Abstract: The flexible fish fence consists of horizontally clamped steel ropes. It is placed in front of the intakes to the turbines of hydropower plants and arranged in a way that it directs the fish towards a downstream fish passage facility. The electrified flexible fish fence is a significant advancement to the original prototype, as the steel ropes are used as electrodes to create an electrical field. The electrified version of the flexible fish fence is functioning as a guiding system to prevent fish from entering turbines and to guide downstream migrating fish towards a downstream passage facility. Therefore, it combines both, a mechanical as well as a behavioral barrier and guiding system
