1. Updated models of the habitat use of Patagonian toothfish (Dissostichus eleginoides) on the Kerguelen Plateau around Heard Island and the McDonald Islands (Division 58.5.2)

   Abstract:  The Kerguelen Plateau supports the largest fishery for Patagonian toothfish (Dissostichus eleginoides) in the CCAMLR area, with landings of  >5000 t.yr-1 from the French EEZ (Division 58.5.1) around îles Kerguelen and 2730 t.yr-1 from the Australian EEZ around Heard and McDonald

2. Development of the Patagonian toothfish (Dissostichus eleginoides) tagging program in Division 58.5.2, 1997–2014

   Abstract:  Patagonian toothfish have been tagged during commercial fishing and research activities adjacent to Heard Island and the McDonald Islands (HIMI, CCAMLR Division 58.5.2) since 1998, with 27,679 toothfish tagged and released, and 4925 recaptures. The data derived from this program has been

3. A preliminary assessment of mackerel icefish (Champsocephalus gunnari) in Division 58.5.2, based on results from the 2014 random stratified trawl survey

   Abstract:  The annual Random Stratified Trawl Survey was undertaken in Division 58.5.2 in the vicinity of Heard Island during June 2014. 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° 20’

4. An update of the ageing program for Patagonian toothfish (Dissostichus eleginoides) at the Australian Antarctic Division, including a summary of new data available for the Integrated Stock Assessment for the Heard Island and the McDonald Islands fishery (Division 58.5.2)

   Abstract:  The Australian Antarctic Division (AAD) has recently received funding to continue an ageing program for the purposes of routine processing of Patagonian toothfish (Dissostichus eleginoides) otoliths from the Heard Island and McDonald Islands fishery. With the reinitiation of this program

5. Investigating the uncertainty of age determinations for Patagonian toothfish (Dissostichus eleginoides) and the implications for stock assessment

   Abstract:  We revised the method of Candy et al. (2012) to estimate the ageing error matrix (misclassification matrix) to address some issues regarding true ages not being the mode at the extremes of the matrix and a lack of smoothness in the probabilities for ages above 25 years. Positive errors

7. Report on the CCAMLR marine debris monitoring program

   Abstract:  Data on beach surveys, debris associated with seabird colonies, marine mammal entanglements and hydrocarbon soilings were received for 2014 from South Africa, the United Kingdom, and Uruguay. Non-fishing items such as plastics, packaging materials and wood remain the most common type of

9. The demersal fish communities of the shelf and slope of South Georgia and Shag Rocks (CCAMLR Subarea 48.3)

   Abstract:  Analysis of catch data from a deepwater trawl survey conducted at South Georgia and Shag Rocks in 2003 indicate that depth and region have a marked influence over demersal fish community structure at South Georgia and Shag Rocks. Three distinct, depth stratified fish assemblages were

10. A perspective on steepness, reference points, and stock assessment

    Abstract:  We provide a perspective on steepness, reference points for fishery management, and stock assessment. We first review published data and give new results showing that key reference points are fixed when steepness and other life history parameters are fixed in stock assessments using a
