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 sustainable aquaculture by maintaining healthy ecosystems. All operational sites must be monitored at peak production, when the greatest environmental impact is most likely to occur. If the thresholds outlined in Aquaculture Activities Regulations are exceeded, the site must be fallowed (left empty) until further monitoring shows the seabed has sufficiently recovered.
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.
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.
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.
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.
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.
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.
Jasper National Park uses a reference condition approach to monitor benthic macroinvertebrates in the stream and river ecosystems within the park. The taxonomic counts of the benthic macroinvertebrates from test sites are compared to that of the reference sites.
Fish health on British Columbia salmon farms is managed throughout the production cycle to maintain healthy fish populations and to identify and address disease occurrences as soon as they arise. Aquaculture licence conditions set out mandatory monitoring and reporting requirements to ensure any potential impacts are appropriately mitigated at salmon farms. A central component of on-farm fish health management is a Fish Health Management Plan (FHMP). FHMPs are approved by Fisheries and Oceans Canada (DFO) and describe the fish health principles that the licensee must follow to maintain fish health and biosecurity at the farm.
This dataset contains monitoring data for benthic invertebrate communities along the Thompson River Corridor. The raw data in this dataset is used to calculate benthic invertebrate richness and the percentage of Ephemeroptera (mayflies), Plecoptera (stoneflies), and Trichoptera (caddisflies) (EPT) species (some of the most important species that indicate a healthy system). The data is collected annually in early-July at pre-determined sites along the Thompson River. Full benthic invertebrate sampling and habitat assessments are completed in accordance with CABIN protocols.
