2. Proposal for a winter longline survey of Antarctic toothfish in the northern region of Subareas 88.1 and 88.2

   Abstract:  We propose to test three hypotheses to describe the reproductive ecology of Antarctic toothfish (Dissostichus mawsoni): 1) Antarctic toothfish eggs are buoyant and accumulate under sea ice. If true, this would retain eggs near the spawning locations under the vast sea ice extent and once

3. Proposal to continue the time series of research surveys to monitor abundance of Antarctic toothfish in the southern Ross Sea, 2018–2022

   Abstract:  This paper proposes to continue the Ross Sea shelf toothfish survey for the next five years, 2018–2022. The first objective of the survey is to monitor toothfish recruitment in the southern Ross Sea (core strata). This is a continuation of the yearly time series of research surveys of

4. Revised joint research proposal for Dissostichus spp. in Subarea 88.3 by Korea and New Zealand

   Abstract:  A research plan for this subarea was commenced by Korea in 2016 and a revised collaborative proposal was submitted to WG-FSA-17 by Korea and New Zealand. This joint research proposal was for an additional 3 years covering the period 2018, 2019 and 2020. It was designed to build on Korea

5. Spatial distribution and population structure of juvenile Antarctic toothfish (Dissostichus mawsoni) in the South Shetland Islands (Subarea 48.1)

   Abstract:  In the present study we provide new insights on the spatial distribution and population structure of juvenile D. mawsoni caught during bottom trawl survey on the shelves around the South Shetland Islands (CCAMLR Subarea 48.1). Fish samples were collected during five summer cruises

6. A comparative morphometric analysis of sagittal otoliths of three icefishes (Channichthyidae) in Antarctic waters

   Abstract:  In the present study a comparative morphometric analysis of sagittal otoliths was performed in three Channichthyids (Pseudochaenichthys georgianus, Chaenocephalus aceratus and Chaenocephalus gunnari) collected during a research survey carried out between January 23 and February 13, 2016,

7. Description of the tagging process and the development of a cradle for optimum landing and measuring of large fish followed by the Spanish F/V Tronio

   Abstract:  During the 2017/18 season the Spanish F/V Tronio fished in Statistical Subarea 88.1 and Division 58.4.1 where the latter area required a tag rate of five fish per ton greenweight caught and also where the overall size of the fish exceeds 115cm. The tagging station on the FV Tronio is on

8. Estimates of abundance of Dissostichus eleginoides and Champsocephalus gunnari from the random stratified trawl survey in the waters surrounding Heard Island in Division 58.5.2 for 2018

   Abstract:  The annual random stratified trawl survey (RSTS) of 2018 around Heard Island and McDonald Island (HIMI) in Division 58.5.2 took place from the end of March to the end of April, with the completion of 163 stations plus eight extra fine mesh hauls. The survey was conducted on the FV Atlas

9. A preliminary assessment for mackerel icefish (Champsocephalus gunnari) in Division 58.5.2, based on results from the 2018 random stratified trawl survey

   Abstract:  The annual random stratified trawl survey was undertaken in Division 58.5.2 in the vicinity of Heard Island and McDonald Islands during April 2018. This paper provides an updated growth model and a preliminary assessment for mackerel icefish (Champsocephalus gunnari) population structure

10. Report on fishing effort and seabird interactions during the season extension trials in the longline fishery for Dissostichus eleginoides in Statistical Division 58.5.2

    Abstract:  CCAMLR-XXXIV (para. 5.68) endorsed new pre-season (1–14 April) and post-season (15–30 November) trial season extensions, in addition to an existing pre-season (15–30 April) and trial post-season (1–14 November) extension in the Patagonian toothfish longline fishery in Statistical
