By definition, Aeromonas salmonicida is found in fish but never in surface water. However, this does not explain the reason for explosive out‐breaks of furunculosis among populations of salmonid fish which have never been exposed to the disease. Evidence is presented, from laboratory‐based experiments, which show that A. salmonicida survives in freshwater, beyond the period necessary for plate counts to reach zero. These cells may subsequently be re‐activated by the addition of nutrient. It may be assumed, therefore, that A. salmonicida survives outside of fish, by entering a dormant phase.
