Fishing net

A fishing net or fishnet is a net that is used for fishing. Fishing nets are meshes usually formed by knotting a relatively thin thread. Modern nets are usually made of artificial polyamides like nylon, although nets of organic polyamides such as wool or silk thread were common until recently and are still used.
Hand net


Main article: Hand net

Hand nets are held open by a hoop and are possibly on the end of a long stiff handle. They have been known since antiquity and may be used for sweeping up fish near the water surface like muskellunge and northern pike. When such a net is used by an angler to help land a fish it is known as a landing net.[1] In England, hand netting is the only legal way of catching eels and has been practised for thousands of years on the River Parrett and River Severn.

[edit] Cast net

Main article: Cast net

Cast nets are small round nets with weights on the edges which is thrown by the fisher. Sizes vary up to about four metres in diameter. The net is thrown by hand in such a manner that it spreads out on the water and sinks. Fish are caught as the net is hauled back in.[2]

[edit] Coracle fishing

Coracle fishing is performed by two men, each seated in a coracle, plying his paddle with one hand and holding a shared net with the other. When a fish is caught, each hauls up his end of the net until the two coracles are brought to touch and the fish is secured.

[edit] Chinese nets

Main article: Chinese fishing nets (of Kochi)

The Chinese fishing nets (Cheena vala) are used at Kochi in India. They are an example of shore operated lift nets[3] because they are held horizontally by a large fixed structure and periodically lowered into the water. Huge mechanical contrivances hold out horizontal nets with diameters of twenty metres or more. The nets are dipped into the water and raised again, but otherwise cannot be moved.

[edit] Gillnet

The gillnet catches fish which try to pass through it by snagging on the gill covers. Thus trapped, the fish can neither advance through the net nor retreat.

[edit] Drift net

Main article: Drift net

The drift net is a net that is not anchored. It is usually a gillnet, and is commonly used in the coastal waters of many countries.[4]. Its use on the high seas is prohibited, but still occurs.

[edit] Ghost net

Ghost nets are nets that have been lost at sea. They may continue to be a menace to marine life for many years.

[edit] Stake net

A stake net is a form of net for catching salmon. It consists of a sheet of network stretched on stakes fixed into the ground, generally in rivers or where the sea ebbs and flows, for entangling and catching the fish.

[edit] Fyke net

Fyke nets are bag-shaped nets which are held open by hoops. These can be linked together in long chains, and are used to catch eels in rivers. If fyke nets are equipped with wings and leaders, they can also be used in sheltered places in lakes where there is plenty plant life. Hundreds of these nets can be connected into systems where it is not practical to build large traps.[5]

[edit] Trammel

A trammel is a fishing net set vertically in the water with three layers. The inner layer is of a finer mesh than the outer layers.

[edit] Seine

Main article: Seine fishing

A seine is a large fishing net that may be arranged in a number of different ways. In purse seine fishing the net hangs vertically in the water by attaching weights along the bottom edge and floats along the top. A simple and commonly used fishing technique is beach seining, where the seine net is operated from the shore. Danish seine is a method which has some similarities with trawling.

[edit] Trawl

Main article: Trawling

A trawl is a large net, conical in shape, designed to be towed in the sea or along the sea bottom. The trawl is pulled through the water by one or more boats, called trawlers. The activity of pulling the trawl through the water is called trawling.
