    Climate change is a potential threat to the sustainability of aquaculture development. The impact of such can occur as a result of both gradual warming and associated physical changes as well as from frequency, intensity and location of extreme events. It can take place in the context of other global socio-economic pressures on natural resources. Urgent adaptation measures are required in response to opportunities and threats to food and livelihood provision due to climatic variations. The prese nt document briefly analyses the potential impacts of climate change on the aquaculture sector at the global and regional level. Overall, impacts on aquaculture are predicted to vary widely, depending on the current climatic zones of activity. Climate change impacts on aquaculture have both direct effects, e.g. through physical and physiological processes, and indirect effects, e.g. through variations in fish meal supplies and trade issues. Regarding contributions to greenhouse gas (GHG) emissio ns, aquaculture has limited relevance and the primary mitigation route for the sector lies in the reduction of energy consumption, through fuel and raw material use. Options to increase resilience and adaptability include adequate policies and practices with an ecosystem and cross sectoral perspective at regional, national, watershed scales as well as improved management practices at the farm scale.
