1. Marine aquaculture relies on coastal habitats that will be affected by climate change. This review assessescurrent knowledge of the threats and opportunities of climate change for aquaculture in the UK and Ireland,focusing on the most commonly farmed species, blue mussels (Mytilus edulis) and Atlantic salmon (Salmo salar).2. There is sparse evidence to indicate that climate change is affecting aquaculture in the UK and Ireland.Impacts to date have been difficult to discern from natural environmental variability, and the pace oftechnological development in aquaculture overshadows effects of climatic change. However, this review ofbroader aquaculture literature and the likely effects of climate change suggests that over the next century,climate change has the potential to directly impact the industry.3. Impacts are related to the industry’s dependence on the marine environment for suitable biophysicalconditions. For instance, changes in the frequency and strength of storms pose a risk to infrastructure, such assalmon cages. Sea-level rise will shift shoreline morphology, reducing the areal extent of some habitats that aresuitable for the industry. Changes in rainfall patterns will increase the turbidity and nutrient loading of rivers,potentially triggering harmful algal blooms and negatively affecting bivalve farming. In addition, oceanacidification may disrupt the early developmental stages of shellfish.4. Some of the most damaging but least predictable effects of climate change relate to the emergence, translocationand virulence of diseases, parasites and pathogens, although parasites and diseases in finfish aquaculture may becontrolled through intervention. The spread of nuisance and non-native species is also potentially damaging.5. Rising temperatures may create the opportunity to rear warmer water species in theUKand Ireland. Market forces,rather than technical feasibility, are likely to determine whether existing farmed species are displaced by new ones.
