For commercial fishing, the use of a fishing net is very important. Fishing nets are responsible for the largest share of fish catches, and they are used in a vast variety of structures and designs, depending on the species of fish being targeted. Here we will see how some fishing nets work.
How Fishing Net Works
Gillnets And Entanglement Nets
How gillnets works are that a fish swims into the net and passes through only partly. As the fish makes an attempt to free itself from the net, the twine can entangle the fish and stop it from swimming elsewhere, such as at the;
- The fish tries to swim through one or additional meshes; if it cannot move, it becomes caught behind its gill covers as it tries to back out of the net.
- The fish is tight control within the internet around the body by one or additional meshes
- The fish is caught within the internet by some a part of its bodies, such as protruding fins or spines.
The gillnets perform on the principle that fish are reluctant to swim over a moving object within the water and instead try and swim before it. The fish concentrates at the bunt (end of the net which has been heavily reinforced), when the net is hauled onto the beach evenly, by hand, four-wheel drive vehicle or tractor, herding the fish into the net.
When the line is pulled, it effectively closes the bottom of the net, the fish are thus herded by the ropes and wing ends into the net. The watercraft travels round the faculty, setting the net, and the headline is then winched in so that both ends of the net are beside the vessel. The purse line is winched in from both ends, closing off the bottom of the net. Hauling continues till cyber web and fish are dragged onto the shore, with the fish are concentrated in the bag.

They produce a cloud of muddy water that hides the oncoming fishing net. It additionally makes a noise that attracts fish. The fish begin to swim before of cyber web mouth.
Because the trawl continues on the bed, fish begin to tire and slip into the net. Finally, the fish become exhausted and move, into the net and are caught. The speed that the trawl is towed at depends on the swimming speed of the species that is being targeted. It additionally depends on the gear that’s getting used. For many species, a speed of around four knots (7 km/h) is suitable.
The front a part of this net is set on the ocean bottom. You can either wait till a school swims into the net, or drive fish into it by making some form of commotion. Then the net is closed by lifting the front end that the fish cannot escape.
The long cylindrical netting bag creates an easy entry but makes exit troublesome. This net is then mounted on rigid rings or different rigid framework and stuck on the ocean bed by anchors, ballast or stakes it also has wings or leaders to assist guide the fish towards the threshold of the bag.
Throwing the cast net creates a driving force that causes the lead line to open the net to a flat form, the lead weights then sink the net. After the net has sunk, and the rail line is pulled, the lead line is forced to close, this will create a pouch in the net which holds the catch, trapping a school of fish. After pulling the net from the water, opening the leadline will cause the catch to fall out.
