The Ahousaht First Nation, Maaqutusiis Hahoulthee Stewardship Society and Cermaq Canada are proud to share the results of years of collaborative advancement in sea lice management of Cermaq Canada’s operations in Ahousaht Territory, where a full production cycle of salmon having been grown to harvest without the need for sea lice treatment using mechanical delousing has just been completed. In 2022, Cermaq Canada conducted 56 mechanical delousing treatments to maintain an annual lice level of 1.93. DFO regulations stipulate that sea lice levels must be below the threshold of 2.8 motile lice during the outmigration. Ahousaht’s Protocol Agreement with Cermaq Canada stipulates that sea lice levels must not exceed 1.5 motile lice during the outmigration and 2.5 lice through the remainder of the year. Sea lice are naturally occurring parasites of wild and farmed salmon.
