Tabular dataset containing age, sex, and length data for Chum, Chinook, and Sockeye salmon. Sex was determined externally using visual clues such as snout shape and size. Length was measured from fork to mid-eye with a measuring board to the closest 5 mm. Strata refers to the potion of the run the fish was sampled during. Strata data is based on the size of the population rather than date since the salmon run does not start on one specific date year by year. Scales were also taken and placed on a gum card for age assessment. One scale was taken for all sampled Chum salmon and three scales were taken for all sampled Chinook salmon.

PURPOSE: This product serves a public facing webpage for the Canadian public to download near real-time data on counts of Atlantic salmon. The data is updated every two weeks where available and is used as an important stakeholder engagement tool. DESCRIPTION: Adult Atlantic salmon returning to specific rivers in the Maritime provinces (New Brunswick and Nova Scotia) are captured and counted at monitoring facilities. Salmon are captured using various methods. Counts of salmon at barrier fences, counting fences, fishways, and at dams usually represent the total run size of fish at that point in the river. Counts at trapnets in estuaries represent partial counts to the river. Counts of Atlantic salmon are presented for two size groups: Salmon: fork length >= 63 cm Grilse: fork length < 63 cm. The map of salmon counting sites identifies the locations of counting facilities throughout the region. Data on salmon and grilse counts are available for each location on the map. A summary table of cumulative data by rivers surveyed can be viewed for salmon and grilse. USE LIMITATION: Please contact the data custodians before attempting to use this information in support of any kind of scientific analyses.

Tabular datasets containing information pertaining to fish caught during trapping effort in the Deshka River between 2019 and 2024 to sample juvenile salmon. These data collected from the field are used to assess effort and were acquired using a Survey123 data acquisition application.

Collection of datasheets (pdf files) containing raw data collected during baited minnow trap study in 2021.

This dataset represents fish sampling and habitat measurements (https://data.kingcounty.gov/Environment-Waste-Management/Habitat-data-for-Juvenile-Pacific-salmonid-habitat/mtrd-zgtr/about_data) from the Snoqualmie and Green rivers in the Puget Sound region of Washington State, USA. Using a cataraft mounted with a boat electrofisher, these data were collected between late winter and late spring from 2016 through 2022. Measurements were of 25-m-long transects along six different edge habitat types in the two rivers. The edge habitats represented in this dataset are ‘armored banks’, ‘biorevetment banks’, ‘unarmored banks’, ‘bars’, ‘backwaters’, and ‘side channels’. These data were collected as part of monitoring of eight habitat restoration or bioengineered bank stabilization projects in the Snoqualmie and Green rivers, along with three more general studies of fish-habitat relationships in the two rivers. These data are analyzed and presented in the journal article “Juvenile Pacific salmonid habitat use in two Puget Sound lowland Rivers”, published in the Transactions of the American Fisheries Society (https://afspubs.onlinelibrary.wiley.com/doi/10.1002/tafs.10457). All data were collected by the King County Water and Land Resources Division, Science and Technical Support Section. Habitat data were collected during the day and include measurements of the width of low-velocity habitat (≤ 0.45m/s) and water depth along each transect. Fish sampling occurred after darkness fell the evening following habitat data collection. Fish data include the number of each species sampled at each transect and the number of seconds each transect was electrofished.

Scales are collected annually from smolt trapping operations in Maine as wellas other sampling opportunities (e.g. marine surveys, fishery sampling etc.). Scale samples are imaged and age, origin, and measurement data are collected as needed for specific growth-related research.

Subadult and smolt behavioral data were compiled by Ali Mokdad from Trevor Pitcher's lab at the University of Windsor, Ontario, Canada. Data are comprised of fish reactions in choice flume video data (attractance/avoidance) collected by Jeremy Kraus at Tunison Lab of Aquatic Science, August 2021 and February 2020 respectively. Atlantic salmon were exposed/not exposed to imprinting chemical (morpholine) through early life stages and later tested based on their treatment to see how individuals react to the presence of exposure chemicals during subsequent life stages. These data show how the adult stage Atlantic salmon of this study ((non exposed (control) and treatment (morpholine exposed)) react to timed exposure of morpholine dilution at the 3+ and 1+ year life stages. Imprinted Atlantic salmon morphometric data were collected Feb 20, 2020 at Tunison Lab. These data represent growth (length (mm) and weight (g)) of experimental Atlantic salmon, just after imprinting flume tests were completed for their life stage/age.
