A variety of seafood certification schemes have developed over the past decade, all claiming that the fish that they certify have been sustainably caught or farmed and that they are the best option for consumers to purchase. Greenpeace is of the opinion that no fully credible certification programme for sustainable wild-caught or farmed seafood currently exists. So far, the challenges facing our oceans are far from being tackled and the fundamental principles of precaution and ecosystem approach are not yet incorporated into fisheries management.
