Eel ladders
The natural recruitment of eel stocks in rivers is prevented by numerous impassable barriers. However, glass eels and elvers can migrate upstream via special eel ladders. The Institut für angewandte Ökologie GmbH has experience positioning the entrance of a fish pass correctly and to operate such facilities properly. In addition, we have a mobile eel ladder in order to find a potential upstream migration corridor at a dam.
