| Summary: | The Shark SAFE chapter is now split into two chapters; one chapter for the Bering Sea/Aleutian Islands (BSAI), and a separate chapter for the Gulf of Alaska (GOA). This is the GOA chapter. Input Data Incidental catch for sharks by species in the GOA was updated for 2003- 2006 with estimates provided by the NMFS Alaska Regional Office (AKRO- as of Oct 22, 2006). Previous incidental catch estimates were provided by NMFS AKRO for 2003 – 2005 and by Sarah Gaichas from her pseudo-blend estimates in two time series: one for the years 1990 – 1998, and the other for the years 1997-2001. Sarah’s pseudo-blend estimates were updated here for 2002. GOA bottom trawl survey biomass data was updated for 2005. Previous trawl survey data were available from NMFS AFSC bottom trawl surveys conducted triennially and biannually in the GOA (1984 – 2003).
