The lower reaches of the Dyje River with adjacent floodplain constitute an unique territory fragment in the Czech Republic. Its hydrological system is prominent with a high diversity of aquatic habitats including natural floodings over the floodplain part. During last 50 years, the occurrence of 49 species fish was found there in total. Of them, 41 species are assessed to be autochtonous, i.e. 75% of the native ichthyofauna structure of the Czech Republic. As strategically significant, the direct barrier-free connection of the lower Dyje River through the Morava River with the Danube has been manifested. In such way during recent years, the occurrence has been renewed of naturally immigrating Pelecus cultratus, Gymnocephalus schraetser and Zingel zingel, which had disappeared in the past. Sporadically, also the occurrence of Acipenser ruthenus and the wild form Cyprinus carpio is renewed. Naturally in the territory of the Czech Republic, new species such as Carassius auratus, Proterorhinus marmoratus, Sander volgense and Gymnocephalus baloni have penetrated. This unique territory is intended to be proclaimed for the Biospherical reserve and as protected territory for selected fish species within the NATURA 2000 system.
