^ Number of participants estimates are based on state and federal fisheries permit data.  The estimated number of participants is expressed in terms of the number of active participants in the fishery, when possible.  If this information is not available, the estimated number of vessels or persons licensed for a particular fishery is provided.  If no recent information is available on the number of participants, then the number from the most recent LOF is used.  NMFS acknowledges that, in some cases, these estimations may be inflating actual effort.  

*Observer coverage levels include the latest information reported in the most current final Stock Assessment Report (SAR)

1 Indicates the stock or species is driving the classification of the fishery 

Note: Current classification based on final LOF, no proposed changes are reflected in this table.

Basis for Current Classification

Mortality or serious injury of either Gulf of Alaska (GOA), Bering Sea (BS), or Aleutian Islands (AI) transient killer whale stock or the overlapping North Pacific Alaska resident killer whale stock exceeds 1%, but does not exceed 50% of either stock’s PBR.  One killer whale serious injury/mortality occurred in this fishery between 2007 and 2011, but as these killer whale stocks overlap in time and area, it was not determined from which stock the take occurred.  However, the one serious injury mortality places this fishery in Category II for either stock.

Timeline of Changes

2015
  • Estimated number of participants updated from 10 to 17.
2013
  • Elevated to Category II based on observed mortality of killer whale (GOA, AI, BS transient) that occurred between 2007 and 2010. The mean annual mortality of killer whales (GOA, AI, BS transient) across all fisheries is 1.25 or 22.7% of PBR (5.5).  The mean annual mortality caused by this fishery is 0.25 or 4.5% of PBR. This fishery is classified as Category II because the mean annual mortality caused by this fishery falls between 1% and 50% of PBR.
2009
  • Estimated number of participants updated from 9 to 10.
2004
  • In 2004 four large groups of federally managed fisheries in Alaskan waters were separated into 25 fisheries based on geographic location, target species and gear type.  This fishery was included in the larger group of “Bering Sea, Aleutian Islands groundfish trawl” fishery prior to 2004, and in 2004 was broken out as the “Bering Sea, Aleutian Islands rockfish trawl” fishery.  It was placed in Category III at that time as no specific information on marine mammal takes were attributed to that fishery.
