1. A preliminary model-based approach for estimating natural mortality of Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea Region

   Abstract:  Natural mortality (M) is a key parameter in fisheries stock assessments, relating directly to the productivity of a stock, stock status, and estimated precautionary yields. In the Ross Sea region stock assessment for Antarctic toothfish (Dissostichus mawsoni), M is assumed to be 0.13 y-1

2. Continuation of multi-Member research on the Dissostichus mawsoni exploratory fishery in East Antarctica (Divisions 58.4.1 and 58.4.2) from 2018/19 to 2021/22

   Abstract:  Exploratory fishing for toothfish (Dissostichus mawsoni) in East Antarctica (Divisions 58.4.1 and 58.4.2) began in 2003. Robust stock assessments and catch limits according to CCAMLR decision rules remain to be determined for these Divisions. WG-FSA-16/29 outlined the first multi-member

3. Tag linking – revised algorithm (2019)

   Abstract:  The CCAMLR Tagging Programme is a key part of CCAMLR’s management of toothfish fisheries and linking the details of recaptured fish to that of tagged fish is a key element of the programme. The CCAMLR Secretariat has developed a new tag linking approach that is designed to provide

4. 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

6. 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

7. 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

8. 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

9. 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

10. 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
