This study was conducted to compare the morphometric and meristic characters and biological parameters including length-weight relationship parameters and condition factor comparison of Urmia bleak (Alburnus atropatenae) from Mahabad-Chaie, Ghale-Chaie and Gedar-Chaie rivers of Lake Urmia basin. A total of 20 morphometric and 7 meristic traits were measured. Morphometric data was standardized to eliminate the effects of allometric growth. One-way ANOVA analysis were used for comparison of traits. The results of morphometric data showed a significant differences in all traits except fork length, ventral- pectoral and ventral- anal distance, pre and post dorsal length, head length and eye diameter. PCA, CVA and Cluster analysis were performed with these traits. CVA showed that Gedar-Chaie population distinguished from other populations, confirming by Cluster analysis. Also, studied population in terms of meristic traits showed a significance differences in branched rays of dorsal and anal fins lower gill rakers. Also, length-weight (LWRs) parameters and condition factor were estimated. Based on the results, the b values was 3.26 and 2.75 also condition factor were calculated 1.02 and 1.18 for the Mahabad-Chaie and Ghale-Chaie populations, respectively. Higher condition factor reflects the relatively favorable condition of their habitat in the studied rivers.
