Drift net
From Wikipedia, the free encyclopedia
A drift net is a type of fishing net used in oceans. They can range from 75 feet to miles in length. The term "drift" comes from the way these nets are used. They have been criticized by environmentalists.
One of the impacts of drift nets (often 17 km in length) is the bycatch. Dolphins, endangered sea turtles, sharks, and other larger sea creatures get entangled in the nets. But juvenile fish and non-target species are also caught and are later thrown overboard, most of them dead or dying.
Greenpeace is an organisation which works against drift nets. Information from their website can be found here.
