In this report a fish species classification system according to their species-specific sensitivity against mortality was developed to assess the impacts of hydropower plants on fish species more effectively. The compiled metadata overview comprises 192 fish and lamprey species that are classified according to their sensitivity against mortality. The result allows for an objective and comprehensible comparison of the inherent biological sensitivity of fish and lamprey species and identified in total 40 taxa of high susceptibility to disturbance covering all biogeographic regions of Europe.
FIThydro Deliverable 1.2
Risk classification of European lampreys and fish species
31 October 2018 | Lead: TUM, FVB.IGB
This publication characterises the potential impacts of hydropower on fish. The principal operation related impacts of hydropower are analysed and species most at risk are identified. The resulting sensitivity matrix contains 148 native European fish and lamprey species.
Assessing the impact of hydropower plants (HPP) on different fish species and communities is a key-component supporting decisions during the commissioning process and operation of HPPs. The Fish Population Hazard Index presented in this publication is a decision and management tool for environmental impact assessment of hydropower plants. The index allows risk assessment while considering site-specific effects of single hydropower plants, fish species sensitivity against mortality as well as overarching environmental and societal development targets for the respective water body.
FIThydro Deliverable 2.1
A List of solutions, models, tools and devices, their application range on a regional and overall level, the identified knowledge gaps and the recommendations to fill these
31 October 2018 | Lead: CNRS
For a comprehensive assessment of self-sustained fish populations affected by hydropower, existing solutions, methods, tools and devices (SMTDs) are identified and described. The topics addressed are: upstream and downstream migration, turbines, hydromorphology, hydropeaking, e-flows, fish characterisation and habitat. Additionally, the research conducted at 13 Test Cases (hydropower plants) of FIThydro across Europe is presented.
FIThydro Deliverable 2.2
Working basis of solutions, models, tools and devices and identification of their application range on a regional and overall level to attain self-sustained fish populations
30 April 2019 | Lead: CNRS
This publication provides an overview of the solutions, methods, tools and devices (SMTDs) in the FIThydro project. It is based on the analysis and experiences of the presently available SMTDs tested and applied in 14 FIThydro Test Cases and in lab investigations. 32 different SMTDs are described, the results of their use at the Test Cases are provided and their application and usability for upstream and downstream migration, passage through turbines, hydropeaking and hydromorphology are discussed.
One way of fish downstream migration is passage through the turbine at hydropower installations, which can be related to injury and mortality, caused by several damage mechanisms. This guideline presents both basic and more detailed methods to quantitatively assess the fish passage through a hydropower turbine.
FIThydro Deliverable 4.1
A classification system for methods, tools and measures for improvements measures
31 October 2018 | Lead: Sintef
The report describes the main types of mitigation measures for hydropower impacts that can be used to solve challenges related to: environmental flows, habitat, sediment management, upstream and downstream migration. For each type of mitigation measures, several solutions are described.
FIThydro Deliverable 4.2
Functional application matrix for identification of potential combinations of improvements measures
31 October 2019 | Lead: Sintef
Possible mitigation measures for mitigating the impacts of hydropower on fish are scored with respect to their suitability for mitigating challenges and problems. A matrix also shows how different mitigation measures can be combined. Additionally, the framework for using Bayesian networks to identify potential combinations of mitigation measures is described.
This report investigates and summarises the regulatory landscape influencing actions relevant to environmental improvements in the context of planning and operating hydropower plants on a European and national level. Emphasis is given to the requirements of the EU Water Framework Directive, nature protection policies and policies on renewable energy and climate change adaptation, thereby outlining opportunities, barriers and challenges in reaching multiple environmental objectives. Next to EU legislations, national policies of eight European countries are reviewed. Additionally, the use of financing instruments in different EU countries for providing the necessary support to promote and sustain ecologically compatible hydropower production are looked into.

Stakeholder feedback on tools and products of FIThydro
31 October 2019 | Lead: EI
In 2018, the Horizon2020 project FIThydro, Fishfriendly Innovative Technologies for Hydropower, hosted regional stakeholder workshops in four test case regions, with different geographical, climatic and hydropower-related characteristics across Europe. The workshops offered a platform for consultation and exchange between FIThydro members and external stakeholders on the key open issues on important questions relevant to the assessment and planning of fish-friendly hydropower plants. This report summaries the feedback received from the stakeholders during the four regional stakeholder workshop on: key problems and open questions for the assessment and planning of fish-friendly hydropower production, typical approaches and applied solutions as well as recommendations and requests to the FIThydro project.
FIThydro Deliverable 5.3
Public acceptance of alternative hydropower solutions
31 October 2019 | Lead: EI
This report presents results from four European case studies on the public acceptance of hydropower. Q-methodology was used as a means to identify public perceptions and preferences on the modernization, expansion or conversion of hydropower facilities in Europe.
Upcoming Technical Deliverables
The FIThydro project will produce the following public reports. They will be made available here.
