1. By-catch in Australian fisheries in Divisions 58.5.2, 58.4.2 and 58.4.3 during the 2002/03 and 2003/04 fishing seasons

   Abstract:  This paper presents bycatch information for the Australian fisheries in Divisions 58.5.2, 58.4.2 and 58.4.3, with estimates of total removals by fishing ground for the 2002/2003 and 2003/2004 seasons. Bycatch in the trawl fisheries was low, approximately 1 to 2% of the total catch

2. Alternative method of parameters accuracy calculation in CMIX procedure applied to toothfish recruitment estimation

   Abstract:  The paper presents the application of the bootstrap method to estimate accuracy of mixture distributions parameters. The method allows to estimate statistical characteristics not only component densities but another parameters: mean length of components, their standard deviations or

3. A comparison of two different methods to age mackerel icefish (Champsocephalus gunnari) at South Georgia

   Abstract:  Age determinations estimated by means of otoliths and age classes derived from CMIX analysis have been compared in Champsocephalus gunnari using material collected around South Georgia during four Russian surveys in 1988, 1990, 2000 and 2002. Considerable differences in age estimates

4. Report on the status of wandering, black-browed and grey-headed albatrosses at South Georgia

   Abstract:  Surveys of all known breeding sites of wandering, black-browed and grey-headed albatrosses were carried out at South Georgia in the 2003/04 breeding season. Wandering albatrosses were censused by ground counts, and black-browed and grey-headed albatrosses mainly by yacht-based digital

5. Report on the effectiveness of integrated weight (fast sinking) longlines in reducing the mortality of white-chinned petrels and sooty shearwaters in autoline longline fisheries

   Abstract:  The difference in the number of white-chinned petrels (Procellaria aequinoctialis) and sooty shearwaters (Puffinus griseus) killed by unweighted longlines (UW; mean sink rate to 20 m depth: 0.11 m/s) and longlines containing 50 g lead/m integrated weight (IW; mean sink rate: 0.24 m/s)

6. Proposal for the removal of night setting requirement for autoline vessels fishing in Division 58.5.2

   Abstract:  This document seeks support to allow line setting operations by autoline vessels fishing in Division 58.5.2 to occur at any time of the day/night cycle. The proposal forms part of an adaptive approach to management, which considers the risk status of the fishery, knowledge on the

7. A simulation approach to the evaluation of recruitment surveys for D. eleginoides for the Heard Island Plateau region (Division 58.5.2)

   Abstract:  Assessments of long-term sustainable yield using the Generalised Yield Model (GYM) and the setting of total allowable catches (TAC) for Patagonian Toothfish, Dissostichus eleginoides, for the Heard Island Plateau region (Division 58.5.2) are based on data obtained from annual random

8. Description of an AD Model Builder implementation of the exact time of release and recapture stock assessment model of Tuck et al. (2003)

   Abstract:  Tuck et al. (2003) describe an exact time of release and recapture stock assessment model and applied it to the stock of Patagonian Toothfish, Dissostichus eleginoides,at Macquarie Island that have been fished by Australian trawlers from November 1994. This work was previously presented

9. Preliminary assessment of mackerel icefish (Champsocephalus gunnari) for the Heard Island Plateau region (Division 58.5.2) based on a survey in May 2004

   Abstract:  A survey of Mackerel Icefish, Champsocephalus gunnari,was undertaken in Division 58.5.2 in the vicinity of Heard Island in May 2004 to provide the information for an assessment of short-term annual yield in the 2004/2005 CCAMLR season. This paper provides a preliminary assessment of
