As a part of its preventive fish health strategy through regular testing, farmed salmon supplier Cermaq detected the infectious salmon anemia (ISA) virus in fish in two pens at its Langøyhovden farm in Nordland, Norway.
The company said mortality at the site is low and there are no clinical signs of outbreak. Cermaq Norway is considering culling the fish in the two affected pens to prevent spread of infection to the remaining fish at the site.
Following an ISA outbreak at other farming operators' sites in the region, Cermaq has monitored its operations with regular testing. Cermaq has informed the Food Authority.
The Langøyfjord site contains approximately 660,000 fish of an average live weight of 2.6 kg. Out of these 173,000 fish will be culled. The culling of 173,000 fish at the Langøyhovden site is expected to have only limited financial impact.
The control of the fish at the site will continue harvesting will be done in agreement with the Food Authority.
