Renewable Energy and Digital Tools to Lower Fish Farming Operating Costs

foodPilotedTRL 6

Imagine running a fish farm where the electricity for pumps and heaters comes from the sun and wind instead of expensive power grids. It's like adding a smart brain to the farm that automatically manages feeding and water quality to stop waste. This helps fish farmers stop worrying about rising energy bills and unpredictable weather.

The business problem

What needed solving

Aquaculture farms face unsustainable energy costs and climate pressures, relying heavily on expensive fossil fuels for critical operations like pumping and heating.

The solution

What was built

Integrated renewable energy systems (floating PV, wind, biogas) and precision digital tools for feeding and water quality management.

Target: Commercial fish farm operator

If you are a fish farm operator dealing with high energy costs for pumping and aeration — this project developed integrated renewable energy sources and Energy Management Systems that lower dependence on fossil fuels.

Agri-Tech
SME
Target: Precision farming software provider

If you are a software provider dealing with a lack of species-specific data — this project developed precision digital tools for feeding and water quality tailored to carp, trout, and African catfish.

Renewable Energy
mid-size
Target: Floating solar and wind installer

If you are an energy installer dealing with niche market entry — this project developed floating PV and wind solutions specifically integrated into aquaculture environments across 7 demonstration sites.

Frequently asked

Quick answers

How will this reduce operational costs?

The project targets energy, which is the second largest cost after feed, by replacing fossil fuels with floating PV, wind, geothermal, biogas, and waste heat.

Is this tested at an industrial scale?

Yes, the solutions are being validated in real farm conditions across 7 demonstration sites in Hungary, Romania, Austria, Slovakia, and the Czech Republic.

What are the IP and licensing options?

Based on available project data, the project uses open science practices and a co-created Data Management Plan to make results transparent and reproducible.

Which specific fish species are covered?

The innovations are tailored for carp, trout, and African catfish production, as well as Black Sea trout cages.

When will the results be available?

The project period runs from 2026-09-01 to 2029-08-31.

Consortium

Who built it

The consortium is heavily weighted toward practical application, with 30% industry participation including 5 SMEs. With 20 partners across 10 countries, the project balances academic research (2 universities, 5 research institutes) with 7 other organizational entities, ensuring the tools are designed for actual farmers rather than just labs.
