1. Increase in relative abundance of fjord Notothenia rossii in Potter Cover, South Shetland Islands, after the decrease associated with commercial fishing in the area

   Abstract:  A monitoring program of demersal fish in inshore sites of the South Shetland Islands has continued in Potter Cove from 1991 to 1999, covering a continuous sampling period of sixteen years and in Harmony Cove, Nelson Island, in the austral summer 1995/96. The decline in trammel net

2. Notes on the availability of three important finfish species in offshore waters of the lower South Shetland Islands (Subarea 48.1)

   Abstract:  In 1998, an offshore scientific trawl survey of bottom fish sampling within the 50-500 m isobath of the lower South Shetlands Islands (King George Island to Low Island) was conducted. In addition, the abundance of two commercially important Antarctic fish, Notothenia rossii and

3. Changes in biomass of eight species of finfish around the South Orkney Islands (Subarea 48.2) from three bottom trawl surveys

   Abstract:  Stocks of finfish around the South Orkney Islands (Subarea 48.2) suffered substantial declines during the period the fishery was open from split year 1977/78 through 1989/90. Scientific bottom trawl surveys of finfish biomass within the 500 m isobath of the South Orkney Islands have been

4. Revised estimates of seabed areas within the 500 m isobath of the South Orkney Islands (Subarea 48.2) and consequences for standing stock biomass estimates of nine species of finfish

   Abstract:  A revised bathymetric map of the South Orkney Islands (Subarea 48.2) was generated using several integrated bathymetric databases and newly available acoustic seafloor data. The region extends from 60.2ºS-62.2ºS latitude and 42.5º-47.5º longitude. From the integrated data sets, areas of

6. Avoidance of incidental mortality of seabirds and the implementation of Conservation Measure 169/XVII in Statistical Subarea 88.1 in the 1998/99 season

   Abstract:  New Zealand conducted Longline weighting trials during the 1998/99 fishery for Dissostichus spp. in Sub-area 88.1. Daylight setting was allowed south of 65°S in Sub-area 88.1 under special provisions in Conservation Measure 169/XVII. The provisions included strictly applied line

9. Sexual dimorphism and sexual segregation in foraging strategies of northern giant petrels Macronectes halli during incubation

   Abstract:  Giant petrels (Macronectes spp) are the most sexually dimorphic of all seabirds. We used satellite-tracking and mass change during incubation to investigate the influence of sexual size dimorphism, in terms of the intersexual food competition hypothesis, on foraging and fasting

10. Foraging partitioning between giant petrels Macronectes spp. and its relationship with breeding population changes at Bird Island, South Georgia

    Abstract:  We tracked by satellite the foraging trips of males and females of the two sibling species of giant petrels, Macronectes halli and M.giganteus, breeding sympatrically at Bird Island (South Georgia, Antarctica), during the incubation period (November-December). Size of the activity range
