The longline survey abundance index increased 9 % from 2017 to 2018 following a 14% increase in 2017 from 2016. The lowest point of the time series was 2015. The fishery catch-rate/abundance index stayed level from 2016 to 2017 and is at the time series low (the 2018 data are not available yet). Spawning biomass is projected to increase rapidly from 2019 to 2022, and then stabilize. Sablefish are managed under Tier 3 of NPFMC harvest rules. Reference points are calculated using recruitments from 1977-2014.
