Expertise transfer Paraguay – Austria

Their Excellencies, Cesar Ariel Oviedo Verdún (Minister of Environment of Paraguay) as well as the Paraguayan Ambassador and former Minister of Environment Dr. Juan Francisco Facetti, were received to exchange experiences in Vienna! The City of Vienna / Wiener Gewässer and DWS Hydro-Ökologie reported on the condition, development and in particular the restoration of the Old Danube.

An inspiring and constructive exchange!

During an electric fishing campaign at the end of August in the framework of the EU-INTERREG project REBEN an astonishingly rich variety of species could be detected: from typical lake species such as rudd and whute bream on stagnophile specialists such as European weatherfish, crucian carp, tench and European bitterling to running water species such as chub.
