The issue of fish protection and downstream fish migration is discussed intensively - even controversially - between and within the individual disciplines and areas of competence, both from a technical and an environmental policy perspective. The German Participatory Forum on Fish Protection and Downstream Migration has been dedicated to this discussion since 2012. This report, which concludes the German Participatory Forum on Fish Protection and Downstream Migration summarizes a selection of key issues from the forum's workshops across six central topics.

This infographic shows, color-coded for the three developmental stages of domestic fish, body proportion-based bar spacing of rakes that can prevent fish from swimming into the high-risk areas.

This report summarizes the results of the Hydromorphology workshop series (2008, 2012, 2016, 2021) of the German Federal Environment Agency in the form of a synthesis.

The illustration exemplifies the derivation of the study parameters in field studies for the determination of the site injury rate. It is part of a fact sheet on fish protection and downstream fish migration measures.

This illustration shows the group and individual approach to quantifying passage-related injuries at a hydropower site. It is part of a fact sheet on primary injury to fish at hydropower sites.

This illustration shows a comparison of the injuries of a common Nase before and after the passage of a hydropower site. It is part of a fact sheet on primary injury to fish at hydropower sites.

This illustration shows advantages and disadvantages of using naturally downstream migrating fish or an experimental approach to determine the mortality and injury risk. It is part of a fact sheet on primary injury to fish at hydropower sites.

This infographic provides an overview of the Measures for fish protection and downstream fish migration in Europe. The infographic is part of a fact sheet on fish protection targets in Europe.

This infographic provides an overview of the prevalence of strategic concepts for hydropower utilisation and general methods or recommendations for ensuring downstream continuity in Europe. The infographic is part of a fact sheet on fish protection targets in Europe.

This infographic presents the key data of the screen systems at the Willstätt, Unkelmühle, Kemnade and Öblitz hydropower sites. The infographic is part of the fact sheet "Technical Functionality of Large Fish Protection Screens Confirmed in Practice."

This infographic summarizes the information on build-out flow and bypass flow at sites entered in the Atlas Fish Protection & Downstream Fish. The proportionate flow rate corresponds to the percentage of the bypass flow rate in relation to the development flow rate. The infographic is part of a fact sheet on fish protection and downstream fish migration measures.

This infographic evaluates the information on the aspects of the monitoring studies (multiple answers possible) at the sites entered in the Atlas of Fish Protection & Downstream Fishways. The infographic is part of a fact sheet on fish protection and downstream fish migration measures.

This infographic summarizes the data on the monitoring studies, differentiated by screen bar spacing and build-out flow rate at the sites entered in the Atlas Fish Protection & Downstream Fish up to a build-out flow rate of 200 m³/s. The infographic is part of a fact sheet on fish protection and downstream fish migration measures.
