This series reports on human activities that may impact aquatic ecosystems or components of those ecosystems, including the nature of the activities, their extent, their interactions with ecosystem components, and interactions with other human activities on the same areas. Generally, the effects...

The mean discharge (m3 s-1) of the Fraser River measured at Hope station. Presented as the mean discharge for an annual year (January through December) and for a flow year (April present year through March next year)....

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...

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...

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.
