Life of Fisherman - How To Catch Fish Using Net
12Different Types of Netting Techniques Used
by Firsherman to Catch Fish:
Cast nets - are round nets with small weights distributed around the edge. They are also called throw nets. The net is caste or 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.[12] This simple device has been in use, with various modifications, for thousands of years.Drift nets - are nets which are not anchored. They are usually gillnets, and are commonly used in the coastal waters of many countries. Their use on the high seas is prohibited, but still occurs.Ghost nets - are nets that have been lost at sea. They can be a menace to marine life for many years.Gillnets - catch fish which try to pass through by snagging on the gill covers. Trapped, the fish can neither advance through the net nor retreat.Haaf nets - mainly used in the Solway Firth forming part of the border between England and Scotland. Brought to Great Britain by the Vikings a thousand years ago, the technique involves the fisherman wading out to deep waters with a large rectangular net and waiting for salmon to swim into it. The fish is then scooped up by the raising of the net.Hand nets - are small nets held open by a hoop. They have been used since antiquity. They are also called scoop nets, and are used for scooping up fish near the surface of the water. They may or may not have a handle–if they have a long handle they are called dip nets. When used by anglers to help land fish they are called landing nets.[13] Because hand netting is not destructive to fish, hand nets are used for tag and release, or capturing aquarium fish.Lift nets - are a method of fishing using nets that are submerged to a certain depth and then lifted out of the water vertically. The nets can be flat or shaped like a bag, a rectangle, a pyramid, or a cone. Lift nets can be hand-operated, boat-operated, or shore-operated. They typically use bait or a light-source as a fish-attractor.[14]Cheena vala - are shore operated lift nets from India.[15] 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. Its name means "Chinese fishing net", though it originates from Southeast Asia.Salambaw - a type of traditional raft or barge-operated large lift nets from the Philippines. It utilizes a tall upright pole or a tower structure (timba) around 15 to 20 m (49 to 66 ft) in height. At the top of the pole are two large curving spars crossed with each other. A large square net is attached to the ends of these spars. The pole acts as a crane, it can be tilted to submerge the net using a weighted lever mechanism. The operator either pushes or pulls the lever, or climbs on it to bring it down with their body weight, thus raising the pole. A variation of the salambaw operated from large outrigger boats is known as basnigan.[16]Seine nets - are large fishing nets that can be arranged in different ways. In purse seining fishing the net hangs vertically in the water by attaching weights along the bottom edge and floats along the top. Danish seining is a method which has some similarities with trawling. A simple and commonly used fishing technique is beach seining, where the seine net is operated from the shore.Surrounding nets -Tangle nets - also known as tooth nets, are similar to gillnets except they have a smaller mesh size designed to catch fish by the teeth or upper jaw bone instead of by the gills.[17]Trawl nets - are large nets, 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.
