A multifilament, three-layer gill net consists of three layers of mesh, and each layer contains multiple filaments. This design aims to increase the density and capture efficiency of the fishing net, making it suitable for different species and sizes of fish. The multifilament structure allows the net to better catch small target fish while maintaining sufficient strength and durability. This type of gillnet is widely used in commercial fishing, but it needs to be used with caution to ensure the sustainability of the fishery.
