    Abstract

    WG-FSA-19 recommended an update on stock parameters, including recruitment indices from the trawl survey, and age-frequency data and tag-recapture data from the fishery be presented to WG-FSA-20 to evaluate whether recruitment and the stock trajectory were consistent with those estimated by the stock assessments for Patagonian toothfish (Dissostichus eleginoides) fishery in CCAMLR Division 58.5.2.

    Here, we present an update on stock parameters, including recruitment indices from the trawl survey, and age-frequency data and tag-recapture data from the fishery. These data indicate that the stock trajectory is consistent with that predicted by the 2019 stock assessment model. Increases in the survey biomass and young fish in the survey catch composition also indicate the potential for a recruitment pulse in recent years.
