Abstract: Cidal effect of ultraviolet irradiation on 10 strains of fish pathogenic aquatic fungi and 6 specises of bacteria including fish pathogens were examined. The results obtained are summarized as follows: 1) The punched agar medium disk covered with fungus hyphae was employed for the measurement of susceptibility to ultraviolet irradiation of aquatic fungi. The hyphae of 10 strains of aquatic fungi, i.e. Saprolegnia parasitica IFO 8978 etc. show relatively lower susceptibility to ultraviolet irradiation compared with the bacteria. The minimal fungicidal dosage of ultraviolet irradiation, inhibition of growth of hyphae, was 154~252×10^3μW・sec/cm^2. 2) This dosage was about 50 times higher than the minimal bactericidal dosage of ultraviolet irradiation for destruction, at least 99.9% of viable bacterial cells.
供試した10株の魚病関連ミズカビのU.V.感受性は意外に低く,菌糸の殺菌に要するU.V.照射量は154~252×10^3μW·sec/cm2と対照に用いた細菌の殺菌に要する最小U.V.照射量4~5x10^3μW·sec/cm2の約50倍が必要であった。以上の結果から養魚用水中のミズカビの完全殺菌にはかなり強力なU.V.照射装置が必要と考えられる。
