Drift nets or gill nets are large nets for capturing fish. They hang vertically in the water column by weights at the bottom and are allowed to drift with the tide. Because drift netting can capture a large quantity of fish at the same time, it is a method that is commonly used to catch tuna, swordfish and salmon. Gill netting is so effective that their use is closely monitored and regulated by fisheries management and enforcement agencies. Fish can be caught in several ways from tangled in the net to held by the mesh slipping behind the opercula of the fish. During a trial driftnet fishery in Canadian waters in 1987, one vessel killed more than 200 sea mammals and 1000 birds. After this experiment, Canada refused to permit driftnet fishing. Without doubt, drift netting is not only detrimental to wildlife species but it is tremendously wasteful. About half of the catch either falls back into the water as the nets are being retrieved or is crushed to useless pulp by tons of fish and successfully retrieved fish are usually damaged and must be sold at a reduced price. However, there are countries and regions who have taken this into consideration and reduced this problem. For example, the European Union banned the use of drift nets for no longer than 2.5 km. Some organizations such as North Pacific Anadromous Fish Commission (NPAFC) that include Canada, the United States, the Russian Federation, Korea and Japan have already been monitoring four million square kilometres of the North Pacific Ocean. What ordinary people can do to reduce this negative impact is cause awareness to those who do not know about it so it can get adequate attention for effective protection for threatened sea lift. The broad public movement can fight for the survival of the species who are suffering from the greed of humans.
