Integrating Food Systems, Conservation, and the Future of the Blue Economy

Aquaculture is undergoing a profound transformation. Beyond supplying food to a growing global population, emerging evidence shows that aquaculture can actively restore degraded marine ecosystems, support the recovery of threatened species, and contribute to international biodiversity targets. A new open-access paper published in Aquaculture Research explores this paradigm shift, presenting aquaculture-assisted ecological restoration as a powerful approach to scale up restoration actions and reduce pressure on natural populations.

The publication highlights how mariculture practices — particularly Integrated Multi-Trophic Aquaculture (IMTA) — can be designed not only to mitigate environmental impacts but also to generate positive ecological outcomes. By cultivating marine species of conservation interest (such as habitat-forming seaweeds, seagrasses, and endangered invertebrates) alongside commercial species, aquaculture facilities can simultaneously produce food, enhance ecosystem functions, and support large-scale restoration efforts.

This demonstration shows the unique potential of aquaculture environments to act as mid-stage nurseries for species of conservation interest:

• enabling juveniles to reach refuge size,
• increasing genetic variability through controlled reproduction,
• reducing the ecological cost associated with wild donor populations,
• and dramatically scaling up restoration capabilities.

The approaches followed for the research activities align closely with EU and global policy frameworks, including the EU Biodiversity Strategy 2030, the EU Nature Restoration Regulation, and the Kunming-Montreal Global Biodiversity Framework, all calling for large-scale intervention and innovative restoration pathways.

The study concludes that integrating conservation-oriented culturing within commercial aquaculture is not merely feasible — it is a necessary evolution. This combined model:

• strengthens ecosystem resilience,
• reduces operational costs compared to laboratory-only cultivation,
• creates new economic opportunities (e.g., biodiversity nurseries, restoration supply chains, blue jobs),
• and positions aquaculture as an active agent in ecosystem rehabilitation, not just a food production industry.

For NOVAFOODIES, this work reinforces the project’s mission to develop innovative, sustainable, and biodiversity-positive food systems. The integration of ecological restoration into aquaculture practices stands as a core pillar of the future blue economy.
