Status and protection of species and intraspecific diversity of the ichthyofauna in the Czech Republic.
Original language description
The ichthyofauna indigenous to the Czech Republic consists of four lamprey and 55 fish species. Of these, two lamprey and eight fish species are considered now absent. In recent years some of the previously lost species have reappeared either through natural migration (Acipenser ruthenus, Pelecus cultratus, Gymnocephalus schraetser) or reintroduction (Salmo slar). As a result of natural immigration from the Danube drainage basin, the indigenous ichthyofauna has been enriched by species new to the CzechRepublic: i.e. Proterorhinus marmoratus, Stizostedion (Sander) volgensis, and Gymnocephalus baloni. According to the IUCN (1999) classification, 19 fish species, one wild form, Cyprinus carpio, and two lamprey species are endangered to different degrees.Recent investigations on intraspecific diversity has yielded data on the genetic variability in populations of Chondrostoma nasus (average variability, low interpopulation diversity), Vimba vimba (low genetic variability), Barbus barbus
