Název v původním jazyce

Rehabilitating the floodplain of the lower River Dyje for fish.

Popis výsledku v původním jazyce

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.
