Abstract: The effects of ozonized seawater on bacterial population and survival of cultured Japanese flounder (Paralichthys olivaceus) and barfin flounder (Verasper moseri) were investigated. The number of viable bacteria was reduced in more than 99.9 % and Vibrio sp. could not be detected after seawater was treated with total residual oxidants (TROs) of 0.5 or 1.0 mg/ l, for 8.5 minutes. TROs showed toxicity for fish; barfin flounder died 16 and 2 hours at TROs of 0.1 and 0.5 mg/ l, respectively. However, Japanese flounder could be cultured in ozonized seawater after removed of the TROs by charcoal, showing similar survival rates as fish cultured in U. V.-treated or non-treated seawater. Therefore, ozonization of seawater seem an effective methods for disinfection of fish culture water.
海水のオゾン処理による飼育水の殺菌効果とヒラメ (Paralichthys olivaceus) とマツカワ (Verasper moseri) の生存率に及ぼす影響について検討した。飼育水を残留オキシダント (TROs) 濃度が0.5と1.0mg/lとなるように設定し, 8.5分間処理したところ海水中の生菌数は99.9%以上減少し, Vibrio属細菌が検出されなくなった。また, 飼育水槽中のTROs濃度を0.1と0.5mg/lに設定し, マツカワ稚魚を飼育したところ, それぞれ16時間後および2時間後に供試した全個体が死亡した。オゾン処理海水を活性炭槽に通し, 生成したTROsを除去した海水でヒラメを飼育した場合, 紫外線処理海水および無処理海水飼育群とほとんど差は認められなかった。以上の結果および既報の魚類病原細菌に対するオゾンの殺菌効果から推定して, オゾン処理は飼育水の魚類病原微生物の殺菌に有効な方法であると思われる。
