1. Supervised and unsupervised (RapidKrill) estimates of krill density from DY098

   Abstract:  We compare supervised, using the interactive software Echoview™, and unsupervised, using python,  processing  of acoustic  data  collected  during  the  UK  cruise  DY098.  The  same  data processing procedures are applied in both methods, and we show that the unsupervised method comes

2. Preliminary biomass estimation of Antarctic krill based on the swarm-based method for CCAMLR Division 58.4.1 in 2018/19 using data obtained by Japanese survey vessel Kaiyo-maru

   Abstract:  Biomass (B 0) of Antarctic krill for CCAMLR Division 58.4.1 in 2018/19 was preliminarily estimated as 4.349 million ton (CV=54.8 %) based on the swam based method using data obtained by Kaiyo-maru. The point estimate was comparable with the estimate in 1996 by BROKE (4.83 million ton

3. Stock connectivity of Antarctic toothfish

   Abstract:  For this study, Antarctic toothfish samples were collected from CCAMLR Subareas 48.2, 48.4, 48.6, 88.1, 88.2 and 88.3, Divisions 58.4.1, 58.4.2 and 58.5.2, and the SPRFMO area north of Subarea 88.1. Using approximately equal sample numbers spatially across CCAMLR Areas, DNA from 761

4. Movements of tagged Antarctic toothfish (Dissostichus mawsoni) in Subarea 48.6 in relation to stock structure hypotheses

   Abstract:  We examined movements of tagged Antarctic toothfish (Dissostichus mawsoni) for subarea 48.6 in relation to life history hypotheses. Most of long-distance movements occurred in westward direction along continental shelf, which may be consistent with the single Atlantic population

5. Report on fishing effort and seabird interactions during the season extension trials in the longline fishery for Patagonian toothfish (Dissostichus eleginoides) in Statistical Division 58.5.2

   Abstract:  Minimising seabird interactions with longline operations is a key objective of the management of fisheries in CCAMLR (see e.g. Conservation Measure CM 25-02 and 41-08). Longline fishing in the fishery for Patagonian toothfish (Dissostichus eleginoides) in Statistical Division 58.5.2

6. The CCAMLR Taxon Data Project

   Abstract:  CCAMLR hosts a list of taxa based on the  Aquatic Sciences and Fisheries Information System (ASFIS) List of Species for Fishery Statistics Purposes published by the FAO.The species names used in CCAMLR need to be up to date with current classification and phylogenies. The World Register

7. Preliminary assessment of genetic diversity in bycatch-caught darkbelly skate (Bathyraja meridionalis) from South Georgia

   Abstract:  Reliable species identification and population assessments of skates are crucial for the sustainable management of their vulnerable stocks. However, species identification is a major challenge in skate studies due to convergent morphology within and between genera. In this study, we

8. Progress report on collaborative research for otolith chemistry of Antarctic toothfish Dissostichus mawsoni in the Southern Ocean

   Abstract:  Otolith chemical analysis is one of important and useful approaches to reveal the stock structure and connectivity of Dissostichus mawsoni in the Southern Ocean. Recalling the suggestion from WG-FSA 2018 about the international collaboration on otolith microchemistry of D. mawsoi, this

10. Molecular analysis of stomach contents from Antarctic toothfish (Dissostichus mawsoni) collected from Area 58 and 88 from 2016 to 2018

    Abstract:  Antarctic toothfish, Dissostichus mawsoni is the ecologically important Nototheniidae, which is native to the Southern Ocean. Although it plays an important role in the Antarctic ecosystem, the ecology of D. mawsoni is still fragmental mainly due to the limited accessibility for the
