(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. |
