Drift nets are nets 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 also juvenile fish and non-target species get caught and are later thrown over board most of them dead or dying.

Fishing nets include the stationary net, an early type; the driftnet, an oblong vertical net, buoyed on its upper edge; the seine, whose ends are brought together to enclose the fish; and the bag-shaped trawl net, dragged along sea bottom.
Hair nets include the gold or silver, wire or cord cauls worn in ancient Egypt, Greece, and Rome; reticulated caps and cauls popular in Europe especially in the 14th cent.; chenille or ribbon snoods of the 19th cent.; and the "invisible" net of human hair.
Nettings are used also for safety nets, for hammocks, and for hoisting loads.
