1. Effect of a shore-based sampling program on Notothenia coriiceps populations

   Abstract:  The effect of an intensive sampling programme on an inshore population of Notothenia coriiceps was studied at Potter Cove, South Shetland Islands, by comparing catch data taken in successive summers of 1992/93 to 1994/95 at one specific zone (site 1) with those taken in the same last

2. Foraging ecology of grey-headed mollymawks at Marion Island in relation to longline fishing activity

   Abstract:  Grey-headed mollymawks Thalassarche chrysostoma are killed by longline fishing operations in the southern Indian Ocean. We studied the foraging ecology of breeding grey-headed mollymawks at Marion Island, by tracking their foraging trips and sampling their diets. During the incubation

3. Factors affecting the number and mortality of seabirds attending trawlers and longliners in the Kerguelen area

   Abstract:  The factors affecting the number and the mortality of seabirds attending long-liners and trawlers fishing in the Kerguelen area were studied during four successive seasons (1994-1997), based on observations carried out onboard by dedicated observers. Twenty-four species of seabirds were

5. Preliminary analysis of seabird by-catch using CCAMLR observer data

   Abstract:  We used data collected by CCAMLR International Scientific Observers in 1997 and 1998 to examine potential relationships between seabird incidental mortality rates on longline vessels fishing for Dissostichus eleginoides and various factors, including the nature and use of mitigating

6. 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

7. 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

8. 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

9. 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
