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.

Tabular dataset containing age, sex, and length biometric data for all whitefish species detected and recorded at the Andreafsky weir for 2010-2013 and 2015. Data was compiled from in-season data sheets. Sex was identified visually and length was measured using a measuring board to the nearest 1/2 mm. Total weight in grams was taken for every sampled individual. if the specimen was identified as a female, egg weight in grams was recorded and relative egg weight as a percentage was calculated. NA refers to missing data.

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

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.

This is a tabular data set containing age, sex, and length measurements of Inconnu sampled from the Yukon River and tributaries in Alaska between 1990 and 2018.

Hourly counts of all fish species observed at the Andreafsky Weir. Data are derived from weir video feed for available years 2015-2023. Counts were done hour by hour for 24 hours a day unless maintenance was required or conditions disrupted the video feed. NA delineates times in which the video feed was not active while 0 delineates that no fish were counted for that hour. All species have been standardized and counted every year since the implementation of the video feed.

Tabular dataset containing the fork length of captured salmonids as well as the sampling reach wherein they were captured and date when they were captured during a baited minnow trap study in Campbell Creek Alaska in 2021.
