Under the highest-emission scenario, many countries would see substantial reductions in seafood available from exclusive economic zones by 2050. [1]Fisheries are affected by climate change in many ways: marine aquatic ecosystems are being affected by rising ocean temperatures, [2] ocean acidification [3] and ocean deoxygenation, while freshwater ecosystems are being impacted by changes in ...
