Sea lice mitigation events at BC marine finfish aquaculture sites

Sea lice mitigation events at BC marine finfish aquaculture sites This report provides a summary of sea lice mitigation events reported by marine finfish aquaculture companies in British Columbia to Fisheries and Oceans Canada (DFO). A sea lice mitigation event is any measure that is used to bring the sea lice abundance at a facility below the threshold of three motile salmon lice (*L. salmonis*) per fish. These mitigation measures include in-feed, mechanical removal, medicinal or non-medicinal bath treatments, or harvest. Salmon farmers must monitor the effectiveness of treatments and report reduced efficacy to the Department.
