Stimpson's surfclam or Arctic surfclam (Mactromeris polynyma) concentration areas in this layer are described as being known and commercially exploited historically and/or currently. The mapping of these areas is based on several sources of information: exploratory fisheries, scientific surveys...

Tow, catch, and length frequency for fish caught during the August sentinel surveys in the southern Gulf of St. Lawrence (NAFO Division 4T). Abundance indices and spatial distribution patterns of commercial groundfish. Note: Due to delays caused by logistic complexities and Covid the project...

The selection of an Area of Interest (AOI) marks the beginning of the Oceans Act Marine Protected Area (MPA) establishment process led by Fisheries and Oceans Canada. The process includes completing detailed ecological and socioeconomic assessments, setting conservation objectives, determining...

This dataset contains the abundance (per m²) and the biomass (mg dry per m²) of macrofauna (≥ 500µm) in eelgrass and adjacent bare soft sediments, collected at sites in the Atlantic of Nova Scotia from 2009 to 2013. Cite this data as: Wong M.C. Data of Benthic invertebrates in seagrass and bare...

Created in 2005, Science Advisory Reports include traditional Stock Status Reports, Ecosystem Status Reports, and Habitat Status Reports. Moreover, management strategies, frameworks and guidelines on the assessment or evaluation on specific issues, impacts of human activities on ecosystem...

The Atmospheric Forcing Index (AFI) utilizes standardized scores of the first component from a principal components analysis on the Aleutian Low Pressure Index (ALPI), Pacific Interdecadal Oscillation Index, and the northwesterly atmospheric circulation anomalies for the North Pacific (December...

Data from drifters with deep drogues collected by the Institut für Meereskunde, at the University of Kiel from 1980 to 1996.

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...

List of Publications from the Pacific Biological Station and related staff (not including (IOS)).

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 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 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...

Total number of transects surveyed and total number of lobsters measured for each site in each year. There are some sites that do not have any coordinates identified, therefore these have not been included in the Web Map Services (WMS).

To better understand patterns of temporal and spatial variation of fish assemblages in offshore waters of Lake Winnipeg (Manitoba, Canada), pelagic trawl tows were conducted at lakewide monitoring stations since 2002. Trawl samples collected during spring, summer, and fall from the south basin,...

Identification of significant concentrations of sea pens in the Gulf of St. Lawrence biogeographic unit using Kernel density estimation (KDE). This method was applied to create a modelled biomass surface for each taxa and an aerial expansion method was permitted to identify significant...

The purpose of this study was to characterize the kelp bed at Batture-aux-Alouettes, a preferred food source for the green sea urchin (Strongylocentrotus droebachiensis). The green urchin is fished commercially in Quebec and the fishing effort is concentrated on the Batture-aux-Alouettes near...

The Department of Fisheries established a survey of demersal juvenile Atlantic cod (Gadus morhua) in the nearshore (<10 m deep) in 1959. This survey aimed to characterize the distribution and abundance of juvenile Atlantic cod and was based upon Norway's Flodevigen sampling program which has...
