Annex XIII: Hydropower & Fish (2013 - Present)
Annex XIII has the broad objective of providing a better understanding of the effects of hydropower on fish. Given the potentially enormous scope of this topic, two main themes have been identified
- fish issues that directly affect hydropower operation and development and how best to manage them
- the impacts of new and existing hydropower development on fish.
With this in mind, the Annex participants have agreed that fish migration in a wide sense be the main topic for further research with a special report on efficient two-way fish migration in regulated rivers.
- A fish migration report with two main elements: technology development and important issues for a protocol on fish passage.
- A report on best practices for fish management.
- A separate summary report is being considered in relation to the EU's Water Framework Directive

1. A fish migration report will have two main elements, technology development and important issues for a protocol on fish passage.
- Technology development will cover monitoring techniques such as sensor fish and fish passage routes including through turbine waterways
- The protocol will include licensing/re-licensing, verification of passage efficiency and cost benefit assessments. The report will serve as a toolbox and guideline for the member institutions and decision-makers in general.
2. A second important task will be focussed on fish management. This will include issues such as principles for sustainable fish management, effective measures for fish protection and an overview of regulatory regimes, for example those of the EU under the Water Framework Directive, and more generally, effective management models.
