The chief objectives of the project were: (a) To determine the effect of water temperature upon the mortality resulting from the more important infectious diseases of salmonid fish; and (b) To obtain additional information concerning the effect of water temperature on antibody formation and the immune response in salmonid fish. The diseases which have been studied have included those caused by Flexibacter columnaris, Aeromonas salmonicida, Aeromonas liquefaciens, and the organism causing bacterial kidney disease (Corynebacterium sp.). In an earlier report similar studies of ceratomyxosis and infectious hematopoietic necrosis were described. Fish species in the experiments reported here were juvenile coho (Oncorhynchus kisutch) and chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (Salmo gairdneri).
