PROBLEM TO BE SOLVED: To solve the problem that a technique for positively utilizing electrolytic water useful for the health, growth and lives of cultured fishes has not been proposed, although a method for removing substances injurious to cultured fishes from fish-culturing water or a method for sterilizing the fish-culturing water has been proposed.SOLUTION: This cultured fish-activating apparatus is manufactured by integrating means for producing electrolytic water, and prevention means for preventing fishes from approaching electrodes or the like, with a filtration function.COPYRIGHT: (C)2008,JPO&INPIT【課題】養魚水から養魚に有害な物質を除去したり、殺菌したりする方法は提案されているが、電解水が養魚の健康、成長及び寿命に有益である事を積極的に利用する技術は提案されていない。【解決手段】本発明は、電解水を生成する手段と魚が充電部である電解極などに近づく事を防ぐ防御手段を濾過機能と併せて一体構造としたものである。【選択図】図1
