ISA (Infectious Salmon Anemia)

Infectious Salmon Anemia (ISA) is a serious disease affecting farmed Atlantic salmon caused by the Infectious Salmon Anemia Virus (ISAV). The virus attacks the fish's blood vessels, leading to anemia, rapid breathing, and often death. It spreads quickly among fish farms, impacting fish health and industry economics. Symptoms include lethargy, pale gills, and swelling. The disease is managed through strict biosecurity measures, regular testing, and culling affected stocks. ISA does not pose a risk to humans, but controlling its spread is crucial to safeguard salmon populations and the aquaculture industry.
