In order to compare the geometric morphometrics of teilehkhus (Capoeta capoeta) populations, 713 specimens from 32 rivers in Caspian Sea, Urmia and Harirud basins were examined. Specimens were anesthetized in 1% clove oil solution after catching by a seine net and fixed in 10% formalin and transfered to laboratory for further studies. The specimens were photographed in a sililar condition by a Cannon 8MP and land marked in Tpsdig2 software. Superimposition of the landmarks was performed by Procrustes analysis to eliminate non-shape variations in TpsRelw. The Canonical Variate Ana;ysis (CVA) results of geometric morphometry showed significant differences among the populations and Harirud population was fully separated from Urmia populations. Caspia Sea population overlapped the both other populations. The Cluster Analysis (CA) grouped Harirud and Caspian Sea populations as a separate group from Urmia population, indication a more similarity between the Harirud and Caspian Sea populations. However, for more details, molecular studies are needed.
