Özet: Hybridization is a well-known phenomenon in closely related species sharing similar habitats. In the scope of this study, the first description of the hybrid population of Squalius semae and Alburnus sellal from upper Euphrates River is presented. Description was made based on museum material which collected in July 2006 by electrofishing equipment. The Principal Component Analysis was performed using 24 morphometric characters to compare the relationship between ancestor and hybrid individuals. The hybrid population characterized by a terminal mouth, a longer and slender caudal peduncle (its length 1.9-2.8 times its depth), 8½ branched dorsal-fin ray, 9½-10½ (mode 10½) branched anal-fin rays, 54-60 lateral line scales, 10-11 scale rows between dorsal-fin origin and lateral line, 5-6 scale rows between anal-fin origin and lateral line and 9-10+3-4 gill rakers on the outer side of first gill arch. Most of metric and mersitic data belonging to hybrid individuals placed between the data of Squalius semae and Alburnus sellal.
