1. The recent decline in recruitment of Gobionotothen gibberifrons in the South Shetland Islands (CCAMLR Subarea 48.1)

   Abstract:  Commercial exploitation of fish stocks around Elephant Island and the lower South Shetland Islands ceased after the 1989/90 season. One of the larger and most abundant species in the area, Gobionotothen gibberifons, was only lightly exploited compared to more northerly fishing grounds

2. Characteristics of population-genetic structure of Antarctic toothfish (Dissostichus mawsoni) from near-continental seas of Pacific, Indian and Atlantic sectors of the Antarctica

   Abstract:  Population-genetic structure of Antarctic toothfish (Dissostichus mawsoni) was investigated not once during the last decade and before, but in this work we present our data on DNA-analysis of recent samplings of toothfish from CCAMLR Subareas – 88.1, 58.4.1, 58.4.2 and 48.6. Our findings

3. Population structure and connectivity of an important pelagic forage fish in the antarctic ecosystem, Pleuragramma antarcticum, in relation to large scale circulation

   Abstract:  Ocean circulation has been identified as a major process controlling the distribution of biological material in marine systems.  Large-scale transport by the Antarctic Circumpolar Current (ACC), the Ross and Weddell Gyres, and the Antarctic Coastal Current can promote spatially complex

4. Analysis of the by-catch of Channichthys rhinoceratus and Lepidonotothen squamifrons from the fisheries at Heard Island and the McDonald Islands (Division 58.5.2)

   Abstract:  The unicorn icefish, Channichthys rhinoceratus and the grey rock cod, Lepidonotothen squamifrons are among the most common species bycaught in the toothfish and mackerel icefish trawl fisheries at Heard Island and McDonald Islands (HIMI) (Division 58.5.2). These species are rarely taken

5. The annual random stratified trawl survey to estimate the abundance of Dissostichus eleginoides and Champsocephalus gunnari in the Heard Island region (Division 58.5.2) for 2012

   Abstract:  The annual random stratified trawl survey at HIMI was completed in March to May of 2012. A codend liner, usually in place for the entire survey, was used only in the icefish strata, Gunnari Ridge, Plateau Southeast and Plateau West, and in a repeat of the hauls in Ground B. Catches in

6. A preliminary assessment of mackerel icefish (Champsocephalus gunnari) in Division 58.5.2, based on recent survey results

   Abstract:  The annual Random Stratified Trawl Survey was undertaken in Division 58.5.2 in the vicinity of Heard Island during April-May 2011. This paper provides a preliminary assessment of mackerel icefish population structure, abundance and yield for the area of Division 58.5.2 to the west of 79

7. The relative impacts of Autolines and Spanish longlines on vulnerable marine ecosystems

   Abstract:  The Commission aims to protect vulnerable marine ecosystems (VMEs) and has established several Conservation Measures that limit bottom fishing and require data collection by fishing vessels.  Members have made substantive and important scientific contributions to support the Commission’s

8. Robust characterisation of the age structure, growth and recruitment of toothfish in the Macquarie Island and Heard Island and McDonald Islands fisheries

   Abstract:  Between 2010 and 2012, AAD, Australian Fisheries Management Authority and Australian fishing industry provided funds to conduct high throughput ageing of toothfish otoliths. 5780 otoliths, collected during the 2000-2011 fishing seasons in Division 58.5.2 and outside the CCAMLR area at

9. Population assessment of Patagonian toothfish in Subarea 48.4

   Abstract:  This paper presents an update of the assessment of toothfish (Dissostichus spp.) in Subarea 48.4. The Subarea is divided into two management regions and assessed using a CASAL assessment of D. eleginoides in the northern region and a simple Petersen biomass estimate derived for D.

10. Indexing maturation of Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea region

    Abstract:  The longline fisheries for Antarctic toothfish (Dissostichus mawsoni) in subareas 88.1 and 88.2 have provided more than a decade of observations to aid in understanding the life history and ecology of toothfish. Updated spawning ogives for males and females support the currently used
