2. Estimating by-catch from CCAMLR data

   Abstract:  Quantifying the catch rates and biomass of by-catch species on CCAMLR’s fishing grounds is an essential component of the assessment advice prepared by WG-FSA. However, such analyses are problematic because the CCAMLR datasets are incomplete and have a high occurrence of ‘missing catch

3. Testing the performance of a recompiled version of TrawlCI to calculate confidence intervals of abundance in surveys of Patagonian toothfish (Dissostichus eleginoides) and mackerel icefish (Champsocephalus gunnari)

   Abstract:  A version of the confidence interval calculating program TrawlCI was recompiled to enable it to be run within the DOS emulator of recent versions of the Microsoft Windows operating system. The performance of the recompiled version was compared with that of the original version. The

4. Initial development of operating models for testing management procedures for the toothfish (Dissostichus eleginoides) resource in the Prince Edward Islands vicinity

   Abstract:  Three Operating Models (OMs) reflecting an optimistic, an intermediate, and a pessimistic current status for the toothfish resource in the Prince Edward Islands are developed. These are planned for use for initial trials of candidate Management Procedures (MPs) to provide future TAC

5. Developing integrated assessments for Dissostichus eleginoides based on the CCAMLR precautionary approach

   Abstract:  This paper describes a possible method for implementing the precautionary approach in assessments of Dissostichus stocks when a number of different datasets are being integrated for estimating current biomass and age structure. Consideration is given to its application to the assessment

6. Examination of the characteristics of the fishery for Dissostichus eleginoides in the CCAMLR Statistical Subarea 48.3 and its implications on estimating trends in catch per unit effort

   Abstract:  We investigate the spatial and temporal (i.e. fishing season) variation both systematic and random in haul-by-haul catch and effort data from the longline fishery for Dissostichus eleginoides in Subarea 48.3. We concentrate on presenting the results of preliminary work on the potential

7. Age-structured production model for toothfish at South Georgia

   Abstract:  The ASPM model used by Agnew and Kirkwood (2004, WG-FSA-04/82) has been modified through the introduction of a new annual selectivity function, modelled as a unimodal, algebraically decaying function of age, with three easily interpretable parameters. When only a single selectivity curve

8. Selectivity-induced bias in growth parameter estimates

   Abstract:  A short simulation study has been carried out to investigate the size of the bias in estimates of growth parameters resulting from fish of different sizes having different probabilities of being included in catch samples. Fish were included in catch samples from the population with
