Assessment of the blackspotted and rougheye rockfish stock complex in the Bering Sea and Aleutian Islands
Filetype[PDF-61.02 KB]

  • Alternative Title:
    BSAI Chapter 14
  • Description:
    In 2005, BSAI rockfish were moved to a biennial assessment schedule with full assessments in even years to coincide with the frequency of trawl surveys in the Aleutian Islands (AI) and the eastern Bering Sea (EBS) slope. In 2017, the scheduled frequency for some stock assessments was changed in response to the National Stock Assessment Prioritization effort, with Bering Sea/Aleutian Islands (BSAI) blackspotted/rougheye rockfish maintaining its existing schedule. The 2016 full assessment can be found at http://www.afsc.noaa.gov/REFM/docs/2016/BSAIrougheye.pdf. In years without a scheduled Aleutian Island survey, a “partial assessment” is produced by revising the recent catch data and re-running the projection model using the results from the previous full assessment as a starting point. Therefore, this update does not incorporate any changes to the 2016 assessment methodology, but does update the catch estimates for 2016-2018 and provides an estimated catch for 2019. The partial assessment also includes estimates of catch/biomass (i.e., exploitation rates), using estimated total biomass.
