1. Manual for age determination of Antarctic toothfish (Dissostichus mawsoni)

   Abstract:  Production of an age determination manual for Antarctic toothfish (Dissostichus mawsoni) is part of the focus of the SC-CAMLR workplan for 2010. The aim of the current work was to produce a manual that presents standard protocols used by the National Institute of Water and Atmospheric

2. Stomach contents of Antarctic toothfish (Dissostichus mawsoni) from the Ross Sea region in 2010 and a comparison with 2003

   Abstract:  The stomach contents of 273 Dissostichus mawsoni captured by bottom longline in the Ross Sea region during the 2010 summer fishing season were analysed. The D. mawsoni sampled were caught in 640–2127 m depths and ranged between 78 and 181 cm TL. A total of 198 stomachs contained prey

3. A characterisation of the toothfish fishery in Subareas 88.1 and 88.2 from 1997/98 to 2009/10

   Abstract:  The exploratory fishery for Dissostichus spp. Has now been operating for 14 years in Subarea 88.1 and for 9 years in Subarea 88.2. This report summarises the timing, depth, and location of fishing together with the catch of Dissostichus spp and bycatch species by year for the period 1997

4. Updated species profile for Antarctic toothfish (Dissostichus mawsoni)

   Abstract:  A species profile, covering aspects of the biology, fisheries and stock assessment of both toothfish species was first completed by Everson (2002). A new species profile, specifically for Antarctic toothfish (Dissostichus mawsoni, Norman), was developed by Hanchet (2006). That document

5. Population assessment of Patagonian toothfish in the north of Subarea 48.4 – 2010 update

   Abstract:  The target tagging rate of 5 fish per tonne was exceeded by both vessels, with 232 D. eleginoides tagged and released in 2009/10, bringing the total to 1,547 in all seasons; There were 18 D. eleginoides tag recaptures in 2009/10, a total of 72 in all seasons; The length-frequency of 2009

6. Proposal for an extension to the mark-recapture experiment to estimate toothfish population size in the South of Subarea 48.4

   Abstract:  A three‐year tagging study in the South of Subarea 48.4 was initiated in the 2008/09 fishing season with the aims of  providing the data required for assessments of the population structure, size, movement and growth of both Dissostichus eleginoides and Dissostichus mawsoni in the South

7. Estimation of natural mortality for the Patagonian toothfish at Heard and McDonald Islands using catch-at-age and aged mark-recapture data from the main trawl ground

   Abstract:  Attempts to estimate natural mortality, as a single constant M, simultaneously with other model parameters in integrated assessments via CASAL for the Heard and McDonald Islands (HIMI, CCAMLR Division 58.5.2) Patagonian toothfish (Dissostichus eleginoides) fishery have been unsuccessful.

8. Evaluating the impact of multi-year research catch limits on overfished toothfish populations

   Abstract:  In stocks that have been depleted by overfishing, the benefits of additional fisheries removals for research purposes need to be evaluated against the risks that such catches may contribute to delaying the recovery of such stocks. Through simulating a Dissostichus eleginoides stock that

9. Evaluating length-frequency data and length-based performance indicators in new and exploratory fisheries

   Abstract:  Length-frequency data are routinely collected in CCAMLR’s fisheries and used as inputs to stock assessments. In CCAMLR’s new and exploratory fisheries, stock assessment techniques are still in development and robust conclusions on stock status based on length-frequency data alone have

10. Reports on stock status and biological information on toothfish obtained from the scientific research survey by Shinsei Maru No. 3 in 2009/10 in the SE sector of Division 58.4.3b

    Abstract:  In accordance with the Conservation Measure 41-07 (2009), a survey was conducted in order to collect information for the stock status and biological information on toothfish in the southeast sector (24 allocated points) of Division 58.4.3b (Banzare Bank), using a commercial bottom
