Infectious salmon anemia virus

Infectious Salmon Anemia Virus (ISAV) is an infectious viral disease of Atlantic Salmon. This highly contagious disease can be insidious, with an initially low mortality rate; however, the cumulative mortality can sometimes exceed 90% if the disease remains unchecked. The virus can be transmitted through water, but the highest risk factors for spread of disease are movement of live fish, discharge of untreated blood and contact with infected vehicles and equipment.
