Among the whitefishes (cyprinid's) there are a quite a lot species who at least make migrations from time to time. Some of these species are to be presented here. The whitefishes of our rivers are so-called potamodromous (within the rivers) migrating species. Migrations are being made in different lifestages. While growing up young indviduals leave the flat waterzones into deeper waterareas. Often there is a change between summer and winterhabitat. Regularly there are spawningmigrations to appropriate spawningplaces.
