Polygons denoting concentrations of sea pens, small and large gorgonian corals and sponges on the east coast of Canada have been identified through spatial analysis of research vessel survey by-catch data following an approach used by the Northwest Atlantic Fisheries Organization (NAFO) in the...

Acoustic telemetry allows detailed observations of the movement behaviour of many species and as tags get smaller, smaller organisms may be tagged. The number of studies using acoustic telemetry to evaluate marine invertebrate movement is growing, but novel attachment methods include unknowns...

The shallow, coastal regions of the world’s oceans are highly productive ecosystems providing important habitat for commercial, forage, endangered, and iconic species. Given the diversity of ecosystem services produced or supported by this ecosystem, a better understanding of its structure and...

Spatial distribution of the relative occurrence of Spotted Wolffish in the annual DFO groundfish research surveys conducted by the Québec (1978-2008) and Gulf (1971-2008) regions. Catch and effort data were aggregated by 100 km² cells. The probability of catching an Spotted Wolffish in a set...

Spatial distribution of lumpfish catch rates (number per tow) during the August DFO research survey conducted annually since 1990, to assess the state of groundfish and shrimp stocks in the northern Gulf of St. Lawrence. The area sampled by a tow is the product of the distance trawled (fishing...

The layer provides information on suspended particulate matter (SPM) concentrations by area. There is a natural interaction phenomenon between hydrocarbons and SPM, that creates hydrocarbon-SPM aggregates. The SPM in the water column, hence has an effect on hydrocarbon capacity to sink to the...

From August 5th to September 3rd, 2012, Fisheries and Oceans Canada conducted a baseline survey of marine fishes and their habitats on the Canadian Beaufort Shelf and slope. Sampling was conducted from the F/V Frosti at 28 stations along four transects. Standardized sampling was conducted at...

Catch, effort, location (latitude and longitude), and associated biological data from groundfish multi-species longline surveys on the southern British Columbia coast, excluding the inlets and protected waters east of Vancouver Island. Introduction The Outside South Hard Bottom Longline...

Location and contact information for Pacific Recreational Fishery Salmon Head Recovery Depots. The sport fishing community has an important role in the recovery of coded-wire tags found in Coho and Chinook. A coded-wire tag is a 1mm piece of wire that is laser etched with a unique number. Tags...

Layer that includes the known information on potential haul-out sites for the harbour seal and gray seal in the Estuary and Gulf of St. Lawrence according to a literature review of documents produced between 1978 and 2000. Additional Information Potential haul-out sites for the harbor seal...
