[PROBLEMS] To prevent microorganisms, barnacles, etc., which grow by attaching to a fishnet, from attaching to the fishnet and growing. For example, a fishing net for the purpose of tuna aquaculture is produced using polyethylene resin fibers made by mixing carbon black or fine copper powder into polyethylene resin and making it conductive. On this aquaculture net, a weak direct current or an alternating current is applied to the surface of the aquaculture net where tuna is cultivated to electrolyze seawater to produce highly toxic calcium hypochlorite, Microbes, barnacles, pearl shells, etc. that grow on the surface of the gill net, which is the aquaculture net that cultivates tuna by generating on the surface of the aquaculture net that performs tuna farming, It is a solution means that it is possible to prevent growth and growth due to adhesion of seaweed and seaweed.
