Around 10,000 salmon, weighing a total of 20 tonnes, were found dead earlier this month at Isqueen’s Eidisholman site in Vestvågøy, Lofoten.

The deaths are believed to have been caused by hydrogen sulphide (H₂S), a toxic gas linked to unusually high summer temperatures and stagnant water conditions, according to Norwegian media outlet Lofotposten.

Production manager Henrik Svendsen told Lofotposten that the deaths were likely triggered by the “period of unusually high summer temperatures” and reduced water flow in the facility due to calm seas. He confirmed that the situation is “now under control, thanks to the quick and targeted efforts of our skilled employees, veterinarians, and fish health personnel.”

Sediment samples taken at the site confirmed a strong smell of H₂S, which poses an acute danger to salmon. The gas, often associated with RAS plants, was detected in this marine facility, raising concerns about environmental conditions. Svendsen added, “We are following the situation closely,” to ensure there are no further issues.
