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

摘要

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.
