The state of the art in construction offish passes in Austria is defined in an administrative order of the Federal Ministry of Agriculture, Forestry, Environment and Water Management of Austria 2012. Since 2009 the federal state of Salzburg has a checklist for such ecologically constructions. The following report deals now with the question when is a new-built fish pass state of the art or not.


The obligation to preserve or restore the good ecological status of freshwater systems for fish has also accelerated the construction offish passes in Austria. Due to the call for the ecological reconnection of habitats especially for mid-distance migratory fish, the knowledge about the ecological and technical requirements offish passes needs to be updated and distributed in Austria. The fundamentals of the Austrian guideline for fish pass construction constitute an important basis for it.
