3. On peculiarities of icefish (Champsocephalus gunnari) vertical distribution in different habitats

   Abstract:  The significant similarity of Kerguelen and South Georgia icefish Ch.gunnari populations ecology has been revealed. Fish of all lengths and ages are planktonphages. Fish of the first two age groups have been continuously found in the pelagic layer off South Georgia and Kerguelen-Heard.

4. Peculiarities of icefish Champsocephalus gunnari (Channichthyidae) distribution in South Georgia area during the surveys made by STM Atlantida in 2000 and 2002

   Abstract:  Reasons of differences in icefish distribution and biomass assessment during two surveys made by STM “Atlantida” are revealed. Availability of large icefish concentrations in 2000 in the northwest shelf area in 10-100m layer resulted in formation of adult fish aggregations in water

5. Estimates of bird by-catch by IUU vessels in Subarea 48.3, 1998–2001

   Abstract:  Estimates of bird catches by IUU fishing made using the new method presented by Agnew and Kirkwood last year (WG-FSA-02/4 & 5) are updated to take account of the comments of the working group. Last year we suggested that the Isabel data from 1997 were rather atypical of bird catch

6. The survivorship of rays discarded from the South Georgia longline fishery

   Abstract:  Skate post haulage survival experiments were conducted by one Chilean fishing vessel throughout the months of May and June, during 2003 toothfish fishing season in Subarea 48.3. From these results we can conclude that depth has a significant influence on the mortality of skate, with a

7. By-catch of rays in the 2002/03 toothfish fishery around South Georgia

   Abstract:  The 2002/2003 fishing season was the first in which three new policies for rays were tried: • It was the first in which vessels were asked to cut off all rays at water level to assist survival and conservation of rays; • It was the first in which very good quality information was

9. Diet of two icefish species from the South Shetland Islands and Elephant Island, Champsocephalus gunnari and Chaenocephalus aceratus 2001–2003

   Abstract:  The summer diet of two species of icefishes (Channichthyidae) from the South Shetland Islands and Elephant Island, Champsocephalus gunnari and Chaenocephalus aceratus, was investigated from 2001 to 2003. C. gunnari fed almost exclusively on krill (Euphausia superba) in all years. The

10. Otolith microstructure of juvenile fish, the first annulus radius and pelagic stage duration of icefish Champsocephalus gunnari (Channichthyidae) in the South Georgia area

    Abstract:  On the basis of the results of the trawl-acoustic survey in February-March 2002, the microstructure analysis of otoliths of juvenile icefish of 5.5-13.3 cm in length was carried out. Fish studied represent a mixture of two year-classes of 1999-2000 and 2000-2001. The mean width of the
