Electric Barrier for Fish Protection

The Fish Mortality Mitigation and Rescue System for Hydraulic Ducts is an electro-sensitive solution developed for hydroelectric plants and hydraulic systems designed to protect aquatic fauna and reduce fish mortality. The system uses controlled electric fields to prevent fish from approaching turbines and suction ducts, producing a mild stimulus that repels them without causing harm. Operating automatically and continuously, and adapted to the water’s conductivity, the equipment can be installed at intake gates, channels, or suction walls, ensuring efficiency, environmental safety, and compliance with sustainability standards. It is ideal for power utilities and enterprises seeking sustainable technology for environmental mitigation in hydroelectric facilities.
