Seabird by-catch in the Patagonian toothfish longline fishery at the Prince Edward Islands: 1999–2000
Abstract: This paper summarises seabird bycatch during the fourth year (July 1999-June 2000) of sanctioned longline fishing for Patagonian toothfish Dissostichus eleginoides in the Exclusive Economic Zone around South Africa's Prince Edward Islands. Data were obtained from fishery observers

Standardised estimates of D. eleginoides catches per effort in Subarea 48.3 using information for 1985/86–1990/91 seasons
Abstract: A brief description of hawl-by-hawl data sets from Ukrainian commercial vessels fishing tooth-fish in Subdivision 48.3 during 1986-199 1 is presented. The fishery was mainly carried out in summer months off the eastern South Georgia and at Shag Rocks. The length frequency modes amounted

Integration of CPUE data into assessments using the generalised yield model
Abstract: For the last 3 years, WG-FSA has accorded high priority to development of a method to integrate different indicators of stock status into assessments using the generalised yield model (GYM). In this paper, we propose a method, based on use of the sampling/importance-resampling algorithm,

A survey of fish stocks in the Heard Island and McDonald Islands region in the 1999/2000 season and a comparison of the abundances of selected species with those obtained in previous surveys
Abstract: A random stratified trawl survey was conducted in May 2000 to assess the abundance of icefish, Champsocephalus gunnari, and juvenile pre-recruit toothfish, Dissostichus eleginoides, on the Heard Island Plateau and Shell Bank. Abundances and length density plots of these species plus two

A revision of yield and catch controls for managing the mackerel icefish (Champsocephalus gunnari) fishery in the vicinity of Heard Island and McDonald Islands
Abstract: A recent 2000 survey of mackerel icefish in the vicinity of Heard Island enabled a revised estimate of yield for the coming 2 seasons. While the biomass of icefish appears lower than in previous years, it is dominated by a strong age 2 year class. Estimates of yield for the Heard Island

Update to recruitment series for Patagonian toothfish in the Heard Island region
Abstract: The recent fish survey at in the vicinity of Heard Island in 2000 has provided estimates of recruitment for at least one new cohort (1996) and another estimate of the 1995 cohort. The older cohorts are likely to be distributed more widely than the shallow part of the Heard Plateau,

An exact time of release and recapture stock assessment model applied to Macquarie Island Patagonian toothfish (Dissostichus eleginoides)
Abstract: This paper presents an assessment of the harvested population of Patagonian toothfish at Macquarie Island based on data from a tag-recapture experiment initiated during the 1995/96 fishing season. Population models that include dynamics of tagged and un-tagged fish, daily releases,
