In 2002, the number of pink salmon returning to the Broughton Archipelago was only 3% of normal. Alexandra Morton subsequently co-authored a study reporting that 68 – 98 % of the fish tested in this area had the sea louse “L. salmonis.”1 A University of Toronto study links the 2015 sea lice epidemic to fish farms in the same area. The article that follows is based on Marine Harvest Canada’s (MHC) Ian Roberts’ response to anti-salmon farm critics.
