The Kura population was identified as  R. macropterus. However, we observed some morphological differences between Kura and Aras populations obtained in this study. The Aras population has a slenderer body and caudal peduncle than  R. macropterusfrom Kura (Fig. 4d, 4e). Therefore, we encourage detailed morphologic and molecular research including the Kura, Aras and Urmia populations to clarify the taxonomic position of the Aras population. 2020-01-01 2020-12-31 2020-01-01 41.0709 Kura River 6 42.4844 1 2020-01-01 2020-12-31 2020-01-01 Kura 40.9669 Stream Cakir 6 42.5861 Cakildere 1 2020-01-01 2020-12-31 2020-01-01 Aras 40.5814 Not 6 43.0591 Stream Kars 1 2020-01-01 2020-12-31 2020-01-01 39.9699 Aras River 6 41.8883 1
