Industry sea lice counts at BC marine finfish aquaculture sites

Fisheries and Oceans Canada’s (DFO’s) conditions of licence for marine finfish aquaculture contain monitoring and intervention requirements to minimize the potential exposure of wild and farmed fish to sea lice. The Industry Sea Lice Abundance Counts report is updated monthly. It shows which Atlantic salmon farms were actively raising fish during the month and the results of industry's monthly sea lice monitoring.

Please see the Open Data page for DFO sea lice audits of BC marine finfish aquaculture sites to see data from 2011 to 2015.
