Data provided by National Oceanic and Atmospheric Administration
This data layer represents the 12 uniquely identified stocks of harbor seals found in Alaskan waters. Stocks were identified by NMFS and their co-management partners, the Alaska Native Harbor Seal Commission, in 2010 based largely on genetic structure. Given the genetic samples were not obtained continuously throughout the range, a total evidence approach was used to consider additional factors such as population trends, observed harbor seal movements, and traditional Alaska Native use areas in the final designation of stock boundaries. The 12 stocks of harbor seals currently identified in Alaska are 1) the Aleutian Islands, 2) the Pribilof Islands, 3) Bristol Bay, 4) North Kodiak Island, 5) South Kodiak Island, 6) Prince William Sound, 7) Cook Inlet/Shelikof Strait, 8) Glacier Bay/Icy Strait, 9) Lynn Canal/Stephens Passage, 10) Sitka/Chatham Strait, 11) Dixon/Cape Decision and 12) Clarence Strait.
