This Fact Sheet provides methodological recommendations for quantifying the risk of harm and mortality to fish during passage from hydropower sites. The fact sheet "Evaluation of primary injury to fish at hydropower sites" is available for download.

In 2014, the German Participatory Forum on Fish Protection and Downstream Migration 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 German Participatory Forum on Fish Protection and Downstream Migration is confirmed in the actual operation of existing fish protection screens. Fact Sheet 04 "Technical functionality of large fish protection screens confirmed in practice" is available for download.

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 "What makes a screen to a fish protection screen" 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.

The 2-day workshop, funded within the framework of the BMU’s (Federal Ministry for the Environment, Nature Conservation and Nuclear Safety) Environmental Research Plan, took place from 3 to 4 December 2019 in Augsburg at the Bavarian State Office for the Environment.

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 is updated and improved. Additionally in this project, the fourth UBA Hydromorphology Workshop is organised.

During the first period of the Forum Fish Protection and Downstream Fish Migration, more than 200 people from different fields, such as water management and nature conservation by the states and the federal government, the federal waterway administration and transport development, the energy industry, the water engineering, fishery biology, nature conservation, fishery and fishery associations and the university science were involved. In the second cycle of the Forum from 2015 to 2018, three two-day events were held to deepen the statements of the first cycle and to continue the constructive dialogue.

The Federal Environment Agency (UBA) organized the forum on Fish Protection and Downstream Fish Migration for three years as part of an R&D project of the Environmental Research Plan of the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU). Ecologic Institute provided content and organizational support for the forum on behalf of the Federal Environment Agency. The forum included members from federal and regional water resource management authorities, NGOs, consultancies, water managers and hydropower.
