• Flatfishes (order Pleuonectiformes) are important to fisheries and contribute substantially to seafood production and people's livelihood. However, the sustainability of flatfish fisheries is being challenged by climate change, in addition to other non-climatic human stressors. There is an urgent need to expand our understanding of the vulnerability and risk of impacts of flatfishes and their fisheries to climate change, and identify possible options to moderate such impacts. In this paper, firstly, we explain the importance of ocean temperature and thermal characteristics of flatfishes in determining their biogeography. Secondly, we discuss the biological vulnerability of flatfishes in the world to climate change as indicated by quantitative indices estimated from a fuzzy logic algorithm. Thirdly, by presenting projections of future distribution and potential catches of exploited flatfishes from computer simulation models, we highlight specific regions and species that are expected to be most impacted by climate change. Finally, we discuss potential human interventions that could help reduce such impacts, including the potential for mariculture. This paper underscores the need for immediate actions to integrate climate change into flatfish conservation and fisheries management measures. •Species with the highest climate risk include spottail spiny turbot, west coast sole, spiny turbot and yellowtail flounder.•67% of the flatfish stocks in north Atlantic and Pacific Ocean were projected to shift poleward at average rate of 39.1 km decade-1.•Maximum catch potential of flatfish was projected to decrease by 9.3% and 17.3% by 2080 under RCP 2.6 and RCP 8.5.•Areas with the highest risk of climate impacts for flatfish include the north Atlantic and Indo-Pacific regions.•Climate change impacts flatfish aquaculture through changing environmental suitability for farming, diseases, and supply of fishmeal and fishoil.
