| Abstract | ||||
| The principal component analysis (PCA) of certain raw morphometric and meristic characters of Alestes nurse from the main course of th Nile at Aswan (latitude 240) and Assiut (latitude 27°), Egypt led to the presence of certain size morphometric forms and meristic forms. Moreover, by such an analysis, it is concluded that the relative variable position of the dorsal fin led to the recognition of three morphometric shap < /strong>e forms. By the app < /strong>lication of PCA and canonical variates analysis on certain shap < /strong>e characters in addition to the above ones, racial and sexual variations of Alestes nurse were revealed. Moreover, the racial variations in the meristic characters of that sp < /strong>ecies from different African areas were compared. | ||||
