Electrofishing Data from Nova Scotian Rivers (SFA 18A, 18B)

Electrofishing Data from Nova Scotian Rivers (SFA 18A, 18B) 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: Please contact the data custodians before attempting to use this information in support of any kind of scientific analyses. 2024-06-17 Fisheries and Oceans Canada DFO.GLFCSA-CASGLF.MPO@dfo-mpo.gc.ca Nature and EnvironmentScience and TechnologySalmons/TroutsRIVERS/STREAMELECTROFISHINGSalmo salarFishGulf of St. Lawrence Electrofishing Juvenile Densities by SiteCSV https://api-proxy.edh.azure.cloud.dfo-mpo.gc.ca/catalogue/records/73c3293c-72bc-53aa-dc3d-c21143197490/attachments/Juvenile_densities_by_site.csv Electrofishing Raw Species DataCSV https://api-proxy.edh.azure.cloud.dfo-mpo.gc.ca/catalogue/records/73c3293c-72bc-53aa-dc3d-c21143197490/attachments/Raw_species_data.csv Data Dictionary - Juvenile Densities by SiteCSV https://api-proxy.edh.azure.cloud.dfo-mpo.gc.ca/catalogue/records/73c3293c-72bc-53aa-dc3d-c21143197490/attachments/data_dictionary_juvenile_densities_by_site.csv Data Dictionary - Raw Species DataCSV https://api-proxy.edh.azure.cloud.dfo-mpo.gc.ca/catalogue/records/73c3293c-72bc-53aa-dc3d-c21143197490/attachments/data_dictionary_raw_species_data.csv Electrofishing Juvenile Densities by SiteESRI REST https://gisp.dfo-mpo.gc.ca/arcgis/rest/services/FGP/Electrofishing_Data_Nova_Scotian_Rivers/Mapserver Electrofishing Juvenile Densities by SitesESRI REST https://gisp.dfo-mpo.gc.ca/arcgis/rest/services/FGP/Electrofishing_Data_Nova_Scotian_Rivers/Mapserver
