This assessment is a partial assessment in accordance with the current assessment schedule. The estimated 2019 total sculpin complex biomass in the GOA is 33,010 t from a random effects model fit to survey data. This represents a small decrease from the last full assessment in 2015. The recommended 2020 and 2021 ABC is 5,199 t based on an FABC=0.16 and the 2020 and 2021 overfishing level is 6,932 t based on an FOFL=0.21. The decrease is due to decreasing sculpin biomass in the 2019 GOA survey relative to the 2017 survey.
