Assessment of Patagonian toothfish (Dissostichus eleginoides) in Subarea 48.4

This paper describes an updated CASAL based assessment of Patagonian toothfish (D. eleginoides) in Subarea 48.4. The assessment data are updated with the observations for the 2017/18 season and the data weighting method revised to be consistent with those applied in other CCAMLR assessment model fits. Stock projections indicate that the stock was at 67% of B₀ in 2018/19 and that a yield of 27 tonnes in 2019/20 and 2020/21 is consistent with the application of the CCAMLR harvest control rule.
