Cumulative mortality in Norwegian salmon farms amounted to 8.7 percent during the first nine months of the year, compared with 10.7 percent in the corresponding period of 2025, according to Veterinærinstituttet. A total of 30.4 million salmon deaths were reported.
Mortality decreased in most production areas, with particularly large improvements in areas 9 and 11.
In areas 1 and 2, however, mortality rose from 12.2 to 20.2 percent following an algal bloom during the first quarter.
