| Abstract: | The effect of ultraviolet disinfection (22-63×10^3μW・sec/cm^3) of water supply on hatching rate of salmon eggs, masu salmon (Oncorhynchus masou) and chum salmon (O. keta) were examined. The results obtained are summarized as follows: 1) Viable bacterial counts were decreased about 90% in ultraviolet treated water, but viable fungi counts did not decrease to the same degree as the bacterial counts. 2) The eying rate and hatching rate were about 20% higher in the ultraviolet treated hatching tray than the untreated control, the fungi infection rate of the egg decreased about 19%. 3) Utilization of disinfection of hatchery water supply by ultraviolet irradiation was expected to increase the eying rate and the hatching rate. |
