Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a technique for preventing adhesion and growth of microorganisms, barnacles, pearl shells, Undaria pinnatifida and the like to the surface of a fishing tool such as a crawl net, a fixed shore net or a rope and removing the same, and a method for cultivating tuna using a crawl net.SOLUTION: A fishing tool such as a crawl net, a fixed shore net or a rope is produced by mixing chlorine, hypochlorous acid, calcium hypochlorite, synthetic pyrethroid, an organic phosphorus-based insecticide and the like into the inside of a resin. In addition, the culture of tuna that can not be performed without using a crawl net whose structure is circular with at least ≥20 m diameter is performed by using the crawl net whose diameter is ≤20 m, e.g., ≤10 m and whose shape is other than the circular shape, e.g., a square or a rectangular shape.
