Age, sex, and length of chum salmon and chinook salmon sampled at the Gisasa weir between 1995 and 2023
Tabular dataset containing all available age, sex, and length information of Chum salmon and Chinook salmon sampled at the Gisasa Weir by the U.S. Fish and Wildlife Service between 1995 and 2023. Raw data were collected on physical datasheets which are stored at the Northern Alaska Fish and Wildlife Conservation Office, Fairbanks with Jeremy Carlson. Raw data were then manually transcribed to Microsoft workbooks. 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 aging. One scale was taken for all sampled Chum salmon and 3 scales were taken for all sampled Chinook salmon. NA refers to missing data.
