The data was taken from the Hatchery Release Report on the Alaska Department of Fish and Game website (https://mtalab.adfg.alaska.gov/CWT/reports/hatcheryrelease.aspx) on 04-04-2018. The data file HR002286.csv includes the annual salmon hatchery release data from 1952-2017 in Alaska. This dataset includes the total release count from different release agencies throughout the state. The file lists information about coded wire tag and Alaskan non-coded wire tag groups released since 1968. While there is information about non-Alaskan coded wire tag groups from the data, it is primarily intended for Alaskan Hatchery production release summaries. This dataset was generated by selecting all releases (including non-thermally marked), from all release agencies, species, and rearing codes, from the state of Alaska. The district_region_lut.csv file enables assignment of region for the State of Alaskan Salmon and People (SASAP) project to be assigned based on the district information. Hatchery_releases.csv is generated from HR002286.csv and district_region_lut.csv by the Rmd, which adds the SASAP region and district information, converts some codes (such as species codes) to more readable names, and makes some summary plots.
