A three-layer gillnet is a commercial fishing net composed of three layers of mesh. This design is intended to increase the efficiency of the fishing net and increase the likelihood of a catch. Commercial fishing nets are generally used for large-scale fishing, and their structures and materials are selected to adapt to various marine environments and different types of target fish. Three-layer gillnets provide greater coverage during capture, helping to increase catch numbers. This type of net is widely used in fisheries, but it also needs to be used with caution to ensure the sustainability of the fishery.
