1. Models of tag shedding for double tagging as a function of time at liberty and approximate solutions for the single tagging model in CASAL

   Abstract:  The model of tag shedding implicit in CASAL is that of Kirkwood and Walker (KW) (1984) which models the annual tag shedding (i.e. loss) rate as a constant for individual tags. The CASAL software applies this model correctly for fish released with a single tag but does not have the

2. A preliminary examination of the length–weight relationship in Dissostichus eleginoides and D. mawsoni using data from the CCAMLR Scheme of Scientific Observation

   Abstract:  An investigation into use the length-weight relationship of Dissostichus eleginoides and D. mawsoni to separate the two species was undertaken using data from the CCAMLR Scheme of Scientific Observation. Although the ability to discriminate the two species using length and weight

3. Developments in the CCAMLR tagging program

   Abstract:  In order to assess the level of confidence in the link made, as well as the time and effort  taken to make the link, the Secretariat introduced a tag recapture link status code to identify the level of effort involved in linking a tag recapture to its tagging event.  For the 2011 season

4. SCÉNARIO D'AIRE MARINE PROTÉGÉE PRÉSENTÉ PAR LA NOUVELLE-ZÉLANDE POUR LA RÉGION DE LA MER DE ROSS

   Abstract:  New Zealand has been an active contributor to the CCAMLR MPA planning process, and with the USA submitted to the CCAMLR MPA Workshop paper WS-MPA-25 (Sharp and Watters 2011), including a draft New Zealand MPA scenario for the Ross Sea region. This paper presents the New Zealand scenario

5. Fishery-based research in exploratory fisheries

   Abstract:  This paper summarises the data collection requirements for the exploratory fisheries for Dissostichus spp. and the general characteristics of the research hauls which may assist WG-FSA to determine the extent to which the available data may be used in developing assessments for these

6. Preliminary review of Antarctic toothfish maturity in the Ross Sea

   Abstract:  Results of comparative histological analysis of gonads of female and male Antarctic toothfish Dissostichus mawsoni caught by Russian longliners in the Ross Ross Sea of the Pacific sector in 2004/2005- 2006/2007 seasons are presented. Morphological indices of females and males, age,

7. Stock assessment of the Patagonian toothfish, Dissostichus eleginoides, harvested by the French fishery at Kerguelen Islands (Division 58.5.1 of the CCAMLR)

   Abstract:  A stock assessment of the Patagonian toothfish (Dissostichus eleginoides) at Kerguelen Island (division 58.5.1 of the CCAMLR) was undertaken with the modeling software CASAL, using different statistical and biological datasets: abundance estimation from the POKER 1 and 2 scientific

8. Results from the groundfish survey conducted in CCAMLR Subarea 48.3 in January/February 2011

   Abstract:  The 2011 groundfish survey took place at South Georgia and Shag Rocks on the FV Sil between the 27th January and 6th February 2011. 87 random hauls were completed, with good coverage across the shelf. Catch-weighted length frequencies of mackerel icefish indicated that 3+ sized fish

9. Preliminary assessment of mackerel icefish, Champsocephalus gunnari, in Subarea 48.3 using a length based population dynamics modelv

   Abstract:  A length-based projection model is used to estimate catch limits for the 2011/12 fishing season for Champsocephalus gunnari in CCAMLR sub area 48.3. The model is initialised using estimated numbers at length derived from survey length density and biomass density data, removing the need

10. The diet of toothfish species Dissostichus eleginoides Smitt and D. mawsoni Norman with overlapping distributions around the South Sandwich Islands, Southern Ocean

    Abstract:  The diet of Antarctic toothfish (Dissostichus mawsoni) and Patagonian toothfish (D. eleginoides) was examined around the south sandwich islands in the southern ocean, one of few regions with overlapping populations of the two species. Despite large differences in the proportion of
