The seasonality of proliferative kidney disease (PKD) and the effects of water temperature on the development of the disease in naturally-infected fingerling rainbow trout, Salmo gairdneri, were investigated. Fingerling rainbow trout became infected from May to October, but those infected in October did not develop clinical disease. In naturally-infected fish subsequently held under laboratory conditions, clinical PKD occurred at 12-18°C, but not at 9°C. The disease progressed more rapidly and was more severe as temperatures increased. On re-exposure to infection, rainbow trout previously held at 9°C developed clinical PKD, whereas in those previously held at 12°C it did not develop. Possible implications of these findings for the control of PKD are discussed.
