Abstract

Since 1982, anemias occurring in stocks of yearling coho (Oncorhvnchus kisutch) and chinook salmon (Oncorhynchus tshawytscha) have been associated with serious losses at hatcheries in the Pacific Northwest, USA. The anemia is often accompanied by infections with external fungus (e.g. Saprolegnia) or the bacterial pathogens Cytophaga psychrophila or Renibacterium salmoninarum (Holt and Rohovec 1984, Leek 1987). The losses associated with the anemia are thought to be caused by these secondary infections.
