The revised Water Protection Act requires the restoration of fish migration in watercourses as part of sustainable water management. Protective hydraulic engineering barriers and obstacles at hydroelectric power plants are to be equipped with fishways. Straub AG, a subsidiary of PINI, is an expert in this field and develops optimum solutions specifically designed for the locations in question, ranging from fish ladders, locks and ramps to fish lifts. Good cooperation with power plant operators, municipalities and authorities is crucial. The picture shows the Champfèr barrage near St. Moritz. Solution: conventional fish ladder.
