This report presents new stock assessments for the rock lobster (Jasus paulensis) fishery of the Saint Paul and Amsterdam islands with data up to the last fishing campaign of 2020/21. These new assessments are based on statistical catch at age models using all available data except tagging program data. Stock status trajectories for both stocks start from a period of unsustainable fishing in the 1980s and recovered in the 1990s. The assessment results indicate that exploitable biomass in 2020 is likely to be well above BMSY, biomass status (B/BMSY) are 1.09 (0.86 - 1.50) and 2.12 (1.66 – 2.92) for Saint Paul and Amsterdam stocks respectively, and that fishing mortality is well below FMSY. These estimates are consistent with the results of preliminary assessment from biomass dynamic models. The short-term projection scenarios that were tested show that current catch levels are compatible with the sustainability of the rock lobster stocks.
