Infectious Salmon Anaemia: Impacts and Findings

Infectious Salmon Anaemia (ISA) is a disease affecting salmon, brown trout, and rainbow trout with symptoms like loss of appetite, abnormal swimming patterns, and bleeding. ISA has been found in Chile, Norway, Atlantic Canada, Scotland, and Denmark. The outbreak in Chile in 2007 resulted in a significant economic loss. ISA affects brown trout and rainbow trout similarly to salmon. More cases of ISA have been found in saltwater environments, causing losses in sea-based farms. Studies in 2015 revealed instances of ISA in fish samples from the United Kingdom and British Columbia. For more information, check the provided references.
