1. Fisheries research within the Ross Sea region Marine Protected Area

   Abstract:  The introduction of the Ross Sea region Marine Protected Area has elevated the need for research (including fisheries research) to inform the Research and Monitoring Plan and to evaluate the effectiveness of the Marine Protected Area. All research should be based on a robust experimental

2. Revised proposal for the ongoing research plan on Patagonian toothfish (Dissostichus eleginoides) in Division 58.4.4b (2016/17–2020/21)

   Abstract:  Division 58.4.4b has been a closed area since 2002 (CM 32-02) and scientific research has been conducted with a research plan submitted under CM 24-01 since 2008 by Japan. France joined this research plan in 2015 and a joint proposal was submitted for the first time in 2016 (WG-SAM-16/06

3. Statistical modelling of by-catch patterns: a preliminary case study using research fisheries in Subarea 48.6

   Abstract:  We report a preliminary result of statistical modeling of grenadier bycatch pattern by bottom longline research fisheries in CCAMLR Subarea 48.6, using generalized linear mixed models with zero-inflation. The result contains several issues including the failure of estimation in

4. Progress report on the joint research for Dissostichus spp. in Subarea 88.3 by the Republic of Korea and New Zealand in 2018/19

   Abstract:  The scientific survey was conducted by the Greenstar (KOR) in the research block 883_1–883_P9. Due to extreme ice conditions covering the southern part of 88.3, Janas (NZL) was not able to conduct its part of the survey. The total catch of D. mawsoni was 63,840 kg comprising 2,526

5. Patagonian toothfish tagging study plan in the southwest Atlantic (FAO Area 41)

   Abstract:  We propose to conduct an exploratory satellite tagging campaign of Patagonian toothfish (Dissostichus eleginoides) in the Southwest Atlantic Ocean (FAO Area 41). Existing data on this species is extremely rare and incomplete in both study duration and geographic coverage. This proposal

6. Chemical marking protocols for Antarctic starry skate age validation

   Abstract:  A field study is planned to validate the thorn ageing method for Antarctic starry skate (Amblyraja georgiana). This study is a fast, simple ‘add-on’ that will complement the aims of the skate tagging programme. The antibiotic terramycin (oxytetracycline hydrochloride, OTC) will be

7. Planned updates for the integrated stock assessment for the Heard Island and McDonald Islands Patagonian toothfish (Dissostichus eleginoides) fishery in Division 58.5.2

   Abstract:  This paper describes some of the planned updates to the 2019 integrated stock assessment for the Heard Island and McDonald Islands Patagonian toothfish (Dissostichus eleginoide s) fishery in Division 58.5.2. These updates will include, inter alia, the estimation and inclusion of fishing

8. Report on joint exploratory fishing in Divisions 58.4.1 and 58.4.2 between the 2011/12 and 2018/19 fishing seasons

   Abstract:  Robust stock assessments and catch limits for Dissostichus mawsoni according to CCAMLR decision rules remain to be determined for Divisions 58.4.1 and 58.4.2, and precautionary management arrangements are in place as set out in Conservation Measures 41-11 and 41-05.

9. Exploration of CPUE standardisation variances in the Ross Sea (Subareas 88.1 and 88.2A South of 70°s) Antarctic toothfish (Dissostichus mawsoni) exploratory longline fishery

   Abstract:  Catch rates or catch per unit of effort (CPUE) are used for data-poor exploratory fisheries without integrated assessments in the CPUE by seabed area method to estimate stock biomass in the interim of collecting sufficient tag recaptures. Here, we address the two questions: (1) which

10. Proposed continuation of a multi-Member longline survey on Antarctic toothfish (Dissostichus mawsoni) in Statistical Subarea 48.6 in 2019/20 by Japan, South Africa and Spain

    Abstract:  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
