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.

The central objective of the Hydromorphology IV Workshop was to exchange experiences and information and to identify and reflect on challenges of the administrative and practical implementation processes of watercourse development measures.

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.
