Rehabilitating the floodplain of the lower River Dyje for fish.
Original language description
The lower reaches of the River Dyje were heavily modified. The river was straightened, isolating its meanders and reducing its length by 22%. The river bed showed a markedly lower diversity in both hydrological and morphological characteristics. Along the River Dyje an active floodplain (1300 hectares) has been preserved. These modifications have distinctly impacted the-living conditions of the indigenous ichthyofauna. Based on the results of our ichthyological investigations we have recommended a number of modifications that could improve the environmental conditions for fishes: (i) controlled flooding of the alluvial meadows, aimed at creating conditions for the spawning of phytophilous fish species; (ii) restoration of permanent connections betweenseparated river meanders and the River Dyje to increase the hydrological and morphological diversity in the river bed; (iii) creation of artificial pools in the floodplain to provide more suitable habitats for fishes.
