Science
  • Uses temperature-specific models and hindcasting across fish stocks to determine the degree to which warming has, and will, affect fish species
  • Finds that an overall reduction in yield has occurred over the past 80 years
  • Hindcasts indicate that the maximum sustainable yield of the evaluated populations decreased by 4.1% from 1930 to 2010, with five ecoregions experiencing losses of 15 to 35%
  • Finds that although some species are predicted to respond positively to warming waters, the majority will experience a negative impact on growth
