Norway Royal Salmon (NRS) has culled all the fish at one of its farm sites due to the detection of Parvicapsulose disease, caused by the parasite Parvicapsula.

The site, at Elva in Alta municipality, has 0.8 million triploid fish with an average weight of 0.65 kilos, with the cull being made for what NRS describes as welfare reasons.

"The incident will have an impact on the result of the third quarter of 2022 and will reduce NRS's expected harvest volume for 2022 by around 2,000 metric tons to 30,000 metric tons.
