Abstract

 In this study the morphometric and meristic characteristics of 98 specimens of Garra rufa collected from the Gamasiab, Aran, and Dinvar Rivers (Karkheh River drainage) and Bazoft and Armand rivers (Karun River drainage). The samples were transferred to the Lab after anesthesia and fixed into the buffered formalin 10%. Thirty-three morphometric and 9 meristic traits were measured and counted using digital caliber and stereomicroscope, respectively. Morphometric data were standardized based on the ratio of the head and standard lengths. To compare the studied populations, in terms of the morphological features, One-Way ANOVA, Duncan test, PCA (Principal Component Analysis), CVA (Canonical Variate Analysis) and CA (Cluster Analysis) were used. The results showed a significant difference among the studied populations in all morphometric data except post dorsal- pre Anal and Post-orbital lengths and in lateral and lower line scales, upper and lower gill rackers (p < 0.05). CVA and CA analysis showed population grouping as well. The morphometric was better than those counting traits in expressing the differences among the studied populations.
