1. Using acoustic echo counting to estimate grenadier abundance in the Ross Sea (SSRU88.1I)

   Abstract:  Grenadiers (Macrourus spp.) are the main bycatch species in the exploratory longline fishery for toothfish in the Ross Sea. Previous studies concluded that acoustics methods could be used to index the relative abundance of grenadiers and be useful for exploring spatial distribution.

2. Brief analysis of tag-recapture data in Statistical Subarea 48.4

   Abstract:  This paper presents an analysis of data gained from an eight-year tagging programme of Patagonian toothfish (Dissostichus eleginoides) in Subarea 48.4. It describes the tagging procedure, the information gained about biology, growth and movement of Patagonian toothfish, and looks at the

3. Proposal for a longline survey of toothfish in the northern Ross Sea region (SSRUs 88.2 A and B)

   Abstract:  We propose a multi-year and multi-member research plan using standardised longline gear to sample the toothfish populations in the northern areas (61°- 66° S) of SSRUs 88.2A–B. The purpose of the research as requested by the Scientific Committee (SC-CAMLR XXXII, paragraph 3.76) is to

4. Medium-term research plan for the Ross Sea toothfish fishery

   Abstract:  The aim of this paper is to review the management of the Ross Sea toothfish fishery and to identify key research objectives for the fishery over the next 3–5 years in relation to Article II of the Convention. The paper focuses primarily on Antarctic toothfish, as catches of Patagonian

5. Towards the development of an assessment of stock abundance for Subarea 88.2 SSRUs 88.2C–G

   Abstract:  This paper frames a discussion for improving the assessment of toothfish abundance for SSRUs 88.2C–G. We initially provide a characterisation of the fishery and a summary of available tagging and length frequency data. Although 880 tagged fish have been released in this region, only 2

6. Methodology for automated spatial sea ice summaries in the Southern Ocean

   Abstract:  Sea ice is recognised as a core driver of both ecosystem dynamics and fishery performance in the Southern Ocean. Sea ice can limit access to fishing grounds, for both commercial fishing and scientific research. Although satellite data are available and have been used for ecosystem

7. Comparison of age readings by two otolith preparation techniques and readers

   Abstract:  During the 2012 CCAMLR toothfish ageing workshop, otoliths from 31 Antarctic toothfish were exchanged between Russia and New Zealand ageing programmes to compare consistency in ages estimated by different readers and using different methods. Both “break and burn” and “bake and embed”

8. Report on season extension trials in the Patagonian toothfish longline fishery in CCAMLR Statistical Division 58.5.2

   Abstract:  This paper reports on the trial of daytime fishing during the 1-15 April pre-season extension, in the Patagonian toothfish longline fishery in statistical division 58.5.2. During the 1-15 April pre-season extension two vessels fished, and all setting was carried out during nautical dusk

9. The 2014 annual random stratified trawl survey in the waters of Heard Island (Division 58.5.2) to estimate the abundance of Dissostichus eleginoides and Champsocephalus gunnari

   Abstract:  The annual random stratified trawl survey (RSTS) at HIMI was conducted during June of 2014, with the completion of 158 stations. An additional five stations were completed at Shell Bank, which had not been sampled since 2005. The catches of C. gunnari were less than half of those in 2013

10. 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
