The Reference case assessment of the Prince Edward Islands (PEI) toothfish (Dissostichus eleginoides) resource reported by Brandão and Butterworth (2019) is updated to take the further data now available for 2019 and 2020 into account. The differences in the results between the Reference case model of 2019 and that of 2021 are minimal. With these further two years of data available, the results show a very slightly better status for the resource in 2018, but also a slight decline in abundance over the last two years (which nevertheless still sees the resource well above 𝐵𝑀𝑆𝑌).
