ABSTRACT
Aquaculture production is closely linked to the environment, as discussed in the previous two chapters. Chapter 6 examines how climate change – referring to changes in global weather patterns – can affect aquaculture. However, it is important to note that the environmental impacts of aquaculture can aggravate the risks associated with climate change. Climate change is not limited to temperature increases; it is a complex phenomenon that can have various effects, including ocean acidification, more frequent red tides, and an increase in severe climate meteorological events. Some of these effects can have physical, chemical, and biological impacts, while others can increase aquaculture risks, such as power outages, damaged infrastructure, and the escape of non-native species. It is essential to recognise that not all changes related to climate change are negative, and in many cases, they can have positive effects. This chapter describes some of the impacts of climate change on the main aquaculture species and strategies that can promote aquaculture adaptation and mitigation of the negative effects while capitalising on the positive ones. For this purpose, two case studies are reviewed. One example shows how the effect of climate change on profitability can be analysed and the other demonstrates a participatory process in Chile to promote adaptability in coastal communities through diversifying into oyster farming.
