Relationship of River Pollution to Bacterial Infection in Salmon (Salmo salar) and Suckers (Catostomus commersoni)

Abstract

During the summers of 1967 and 1968, the bacterium, Aeromonas liquefaciens, was involved in disease of Atlantic salmon (Salmo salar) and suckers (Catostomus commersoni) in the Miramichi River, New Brunswick. A surge of copper and zinc pollution in late June 1967, and high river temperatures enhanced production of an epizootic. The epizootic recurred during the summer of 1968.
