PREVENTING FUNGUS OF BACTERIA, MICROORGANISM, ACORN BARNACLE, PEARL OYSTER, WAKAME SEAWEED, ETC. FROM ADHERING IN FISHING NET, FISHING GEAR, SHIP'S BOTTOM, BUOY, BATHROOM OR BATHHOUSE, AND METHOD FOR PREVENTING ADHESION THEREOF
PROBLEM TO BE SOLVED: To provide a method for preventing acorn barnacles and the like from adhering to a crawl net where yellowtail, sea bream, tunas, etc. are cultivated, and a ship's hull.SOLUTION: A crawl net is made by kneading titanium oxide, a chlorine compound, or an agricultural chemical such as a pyrethroid-based agricultural chemical and an organophosphorus-based agricultural chemical into the fiber made of polyethylene resin, etc. Also, by forming a coated film 37 of electrically conductive urethane on a bottom of a ship's hull 19 and 31 and causing an electric current to flow through it, sea water is electrolyzed to generate calcium hypochlorite so that adhesion of acorn barnacles or the like is prevented.【課題】ハマチ、タイ、及びマグロなどを養殖する生け簀網や船体にフジツボ等が付着しない様にする方法を提供する。【解決手段】ポリエチレン樹脂等で作った繊維に酸化チタン、塩素系化合物、或いはピレスロイド系又は有機リン系等の農薬を練り込んで生け簀網を作る。また、船体１９、３１の船底に導電性のウレタンにより塗膜３７を形成し、電流を流すことにより海水を電気分解して次亜塩素酸カルシウムを発生させ、フジツボ等の付着を防止する。【選択図】図４６
