1. Evaluating methods to assess yield of Patagonian toothfish (Dissostichus eleginoides) in CCAMLR Division 58.5.2

   Abstract:  This paper describes aspects of the Management Strategy Evaluation (MSE) being developed to evaluate possible management strategies for the Patagonian toothfish fishery in Division 58.5.2. As requested by the Subgroup on Assessment Methods, we elaborate the plausible operating models

2. Biological and fishery information for skates in Division 58.5.2

   Abstract:  This paper presents biological and fishery information available for skates from Division 58.5.2. Estimates of growth calculated from trawl-tagged, recaptured B. eatonii were 15 mm per year in total length and wing span, and 0.15kg per year in mass, indicating that this species is very

3. Two species of toothfish in two basic longline fisheries regions – Patagonian toothfish in Subarea 48.3 (South Atlantic) and Antarctic toothfish in Subareas 88.1 and 88.2 (South Pacific)

   Abstract:  Now after more then 30 years studies a most valuable commercial (target) species in the CCAMLR Area two species of genus Dissostichus. They have wide circumpolar distribution but difference in latitudes of the boundaries area distribution Patagonian and Antarctic toothfish. Our

5. Exploring the ASPM as an alternative method to estimate the Patagonian toothfish biomass at CCAMLR Subarea 48.3

   Abstract:  ASPM have been proposed and applied for Patagonian toothfish stock assessment at CCAMLR Subarea 48.3. Last results obtained from this model, discussed at WG-FSA (2004), do not show acceptable fit with standardized CPUE series and observed length proportions in the catches. In this paper,

6. Investigation of bias in the mark–recapture estimate of toothfish population size at South Georgia

   Abstract:  This paper investigates the influence of mixing of fish, and the uneven distribution of tag placements and recapture effort, on bias in the Petersen estimate. It does so by constructing a linear model of the South Georgia toothfish fishery, simulating fish movements within this system

7. Implementation of the modified Petersen mark–recapture method in S-Plus

   Abstract:  The mark-recapture method of estimating toothfish population size described last year, which uses a modification of the Petersen estimator to take account of mortality and selectivity, is implemented here in Splus code. Author(s):  A. Payne, D.J. Agnew and R. Hillary (United Kingdom)

8. Stratification of catch-at-length data using tree based regression: an example using Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea

   Abstract:  This paper presents a new approach to the stratification of catch-at-length data of Antarctic toothfish (D. mawsoni) in the Ross Sea. Tree based regression techniques were used to stratify the sampled catch based on the median length of Antarctic toothfish for each set using the observer

9. Simulation experiments and CCAMLR yield estimates using CASAL

   Abstract:  This paper describes an approach, using CASAL, to undertake operating model/estimation model experiments for Dissostichus spp., and methods for calculating CCAMLR yields using CASAL. We present an example model for the fictitious fishery on a fictitious species Dissostichus spurious

10. Descriptive analysis of the Antarctic toothfish (Dissostichus mawsoni) tagging scheme in the Ross Sea for the years 1997/98 to 2003/04

    Abstract:  A descriptive analysis of the toothfish tagging programme carried out in the Ross Sea since 2001 is presented for the first time. Tag-release and tag-recapture data are presented for both toothfish species for Subareas 88.1 and 88.2 for New Zealand vessels only. This is because data from
