Information about Fishing Net

Fishing net or fishnet is a type of net that is use to enclose fish. All 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 in certain areas.

A landing net


A hand net, held open by a hoop and possibly on the end of a long stiff handle, has been known since antiquity and may be used for sweeping up fish near the water surface like muskellunge and northern pike. Such a net used by an angler to aid in landing a captured fish is known as a landing net.[1] In England, hand netting is the only legal way of catching eels and has been practiced for thousands of years on the River Parrett and River Severn.

A Cast net is small round net with weights around which is thrown by the fisher. Sizes vary up to about 4 m 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]

Coracle-fishing is performed by two men, each seated in his coracle and with one hand holding the net while, with the other, he plies his paddle. 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 then secured.

The Chinese fishing nets (Cheena vala) found at Kochi in India are an example of shore operated lift nets.[3] because such nets are horizontally held by a large fixed structure and periodically lowered into the water. Huge mechanical contrivances hold out horizontal nets of 20 m or more across. The nets are dipped into the water and raised again, but otherwise cannot be moved.

Drift net is a type of fishing net used in oceans, coastal seas and freshwater lakes. It is commonly used by many countries in the coastal waters.[4]

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

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.

Stake net is a form of net for catching salmon, consisting 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.

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.

Trawl is a large net, conical in shape, towed along the sea bottom. Trawling is a method of fishing that involves actively pulling a fishing net through the water behind one or more boats.

Mythology

The only historical claimant to the invention of the fishing net is the Norse giant/god Loki. (His invention, however, was inspired by the sea giantess Ran, who used her own net to trap lost sailors.).
