The ancients used coarse cloth and hemp as raw materials to make fishing nets by bundling. Although this fishing net is perishable and has poor toughness, its fishing efficiency has been greatly improved. With the development of fishery, the objects of fishing and hunting are not only fish, but also the fishing tools are advancing with the times. Modern fishing nets are mainly processed with polyethylene, nylon and other raw materials. It has a longer lifespan and higher fishing efficiency, and is classified by different ways of use. For example, cast nets used in traditional fishing (hand nets, hand cast nets), trawl nets powered by boats, gill nets (triple nets, seine nets) with different meshes to hang gills and trap fish, etc. These nets are woven with meshes of different sizes and wires of different materials for different fishing objects. At the same time, as the development of fishing nets, various fishing tools are also produced, such as fishing cages and four-corner nets, which are commonly used fishing tools.
