Results – Wild Salmon

Wild salmon (chum, sockeye, steelhead, coho, spring) were sampled in watersheds throughout British Columbia in the fall of 2011 and spring of 2012. So far, we have detected ISAv and IHNv in our wild samples:

  • ISA virus – coho, chum and chinook spawners, Harrison Mills, Fraser; sockeye fry, Rivers Inlet; chum spawner, Vedder River
  • IHN virus – chum spawner, Sharp Creek, Clayoquot; sockeye spawner, Kennedy River; chinook spawner, Muriel Creek; chum spawner, Englishman River; sockeye spawner, Northern Sprout Lake River; sockeye spawner, Sprout Lake
