Fish farming company Grieg Seafood lowers its forecast for 2026 after elevated mortality at a farming facility in September, caused by an unexpected algae occurrence that damaged the fish’s gills.
The biomass loss is estimated at approximately 1,000 tonnes. The harvest volume forecast is lowered to 29,000 tonnes from 31,000 tonnes, and the farming cost is raised to 71 Norwegian kronor per kilo from 67.5.
The incident is not expected to affect production in 2027.
