Revitalisation and fishes in the inundation area and the floodplain forests along the lower reaches of the River Dyje
Lusk, Stanislav ; Halačka, Karel ; Lusková, Věra ; Horák, Václav
The hydroeconomical modifications during 1968-1986 have changed fundamentally the natural hydrological regime of the lower Dyje River and adjacted floodplain. The proper stream channel was straightened and erected flood-oreventing leeves stopped natural floodings over the original floodplain substantial part. Elaborated and successively realised were specific rehabilitation projects that should eliminate negative impact of the modifications performed on the fish biota there. Concerned in the rehabilitation of the longitudinal and lateral migration permeability of the respective hydrological system for fish. That means to achieve the increase of aquatic habitat diversity by revitalisation of vanishing or by creation of new beckwater, pools and lagoons. The controlled inundation over a part of alluvial meadows has improved conditions for reproduction of phytophilous fish species. The rehabilitation of permanent connection in oxbows cut off (original river meanders) with the Dyje River will increase significantly the diversity of hydrological and geomorphological characteristics of the river bed channelised. The final goal is to create conditions for the ichthyofauna stabilisation and development in the respective area.
