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. Licence holders must submit a Health Management Plan to DFO that includes sea lice...

Fisheries and Oceans Canada requires operators of active marine finfish aquaculture sites in British Columbia to monitor for benthic (seabed) impacts. The benthic monitoring program is designed to limit the location, area, and intensity of impact created by fish farms to the seabed and to support...

This report provides summary fish health data collected by Fisheries and Oceans Canada (DFO) from randomly selected licensed marine facilities culturing salmon in British Columbia (BC). Results of polymerase chain reaction (PCR) screening are provided, as well as a list of the bacterial pathogens...

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...

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...

Mortality at salmon aquaculture facilities is closely monitored. If the amount of dead fish at a farm exceeds thresholds outlined in conditions of licence, a mortality event is said to have occurred and must be reported to DFO within 24 hours of discovery. Facility managers and veterinarian(s)...

This report provides a summary of fish health events reported by aquaculture companies to Fisheries and Oceans Canada (DFO). A fish health event is any suspected or active disease that occurs within an aquaculture facility that requires the involvement of a veterinarian and warrants mitigation...

Fisheries and Oceans Canada’s (DFO’s) Conditions of Licence for finfish aquaculture include requirements to minimize harm to wild fish that swim into facilities. Facility operators must also maintain an incidental catch log, which is a record of wild fish caught at the facility during harvest...

Mortality at salmon aquaculture facilities is closely monitored. As in any population of wild or farmed animals, there are a number of causes leading to death. While in-depth diagnostic testing takes time, carcasses are routinely assigned to a number of defined categories which can help facility...

Fisheries and Oceans Canada’s (DFO’s) Pacific Aquaculture Regulations and Conditions of Licence for aquaculture in B.C. require licence holders to take various fish escape prevention measures, including maintaining infrastructure in a manner to prevent the escape of farmed fish into the...

Marine mammal predator control is governed by the Marine Mammal Regulations under the Fisheries Act. Records of marine mammal mortalities are maintained and results reported publicly. Additional licences can be obtained for control of other species. Fisheries and Oceans Canada works with industry...

The Olympia oyster (Ostrea lurida Carpenter, 1864) is one of four species of oysters established in British Columbia (BC), Canada, and the only naturally occurring oyster in BC (Bourne 1997; Gillespie 1999, 2009). O. lurida reaches the northern limit of its range in the Central Coast of British...

This data set is a generalized characterization of the offshore and inshore environments of Canada’s Pacific Ocean. Compiled from various sources to depict the biogenic habitats, pelagic habitats, and general bottom types such as offshore and inshore by depth strata.

Fisheries and Oceans Canada has conducted a cumulative human impact mapping analysis for Pacific Canada to support ongoing Marine Spatial Planning. Cumulative impact mapping (CIM) combines spatial information on human activities, habitats, and a matrix of vulnerability weights into an intuitive...

A Conservation Unit (CU) is a group of wild Pacific salmon sufficiently isolated from other groups that, if extirpated, is very unlikely to recolonize naturally within an acceptable timeframe, such as a human lifetime or a specified number of salmon generations. Holtby and Ciruna (2007)...

This dataset provides 30-year, 50-year, and 100 year return levels for small craft harbours in British Columbia, relative to the mean sea level over 1993-2020. The return levels are derived from coastal sea levels for the period from 1993 to 2020, simulated using a high-resolution Northeast...
