Federal Register / Vol. 86, No. 32 / Friday, February 19, 2021 / Rules and Regulations specifications 85 FR 78076, December 3, 2020 for Pacific cod, arrowtooth flounder, flathead sole, Pacific ocean perch, northern rockfish, dusky rockfish, rougheye/blackspotted rockfish, and demersal shelf rockfish.
The final 2021 ABCs are lower than the proposed 2021 ABCs for pollock, sablefish, shallow-water flatfish, thornyhead rockfish, and sharks.
The final 2022 ABCs are higher than the proposed 2022 ABCs for Pacific cod, sablefish, shallow-water flatfish, flathead sole, Pacific ocean perch, northern rockfish, dusky rockfish, rougheye/blackspotted rockfish, and demersal shelf rockfish. The final 2022
ABCs are lower than the proposed 2022
ABCs for pollock, arrowtooth flounder, thornyhead rockfish, and sharks. For the remaining target species, the Council recommended the final 2021 and 2022
ABCs that are the same as the proposed 2021 and 2022 ABCs.
Additional information explaining the changes between the proposed and final ABCs is included in the final 2020
SAFE report, which was not completed and available when the Council made its proposed ABC and TAC
recommendations in October 2020. At that time, the most recent stock assessment information was contained in the final 2019 SAFE report. The final 2020 SAFE report contains the best and most recent scientific information on the condition of the groundfish stocks, as previously discussed in this
preamble, and is available for review see ADDRESSES. The Council considered the 2020 SAFE report in December 2020 when it made recommendations for the final 2021 and 2022 harvest specifications. In the GOA, the total final 2021 TAC amount is 407,975 mt, an increase of 1.3 percent from the total proposed 2021 TAC
amount of 402,783 mt. The total final 2022 TAC amount is 409,039 mt, an increase of 1.6 percent from the total proposed 2022 TAC amount of 402,783
mt. Table 1a summarizes the difference between the proposed and final TACs.
Annual stock assessments incorporate a variety of new or revised inputs, such as survey data or catch information, as well as changes to the statistical models used to estimate a species biomass and population trend. Changes to biomass and ABC estimates are primarily based on fishery catch updates to species assessment models. Some species, such as pollock and sablefish, have additional surveys conducted on an annual basis, which resulted in additional data being available for the 2020 assessments for these stocks.
The changes from the proposed 2021
TACs to the final 2021 TACs are within a range of plus 169 percent or minus 60
percent, and the changes from the proposed 2022 TACs to the final 2022
TACs are within a range of plus 335
percent or minus 60 percent. Based on changes in the estimates of overall biomass in the stock assessment for
10187

2021 and 2022, as compared to the estimates previously made for 2020 and 2021, the species or species group with the greatest TAC percentage increases are Pacific cod, Pacific ocean perch, northern rockfish, and dusky rockfish.
Based on changes in the estimates of biomass, the species or species group with the greatest decreases in TACs are sablefish, other rockfish, and sharks, as well as pollock 2022 TAC. The 2021
sablefish TAC decreases by 19 percent, but increases in 2022 by 13 percent, compared to estimates previously made for 2020 and 2021. For all other species and species groups, changes from the proposed 2021 TACs to the final 2021
TACs and changes from the proposed 2022 TACs to the final 2022 TACs are less than a 10 percent change either increase or decrease. These TAC
changes correspond to associated changes in the ABCs and TACs, as recommended by the SSC, AP, and Council.
Detailed information providing the basis for the changes described above is contained in the final 2020 SAFE report.
The final TACs are based on the best scientific information available, including biological and socioeconomic information. These TACs are specified in compliance with the harvest strategy described in the proposed and final rules for the 2021 and 2022 harvest specifications.
