This paper presents an update of the metrics of capacity and capacity utilisation presented in WG-SAM-14/19 and WG-FSA-15/09 in order to monitor trends in capacity in exploratory toothfish fisheries in Subareas 88.1 and 88.2. The updated metrics show the same pattern as in previous updates and do not indicate an excess of capacity in the fishery.  Interpretation of data for 2018 should be made in the context of changes in the area of operation and the application of fishery closures in the exploratory fishery in Subarea 88.1.
