Bivalve aquaculture is increasingly being explored not only as a source of sustainable seafood, but also as part of a broader conversation about ecosystem services and coastal resilience. Emerging research in the United Kingdom is helping quantify how shellfish species such as mussels, oysters and clams remove nutrients from marine environments through natural biological processes, creating opportunities to better understand aquaculture’s role in supporting water quality and environmental management.

At the same time, this work emphasizes the importance of realism and balance. Nutrient removal through shellfish farming is not a replacement for traditional water treatment or a universal solution to eutrophication, but it may become one tool within a larger portfolio of approaches. The discussion explores how science, industry, policymakers and growers can collaborate to better measure environmental outcomes while continuing to strengthen seafood production, ecosystem health and long-term resilience.

• Shellfish aquaculture can provide benefits beyond food production.
• Bivalves improve water quality through natural filter-feeding processes.
• Nutrient removal performance varies by species, location and cultivation method.
• Ecosystem services require careful measurement to avoid oversimplification.
• Environmental value and commercial viability must remain aligned.
• Collaboration across industry, science and policy is essential.
• Incremental solutions can still make meaningful contributions to marine health.
