Driftnets are large floating nets, which may be employed in the open ocean or along the coast, often stretching for many miles. They are designed to trap and entangle large fish such as tuna and swordfish. The largest driftnets used were more than 50 kilometers (30 miles) in length, extending to a depth of 30 meters (one hundred feet) from the surface.
