| Summary: | No abstracts are to be cited without prior reference to the author.Evidence indicates that absorption of atmospheric carbon dioxide (CO2) in the ocean has already decreased pH levels by 0.1 pH units since 1750, and CO2 concentrations are projected to rise further by the end of the century as fossil fuel reserves continue to be exploited. To date, a large proportion of ocean acidification (OA) research undertaken has tended to concentrate on benthic or planktonic species which are of limited direct importance to fisheries and aquaculture. Furthermore, some of the available evidence is contradictory with some studies demonstrating that species are robust to lower pH whilst others show marked sensitivity. There is still much research needed to understand some of the observed organisms’ responses to changes in pH under laboratory and under their natural environment. In the UK, fisheries generate more than £800 million of revenue per year and support 30,000 jobs. Aquaculture generates £350 million and supports a ... |
