(2001 Stock Asessment Summary: part 2)
The values presented below reflect information found in the SAFE documents developed by the NPFMC Plan Teams for groundfish fisheries in the Gulf of Alaska and Bering Sea/Aleutian Islands (Table 2 and 3 below).  It should be noted that the Plan Team ABC and TAC recommendations are reviewed by the NPFMC advisory bodies, and the NPFMC recommends the final TAC.  Thus, the values presented below may differ from the final NPFMC recommendations.  For information on final groundfish specifications, please consult the NPFMC’s web page at http://www.fakr.noaa.gov/npfmc.

Table 2. Summary of stock abundance (biomass), overfishing level (OFL), acceptable biological catch (ABC), the fishing mortality rate corresponding to OFL (FOFL), and the fishing mortality rate corresponding to ABC (FABC) for the eastern Bering Sea (EBS), Aleutian Islands (AI), and Bogoslof district as projected for 2002. Biomass corresponds to projected January 2002 abundance for the age+ range reported in the summary section. Biomass, OFL, and ABC are in metric tons (t). Fs are reported to three significant digits.
