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.

Ecologic Institute coordinated the organisation of the 9th Workshop on Fish Protection and Downstream Migration, dedicated to the topic of "Technical-Hydraulic Assessment of Fish Protection and Downstream Migration at Hydropower Plants". A programme flyer were developed and designed to provide relevant content on conference context, agenda, and the venue in a concerted way to participants.

The two-day workshop, funded under the BMUV's Environmental Research Plan, took place on 30 and 31 May 2022 at the Federal Environment Agency in Dessau (Germany) and was dedicated to the topic of "Technical-Hydraulic Assessment of Fish Protection and Downstream Migration at Hydropower Plants".

Since 2012, more than 200 experts from various fields of water management and nature conservation, the federal states and the federal government, the federal waterway administration, the energy industry, hydraulic engineering, fisheries biology, nature conservation, fishing and fishing associations and university science have been involved in the German Participatory Forum on Fish Protection and Downstream Migration. In the second cycle of the Forum, from 2015 to 2018, the productive dialogue was continued and a better understanding or various aspects of fish protection and downstream fish migration was compiled. This report documents the project work of the 2nd cycle and is available for download.

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.

In April 2018, the second cycle of the Forum "Fish Protection and Downstream Migration" ended, which was devoted, among other things, to improving the implementation of measures. In this article, the authors, among them Dr. Ulf Stein of Ecologic Institute, summarize the intensive discourse between all stakeholders over the past six years and present the resulting twelve recommendations. The recommendations describe how to proceed with this topic in the future and how to avoid potential conflicts in practice. The article is published in WasserWirtschaft, Issue 06/2018, Springer Vieweg.

The 7th workshop of the forum "Fish Protection and Downstream Migration" was dedicated to the topic of improving the implementation of measures at the end of the second cycle of the forum. The workshop took place in Dresden in April 2018. Important to this workshop was the task of creating a summary of the intense discourse that had taken place between all of the stakeholders over the past six years. These discourses were then synthesized into twelve guidelines. The recommendations and results of the event are available for download.

<p>The conference was in line with the thematic approach of the Forum, but took also into account the need for professional development. The conference focused on presenting and discussing current research and development projects from Germany, Austria and Switzerland.</p>&#13;&#13;

<p>The sixth workshop of the Forum was marked by the beginning of the 2nd management cycle of the Water Framework Directive. At the event, the results of the first management cycle with regard to the status of the fish fauna and the envisaged measures to improve this quality element were reflected. In this context, the assessment methods for the fish fauna in surface water bodies and the passability of barriers and the resulting measures were considered.</p>&#13;&#13;

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.

A newly created atlas for fish protection and downstream fish migration ("Atlas Fischschutz & Fischabstieg"), designed and implemented by Ecologic Institute, is online since June 2016. The map indicates all the locations of measures for fish protection and downstream fish migration complemented by information taken from associated studies. Furthermore, the filter function highlights specific research and development projects as well as information regarding specific basics and activities. Stakeholders in terms of fish protection and downstream fish migration are invited to add new content to the atlas.

The German Federal Agency of Environment (UBA) published a synthesis report. The report summarizes major findings of the research and discussions undertaken in the German Forum on Fish Protection and Downstream Fish Migration in which the Ecologic Institute played a major role. The report highlights remaining research and development needs that require further investigation and discussion. It is available for download.
