Experimental treatment by increasing temperature from 10°C to 16°C was carried out on juvenile coho salmon (Oncorhynchus kisutch) naturally infected with erythrocytic inclusion body syndrome (EIBS).
Cumulative mortality of control fish kept at 10°C throughout the experimental period of 40 days was 57%. In contrast, that of experimental fish kept at 16°C for the first 23 days and then at 10°C for 17 days was 10%. The longer the period at which the fish were kept at the higher temperature (16°C), the lower the mortality. Experimental challenge with EIBS to the survivors of the temperature-increasing treatment revealed an increase in the resistance to reinfection of EIBS.
