In Division 58.4.3a, since 2012, research fishing has been conducted in the research block by three vessels using longline: “Shinsei Maru No. 3” (Japan), “Saint André” (France) and “Mascareignes III” (France). The first Franco-Japanese exploratory longline fishery research plan for Dissostichus spp. in Division 58.4.3a (WG-FSA-16/55) was presented to WG-FSA-16, which included research objectives, methods and milestones in accordance with Conservation Measure 41-06 and associated measures. In October 2017, the Scientific Committee agreed that the research plan is appropriate to achieve its objectives (SC-CAMLR-XXXVI, para. 3.121). France and Japan commonly notifies their intention to continue their exploratory fisheries in Division 58.4.3a over the coming years in order to contribute to the tagging program and to achieve a robust stock assessment. We present here a proposal for the continuation of the research plan as set out in WG-FSA-17/55, and taking into account the Scientific Committee’s recommendations.
