Assessment of Patagonian Toothfish (Dissostichus eleginoides) in Subarea 48.4

This paper describes an update of the assessment of Patagonian toothfish (D. eleginoides) in Subarea 48.4. The assessment data are updated with the observations for the 2021 and 2022 seasons. Projections indicate that the stock was at 59.5% of B₀ in 2023 and that a yield of 19 tonnes in 2024 and 2025 is consistent with the application of the CCAMLR Decision Rule.

Based on this assessment, we propose two recommendations from Working Group FSA to the Scientific Committee:

1. that the Casal2 stock assessment replace the CASAL stock assessment as the basis for providing catch advice for this stock, and the migration to Casal2 be regarded as complete,
2. that the catch limit for D. eleginoides in Subarea 48.3 should be set at 19 tonnes for 2023/24 and 2024/25.
