Climate Risks Projected to Bring Steep Falls in Fish Biomass Around the World’s Ocean

Scientists are warning that exploitable fish biomass faces climate risks across nearly all regions of the world’s ocean, including top producer countries and those with a high reliance on aquatic foods, under a high-emissions scenario.

Global projections of the potential fish biomass production show declines of more than 10% by mid-century for many regions of the world, particularly under the high-emissions scenario, according to the report released this week by the Food and Agriculture Organisation of the United Nations (FAO).

The report was produced by the Fisheries and Marine Ecosystem Model Intercomparison Project (FishMIP) program led by the University of Tasmania’s Institute for Marine and Antarctic Studies (IMAS).
