This report provides a preliminary assessment of the state of knowledge of the implications of climate change for fisheries and aquaculture in Australia. This review identifies that there are likely to be significant climate change impacts on the biological, economic, and social aspects of Australian fisheries and finds that there is little consolidated knowledge of the potential impacts of climate change. Both positive and negative impacts are expected, and impacts will vary according to changes in the regional environment: south-east fisheries are most likely to be affected by changes in water temperature, northern fisheries by changes in precipitation, and western fisheries by changes in the Leeuwin Current.
