Almost every krill fishing company operating in Antarctica has vowed to stop working in the region’s wildlife-rich waters.
The action will see operations abandoned in huge areas around the Antarctic Peninsula from 2020 – including ‘buffer zones’ around breeding colonies of penguins.
As a result there will be no krill entering the UK that has been caught in sensitive ecosystems.
The companies have also agreed to back a campaign supported by 1.7 million people globally pushing for the creation of a vast network of Antarctic protected zones – including a 1.8 million square km area in the Weddell Sea.
If successful the proposed Antarctic ocean sanctuary would be the largest wildlife reserve on the planet.
