Request Meeting Document Document Number: WG-SAM-2022/23 Author(s): C. Darby and T. Earl Submitted By: Ms Georgia Robson (United Kingdom) Approved By: Dr Chris Darby Agenda Item(s) WG-SAM-2022 - 3.3 - Stock assessment for data-limited toothfish fisheries Abstract Data limited analysis is applied to tagging returns to determine estimates of exploitation rates (fishing mortality) on the Patagonian toothfish (Dissostichus eleginoides) stock in Subarea 48.3. The results show that the tagging data collected from the fishery can be analysed in a way that is consistent with the simple assumptions of catch curve analysis, to provide data limited estimates that are consistent in their scale with the full CASAL assessment model outputs.
