dc.description.abstractThe Operating Models (OMs) presented in Brandão and Butterworth (2019) for the toothfish resource in the Prince Edward Islands region are used for initial trials of a Candidate Management Procedure (CMP) which could provide future TAC recommendations for this resource. The performance of a simple CMP control rule based upon recent trends in CPUE is investigated. This CMP is able to secure an increase in the TAC without adversely affecting the status of the resource under most OMs. However, the performance under OM17, which addresses the concern with the poor fit to the trotline CPUE data in the last two years, is not satisfactory. In order to tune this CMP to react satisfactorily under the scenario assumed by OM17 would heavily penalise TACs under the scenarios reflected by the other OMs. A CMP which incorporates other information, to hopefully be able in some sense to better distinguish what the status of the resource is, might perform better under all OMs.en_US
