Evaluating climate change risks to Patagonian and Antarctic toothfish

This paper provides an overview of a new research project to evaluate climate change risks to toothfish in subareas 48.3 and 48.4. The CCAMLR Convention Area is one of the world’s most rapidly changing oceanic regions, with major impacts both observed and expected on marine ecosystems due to climate change and consequences for the conservation and management of marine living resources. Focusing on Patagonian and Antarctic toothfish (Dissostichus eleginoides and D. mawsoni) this project will synthesise and review relevant environmental, biological and fishery information, undertake analyses for an ecological risk assessment of climate change effects on the species, and use this to provide information for decision-makers. Project findings will be submitted to CCAMLR meetings during 2024-25
