| Summary: | This dataset contains annual commercial salmon harvest information from fisheries in Alaska from 1975-2016, provided by the Alaska Department of Fish and Game (ADF&G). Included are the number of fish caught by salmon species, the number of people and permits issued, and the number of fish processors used, and vessels used. Three files are included with differing geographic resolutions, which from coarse to fine consist of spatial resolutions: commercial fishing area, commercial fishing district, and commercial fishing subdistrict. All files are annual with the exception of one, which organizes harvest data by statistical week. This time scale facilitates aggregated catch comparisons between years. Note that some rows within each file are marked as confidential when the number of either permits, people, or processors is under 3. Finer spatial or temporal resolution datasets result in more confidential rows. These data are provided to facilitate understanding of commercial harvest of salmon in Alaska, and how this harvest changes both over time and space. Data shown here were modified slightly from what was provided by (ADF&G) by replacing internal species and gear codes with more readily understandable species names and gear descriptions.
