Morphological differences among the Cyprinion macrostomus (Cyprinidae) populations in the Tigris River

Abstract

In this study, by examining the character of the morphometric and meristic in which Cyprinion macrostomus samples obtained from different locality in Tigris, morphometric character which are transformed subject to discriminant analysis and depending on grouping model to number of discriminant functions and according to importance of these totally variance, morphogical variance among populations are determined. According to the result of discriminant analysis of Cyprinion macrostomus individuals belonging to 5 different locality of Tigris River, it is determined that the individuals belonging to Tigris River are different from other localities both in terms of morphometric and meristic, the samples of Göksu Stream is different from other localities only in terms of meristic Devegeçidi, Kulp and Kayser Stream samples are similar in terms of morphometric and meristic.
