An aerial survey to assess Steller sea lion (Eumetopias jubatus) pup production in Alaska was conducted by the Alaska Fisheries Science Center (AFSC) from June 24 to July 15, 2009. A secondary objective was to survey adult and juvenile (non-pup) sea lions in southeast Alaska (part of the threatened eastern stock, or distinct population segment, DPS), and in the eastern and central Gulf of Alaska areas (part of the endangered western DPS) to further investigate seasonal movement of sea lions and ascertain its impact on determination of stock trends.
