The files give magnified photos of 1,838 eel otoliths that have been prepared for age reading. Samples are from the Atlantic Provinces of Canada. Individual otolith codes in Cairns2020_AnnexB_EelLengthsAgesEfishingRecords.xlsx and in Cairns2020_AnnexC_EelLengthsAgesDataDefinitions.csv match the codes embedded in otolith image filenames. PARAMETERS COLLECTED:American eel landings, number caught, and effort of commercial and research fishing gear. American eel lengths, ages, sex and other biological data and sampling locations.NOTES ON QUALITY CONTROL:All keypunched records of landings, densities, and other data were verified against original sources. Landings and abundance indices were reviewed in a Department of Fisheries and Oceans scientific workshop and corrected as necessary. Length and age data were examined by length-weight and length age plots and implausible records were discarded.PHYSICAL SAMPLE DETAILS:No physical samplesSAMPLING METHODS:Landings are from government fisheries agencies.Abundance indices are from commercial fyke, spear, and trap catch per unit effort, and from research ladder counts and electrofishing records.Mean elver lengths are compiled from published literatureSex ratios are compiled from published literatureLocations of biological and genetic sampling are compiled from published literatureAmerican eel lengths are total length of live specimens. Ages are from otolith annulus readingsElectrofishing records are from backpack electrofishing surveys in wadeable watersUSE LIMITATION:To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.

PURPOSE:To track juvenile Atlantic salmon densities.DESCRIPTION:Indices of freshwater production are derived annually from electrofishing surveys in the Miramichi River of New Brunswick. Juvenile salmon abundances at sites, in terms of number of fish per habitat area sampled by age or size group (densities), are obtained using successive removal sampling or catch per unit effort sampling calibrated to densities. Sampling intensities vary among years and among rivers. PARAMETERS COLLECTED:Species counts (ecological); point (spatial).USE LIMITATION:To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.

PURPOSE:To monitor juvenile Atlantic salmon densities over time.DESCRIPTION:Indices of freshwater production are derived annually from electrofishing surveys in Southeast New Brunswick. Juvenile Atlantic salmon abundances at sites, divided by age or size group and reported in terms of number of fish per habitat area sampled (density), are obtained using successive removal sampling or catch per unit effort sampling (which is calibrated using successive removal sampling data). Sampling intensities vary among years and among rivers.This dataset comprises raw data on all fish captured and effort invested in the course of monitoring juvenile Atlantic salmon in Southeast, New Brunswick, from 1974 to 2024. Sampling was focused on habitat suitable for Atlantic salmon, and capture of any other species was incidental. PARAMETERS COLLECTED:Distribution (ecological); species counts (ecological); fish lengths (biological); fish weights (biological); point (spatial).USE LIMITATION:To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.

PURPOSE:To track juvenile Atlantic salmon densities.DESCRIPTION:Indices of freshwater production are derived annually from electrofishing surveys in the rivers of Nova Scotia flowing into the Gulf of St. Lawrence. Fixed site sampling for juvenile salmon has been conducted most consistently since the mid-1980s for these rivers. Juvenile salmon abundances at sites, in terms of number of fish per habitat area sampled by age or size group (densities), are obtained using successive removal sampling or catch per unit effort sampling calibrated to densities. Sampling intensities vary among years and among rivers. PARAMETERS COLLECTED:distribution (ecological); species counts (ecological); point (spatial)USE LIMITATION:To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.

The Fish and Wildlife Enforcement Regions dataset is comprised of the polygons representing Fish and Wildlife Enforcement Regions in Alberta. Alberta Public Safety and Emergency Services, Government of Alberta, manages the Fish and Wildlife enforcement services to provide the public and other government departments' information regarding the locations of Fish and Wildlife Enforcement Regions throughout the province.

In 2009, Fisheries and Oceans Canada published the Policy on Managing the Impacts of Fishing on Sensitive Benthic Areas. To support the implementation of this policy, a Canadian Science Advisory Secretariat (CSAS) process was initiated to: assess the distribution of fishing effort in Canada’s Atlantic and Eastern Arctic waters from 2005-2014, evaluate the overlap between fishing effort and Significant Benthic Areas (SiBAs), and identify areas of potential conservation concern. Although Research Document 2018/15 (Koen-Alonso et al. 2018), detailing this work, has not been updated since publication, the methodology outlined within it is still used to generate updated fishing effort layers as new data becomes available. This record illustrates cumulative fishing effort in Canada’s Atlantic and Eastern Arctic waters from 2005-2023, and is based on commercial logbook and vessel monitoring system (VMS) data. Fishing effort has been standardized into percentiles, whereby the top 20th percentile of intensity (cell values ≥20) represent cells containing the most intense fishing activities.
