| This study was conducted to investigate the morphological variations of Patimar gobi, Ponticola patimari in Chalous, Kheirud and Tonekabon rivers, the middle part of the southern Caspian Sea basin. For this purpose, a total of 22 specimens were collected using electrofishing. In the Lab, some 22 morphometric characters were measured using digital caliper. Then, data were analyzed using One-Way ANOVA, Duncan test, principal component analysis (PCA), canonical variate analysis (CVA), and cluster analysis. The results showed that the studied populations have significant differences in 11 morphometric traits (P<0. 05). PCA and CVA analysis separated the studied populations; also, cluster analysis placed Kheirud in one clade and others in another one. The morphological characteristics in the head region as well as the pectoral fin lenght and the position of the anal fin were effective traits in population separation. |
