Abstract
Movement ethology in fishes is the most important key in fish population dynamics. However, this science is remained limited. Based on leptokurtic dispersal kernels, movement ethology of fishes contained form three parameters which is (i) a stationary component and (ii) a mobile component as well as the (iii) share of each component (p). According to these three parameters and fish length, aspect ratio of the caudal fin, stream size and duration of the study; movement distances in fish can be calculated by R and through fishmove package. Therefore, in this study, movement ethology of Rutilus frisiiinvestigated based on leptokurtic dispersal kernel. In addition, this study tried to approximate how recruitment could be more successful if we had more knowledge about movement ethology of Caspian kutum in its habitat.
