1. Some components of uncertainty in the CCAMLR 2000 acoustical survey of krill

   Abstract:  Quickly studied and quantified were sources of uncertainty in the CCAMLR 2000 acoustical estimate of krill abundance in FAO statistical area 48. The variance in system calibration was evaluated in relation to the effects of variant water temperature and salinity on sound speed, sound

4. Longline fishing at Tristan da Cunha: impact on seabirds

   Abstract:  Tristan da Cunha and Gough Islands in the central South Atlantic Ocean support globally important seabird populations. Two longline fisheries occur within Tristan’s Exclusive Economic Zone: a pelagic fishery for tunas and a demersal fishery for bluefish and alfoncino. Fishery observers

5. What do we know about fish stocks in the Southern Scotia region? A review and prospects for future research

   Abstract:  Work on finfish in the southern Scotia Arc was restricted to taxonomy until the end of the 1960’s. Commercial exploitation, primarily on mackerel ice fish, Champsocephalus gunnari, and marbled notothenia, Notothenia rossii, started around the South Orkney Islands (60 – 62° / 43 – 47° W)

7. Biological features of the icefish Champsocephalus gunnari from commercial catches in Subarea 48.3 during the period from 8 December 1999 until 31 January 2000

   Abstract:  In the period from 11 December 1999 to 31 January 2000 Russian trawler "Zakhar Sorokin" carried out fishing the icefish Champsocephalus gunnari feeding consent rations in the western shelf of the South Georgia Island. Icefish 26-40 cm in length, with the average size of 30.3 cm

8. UK groundfish survey in Subarea 48.3 (South Georgia and Shag Rocks), January 2000

   Abstract:  A survey was conducted by the UK around South Georgia and Shag Rocks, Subarea 48.3, from 11 January to 2 February 2000, using the FV Argos Galicia. The design followed similar surveys by the UK conducted throughout the late 1980s and 1990s. The swept area estimates of the standing stock

9. Notes on the biology of the South Georgia ray, Raja georgiana

   Abstract:  Morphological information is given on specimens of Raja georgiana that were caught during a demersal trawl survey in Subarea 48.3, South Georgia. It is concluded that, in spite of allometric growth, proportional measurements are best referenced to total length rather than disc width.

10. Crab by-catch in the experimental toothfish pot fishery around South Georgia, 2000

    Abstract:  Trials of a method of fishing for toothfish using pots were undertaken by FV Argos Georgia from March to May 2000. A significant bycatch of crabs was encountered. Paralomis spinosissima occurred in shallow water, generally shallower than 800m. P. anamerae, which has not been reported for
