The disease was detected during routine screening.
Norwegian salmon farmer Måsøval has detected the ISA virus during a routine screening at its Fjølværet farming site in Frøya Municipality.
While confirmation is pending further testing, the company is treating the detection as confirmed and has implemented strict measures to contain the virus and prevent further spread.
The site houses 396,000 fish with an average weight of 5.6kg WFE. Måsøval will harvest the site to reduce biological risk, the company announced in a press release on Monday.
This change in the harvest plan is expected to have limited impact on volumes and costs, and is anticipated to have little effect on price achievement, as the site was originally scheduled for full harvest in week 26.
