1. A preliminary assessment of age and growth of eel cod (Muraenolepis sp.) and violet cod (Antimora rostrata) in the Ross Sea, Antarctica

   Abstract:  Samples of an eel cod (Muraenolepis sp.) and violet cod (Antimora rostrata) were obtained from the bycatch of the longline fishery for toothfish (Dissostichus mawsoni and D. eleginoides) in the Ross Sea, Antarctica. Counts of zones visible in sectioned otoliths were used to estimate

2. A preliminary assessment of age and growth of Antarctic silverfish (Pleuragramma antarcticum) in the Ross Sea, Antarctica

   Abstract:  Antarctic silverfish (Pleuragramma antarcticum) were sampled during a trawl survey in the Ross Sea, Antarctica. Biological data, including fish length, weight, sex, gonad maturity, liver weight and diet analysis were collected from 311 specimens. Standard length and weight were well

3. 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

4. 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

5. 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

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 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

9. Distribution and population structure of Dissostichus eleginoides and D. mawsoni on BANZARE Bank (CCAMLR Division 58.4.3b), Indian Ocean, Antarctic

   Abstract:  Distribution, relationship between sizes and depths, sex ratio, size composition and maturity condition for Dissostichus eleginoides and D. mawsoni were investigated on Banzare Bank, using the biological data sampled by a Japanese commercial fishing vessel during austral summer from 2006

10. Preliminary studies on age and growth of Dissostichus eleginoides in the Ob-Lena Bank

    Abstract:  Preliminary studies on the age and growth of Dissostichus eleginoides sampled in the 2007/08 season in the Ob-Lena Bank were carried out. The ages of 214 of 3,013 fish sampled by Observers were estimated. The estimated ages ranged from 5 to 46 years for males and from 5 to 50 years for
