In an effort to preserve fishing stocks, the European Union uses a quota system to regulate the amount of fish that can be taken out of the North Sea. This involves defining the tonnage of the various types of North Sea fish that each EU member country can take. As soon as the catch is landed - but not before  fishermen can be fined for landing more fish at their port than their quota permits. Each year fishermen dump thousands of tonnes of fish back into the sea either because they have reached their quota and dont want to be fined or because the fish are too small to be caught legally. Some environmental groups feel that existing approaches are not working since these fish are already dead and throwing them back serves no real purpose. They believe that other steps need to be taken to conserve North Sea fishing stocks and avoid depletion.
