In this study, some morphometric characters of Rudd, Scardinius erythrophthalmus and Elmali Rudd, Scardinius elmaliensis were determined and compared. One S. erythrophthalmus samples collected from different locations and 27 S. elmaliensis samples collected from Avlan Lake (Elmali-Antalya) were examined and morphometric characters, were measured at each specimen. In addition, meristic characters including the number of fin rays, the number of lateral line scales and the number of gill rakers were counted. The ratios between the morphometric characters were also calculated. The total length of S. erythrophthalmus individuals varied between 5.5 and 22.5 cm while the total length of S. elmaliensis individuals varied between 6.8 and 20.1 cm. The maximum body height standard height, eye diameter-nose length, eye diameter-head length and nose length-head length ratios revealed that the two species were statistically different from each other.
