud River population, to some extent, has been separated from other populations. In the analysis of meristic traits, six principal components with eigenvalue of more than 1 were selected and they accounted for 59.49% of the variations. Also plotting factors 1 and 2 for the meristic traits showed that Aghdarreh River and Nazloochai River populations were overlapped, but were separated from other populations. Also, Talkhehrud population was, to some extent, separated from Zarrinehrud population, and was completely separated from Saroogh population. In morphometric geometric, landmarks number 2, 3, 7, 8 and 9 had the highest variation. Also in canonical variate analysis, the population of Talkhehrud River were to some extent separated from other populations, and the population of Nazloochai River was completely separated from the population of Senteh and Zarrinehrud rivers. In comparison of the morphs there was no significant differences between the populations of Barandooz and Talkherud, Barandooz and Nazloochai, and Zarrinehrud and Senteh rivers (p 0.0001). Amongst these populations, Zarrinehrud and Senteh rivers showed the highest overlap. Also, the result showed some significant differences among the other populations (p 0.0001). Populations of Aghdarreh and Talkhehrud and Talkherud and Zarrinehrud were completely separated from each other and the most differences and landmark changed were observed between Aghdarreh and Talkhehrud populations. The morphemetric and geometric morphemetric methods could only separate the population of Talkhehrud from other populations to a great extent, in spite of significant differences among the seven populations.
