The functional components of a fish protection system
The key messages of Fact Sheet No. 05 are:
- A fish protection system must provide three functions: Blocking, guiding and transferring.
- Fish protection screens and bypasses form a functional unit in fish protection systems. Screens without bypasses or bypasses without a suitable screen do not constitute a protection system.
- Horizontally angled fish protection screens guide fish across the entire water column to the bypass. The fish can remain in their natural swimming horizon.
- Vertically angled fish protection screens can guide fish to bypass inlets or collection devices near the surface across the entire width of the turbine inlet.
