The prevalence of sea lice on juvenile wild salmon in 2015 was the highest it has been in five years, but the outbreak does not appear to be associated with salmon farming, according to a report from the B.C. Salmon Farmers Association. Many of the most intense infestations were found in areas that had no active salmon farms or that had never been used for salmon aquaculture, according to data in three technical reports on Broughton Archipelago, Quatsino Sound and Queen Charlotte Strait. Fisheries researchers examined more than 2,600 fish from 52 sites.
