Adaptive Management Strategies to Protect River Fish from Predation Pressure

environmentPrototypeTRL 3Thin data (2/5)

Imagine a river where the fish are disappearing because too many birds are eating them. This project studies the battle between cormorants and grayling fish to find a fair balance. It's like figuring out how to keep the forest healthy without letting one animal wipe out another.

The business problem

What needed solving

River fish populations are crashing due to predation and pollution, leading to intense conflicts between wildlife managers and local stakeholders. There is a critical lack of published scientific data to resolve these disputes and protect endangered species.

The solution

What was built

A network of field experiments and a literature review (D 4.1) to generate management recommendations for river biodiversity.

Who can put this to work

Environmental Consulting
SME
Target: Biodiversity Assessment Firm

If you are a biodiversity assessment firm dealing with declining river fish populations — this project developed knowledge-based recommendations that help implement adaptive nature management. This allows for more accurate reporting on the conservation status of EU-listed species.

Water Management
enterprise
Target: River Basin Authority

If you are a river basin authority dealing with conflicts between bird protection and fish conservation — this project developed tested protective actions and culling data. This provides a scientific basis to reduce local conflicts over predation pressure.

Fisheries Management
mid-size
Target: Commercial Fish Hatchery or Stocking Service

If you are a stocking service dealing with high mortality rates of released grayling — this project developed field experiments to measure the effect of relieving predation. This helps in optimizing the survival rates of protected fish species.

Frequently asked

Quick answers

What is the cost or price of implementing these recommendations?

Based on available project data, no specific pricing or implementation costs are provided; the project focuses on generating management recommendations.

Can these methods be scaled to an industrial level?

The project uses EU-wide data and field experiments across 8 countries, suggesting the recommendations are designed for broad regional application rather than a single industrial plant.

Is there any IP or licensing available for the protective actions?

Based on available project data, the outputs are management recommendations and scientific knowledge; no specific patents or licenses are mentioned.

How does this project align with EU regulations?

The project directly supports the EU Biodiversity Strategy, Natura 2000, the Water Framework Directive (WFD), and the Habitats and Birds Directives.

What is the timeline for the results?

The project runs from 2024-06-01 to 2028-05-31, with initial infrastructure and experiments established in the first 18 months.

Consortium

Who built it

The consortium is heavily weighted toward research and academia, with 5 universities and 4 research institutions. Only 1 industry partner (SME) is involved, representing a 10% industry ratio. This indicates the project is primarily driven by scientific discovery and policy recommendations rather than immediate commercial product development.
