Striped Bass critical habitat (St. Lawrence estuary population) defined by the analysis of available knowledge in 2011 and a scientific advice.PurposeThe status of the Striped Bass population of the St. Lawrence Estuary is in constant evolution. It went from indigenous population until the end of 1960 to designated extirpated in Canada under the Species at Risk Act (SARA) in 2011.Still in 2011, the status of the population of the St. Lawrence Estuary was reassessed by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) following the Ministère des Ressources naturelles et de la Faune du Québec re-introduction efforts and was designated endangered (COSEWIC 2012). Under SARA, critical habitat must be designated for all threatened, endangered or extirpated species.Additional InformationThe analysis of available knowledge on habitat quality assessment and its use by the Striped Bass was realized using two research documents: Pelletier et al. (2010) and Robitaille (2010). These documents were then reviewed during a scientific peer review meeting in April 2010. A Recovery Strategy was also established in 2011.Pelletier, A.-M., G.

A list of all smallmouth bass and chain pickerel tournaments permitted under the Competitive Fishing Policy

PURPOSE:Scope the distribution of Smallmouth Bass in the Miramichi River Watershed using eDNADESCRIPTION:This dataset contains the results of work undertaken from 2019 to 2024 to scope the extent of the spread of Smallmouth Bass in parts of the Miramichi River Watershed using an eDNA-based species-specific qPCR approach.USE LIMITATION:To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.

Formerly known as the Nova Scotia Sportfish Registry, this dataset is a list of the current record holders for several popular Nova Scotia sportfish. There are both youth and adult, catch and release and catch and keep and smallmouth bass tournament categories.

The project (Quoddy Region Pelagics Telemetry) will support the assessment of the effects of aquaculture on the distribution and abundance of pelagic fishes (salmon, mackerel, herring) and large predators (shark, marine mammals) in Passamaquoddy Bay and the Bay of Fundy, an area of intense finfish culture. An acoustic receivers network is placed yearly (from April to December) across various passageways, locations of project-specific interest, and at aquaculture sites in the region. Tagged pelagic species will be tracked through the network to provide information on migration routes, movement speed, survival rates and suspected predators, and determine interaction and residence at aquaculture sites. The network was utilized for monitoring the passage of: hatchery-reared wild salmon (n=340) released in the Magaguadavic River in 2018, 2019 and 2021, wild alewives (n=30) from the St. Croix River in 2021, and farmed Atlantic salmon released in the wild (n=99) in 2021. The receiver network has more recently supported adjacent projects on the use of the region by white shark and porbeagle as well as the residence of mackerel, herring, and sculpin at farm sites. The receivers additionally support other researchers with detection of striped bass, Inner Bay of Fundy Atlantic salmon, sturgeon, and many other species. Placement of the network will continue into 2025 inclusive with the longer-term goal to eventually deploy an array covering the entrance to the Bay of Fundy.Cite this data as: Trudel, M., Wilson, B., Black, M. 2023.

PURPOSE:Provide presence/absence and abundance data for the non-indigenous and invasive European green crab (EGC) in selected southern Gulf of St. Lawrence (sGSL) estuaries along the Northumberland Strait coast of New-Brunswick and eastern Prince-Edward-Island.DESCRIPTION:Temporal monitoring during ice-free seasons of European green crab abundance is completed in response to previous regional population declines in the Maritime provinces. Note that where presence is not indicated on the map does not mean absence - this survey is limited to a few sites.Traps that did not fish correctly were not included in the dataset. Examples of defective traps include: an open trap, an open bait container, a trap filled with algae and falling into the open position, a trap that has not been fished for over 48 hours, an overturned trap, or a trap that has been significantly moved or otherwise tampered with.Population estimates are not derived from this data. PARAMETERS COLLECTED:1) EGC count, size measurement, sex, and catch weight2) Counts of bycatch species. Categories reported in this dataset are finfish (cunner, striped bass, mummichog, winter flounder, smooth flounder, sculpin, tomcod, American eel, banded killifish, flounder, unknown bony fish), Atlantic rock crab, American lobster, and other (lion's mane jellyfish, moon jellyfish, other crabs, moon snail). Other smaller species were often in the trap but were not included as bycatch in this dataset as they can easily escape the mesh size and would not consistently be trapped. 3) Environmental data: water depth at trap setting, sediment type, vegetation types noted, salinity, water temperature, dissolved oxygen (not included), specific conductance (not included), conductivity (not included), weather, cloud cover (not included), tide state and direction (upon fishing).NOTES ON QUALITY CONTROL:Data entry of morphological parameters randomly verified for accuracy.Weights are not reported for PEI sites due to inconsistencies with types of weighing scales and measurement protocols.PHYSICAL SAMPLE DETAILS:Whole European green crab specimensSAMPLING METHODS:Baited trapping with Fukui traps. Bait was in a bait can or bag. Types of bait included herring (predominant type used), as well as other species when herring were not available (gaspereau, canned fish [tuna, kippers, snack sardines], mackerel, tilapia, and perch).USE LIMITATION:To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.

PURPOSE:From August 1st to September 11th, 2014, Fisheries and Oceans Canada conducted a baseline survey of marine fishes and their habitats in the southern Canadian Beaufort Sea and Amundsen Gulf as part of the Beaufort Regional Environmental Assessment (BREA) called the Beaufort Sea Marine Fishes Project (BSMFP). Sampling was conducted from the F/V Frosti at 54 stations along 14 transects. Standardized sampling was conducted at pre-determined depth stations (20-1500 m) using benthic trawling nets. The BSMFP is the first research project to use large research trawls to assess the biodiversity and abundance of offshore marine fishes in this area. In total, 42 species of fish were caught. This report contains information on fishing net deployments, catch per unit effort (CPUE), and basic biological data for all fishes caught.DESCRIPTION:Basic biological data for all fish caught during the 2014 BSMFP expedition. Includes identification, weight, length (total, fork, and, standard), liver weight, gonad weight, sex and maturity level. PARAMETERS COLLECTED:familyspeciesweighttotal lengthfork lengthstandard lengthliver weightgonad weightsexmaturitySAMPLING METHODS:Various trawl types.

An exploratory project on the taxonomic and genetic diversity of decapods in three ocean subregions (Northeast Pacific, Canadian Arctic, and Northwest Atlantic), which were sampled in 2022, was undertaken by the Arctic Working Group under the Canada-U.S. Fisheries and Climate Collaboration between Fisheries and Oceans Canada (DFO) and the National Marine Fisheries Service (NMFS) of the National Oceanic and Atmospheric Administration (NOAA). This collaboration framework aims to pool Canadian and U.S. data to explore the impacts of broad-scale climate change on marine biodiversity. In early summer 2022, a sampling protocol with the selection of targeted decapods was provided to DFO and NOAA collaborators. Targeted genera were collected from a total of 10 research programs across three ocean subregions and four marine regions. The Northeast Pacific samples were collected in the Bering Sea during the Northern Bering Sea Ecosystem and Surface Trawl Survey, and the Eastern and Northern Bering Sea Continental Shelf Bottom Trawl Survey of Groundfish and Invertebrate Fauna onboard the F/V Northwest Explorer, F/V Alaska Knight and F/V Vesteraalen. In the Western Canadian Arctic (mainly from Beaufort Sea and Amundsen Gulf), specimens were collected during DFO’s Canadian Beaufort Sea – Marine Ecosystem Assessment (CBS-MEA) survey onboard the F/V Frosti. In Eastern Canadian Arctic (mainly from Baffin Bay and Davis Strait), specimens were collected during DFO’s Knowledge and Ecosystem-Based Approach in Baffin Bay (KEBABB) survey onboard the CCGS Amundsen and DFO’s North Atlantic Fisheries Organization (NAFO) Subarea 0B survey onboard the R/V Tarajoq. In the Estuary and Gulf of St. Lawrence (EGSL), specimens were collected from coastal surveys (scallops, sea cucumber, snow crab, and whelk surveys) onboard the CCGS Leim and offshore during the Ecosystemic Survey onboard the CCGS Teleost. Decapods were collected from various sampling gears (benthic beam trawl, modified Atlantic Western IIA otter trawl, Bacalao trawl, shrimp trawl, Digby scallop dredge, or modified sea cucumber dredge) and identified to the lowest possible taxonomic level and photographed, when possible. All specimens were frozen at sea (n = 995). In the lab, the identifications were validated or refined with the photos and the frozen specimens. DNA was extracted for 87 specimens and a section of COI gene was amplified in order to be sequenced using Sanger method. Sequences were compared with existing data using The Basic Local Alignment Search Tool (BLAST) in the National Center for Bio-technology Information Nucleotide database (NCBI-nt, including the GenBank database) to compare scientific names, where available.The present dataset includes 391 decapod species occurrences. DNA was extracted for a subset of 87 specimens (COI gene); sequences are publicly available on BOLD data portal under project code DDAO (see supporting document "citations_references.csv" for more information).The data are presented in Darwin Core format and are separated in three files:The "Activité_décapodes_DDAO_decapods_event_en" file contains information about missions, stations and deployments, which are presented under a hierarchical activity structure.The "Occurrence_décapodes_DDAO_decapods_en" file contains the taxonomic occurrences.The "ADN_décapodes_DDAO_decapods_DNA_en" file contains the DNA derived data.For further details, please refer to the technical report available in the supporting document named "citations_references.csv".

Fishing event (e.g., day, time, location, catch effort), and associated biological data from the Standardized Inlet Survey component of the annual Sablefish Research and Assessment Survey on the British Columbia coast.IntroductionDFO and the Canadian Sablefish Association undertake a collaborative fishery-independent annual research survey under a joint agreement. The survey employs longline trap gear to obtain catch rate data, gather biological samples, capture oceanographic measurements, and collect tag release and recapture data.Data summaries are provided here for standardized sets conducted at fixed stations within mainland inlets. The design of the sablefish survey has developed over time by incorporating and discontinuing components, including individual experimental studies (not available on OpenData). This Standardized Inlet Survey component differs in methodology from the other two survey components: (1) Offshore stratified random survey (2003 – present; available on OpenData using link below), and(2) Standardized trap survey – offshore indexing and offshore tagging (1990 – 2010; not yet available on OpenData). For the Standardized Inlet Survey, sets are allocated to five specific polygons in each of the following four inlet areas: Portland Inlet, Gil Island, Finlayson Channel, and Dean/Burke Channel. All four inlets were surveyed consistently between 2003 and 2019. No inlets were surveyed in 2020, and a single inlet was surveyed each year since 2021. Survey procedures are standardized and documented in Canadian Technical Reports of Fisheries and Aquatic sciences.Data tables provided for the Standardized Inlet Survey include (i) Effort, (ii) Catch, and (iii) Biological Information.Inlet EffortThis table contains information about annual survey trips and fishing events (sets). Trip-level information includes the year the survey took place, a unique trip identifier, the vessel that conducted the survey and the trip start and end dates (the dates the vessel was away from the dock conducting the survey). Set-level information includes the inlet name, date, time, location and depth that fishing took place, soak time, and number of traps deployed. All successful fishing events are included, where successful sets are those that met survey design specifications.Inlet CatchThis table contains the catch information from successful fishing events. Catch is identified to species or to the lowest taxonomic level possible. Catch is recorded as fish counts and / or weight. The unique trip identifier and set number are included so that catches can be related to the fishing event information (including capture location) for each set.Inlet Biological InformationThis table contains the biological data for sampled catches. Data may include any or all of length, weight, sex, maturity and age. Most of the sampled catch is Sablefish; however, some biological information has been collected for other species. Age structures are collected and are archived until required for analyses; therefore, all existing structures have not been aged. Tissue samples (usually a fin clip) may be collected for genetic (DNA) analysis for specific species. Tissue samples may be archived until required for analysis; for more information please see the data contacts. The unique trip identifier and set number are included so that samples can be related to the fishing event and catch information.
