Greenpeace activists create ‘boulder barrier’ in North Sea to deter industrial fishing

Action taken to prevent bottom trawling in the marine protected area and conserve porpoise populations

Greenpeace activists have dropped boulders in the North Sea to snag the dragnets of industrial trawlers fishing in a marine protected area.

Activists onboard the Greenpeace ship Arctic Sunrise dropped the giant stones to form an underwater barrier around the Southern North Sea marine protected area (MPA) - the UK's most bottom-trawled MPA.
