1. 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

2. Modelling egg and larval transport of Antarctic toothfish (Dissostichus mawsoni) in the East Antarctic region: preliminary result using satellite data

   Abstract:  Using two different surface geostrophic filed data (A-1: without and A-2: with temporal eddy activity) covering 2011-2018, we developed the particle tracking model to investigate egg and larval transport of the Antarctic Toothfish in the East Antarctic region. This paper presents the

3. Patagonian toothfish in the South Indian Ocean outside CCAMLR waters: a preliminary analysis of the SIOFA Patagonian toothfish population

   Abstract:  A descriptive analysis of the Patagonian toothfish (Dissostichus eleginoides) population using data collected from observers onboard  two Spanish fishing vessels, obtained between 2017 and May 2019, in international waters of the South Indian Ocean within the FAO areas 51.7 and 57.4

4. 2019 update of ongoing work on age and growth of Antarctic toothfish (Dissostichus mawsoni) from Divisions 58.4.1 and 58.4.2

   Abstract:  Spanish and Australian scientists are working on the age and growth estimates of Antarctic toothfish within divisions 58.4.1 and 58.4.2 from 2015 and 2017 respectively. During 2019, Korean scientists have joined this colaborative work. Age-length frequencies from the three members are

5. 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

6. Annual report of research fishing operations at Division 58.4.4b in the 2018/19 fishing season

   Abstract:  This paper represents the annual report of the multi-member longline survey on Patagonian toothfish (Dissostichus eleginoides) at Division 58.4.4b in the 2018/19 fishing season by Japan and France. The C2 and Observer data sets were provided by the CCAMLR Secretariat on the 7th August,

7. CASAL model evaluation incorporating the calculation of harvest rate for D. eleginoides at Division 58.4.4b

   Abstract:  In order to achieve the milestone “1.5 Update CASAL model” of the ongoing research plan submitted by Japan and France (WG-SAM19/08), the CASAL models for Dissostichus eleginoides at Division 58.4.4b were revised. Following WG-SAM-2019 suggestions (para 6.76 in the WG-SAM2019 report), we

8. Correlation of sea-surface temperature (SST) with sea-ice concentration (SIC) between Subarea 48.6 and other areas such as Ross Sea, Weddell Sea

   Abstract:  Since the correlation of SST between Subarea 48.6 and Division 58.4.2 was reported in Namba et al. (WG-SAM-17/10), correlations of SIC between Subareas 48.6 and 88.1 (Ross Sea), Weddell Sea and the Sea offPeru were re-analyzed in this paper. There is some correlation of SIC between

9. Effective, cost-limited and easy-to-implement photo-identification from fishing vessels: an alternative to no effort at all

   Abstract:  Photo-identification is a technique that uses photographs of animals to identify individuals through natural markings visible on their body and is central for research on cetaceans. Best gear configuration to conduct photo-identification consists in a SLR camera equipped with a 100-400

10. Possibility of predicting sea-ice concentration (SIC) in research block (RB) 48.6-5 (Southern part of Subarea 48.6) using sea surface temperature (SST) in RB 48.6-2 (Northern part of 48.6)

    Abstract:  It  was  reported  at  WG-SAM-2019  that  the  sea  ice  concentration  (SIC) of RB 48.6-5 corresponded well with the dynamics of monthly sea surface temperature  (SST)  anomaly  in  RB  48.6-5.   However,  in  the  prediction  of SIC  in  RB  48.6-5  using  the  monthly  SST  anomaly,
