• Description:
  The estimated ABC and OFL values for 2018 and 2019 in this update are slightly lower than the values for 2017 and 2018 produced in the 2016 assessment because the biomass estimate of sculpins in the Bering Sea shelf were lower than the 2016 estimate (164,449 t vs. 180,729 t). The other two surveys (Aleutian Islands and Bering Sea slope) that provide data for this assessment have not changed. OFL and ABC declined slightly from the 2018 estimated presented in the 2016 stock assessment, and the FOFL changed slightly because the proportion of the six most common species shifted slightly since the 2016 assessment.
