Algae blooms are killing off salmon in Norway

The Norwegian Directorate of Fisheries has issued warnings that toxic algae blooms (Chrysochromulina leadbeaterii) are affecting an area of about 450 kilometres of the northern coastline of Norway.

More than 10 000 tonnes of farmed salmon have died so far valued at a loss of 620 million NKR (63 million EUR) and more are expected in the near future. The Directorate is working on possible solutions for farmers including the use of well boats to relocate the fish. The algae is not uncommon in these waters during spring but the sheer size of the blooms are proving mortal to the fish.
