What are fishing nets made of?

The nets used for fishery production are trawl nets, purse seines, cast nets, set nets and net boxes. Trawls and purse seines are heavy nets used in marine fisheries. Mesh size of 2.5 ~ 5 cm, rope diameter of 2 mm or so, the net weight of several tons or even dozens of tons, usually with a pair of trawlers pulling the head to chase the fish or by the lights of the boat to lure the fish concentrated and surrounded. Spreading net for river and lake fishing with light net gear. Mesh size of 1 ~ 3 cm, net rope diameter of 0.8 mm or so, net weight several kilograms. Set net and net box for lakes and reservoirs or bays for artificial aquaculture fixed nets. Size and specification according to the fish and different, the fish enclosed in a certain amount of water breeding does not make the escape.

As the name implies, fishing nets are nets used for fishing, and ancient people used coarse cloth and hemp as raw materials to make fish nets by bundling and rolling. Although this kind of fishing net is perishable and poor toughness, but its fishing efficiency has been greatly improved. With the development of the fishing industry, the object of fishing and hunting is not only fish, fishing tools have also evolved with the times.

Fishing nets. Fishing special tools structural materials. 99% or more processed with synthetic fibers. Mainly nylon 6 or modified nylon monofilament, compound filament or compound monofilament, but also can use polyethylene, polyester, polyvinyl chloride and other fibers. Fishing nets serve many purposes.

Ancient people used coarse cloth plus hemp as raw material to make fishing nets by bundling and rolling. Although this kind of fishing net is perishable and has poor toughness, its fishing efficiency has been greatly improved. With the development of fisheries, the object of fishing and hunting is not only fish, fishing tools have also advanced with the times. Modern fishing nets are mainly processed with polyethylene, nylon and other raw materials. They have a longer service life and higher fishing efficiency, and are categorized by different ways of use. For example, cast nets (hand nets, hand cast nets) are traditionally used for fishing, trawls are powered by boats, and drift nets (triple nets, purse seines) are used to trap fish with different mesh gills. These nets are made with different sizes of mesh and different materials of netting for different fishing targets. At the same time, as the development of fishing nets, a variety of fishing gear also came into being, such as fishing cages, quadrangular nets, etc., which are commonly used as fishing tools.
