Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a water mold pest control method and fish egg sterilization method by using chlorine dioxide having toxicity lower than that of bronopol, and having high safety, and provide a water mold pest control agent and fish egg sterilization agent containing chlorine dioxide as an effective principle.SOLUTION: The present invention is configured so that, chlorite in a density range of 2.5 ppm or higher and 200 ppm or lower in conversion of effective chlorine dioxide, is added to cultivation water whose pH is 5.5 or higher and 8.5 or lower, and then making the cultivation water and the chlorite react for 60 minutes or longer, thereby pest control of water mold is achieved. At this time, organic acid or inorganic acid is not added to the cultivation water.SELECTED DRAWING: None 【課題】ブロノポールよりも毒性が低く、安全性の高い二酸化塩素を使用して、養殖用水中の水カビ防除方法及び魚類卵殺菌方法を提供すること。二酸化塩素を有効成分として含有する養殖用水用の水カビ防除剤及び魚類卵用殺菌剤を提供すること。【解決手段】本発明では、pHが5.5以上8.5以下である養殖用水に、亜塩素酸塩を有効二酸化塩素換算で2.5ppm以上200ppm以下の濃度範囲で添加し、60分間以上反応させることにより水カビを防除する。このとき、有機酸又は無機酸は養殖用水に添加しない。【選択図】なし
