Dangers of Overfishing
Most countries recognized that driftnets harm too many marine species to remain an acceptable form of fishing. The United Nations banned them on the high seas in 1993, and the European Union followed suit in 2002. In 2003, ICCAT prohibited the use of driftnets to catch tuna and swordfish.
Driftnets sound relatively harmless as a fishing method. But as any marine biologist will tell you, this gear threatens ocean wildlife.
Held on the sea’s surface or just below with floating devices, driftnets can be miles long. Depending on the size of the mesh, they can entangle anything that happens to swim nearby, including sea turtles, whales, swordfish, and tuna.
