Well, it varies from year to year. In the worst years, when the infestations were the most intense, the prevalence of sea lice was up to 99% in some locations, with the number of lice per fish reaching 80, 90, or over 100 lice per juvenile salmon. Those numbers, obviously, are lethal.
In other years, when there were fewer farms that were active or where chemical treatment or other management actions reduced the number of lice on the farms, we saw more moderate levels of infestation: 30%, 40%, and 50% as well. It's variable from year to year.
