In November 1991 the daily mortality rate increased from 0.01 to 0.06% in 2 netpen-reared Atlantic salmon cages at a fish farm located in coastal waters off British Columbia. Clinical signs and PM findings were consistent with those of a disease associated with a rickettsia-like organism in farmed Chilean Coho Salmon. This condition has not previously been reported from British Columbia..
