The solution for ascending river wildlife
The FAS (Fish Ascending Screw System REHART/Strasser) is the space-saving and cost-effective alternative to a conventional fishway. In a new installation, the FAS is placed on the side next to the hydropower screw. Of course, the FAS can be retrofitted to an existing hydropower screw, this is also possible next to a turbine without any problems.
The slowly rotating FAS is safely detectable for fish and other bottom-oriented aquatic animals due to the generated attracting current. The size of the tube and the auger are individually designed for the occurring fish species. Even for weakly swimming fish and other river inhabitants such as crayfish or insect larvae, the ascent is possible without any problems, which is impressively proven by excellent monitoring results.
The safe descent is, as with all plants from
REHARTPOWER, by means of the hydrodynamic screw.
