Evaluating the impact of multi-year research catch limits on overfished toothfish populations
Abstract: In stocks that have been depleted by overfishing, the benefits of additional fisheries removals for research purposes need to be evaluated against the risks that such catches may contribute to delaying the recovery of such stocks. Through simulating a Dissostichus eleginoides stock that

Using mark-recapture and catch-age data to estimate fishing and natural mortality for the Patagonian toothfish at South Georgia
Abstract: This paper develops a Bayesian mark-recapture model for estimating both fishing and natural mortality, and integrates catch-at-age data into the estimation model, to aid in distinguishing between natural and fishing mortality. The model essentially follows tagged cohorts, with the

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

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

Review of the use of survey data and length-at-age models in the assessment of Dissostichus eleginoides in the vicinity of Heard Island and McDonald Islands (Division 58.5.2)
Abstract: This paper reviews the data used to estimate the abundance of juvenile Dissostichus eleginoides in Division 58.5.2 and examines the sensitivity of the assessment of yield to these results. Primarily, it is proposed to revise the use of historical survey data by reassigning them to the
