Norway's fish farmers spent record levels battling sea lice last year said Nofima

Salmon lice costing Norway NOK 5 billion a year

The task of tackling salmon lice cost Norway’s aquaculture industry more than five billion kroner, or some £440 million last year, a leading researcher has calculated.

Audun Iversen, who works at Nofima, the Norwegian Institute for Food, Fisheries and Aquaculture Research, says the figure, which he has worked out at NOK 5.2 billion, had reached a record level and is considerably higher than the figure for 2017.

He also believes there were additional indirect costs which he has not included in his calculations, but which were quite significant.

Lice is affecting nearly all areas of fish farming in Norway, he reports. Some of the biggest cost increases centre around using larger smolt in order to reduce production time at sea, and therefore the time fish are exposed to the possibility of lice.
