Norwegian salmon farmer Måsøval has reported a suspected outbreak of Infectious Salmon Anemia (ISA) at two of its sites, Espnestaren (site number 32677) and Måøydraga (site number 12370) in Frøya Municipality, Norway.
The suspicion arose following routine screenings that indicated positive results for ISA. Confirmation of the virus is pending further testing, but the company is treating the situation as a confirmed case in the interim.
Strict containment measures have been implemented, and relevant authorities have been notified. If ISA is confirmed, Måsøval may accelerate the harvest of affected sites, with the timeline dependent on the disease’s progression, logistics, and harvesting capacity.
Espnestaren currently holds approximately 1.1 million salmon with an average weight of 3.4 kg, while Måøydraga contains about 274,000 salmon with an average weight of 3.8 kg.
The potential impact of the suspected ISA has led Måsøval to revise its 2024 harvest guidance from 27,000-28,000 GWT to 26,500-27,500 GWT.
