Electric Fish Protection Systems
Electric Fish Protection Systems work by generating an electric field that affects the nervous and muscular systems of fish. This field causes the fish to change their swimming direction and avoid dangerous areas, such as turbines or water intake points. The system uses low-voltage impulses, which are adjusted in terms of intensity and frequency to ensure they are harmless to fish and other aquatic organisms. No injuries or reproductive issues occur as a result of the field.
We act as the exclusive distributor for the manufacturer of the “NEPTUN” electric fish protection system in Germany, Austria, and Switzerland. We offer comprehensive consulting, collaborate closely with experts from Procom Systems, and provide tailored fish guidance systems that perfectly meet your individual requirements.
Fish Protection
NEPTUN - Electric Fish Protection System
The electric field is created between positively and negatively charged electrodes, which are installed at a safe distance from the hazardous areas. This setup gives fish enough time and strength to react. Such systems are particularly useful at hydropower plants, water intake points, and for managing invasive fish species. They help guide fish into safe zones like fish ladders or bypass channels, which reduces mortality and population decline in vulnerable fish stocks. Additionally, these systems can lower the operational and maintenance costs of the installations.
Advantages:
- Easy Installation and Retrofitting on Existing and Newly Built Systems
- No restriction on shipping
- No impact on the drop height
- Resistant to mechanical damage (e.g., debris)
- Resistant to freezing
- Low energy consumption
- High safety aspect due to operation in the low voltage range with direct current
Examples
NEPTUN
Fish protection at weirs and hydropower plants
A NEPTUN fish guidance system installed in the upstream area prevents fish from entering turbines by guiding them to a safe path via a bypass or fish passage system.
A NEPTUN system installed downstream protects migrating fish from entering the fast-flowing, oxygen-rich turbine outlets and instead directs them into fish passes.
NEPTUN
Protection of technical installations
The NEPTUN fish guidance system plays a crucial role in protecting technical installations that require water from surface water bodies, such as for cooling power plants or extracting process water. Traditional systems often result in numerous animals dying in pumps, which is not only ethically concerning but also leads to significant cleaning and maintenance efforts.
Thanks to the NEPTUN fish guidance system, both fish and technical installations are effectively protected.
NEPTUN
Protection of water bodies with migration barriers
The NEPTUN system can also be used as a migration barrier. This helps prevent invasive species from entering sensitive aquatic ecosystems or protects fish farms from predators.
