Gill net fishing is a common commercial fishing method in the ocean, fresh water and some estuaries. Gill net fishing is a very easy to manage and monitor fishing methods. Through the size of the fishing net and the thickness of the ply line, the object to be caught can be accurately controlled.
The net is named because of the way it is used. It's a trap for fish. The fish can swim in but can't pass through it with precisely set mesh. When they want to go back, the gills of the fish hang on the net. In order to effectively capture them.
Fishermen who first used the gill net used canoes and cedar fiber nets. They used stones to weight the bottom of the net and let it sink into the water. Wood was attached to the top of the net to let it hang vertically in the water. Fix the net between the two boats.
Today's fishermen use iron boats and nylon multifilament nets, nylon monofilament nets, polyethylene nets, polyethylene ropes to weave nets. Lead is used to weight the bottom of the nets and let them sink into the water. Plastic buoys are attached to the top of the nets to let the nets hang vertically in the water and fix the nets between the iron anchors.
