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...

Catch, effort, location (latitude, longitude), and associated biological data from groundfish multi-species longline surveys in British Columbia. Introduction This is a set of long-term and coordinated surveys that together cover most of the nearshore, hard-bottom habitat of coastal British...

This record contains data on bowhead whale locations reported in Harwood, L.A. and P. Norton. 1996. Aerial survey data from the southeast Beaufort Sea, Mackenzie River estuary and west. Amundsen Gulf, July 1992. Canadian Data Report of Fisheries and Aquatic Sciences No. 964

Spatial distribution of the Smooth Skate presence expressed by catch weight based on the annual Department of Fisheries and Oceans (DFO) groundfish research surveys realised between 2004 and 2010. Catch data (kg/nautical mile) were aggregated by 100 km² cells. They are derived from processed...

Aquatic invasive species pose economic and ecological threats to Canada's coastal waters. In response, Fisheries and Oceans Canada (DFO) has established monitoring programs to detect and track the spread of aquatic invasive species, including European Green Crab, in Canadian waters. Fukui traps...

Conservation of marine biodiversity requires understanding the joint influence of ongoing environmental change and fishing pressure. Addressing this challenge requires robust biodiversity monitoring and analyses that jointly account for potential drivers of change. Here, we ask how demersal fish...

Catch, effort, location (latitude and longitude), and associated biological data from the Hecate Strait Multispecies Assemblage Bottom Trawl Surveys in Hecate Strait, British Columbia. Introduction The Hecate Strait Multispecies Assemblage Bottom Trawl survey series consists of twelve...

Between 2017 and 2019, Fisheries and Oceans Canada conducted a baseline survey of marine fishes and their habitats on the Canadian Beaufort Shelf and slope in August and early September each year. Sampling was conducted from the F/V Frosti at 144 stations along nine multi-year transects, and 32...

The Beluga whale critical habitat, which includes the Upper Estuary, the Saguenay River up to Sainte-Marguerite Bay, and the southern channel of the Lower Estuary, supports the vital functions of calving and rearing of the young. Due to the lack of information, studies are planned in the near...
