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

4 Planned longline survey for 2005 - 2006

5 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

6 Planned GAP Research Cruises for 2005 - 2006

7 Yellowfin sole

8 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

17 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
