Commercial catches sampling program in the Estuary and Gulf of St. Lawrence – Arctic Lyre Crab (Hyas coarctatus)
SummaryThe Quebec region of the Department of Fisheries and Oceans (DFO) is responsible for the assessment of several fish and invertebrate stocks exploited in the Estuary and the northern Gulf of St. Lawrence. The commercial catches sampling program is one of the sources of information used to complete these assessments. The data collected by this program, at wharf or at sea, offers among other things the advantage of a relatively large spatio-temporal coverage and provides some of the necessary knowledge to assess the demography and the structure of the exploited populations. This program is implemented by specialized DFO staff whose main mandate is to collect biological data on groundfish, pelagic fish and marine invertebrate species that are commercially exploited in the various marine communities.DataThis dataset on the Arctic Lyre Crab (Hyas coarctatus) includes the metadata, sample weight, specimen weight, the shell width, the shell state, the height of the right claw and sex. This dataset covers the period between 2002-2021. In order to protect the confidentiality of the sources, some informations (such as those concerning the vessel) have been excluded and others (such as the date of capture) have been simplified. Entries where there was only one vessel in a fishing area for a given year were also excluded. Further information including the fishing areas coordinates can be found by clicking on the «Atlantic and Arctic commercial fisheries» and «Fishing areas» links below.

Traditional knowledge of nearshore fisheries for the southern Gulf of St. Lawrence (1994-1997)
In 1998, Fisheries and Oceans Canada (DFO) published an atlas called "Traditional Fisheries Knowledge for the Southern Gulf of St. Lawrence". The document is composed of a series of maps that contain useful information primarily on nearshore fisheries and fish habitat in the eastern shore of New Brunswick, Prince Edward Island and the Gulf Shore of Nova Scotia. It was used as a working tool to assist in the development of integrated coastal zone management plans, resource management plans, and more.Between 1994 and 1997, data collectors and fishery officers interviewed local fishers and industry representatives. The purpose of these interviews was primarily to gain information on local fishing activities and the location of fisheries' resources and their habitats. The data and information was vetted through a process of verification with scientists, fishers, locals, industry representatives, and government officials. Maps were then compiled for 14 commercially important fish species and made publicly available to consult. These include lobster, rock crab, scallop, snow crab, toad crab, herring, mackerel, American plaice, cod, witch flounder (grey sole), hake, halibut, winter flounder, and unspecified groundfish. This data resource also includes the other 27 species originally not included in the atlas.
Caribou Herd Locations for BC
This data contains the current caribou subpopulation (herd) boundaries. Herd boundaries are derived from the best available science and expert knowledge. A caribou subpopulation (herd) boundary is the area required to be managed to achieve a self-sustaining population. Subpopulation boundaries do not overlap even though some caribou subpopulations share portions of their annual range. *This dataset is the focal point of the Caribou in British Columbia - Web Application.
Winnipegosis Isopach
These structure, isopach and zero edge files are part of a series of stratigraphic framework maps for the Saskatchewan Phanerozoic Fluids and Petroleum Systems (SPFPS) project.The series of stratigraphic framework maps for the Saskatchewan Phanerozoic Fluids and Petroleum Systems (SPFPS) project have been produced using 2 km equi-spaced modified grids generated from Golden Software’s Surfer 9 kriging algorithm. The dataset used to produce each of the maps in this series was created using data from several projects completed by the Ministry (Christopher, 2003; Saskatchewan Industry and Resources et al., 2004; Kreis et al., 2004; Marsh and Heinemann, 2006; Saskatchewan Ministry of Energy and Resources et al., 2007; Heinemann and Marsh, 2009); these data were validated and edited as required to facilitate correlations between the various regional projects. In addition, to minimize edge effects during contouring, the senior author also generated stratigraphic data from wells in adjacent jurisdictions.

Pacific Recreational Fishery Salmon Head Depots
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 are injected into the nose cartilage of juvenile salmon prior to ocean migration. Annually, Canada and the United States tag over 50 million juvenile salmon. Fisheries and Oceans Canada applies about 5.5 million tags, using about 5.5 kilometres of wire. Anglers can recognize the presence of a coded-wire tag because of the missing adipose fin (located on the dorsal surface of the salmon). If you have caught an adipose fin clipped Coho and Chinook, it is a simple matter of removing the head from the fish, completing a sport head label and then submitting the head to a Sport Head Recovery Depot in the area. It is just as important to turn in heads from terminal or freshwater sites as it is from marine areas. Even though anglers fishing close to hatcheries can be fairly certain of the origin of their catch, data will not be recorded unless the heads from fin-clipped recoveries are turned in. Without the data, the health of the stock and the value of the resource to anglers could be underestimated.

Biodiversity of the Benthic Epifauna Trawl Survey from KEBABB program (2021)
This resource documents a dataset of epifauna occurrences collected in 2021 during The Knowledge and Ecosystem-Based Approach in Baffin Bay (KEBABB) program developed by the Department of Fisheries and Oceans Canada (DFO) in collaboration with university partners. The overall objective of KEBABB is to characterize the variability and trends in physical, chemical, and biological oceanographic conditions and food webs supporting fisheries in the connected ecosystems of western Baffin Bay and Lancaster Sound. In 2021, DFO expanded the KEBABB program to Barrow Strait (KEBABS-Knowledge and Ecosystem-Based Approach in Barrow Strait), a key productive area of the Tallurutiup Imanga National Marine Conservation Area. The study took place in the Eastern Canadian Arctic (mainly in Baffin Bay, Davis Strait and Barrow Strait). Sampling is done along transects at fixed stations in the study area. Catches are collected with a 1.5 m Agassiz trawl (5 mm mesh net) for 3 minutes bottom-contact time at a target speed of 1.5 knots and with a 3 m benthic beam trawl (6.4 mm mesh net) for 15 minutes bottom-contact time at a target speed of 3 knots. A total of 16 stations were sampled for epifauna in 2021 between 85-850 m depth. Epibenthic invertebrates are identified to the lowest possible taxonomic level and photographed. All unknown specimens are frozen. In the lab, the identifications are validated or refined with the photos and the frozen specimens.The data are presented in Darwin Core and are separated in two files:The “Activité_épifaune_KEBABB_epifauna_event_en” file which contains information about missions, stations and deployments, which are presented under a hierarchical activity structure.The “Occurrence_épifaune_KEBABB_epifauna_en” file that contains the taxonomic occurrences.Further details on sampling can be found in the following report: Pućko, M., Charette, J., Tremblay P., Brulotte S., St-Denis B., Ciastek S., Hedges, K., Kuzyk, Z., Roy V., and Michel, C. 2022.
