This paper provides details of SISO observer deployments during the 2019 season (based on data received by the Secretariat up to 18 September 2019). Developments in the Scheme of International Scientific Observation Programme are discussed, and results presented from the vessel tagging pro-forma survey conducted on vessels participating in exploratory fisheries.

La pêche à la légine australe (Dissostichus eleginoides) est pratiquée autour de la Géorgie du Sud depuis plus de 40 ans, dont 25 dans le cadre de la CCAMLR.

Ce document examine le déclin à long terme de la structure de taille de la légine australe (Dissostichus eleginoides) observé dans les captures à la palangre effectuées dans le secteur de la Géorgie du Sud (zone 48.3 de la FAO). Nous observons que depuis le début des années 2000 jusqu'à aujourd'hui, la pêche à la palangre dans le secteur de la Géorgie du Sud vise des juvéniles de poissons de moins de 100 cm de longueur. Il est ici question de l'utilisation non-rationnelle du stock de légine australe dans la sous-zone 48.3.

Russian Federation is going to continue investigation for toothfish in Ross Sea. This paper presents the   research program in the frame of the Research and Monitoring Plan for RSRMOR. 

The research program shall be conducted in the Special Research Zone during 2019 - 2021 or the first reference period for existence of the RSRMPA. This program provides possibility for collaborative investigations in the Special Research Zone by Russian vessels and vessel from other CCAMLR members.

A collaborative research program has been undertaken by Japan and South Africa since 2013 to enhance data collection and analysis in the subarea 48.6. From the last season (2018/19) Spain has joined the proposal in order to contribute to the data acquisition and to speed up the integrated assessments of the Antarctic toothfish (Dissostichus mawsoni) stock in this subarea (FSA-18/34).

The continuation of the three-member research proposal for 2019/20 season is presented to ensure continuity of previous research activities. Data and investigations about the population structure and various demographic parameters of D. mawsoni using trotline (JPN and ZAF) and Spanish longline (ESP) gears, established tagging techniques, pop-up tags and genetic analysis will provide the basis for the development of spatial population models and assessments in support of management advice. An Integrated Stock Assessment (ISA) of this species is expected to be done by the end of the 2020/21 season.

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 and 2019  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.

This paper presents catches of target species from directed fishing on toothfish, icefish and krill in the Convention Area in 2017/18 and 2018/19, and catches taken during research activities pursuant to CM 24-01, paragraph 3. Monthly catch totals for 2018/19, based on data reported to 13 September 2019, are presented with dates of closures of fisheries implemented by the Secretariat.

This paper summarises data collected by Scheme of International Scientific Observation observers and vessels, of incidental interactions between fishing vessels, seabirds and marine mammals during fishing activities undertaken during the 2019 season. A short report is also detailed on a large seal morality event which occurred at the end of the 2018 season. Incidental mortality numbers for longline fisheries in which seabird mortalities have been reported are presented with the data from observers and vessel supplied data. Based on data received up to 8 October 2019, the extrapolated total number of birds killed is 103.

In 2016 the Commission adopted Conservation Measure (CM) 91-05, establishing the Ross Sea region Marine Protected Area (RSRMPA). Annex B of this CM specifies the RSRMPA specific objectives and the Management Plan. In addition, Annex C specifies the Priority elements for Scientific Research and Monitoring, including research and monitoring priorities, and research and monitoring questions that should be addressed.

We recall the objectives of the RSRMPA and the research questions for research and monitoring for the RSRMPA. This paper updates the research and monitoring activities for New Zealand and Italy, as encouraged by CM 91-05 paragraph 16(i)–(ii), noting that other Members are also undertaking relevant research.

New Zealand and Italy recommend that Members continue to share data and research outcomes relevant to the objectives of the RSRMPA.
