Vibrio anguillarum and V. ordalii Disinfection for Aquaculture Facilities

One of the major limitations to intensive aquaculture is disease. Diseases spread rapidly in an aquatic environment and pose a major threat to development and utilization of all species in aquaculture. Bacteria of the genus Vibrio play a major role in the diseases of cultured species of marine fish. The goal of reducing the incidence of disease in a population is either to eliminate potential pathogens or to increase the resistance of the host. To reach that goal, a disinfection assay to test the effectiveness of nine common aquaculture chemical compounds was evaluated against two marine bacterial pathogens (Vibrio anguillarum and V. ordalii). Both bacterial species were susceptible to a variety of common disinfecting compounds including Chloramine-T®, chlorine, ethanol, iodine, Lysol®, Roccal®, and Virkon-S®.
