This dataset compiles salmon escapement data from Alaska Department of Fish and Game reports and salmon harvest data from commercial, personal use, sport fish, and subsistence sectors to generate an estimate of total salmon abundance in each of the regions defined by the State of Alaska's Salmon and People Project (SASAP). This dataset was assembled to enable a broad view of the salmon resource, whether biological (escapement) or economic/cultural (harvest), across regions. With that intent in mind, a fish is counted within a region if it escaped a fishery and was counted in a river that is contained within that region, or if it was caught in a fishery that is within the region. For commercial fisheries, each commercial fishing district was assigned to a region based on the location of the commercial fishing district relative to the bounding watersheds of the region. No effort was made to determine the region of origin for any commercially caught fish - thus for some regions, fish caught in one region may have been headed to spawn in another. This is especially true of Alaska Peninsula and Aleutian Islands commercial fishing areas, which are well known for having large amounts of Bristol Bay bound fish. Note that some regions have missing escapement data during some years. This dataset includes an R Markdown file which processes the original data and creates figures, the rendered html file generated from running the R Markdown file which includes many figures and data explanation, and several standalone versions of those figures.
