^ Since SSB in 2020 is between 2 × Bpa = 920 000 tonnes and 3 × Bpa = 1 380 000 tonnes, F = 0.4 × (1+0.5 × (1227-920)/460) = 0.533 is used in the 3-year prediction, giving catches of 761 080, 674 767, and 633 166 tonnes in 2020, 2021, and 2022, respectively. The average catch over the 3-year period is thus 689 672 tonnes, which corresponds to an F of 0.47 in 2020.
