The disinfectant efficacy of chemical treatments on parthenogenetic eggs of the rotifer was investigated. Treatments using several types of alcohol ranging from 30 to 70% concentration, several phenolic, compounds at 1 to 5%, and 0.1 % of benzalconium chloride were effective in terms of disinfection, but hatching were not observed. No effects of disinfectant were observed by treatment with formalin and sodium hypochlorite under several conditions which would enable hatching of the eggs. Glutaraldehyde treatment at concentrations ranging from 1,000 to 2,000 mg/L for 30 min effectively disinfected the rotifer eggs and did not reduce hatching rate of parthenogenetic eggs.
