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 environment as well as responding to remedy the cause of the escape as soon as possible. When there is evidence that an escape event has occurred, licence holders must report the incident to the department within 24 hours either through the Observe Record and Report Line (ORR 1-800-465-4336), or to a dedicated email mailbox, detailing the cause, time and location of the event and the species, size and number of fish involved. The licence holder must also provide fish health information about the stock, such as exposure to therapeutants. A more detailed written report is then submitted to the department within seven days. DFO monitors BC waters for escaped Atlantic salmon through the Atlantic Salmon Watch Program (ASWP), which relies on voluntary reports from fish harvesters. A summary of [reports made to the ASWP](https://open.canada.ca/data/en/dataset/f0299fb3-73b9-4977-b96a-c83bd84ebdc4 "reports made to the ASWP") since July 2005 is available.

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. In addition to the monitoring and reporting required of licence holders, DFO staff biologists conduct field audits to collect and assess sediment samples and take video of the seafloor. This information is used to determine compliance and learn more about benthic impacts during different times of the production cycle. Further review and action may be required for sites with poor environmental performance or issues with non-compliance. For the results of benthic monitoring activities conducted by the industry, see [Results of industry benthic monitoring of BC marine finfish aquaculture sites](http://open.canada.ca/data/en/dataset/7e76fdc8-c36a-491a-9afb-4f9280c929e8 "Results of industry benthic monitoring of 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. 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. The DFO Sea Lice Audit Report shows the results of DFO’s random quarterly lice audits, which coincide with one of the licence holder's numerous scheduled counts. To assure quality, farm staff count lice on 50 per cent of the selected fish and DFO staff count lice on the other half.

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). In other words, if a zone contains 30 percent of the farms then 30 percent of the farms selected for audit would be randomly chosen from that area. This ensures equal probability of each farm being selected for sampling. To ensure confidence in the sample results, Fisheries and Oceans Canada endeavours to conduct fish health audits at 30 active farmsites per quarter, or approximately 120 each year. Farm audits are conducted in conjunction with the farm’s regularly scheduled carcass collection, allowing Fisheries and Oceans Canada staff access to the freshest of the dead fish. This approach of targeted disease sampling on recently dead fish increases the likelihood of DFO veterinarians finding disease, if present, and attributing an accurate “cause-of-death” diagnosis to each carcass gathered. The summary tables are updated quarterly to reflect Fisheries and Oceans Canada’s fish health monitoring activities. For the purpose of fish health monitoring, a site is considered “active” if the facility holds any salmonid for at least 30 days, and has a minimum of three fully stocked pens during the quarter in which sampling is to occur.

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 assesses industry reports and video data for compliance and uses the data to better understand benthic impacts. See [Results of DFO benthic monitoring audits of BC marine finfish aquaculture sites](http://open.canada.ca/data/en/dataset/c1a54a0c-4eb0-4b50-be1f-01aee632527e "Results of DFO benthic monitoring audits of BC marine finfish aquaculture sites").

Summary The Quebec region of the Department of Fisheries and Oceans (DFO) is responsible for the assessment of several fish and invertebrate stocks exploited in the Estuary and the northern Gulf of St. Lawrence. The commercial catches sampling program is one of the sources of information used to complete these assessments. The data collected by this program, at wharf or at sea, offers among other things the advantage of a relatively large spatio-temporal coverage and provides some of the necessary knowledge to assess the demography and the structure of the exploited populations. This program is implemented by specialized DFO staff whose main mandate is to collect biological data on groundfish, pelagic fish and marine invertebrate species that are commercially exploited in the various marine communities. Data This dataset on the Atlantic cod (Gadus morhua) includes the metadata, sample weight, fish length, the sex and the number of specimens measured. This dataset covers the period of 1983 to present. In order to protect the confidentiality of the sources, some informations (such as those concerning the vessel) have been excluded and others (such as the date of capture) have been simplified. Entries where there was only one vessel in a fishing area for a given year were also excluded. Further information including the fishing areas coordinates can be found by clicking on the «Atlantic and Arctic commercial fisheries» and «Fishing areas» links below.

The 2019 amended Fisheries Act (FA) contains a provision that will require DFO to have a public facing Registry to provide public access to records relating to fish and fish habitat protection and pollution prevention, including: • Ministerial agreements • Standards and Codes of practice • Ministerial orders • Fisheries Act Authorizations • Permits for designated projects • Fish habitat restoration plans This work supports the Government’s goals around transparency, access, and accountability in federal decision-making. The new online version of the [FA Registry](https://far-rlp.dfo-mpo.gc.ca/) is now available to Canadians. This latest release includes the Fisheries Act Authorizations (updated automatically.) The FA Registry is currently accessible through the [Common Project Search Portal](https://common-project-search.canada.ca/), a one-stop online location for Canadians to search and browse through DFO authorizations as well as projects and assessments submitted to the Impact Assessment Agency of Canada and Transport Canada. DFO will be undertaking continuous development of the Fisheries Act Registry. This release is the second step towards implementing the full FA Registry that will provide additional content as well as new features to the FA Registry, increasing transparency and proactive disclosure as well as improving digital capacity and service for Canadians.
