Re-organisation of WG-FSA Report
Abstract: In 2003, WG-FSA and the Scientific Committee identified the need to rewrite and restructure the WG-FSA report. In early 2004, the extend and nature of the work required was developed in consultation between the Conveners of WG-FSA and WG-IMAF, and the Chair of the Scientific Committee,

Estimation of IUU catches of toothfish inside the Convention Area during the 2009/10 fishing season
Abstract: The paper presents an estimate of IUU catches of toothfish during the 2009/10 fishing season, using the standard, compliance derived methodology. The paper was revised on 4 October 2010 to take into account new information submitted in respect of two vessels fishing in Divisions 58.4.1

Application of continuous time Markov chains to modelling animal movement: estimation of movement rates and retention times for Patagonian toothfish
Abstract: The study of animal movement and distribution has been a central focus in ecology since the inception of the science. However, continuous-time, discrete state models have received relatively little application in data analyses or prediction in studies movement. Here we develop a

Proposed trawl survey report format
Abstract: Trawl surveys are used in CCAMLR waters to estimate abundance of juvenile toothfish (Dissostichus eleginoides) and icefish (Champsocephalus gunnari). Documentation of some past trawl surveys has been insufficient to allow members of WG-FSA to fully interpret the survey results. This

A von Bertalanffy growth model for Division 58.5.2 fitted to length-at-age data and a comparison of predicted with observed growth from mark–recapture data
Abstract: Length-at-age data for the Patagonian toothfish (Dissostichus eleginoides) caught by trawl in Heard Island fishery were fitted using a von Bertalanffy (VB) growth model taking into account variable probability (VP) sampling of fish that were aged. Sub-sampling of random length frequency

Revised estimates of the biological parameters for Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea
Abstract: This report updates the estimates of the biological parameters for Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea (Subareas 88.1 and SSRUs 88.2A–B). We present revised estimates of the von Bertalanffy growth curves, length weight relationship, and natural mortality based on

Developments towards an investigation of potential bias from the analysis of tag–release and recapture data in Ross Sea Antarctic toothfish abundance estimates
Abstract: This report outlines developments towards evaluating bias in abundance estimates for the current tagrecapture programme for Antarctic toothfish in the Ross Sea. We present an initial approach that uses the current data on catch (C2 data), tag-recovery effort and tag-release data from

An update on the development of a management procedure for the toothfish (Dissostichus eleginoides) resource in the Prince Edward Islands vicinity
Abstract: Two Operating Models (OMs) reflecting an “Optimistic” and a “Pessimistic” current status for the toothfish resource in the Prince Edward Islands region that were developed last year are updated given further data. These models are for use for initial trials of candidate Management
