In four experiments with fry and fingerling salmonids during 3 years, rainbow trout (Salmo gairdneri) were most susceptible to whirling disease (Myxosoma cerebralis) followed, in decreasing order of susceptibility, by sockeye salmon (Oncorhynchus nerka), brook trout (Salvelinus fontinalis), chinook salmon (Oncorhynchus tshawytscha), brown trout (Salmo trutta), and coho salmon (Oncorhynchus kisutch). Lake trout (Salvelinus namaycush) were completely refractory. Absence of infection was determined by absence of spores and signs in exposed young fish. Refractory or least susceptible species of salmonids should be reared in enzootic whirling disease areas.
