Shrimp trawling and shrimp processing onboard the fishing vessel Sunna Tallinn. Greenpeace has been documenting and protesting the high seas bottom trawl fleets in the NW Atlantic. Greenpeace is calling on governments to put in place a UN moratorium on highseas bottom trawling because it is an unsustainable fishing technique that has destructive impacts on the marine ecosystems and poses serious threats to deep sea fish species. The Northwest Atlantic Fisheries Organisation (NAFO) has been in existence since 1979 to manage and conserve the fishery resources of the Northwest Atlantic. Despite its adoption of a wide range of conservation and management measures and a well developed institutional structure, NAFO has been unable to achieve its mandate and as of 2005, ten stocks under NAFO?s competence are currently under moratoria.
