As a result of intensive and ongoing discussions in the German Participatory Forum on Fish Protection and Downstream Migration, a mutual understanding was reached in 2014, up to which screen size a functioning mechanical fish protection and bypass system including the necessary cleaning technology can be realised. With vertical screens (up to approx. 30 m³/s per screen) and horizontal screens (up to approx. 50 m³/s per screen) there is currently a state of knowledge and technology with which functional, mechanical fish protection and bypass systems, including the necessary cleaning technology, can be realised for fish larger than 10 cm. The infographic is part of the fact sheet "Technical Functionality of Large Fish Protection Screens Confirmed in Practice."
