Scottish Sea Farms group, in which SalMar owns a half share with the Leroy Seafood, saw its harvest fall by more than 3,000 tons during the final quarter of 2025, figures show today.
The output was 5,500 tons against 9,000 tons over the same period in 2024.

Scottish Sea Farms suffered biological challenges at a number of sites which led to incident-based mortality, primarily related to amoebic gill disease.
SalMar said that weak results in the period following biological challenges at a number of sites which led to incident-based mortality primarily related to AGD gill health challenges.
Lower average of harvested biomass affected both cost and price achievement.
The operational and biological performance improved at the end of the period. Volume guidance for 2026 has been reduced by 2,000 tons to 43,000 tons due to the biological challenges it has been experiencing.
SSF generated revenue of NOK 575 million (£44m) against NOK 965 million (almost £74m) a year earlier.
SalMar’s share of Scottish Sea Farms’ net profit was, in fact, a loss of NOK -86 million (£6.4m) in the October to December 2025 period.
The EBIT per kilo gutted weight was (minus) NOK -33.8 in the period, a decrease from NOK 10.3 per kg in the corresponding period last year.
