A new research report has highlighted the significant role regenerative aquaculture can play in addressing environmental challenges such as carbon capture, nutrient mitigation, and marine ecosystem restoration.
The study, released by sustainability consultancy Tunley Environmental in partnership with marine natural capital specialists Algapelago, explores the ecological and economic benefits of large-scale regenerative ocean farming.
At the heart of the research is Algapelago’s Blue Forest project, an initiative that integrates the cultivation of sugar kelp (Saccharina latissima) and blue mussels (Mytilus edulis). By enhancing nutrient cycling, improving water quality, and supporting marine biodiversity, the project aims to provide a scalable solution for sustainable ocean management.
The pilot project is set to deploy an advanced modular cultivation system at Algapelago’s licensed site off the coast of North Devon. The research suggests that, when scaled to 116 hectares, the system could extract between 17.6-21.2 tonnes of nitrogen, 1.0-1.3 tonnes of phosphate, and 195.9-257.5 tonnes of carbon annually. These findings underline the potential of regenerative aquaculture in improving water quality and reducing nutrient pollution.
Dr Nora von Xylander, Marine Biodiversity Specialist at Tunley Environmental and lead author of the report, emphasised the importance of integrating nature-based solutions into marine conservation efforts.
“The Blue Forest project demonstrates how regenerative aquaculture can deliver tangible environmental benefits while supporting the blue economy,” she said. “By harnessing the power of marine ecosystems, we can enhance biodiversity, mitigate climate change, and create sustainable economic opportunities.”
Luke Ansell, Head of Operations at Algapelago, welcomed the findings and their implications for industries seeking effective nutrient mitigation strategies.
“The release of this report showcases the nature-positive potential of the whole Blue Forest project,” Ansell said. “Major industries have been calling for scalable solutions to nutrient pollution, and this research provides a robust baseline to measure the success of our approach.”
The collaboration between Tunley Environmental and Algapelago reflects a shared commitment to tackling climate change and promoting sustainable marine management.
The full report is now available on the Tunley Environmental website, offering valuable insights for policymakers, environmental professionals, and marine conservationists interested in the future of ocean farming.
