The Ecosystem Status Report series reports on overviews of the status of ecosystems, oceanographic conditions, biological communities, and other integrative evaluations of status of areas, from local to very large spatial scales. Prior to 2003, the standard oceanographic conditions reports were...

This series documents the responses provided by DFO Science for issues handled via the Science Response Processes (SRPs). The SRPs are generally used when Science has to respond to urgent and unforeseen requests for scientific information / advice or to respond to a request for which advisory...

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...

This index measures the relative intensity of the Aleutian Low pressure system of the north Pacific (December through March). It is calculated as the mean area (km²) with sea level pressure <= 100.5 kPa and expressed as an anomaly from the 1950-1997 mean. A positive index value reflects a...

The Pacific Region ERAF provides a comprehensive approach for assessing all threats to marine ecosystems by evaluating cumulative risk from multiple activities to multiple ecosystem components for ecosystem-based management (EBM), improving upon international and national best practices in risk...

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...

This series documents the scientific basis for the evaluation of fisheries resources in Canada. As such, it addresses the issues of the day - in the time frames required for management - by providing progress reports on ongoing investigations. The research documents use scientific and technical...

This series documents the status of different stocks of fish, invertebrates and marine mammals in Canada as well as some ecosystem and environmental issues. From 1993 to 1996, and 2003 to 2004, Stock Status Reports were numbered by year and sequential number (i.e.: 1993/001). For 1997 to 2002,...

This index is the cumulative summation of negative northwesterly atmospheric circulation frequency anomalies: Z (westerly), M1, (northwesterly), and M2 (southwesterly) for December through March. An increasing trend in Pacific Circulation Index (PCI) reflects increased westerly and southwesterly...

Annual Summaries of Catch and Effort.

Statistics on commercial fishing licences issued by Fisheries and Oceans Canada in the Pacific Region. You will also find information collected through the registration of commercial fishing vessels. Data are available from 1985 onward.

The Proceedings Series contains publications which record the activities at meetings or workshops of which DFO is a sponsor. The Proceedings generally record decisions, recommendations, and major points of discussion at these meetings and workshops. Formats in the Proceedings Series are flexible,...

Data on freshwater fisheries are collected from multiple sources including DFO’s regional offices, provincial governments and other agencies. Species level landings data are provided by province and territory, on annual basis.

Data tables in this section present the commercial fisheries landings for the top 40 producing countries in the world. The data covers the period from 1990-2018 and are based on the most recent statistics available from the Food and Agriculture Organization of the United Nations (FAO).

Global exports of fish and seafood products by principal exporting countries from 1976 to 2018 in quantity and value terms, based on data collected by the Food and Agriculture Organization of the United Nations.

This study constitutes the first quantitative assessment of winter use of the northern Strait of Georgia by killer whales, which presents a substantial contribution to the limited knowledge of killer whale habitat use in British Columbia during the winter. Passive acoustic monitoring revealed...
