This fact sheet examines the functional elements of a fish protection system and explains when a rake is a fish protection rake. The fact sheet "Wann ist ein Rechen ein Fischschutzrechen? (When is a rake a fish protection rake?)" is available for download.

In 2014, the "Forum Fischschutz und Fischabstieg" was able to develop a common understanding of the size of a screen up to which functioning mechanical fish protection and descent systems, including the necessary cleaning technology, can be implemented. The objective of the research underlying this Fact Sheet 04 was to verify whether the statement of the "Forum Fischschutz und Fischabstieg" is confirmed in the actual operation of existing fish protection screens. Fact Sheet 04 "Technische Funktionsfähigkeit großer Fischschutzrechen in der Praxis bestätigt (Technical functionality of large fish protection screens confirmed in practice)" is available for download.

To achieve climate neutrality by 2050, EU policy will have to be reoriented – from incremental towards structural change. As expressed in the European Green Deal, the challenge is to initiate the necessary transformation to climate neutrality in the coming years, while enhancing competitiveness, productivity, employment. To mobilise the creative, financial and political resources, the EU also needs a governance framework that facilitates cross-sectoral policy integration and that allows citizens, public and private stakeholders to participate in the process and to own the results.

With the aim of achieving "good ecological status" in all water bodies by 2015, the Water Framework Directive requires Member States to put more emphasis on hydromorphological issues and watercourse connectivity for the conservation and restoration of fish populations. The aim for the third cycle of the "Forum Fish Protection and Downstream Migration" is to continue the series of workshops on fish protection and downstream migration and to evaluate them in papers, reports and publications. In addition, the website forum-fischschutz.de will be updated and improved. In this project, the fourth UBA Hydromorphology Workshop will also be organised.

The RECIPES project (REconciling sCience, Innovation and Precaution through the Engagement of Stakeholders) aims to develop new tools and guidelines to ensure the precautionary principle is applied while still encouraging innovation. RECIPES will consider a number of concerns and broaden the basis of participation by engaging with citizens and stakeholders in the co-creation of new tools for innovation and precaution. The objective is to address and reduce societal controversy while helping policymakers and other stakeholders to assess risks and uncertainty and applying the precautionary principle taking into account innovation.
