    This paper describes aspects of the Management Strategy Evaluation (MSE) being developed to evaluate possible management strategies for the Patagonian toothfish fishery in Division 58.5.2. As requested by the Subgroup on Assessment Methods, we elaborate the plausible operating models currently being used for Patagonian toothfish in Division 58.5.2, the types of data and observations of the stock and the fishery being obtained from the region, the parameters that need to be estimated and the types of methods being used to assess yield of toothfish according to the CCAMLR decision rules. We summarise some preliminary results as well as the details of continuing work for assisting the special Subgroup on Assessment Methods workshop to be held prior to the meeting of WG-FSA in 2005. These results will be presented in an updated version of this paper provided to the workshop.
