    Based on a recommendation by WG-FSA-2021 we present an update on stock parameters, including recruitment indices from the random stratified trawl survey, and Chapman estimates of vulnerable biomass from tag-recapture data for the Patagonian toothfish (Dissostichus eleginoides) fishery in CCAMLR Division 58.5.2. These data indicate that the stock trajectory is consistent with that predicted by the 2021 stock assessment model. Recent high survey biomass and strong cohorts of young fish in the survey catch composition also indicate the potential for a recruitment pulse.
