The economic impacts of ocean acidification on shellfish fisheries and aquaculture in the United Kingdom
Ocean acidification may pose a major threat to commercial fisheries, especially those for calcifying shellfish species. This study was undertaken to estimate the potential economic costs resulting from ocean acidification on UK wild capture and aquaculture shellfish production. Applying the net pres...
