Climate change to wreak havoc on fisheries

New research on marine ecosystems’ likely response to climate change pressures, presented at the AAAS Annual Meeting this month, predicts significant changes in commercially-important fish species’ distribution in the world’s oceans.

Some of the findings include:

  • There will be a large-scale re-distribution of species, with most moving towards the Pole
  • Developing countries in the tropics will suffer the biggest loss in catch
  • Nordic countries such as Norway will gain with increased catch
  • Some species will face a high risk of extinction, including Striped Rock Cod in the Antarctic and St Paul Rock Lobster in the Southern Ocean
  • The invasion and local extinction of species may disrupt marine ecosystems and biodiversity
