STERILIZATION METHOD AND APPARATUS FOR FEED CREATURE

PROBLEM TO BE SOLVED: To provide a sterilization method and a sterilization apparatus each sterilizing feed creatures cultured under the natural environment without synthetic antibacterial drug or chemical agent just before giving to seeds of fish and shellfish. SOLUTION: This sterilization apparatus 1 is based on the sterilization method for the feed creatures comprising irradiating ultraviolet rays toward the water surface of an aqueous solution in which the feed creatures float so as to sterilize harmful bacteria which the feed creatures floating in the aqueous solution hold. The sterilization apparatus 1 is composed of a storing container 12 storing an aqueous solution in which the feed creatures float, an ultraviolet ray irradiating part 14 irradiating ultraviolet rays toward the water surface 122 of the aqueous solution 121 which the storing container 12 stores, an apparatus main body 11 holding the storing container 12 and the ultraviolet ray irradiating part 14 in prescribed positional relationship and a control part 16 operating and stopping the ultraviolet ray irradiating part 14.
