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

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

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

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

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

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.

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

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

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

Krill population dynamics at South Georgia: implications for ecosystem-based fisheries management
Abstract: The South Georgia region supports a large biomass of krill that is subject to high interannual variability. The apparent lack of a locally self-maintaining krill population at South Georgia means that understanding the mechanism underlying these observed population characteristics is
