A deadly algae that kills farmed salmon is still spreading.
So far, 10,600 tonnes of fish have died in Nordland and to the south of Troms.
The figures from the Directorate of Fisheries are a preliminary calculation. Because of the algae, the fish farmers who have been affected have not had the capacity to report accurate figures on how many fish they have lost and how big the losses are.
The breeders in Troms have not reported mortality rates since the 17th of May. In Nordland there is still high mortality and several new sites have been affected.
‘’The forecasts for the coming days are caused by outgoing water flow from the Ofotfjorden, which means that several facilities in the outer parts of the fjord are in danger. There are still reports of mortality in middle and inner parts’’ reported the directorate of fisheries.
Algae of the genus Chrysochromulina were found in water samples from both counties. This is a common algae, but in conditions that are particularly good for the algae it can bloom in large numbers and be fatal to fish.
