The suceptibility to R. salmoninarum was examined in chum salmon cultured in fresh water and sea-water, and in those transferred from fresh to sea-water. The most susceptible fish were chum salmon cultured in sea-water, death by R. salmoninarum was 100%. The chum salmon transferred to sea-water also exhibited high mortality (100% in 107 cell injected group and 96.6% in 106 cell injected group). The least mortality occurred in fish cultured in fresh water (100% in 107 cell injected group and 41.4% in 106 cell injected group). These results show that the sea-water environment increases the susceptibility of chum salmon to BKD.
