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 measures (e.g., treatment, quarantine, reduction in density). As a condition of licence, company veterinarians must notify DFO within seven days of any fish health event on a farm and provide a preliminary or confirmed farm-level diagnosis as well as details on any sampling, monitoring or mitigation measures planned or performed. Historical data are available from 2016 to the present.
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) must determine the probable cause of the event and develop a plan to mitigate ongoing harm to the farmed fish and reduce any risk to wild fish. Companies must continue to update Fisheries and Oceans Canada (DFO) every 10 days for the duration of the mortality event, including daily mortality counts, mitigation applied, determination of the cause(s) of the event and any updated plan.
For health auditing purposes, a farm is considered active once three pens of fish have been present for 30 days, following entry of the first pen of fish at the farm. Fisheries and Oceans Canada (DFO) applies a computerized selection system to randomly select active salmon farms within the fish health zones of the British Columbia. coast. All farms within a zone are assigned a random number and a computer selection of the farms within that zone is weighted (based on the fish species and the number of “active farms” operating in that zone as a percentage of the total number of active farms in the province).
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 operators and Fisheries and Oceans Canada staff quickly assess whether disease may be present. Facility operators report mortalities in a number of categories that describe either the cause of death or the condition of the carcass.
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 isolated by culture, and whether a pathogen or disease has been confirmed by histopathology (microscopic examination). DFO veterinarians provide a farm-level diagnosis and identify any conditions of note based on these laboratory findings and any other information collected during the fish health audit or reported by companies as a condition of licence. The terminology used in the report’s column headings can be found in the terminology file below.
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 and transfer events. This information is submitted to DFO and public reports are posted quarterly. The tables provided list the reported incidental catch of dead wild finfish and the year and month in which they were captured from B.C.
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.
Fisheries and Oceans Canada (DFO) issues licences under Section 56 of the Fishery (General) Regulations to authorize the intentional release and transfer of live aquatic organisms into fish-bearing waters or fish-rearing facilities. The federal-provincial Introductions and Transfers Committee (ITC) reviews applications to assess risks for possible disease, ecological and genetic effects on native species and ecosystems. When issuing a licence, the ITC may also prescribe certain measures to minimize risks associated with transfer activities, such as egg disinfection or quarantine of stock. DFO regulates the aquaculture industry in British Columbia so that the introduction and transfer of fish and shellfish into and between facilities does not adversely affect local aquatic species and habitats.
Fishing licences sales by county for both general and salmon fishing
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 management. The results of industry’s sea lice assessments of Atlantic salmon are provided to DFO monthly and posted to this website quarterly. DFO biologists and veterinarians conduct regular assessments throughout the year to verify the accuracy of licence holders’ procedures and reporting.
