Review of activities in monitoring marine debris in the CAMLR Convention Area
Abstract: In 2012 data on beach surveys, debris associated with seabird colonies, marine mammal entanglements and hydrocarbon soilings were received from South Africa, the United Kingdom, and Uruguay. Non-fishing items such as plastics, packaging materials and wood remain the most common type of

Population assessment of Antarctic toothfish in Subarea 48.4 using tag-recapture method
Abstract: The stock of Antarctic toothfish in the CCAMLR subarea 48.4 was estimated using as the Petersen method as 640 tonnes. Application of the harvest rate used for D. eleginoides in Subarea 48.3 (γ = 0.038) gives yields of 24 t for the Antarctic toothfish in the region vs. previous

Deployment and recovery of an archival tag on an Antarctic toothfish in the Ross Sea
Abstract: Data from electronic archival tags are often used to characterise movement and migration patterns in fishes. Understanding these movement patterns is one of the key information needs for the assessment and management of Antarctic toothfish. We deployed 4 pop-off satellite archival tags

Modelling the circumpolar distribution of Antarctic toothfish (Dissostichus mawsoni) habitat suitability using correlative species distribution modelling methods
Abstract: Understanding and predicting the distribution of Antarctic toothfish (Dissostichus mawsoni) habitat suitability at different spatial and temporal scales can make an important contribution to CCAMLR’s management of this species. In this paper the use of Maxent models with fishery catch

Cetaceans as indicators of historical and current changes in the East Antarctica ecosystem
Abstract: Changes in the Antarctic ecosystem have been triggered by anthropogenic and natural factors. This paper reviews the scientific information of whales that could be indicative of changes in the East Antarctica ecosystem in the context of two hypotheses, the ‘krill surplus’ hypothesis in

Length-weight relationships of six fish species associated with krill fishery in the Atlantic sector of the Southern Ocean
Abstract: Length-weight relationships (LWRs) of six fish species in the Southern Ocean, which commonly associated with Antarctic krill fishery, were determined. Samples were collected with Chinese krill trawler (codend mesh size 2 cm) in the Atlantic sector of the Southern Ocean from January to

Progress update on Antarctic toothfish inter-connectivity project
Abstract: Here we provide a progress update on the Antarctic toothfish genetic connectivity project (WS-DmPH-18/08). A total of 4237 tissue samples have been made available for this project from nine CCAMLR members with the vast majority of these collected during the 2017/18 season. Of the planned

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
