A consortium of scientists from Germany, Italy, and Lithuania has embarked on a groundbreaking transnational research project, ProRMAS. Funded by the Green ERA-Hub (GEH), they aim to develop a recirculating multitrophic aquaponic system (RMAS) for production of valuable proteins and organic fertilizers from saline water sources.
With seafood supply currently reaching around 17% of animal proteins and about 7% of total protein, recirculating aquaculture systems (RAS) has potential for growth in the upcoming years. However, nutrients in the dissolved and solid waste from these systems remain unused. Here ProRMAS team comes with the innovative solution: integrating aquatic species, filter feeders, and plants into a fully circular system using saline water.
“Our goal is to develop a sustainable, closed-loop system that maximizes water and nutrient efficiency while producing high-quality protein,” said Matthew James Slater, Head of Aquaculture Research Group at Alfred Wegener Institute, and leader of the international ProRMAS consortium. “By utilizing saline water resources, we can create a viable solution for food production in areas where freshwater is scarce.”
Researchers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (Germany), Department of Agronomy, Food, Natural resources, Animals and Environment (DAFNAE) at the University of Padova (Italy), and Klaipėda Science and Technology Park (Lithuania), are conducting multiple experiments and tests with sludge from the shrimp cultivation to produce aquatic species that can be used in novel shrimp diets.
Focusing on cultivating shrimp as a high-value protein, the innovative system will produce polychaetes to serve as an alternative to fishmeal in feeds, while also recovering nutrients and reducing organic waste through remineralization. Halophyte plants and macroalgae will absorb dissolved nutrients and can be utilized in feed and for human consumption due to their nutritional properties. Any remaining organic residue will be converted into bio-fertilizers for use in soil and soilless vegetable cultivation, aiming for zero waste and nutrient loss.
In cooperation with the greenhub solutions GmbH, providers of innovative vertical farming solutions, a future demo-farm is being designed. Located in Germany, it will integrate the production of shrimp, polychaetes, Ulva spp., halophytes, and traditional vegetable species. The complete demo-farm will serve as a base to evaluate the environmental impact, economic viability, and quality of food production.

The ProRMAS project is carried out under the Green ERA-Hub, a Coordination and Support Action (CSA), funded through the European Union’s Horizon Europe research and innovation (R&I) programme under Grant Agreement No. 101056828.
This international research and development project is supported by the Ministry of Agriculture of the Republic of Lithuania, the Federal Ministry of Education and Research of the Federal Republic of Germany, and the Ministry of Agriculture, Food Sovereignty and Forestry of the Republic of Italy.
Researchers from Germany, Italy, and Lithuania have joined forces in the international research project ProRMAS, funded by Green ERA-Hub. Project partners are developing an innovative system to produce valuable proteins and organic fertilizers from saline water sources using a recirculating multitrophic aquaponic system (RMAS).
Last week, the project consortium, uniting researchers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, University of Padova, Klaipėda Science and Technology Park, and representatives of greenhub solutions GmbH, a company developing advanced solutions for vertical farming, held a meeting in Padova, Italy.
During the meeting, we shared updates on ongoing experiments and activities, reviewing the progress made in creating a novel food production system that integrates the cultivation of shrimp, polychaetes, seaweed, and halophytes into one closed-loop cycle using saline water.
Part of the visit was dedicated to exploring our partners’ scientific facilities. We visited the Department of Agronomy, Food, Natural Resources, Animals, and Environment (DAFNAE) at the University of Padova, which will host one of the ProRMAS pilot systems.

On October 10-11, ProRMAS project team participated in the Joint Programming Initiative on Agriculture, Food Security, and Climate Change (FACCE-JPI) and Green ERA-Hub (GEH) joint conference Towards New Horizons – Sustainable solutions in Agri-Food and Biotechnology in Berlin, where 17 transnational research projects funded by GEH were presented.
The event brought together researchers, policymakers, funding agencies, and various initiatives from the EU and beyond. Focused on sustainable agriculture, food security, and biotechnology, the conference served as a platform to highlight innovative initiatives aimed at reducing environmental impacts by leveraging natural, eco-friendly methods in agriculture and environmental management.
During the conference, Isabela Pinheiro, researcher at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, presented ProRMAS project and its vision of producing valuable proteins and organic fertilizers from saline water sources using a recirculating multitrophic aquaponic system (RMAS). The interactive sessions provided an excellent opportunity to share insights and explore potential collaborations with other research initiatives.
