From the beginning of the
Argentine scientific activities at Jubany Station in King George Island, South
Shetland Islands, in 1982, several aspects of the biology of inshore demersal
fish species were studied in the compass of the Ichthyology Project of the Argentine
Antarctic Institute (AAI) (see Barrera-Oro
and Casaux, this issue).
Considering the importance
of the predator-prey interactions between birds/mammals and fish in the
Antarctic ecosystem and the scarce information available on this matter from
the South Shetland Islands, a research program co-ordinated by the Ichthyology,
Birds and Mammals projects of the AAI was established in 1990 to understand on
this matter. The initial studies were focused on the diet of the Antarctic Shag
at different localities of the South Shetland Islands. Similar studies were
also carried out on the South Polar Skua and on the Cape Petrel. Recently, the
Weddell seal and the Antarctic fur seal were also included as target species of
the program. In this review we summarise briefly the main results of this
research program.
