Restoring Fish Migration Routes and River Habitats in the Danube Basin

environmentTestedTRL 5

Imagine the Danube river as a giant highway for fish, but with too many road-blocks and potholes. This work identifies where those blocks are and tests ways to clear them so fish can travel and spawn freely. It's like creating a GPS map for nature to ensure river life doesn't disappear.

The business problem

What needed solving

River infrastructure often blocks fish migration, leading to biodiversity loss and regulatory non-compliance. Companies lack a standardized, data-driven map to identify where to implement restoration measures effectively.

The solution

What was built

The project is building the Danube Fish Migration and Connectivity Atlas and a portfolio of nature-based restoration solutions for different river sections.

Who can put this to work

Civil Engineering
enterprise
Target: River infrastructure and dam operators

If you are a dam operator dealing with environmental compliance and fish passage requirements — this project developed nature-based solutions that improve connectivity. These measures help meet restoration targets while maintaining infrastructure functionality.

Environmental Consulting
SME
Target: Ecological assessment firms

If you are a consultancy dealing with habitat mapping for government clients — this project developed the Danube Fish Migration and Connectivity Atlas. This tool allows for precise identification of conservation hotspots to streamline project planning.

Water Management
any
Target: Regional water authority

If you are a water manager dealing with biodiversity loss in tributaries — this project developed a portfolio of tailored solutions for different river sections. This ensures that restoration efforts are matched to local conditions in the Upper, Middle, and Lower Danube.

Frequently asked

Quick answers

What is the cost or price of the developed solutions?

Based on available project data, specific pricing for the solutions is not provided, though the project is supported by a EUR 7,796,074 EU contribution.

Can these solutions be scaled to an industrial level?

Yes, the project specifically includes the development of an action plan and roadmap for the replication and scale-up of solutions across the basin.

How is the IP or licensing handled for the Connectivity Atlas?

Based on available project data, there is no mention of specific licensing terms or patents; the project focuses on knowledge creation and guidelines for replicability.

Which regulations does this project help companies comply with?

The project supports the 'Restore our Ocean and Waters' mission and targets the 25,000 km free-flowing rivers goal.

What is the timeline for implementing these measures?

The project runs from 2025-05-01 to 2029-04-30, during which demonstration activities and action plans will be developed.

Consortium

Who built it

The consortium is heavily weighted toward research and public entities, featuring 41 partners from 11 countries. While universities (7) and research organizations (10) lead the knowledge creation, there is a modest industrial presence with 3 industry partners and 5 SMEs, representing a 7% industry ratio. This suggests the output will be scientifically rigorous but may require further commercial translation.
