Abstract: The bactericidal and virucidal effects of hypochlorite produced by batch electrolytic system were examined for fish pathogens. Sodium chloride solutions, ranging from 0.5 to 3%, were electrolyzed and the concentration of chlorine produced was measured. Almost same concentration of chlorine was produced when 1.0% or more NaCl solution and seawater were electrolyzed. Fish pathogenic bacteria or virus was added to electrolyzed water and exposed to hypochlorite. More than 99% cells of Vibrio anguillarum, causative agent of fish vibriosis, were killed when the bacteria were exposed to 0.21 mg/l hypochlorite for 1 min. Yellowtail ascites virus (YAV) and hirame rhabdovirus (HIRRV), the causative agents of viral ascites disease and rhabdovirus disease of marine fish, were inactivated more than 99% after treatment with 0.42 mg/l hypochlorite for 1 min. The number of viable bacteria in the hatchery supply-seawater was reduced more than 99% when the water was treated with hypochlorite of 0.54 mg/l for 1 min. And more than 99% cells of viable bacteria in the waste-seawater were killed when the water was treated with hypochlorite of 0.64 mg/l for 5 min. The batch system developed in this study revealed remarkable bactericidal and virucidal effects, which were very similar to those in continuous flow-water system.
