Drift netting is a fishing technique where nets, called drift nets, hang vertically in the water column without being anchored to the bottom. The nets are kept vertical in the water by floats attached to a rope along the top of the net and weights attached to another rope along the bottom of the net. [ 1 ]
Net haulers are usually used to set and haul driftnets, with a drifter capstan on the forepart of the vessel. In developing countries most nets are hauled by hand. The mesh size of the gillnets is very effective at selecting or regulating the size of fish caught. The drift net has a low fuel/fish energy consumption compared to other fishing gear.

A surrounding net is deployed by a fishing boat that starts sailing in a circle. This allows for the net to come all the way around 360 degrees to completely surround the fish. This makes it so that there is no escape for the fish. There are floating buoys on the top of the net and weights on the bottom of the net to make sure that it forms a wall.
When the net is full, a retrieval clamp, which works like a wringer on a mop, closes the net around the fish. The net is then retrieved by pulling on this handline. The net is lifted into a bucket and the clamp is released, dumping the caught fish into the bucket. [2] Cast nets work best in water no deeper than their radius.
In British waters, drifters were a type of fishing vessel with hauled drift nets. This was adapted by the Royal Navy for anti-submarine defence in approaches to harbours and ports by laying drift nets and snagging enemy submarines. [1] In January 1917 the Royal Navy ordered 100 drifters from Canadian shipyards as part of a building programme in ...
The Lydia Eva is the last surviving steam drifter of the herring fishing fleet based in Great Yarmouth. A drifter is a type of fishing boat. They were designed to catch herring in a long drift net. Herring fishing using drifters has a long history in the Netherlands and in many British fishing ports, particularly in East Scottish ports.
