The quality of the knot of nylon monofilament fishing nets has a significant impact on fishing efficiency, mainly because the quality of the knot directly affects the performance and efficiency of the fishing net. The following are some reasons why the quality of net knots affects fishing efficiency:

    Mesh size: The quality of the mesh directly affects the mesh size and uniformity of the fishing net. The size of the mesh determines the size of the target fish species to be caught, and a uniform mesh can ensure that the mesh is evenly distributed during the fishing process, without too large or too small mesh holes, improving the selectivity of fishing.

    Strength and durability: The quality of the net knot is closely related to the overall strength and durability of the fishing net. A good net structure can evenly distribute the tension of the fishing net, reduce local excessive stress, thereby improving the durability of the fishing net and preventing breakage during the fishing process.

    Tensile strength: A good net knot helps the fishing net resist tension. When fishing, the fishing net needs to withstand the tension of water flow, tides, and target fish, and a good net structure can effectively disperse these tensions, slow down the wear of the net structure, and improve the tensile strength of the fishing net.

    Resistance: Uneven or damaged knots can increase the hydrodynamic resistance of fishing nets and reduce fishing efficiency. A uniform and tight net structure can reduce resistance, making it easier for fishing nets to cross water bodies and improving fishing efficiency.

    Environmental protection: A good net structure helps prevent the production of residual waste or debris from fishing nets, reducing negative impacts on the marine environment. A good mesh design can also reduce the fishing of non target species by fishing nets, which helps maintain ecological balance.

    In summary, the quality of the net structure is directly related to the structural stability, durability, fishing efficiency, and environmental impact of fishing nets. Therefore, effective management and maintenance of the quality of fishing nets in their manufacturing and use are crucial for improving fishing efficiency and sustainable fisheries.
