Aquaculture, including marine aquaculture (mariculture), is the fastest growing food production
sector globally and is expected to play a key role in delivering future food security. A potential factor
limiting growth of the aquaculture industry, however, is the maintenance of good water quality, on
which all forms of aquaculture depend. This is particularly challenging in ‘open’ coastal and estuarine
systems and requires engagement with a wide range of stakeholders that can influence water quality.
We applied a semi-quantitative method (Q-method) to capture and evaluate perspectives across
diverse stakeholders in order to address the overarching question: “How do stakeholders rank water
quality issues and management options versus other issues and actions for ensuring the sustainability
of shellfish mariculture in South West England?” Results from this regional case study were used to
highlight key issues and knowledge gaps that have national and international relevance. Stakeholders
were found to hold distinct perspectives (P1-3), but there was general consensus that good water
quality is essential for sustainable aquaculture, and that there is a need for better understanding of
spatial and temporal variations in land use throughout catchments to ensure effective water quality
management. Stakeholder engagement highlighted the importance of managing anthropogenic and
environmental (climatic) pressures on land and water through agri-environment and urban planning
policy in order to ensure sustainable food production, including from mariculture
