1. 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

2. 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

3. 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,

4. 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,

8. Brief information on the results of the bottom trawling survey at RV Atlantida in February 2000 in South Georgia subarea (48.3)

   Abstract:  In February 2000 the bottom trawling survey was carried out in Subdivision of South Georgia (48.3) to assess the main commercial and promising near-bottom and bottom fish species. The data on distribution, biology, minimal (relative) biomass and abundance of fishes were obtained. Author
