  • Description:
    Arrowtooth flounder biomass estimates in the current model have changed relative to the projection model estimates in 2016. The model projection of spawning biomass for 2018, assuming fishing mortality equal to the recent 5-year average, was 873,789 t, 24% lower than the projected 2018 biomass from the 2016 assessment of 1,154,310 t. The 2018 ABC (estimated in 2017) using F40% was 170,510 t. The 2018 and 2019 ABCs using F40% were lower, 150,945 t and 145,234 t, The projected estimate of total biomass for 2018 was down by 32% from the 2016 assessment of 2,079,029 t, to 1,421,306 t. The 2018 and 2019 OFLs estimated using the projection model were 180,697 t and 173,872 t. The arrowtooth flounder stock in the Gulf of Alaska is not being subjected to overfishing and is not approaching a condition of being overfished.
