MAIN POINTS

Massive Fish Study
“...study looked at historical abundance data for 124 species in 38 regions, which represents roughly one-third of the reported global catch. The researchers compared this data to records of ocean temperature and found that 8 percent of populations were significantly negatively impacted by warming, while 4 percent saw positive impacts. Overall, though, the losses outweigh the gains.”

Regional Influences Biggest
“Region had the greatest influence on how fish responded to rising temperatures, according to the study. Species in the same region tended to respond in similar ways. Fishes in the same families also showed similarities in how they responded to changes.”

Losers & Winners
“...availability of fish for food has changed from 1930 to 2010, the researchers saw the greatest losses in productivity in the Sea of Japan, North Sea, Iberian Coastal, Kuroshio Current and Celtic-Biscay Shelf ecoregions. On the other hand, the greatest gains occurred in the Labrador-Newfoundland region, Baltic Sea, Indian Ocean and Northeastern United States.”

East Asia Losses 15-35%
“...East Asia has seen some of the largest warming-driven declines, with 15 to 35 percent reductions in fisheries productivity. "This means 15 to 35 percent less fish available for food and employment in a region with some of the fastest growing human populations in the world,”

Not Just Temp Stress
“Ocean acidification, falling oxygen levels and habitat loss will also impact marine life.”
