Ocean-Farmed Seafood at Risk from Climate Change, Says Study

A new study from the University of British Columbia warns that the supply of ocean-farmed seafood could drop 16% by 2090 if no action is taken to mitigate climate change. Researchers say that if we continue to burn fossil fuels at our current rate, the amount of seafood such as fish or mussels able to be farmed sustainably will increase globally by only 8% by 2050, and decline by 16% by 2090. By comparison, in a low-emissions scenario where the action is taken to mitigate climate change, mariculture is projected to grow by about 17% by the mid-21st century and by about 33% by the end of the century. The effects of climate on mariculture include loss of area where fish farming is viable and shortages of fish-oil and fish-meal-based feeds.
