  1. Overview of NMFS AFSC Field Activities Alaska Fisheries Science Center 7600 Sand Point Way NE Seattle, WA

  2. Auke Bay Laboratory • Longline survey • GOA stock assessments for rockfish, shark, Sablefish. • Ocean Carrying Capacity Program (OCC) • Bering – Aleutian Salmon International Survey (BASIS)

  3. Planned longline survey for 2005 - 2006

  4. Resource Assessment and Conservation Engineering (RACE)Groundfish Assessment Program Bottom trawl surveys to assess abundance of groundfish in the Gulf of Alaska, Aleutian Islands and eastern Bering Sea Research on survey methodology Research on the design and configuration of commercial and research fishing gears Research on factors influencing the life history (maturity) and distribution of groundfish Research on habitat associations of groundfish and responses of fish to habitat disturbance

  5. Planned GAP Research Cruises for 2005 - 2006

  6. Yellowfin sole

  7. RACE Midwater Assessment & Conservation Engineering Echo Integration/Trawl Surveys to assess abundance of pelagic pollock in the Gulf of Alaska and eastern Bering Sea Research on fisheries acoustics and survey methodology Research involving innovative applications of acoustics in fisheries science Research on the design and configuration of commercial and research fishing gears Research on bycatch reduction devices Research on impacts of fishing on habitat

  15. Sea Lion Prey Study Areas Prince William Sound SE Alaska Kodiak Seguam E Aleutians Existing Proposed Existing summer

  16. Pacific Cod Trawl Catch 1999 (Rebecca Reuter, AFSC) • SSL diet data - Pacific Cod is important item in winter • Late winter nutrition critical for females & weaned juveniles ? • Cod spawning aggregations - important seasonal food supply ? • Intense, localized fishery (trawl, pots, & longline) • Look for localized depletion or disturbance

  17. The Bread Line (SW end)

  18. Results 2000 Seguam Pass Inside: Released : 7000 tags Recovered: 20 tags • P=0.03 • (95% CI 0-0.1) Outside: Released: 5300 Recovered : 198 • N=118,000 mt • (27,000-208,000) • N=82,000 mt • (55,000-108,000) • P=0.6 ?? • (95%CI: 0-1)
