Abstract
The diet of Harpagifer antarcticus was studied at
two localities of the South Shetland Islands, Antarctica. The analysis of the
stomach contents of specimens collected in tide pools at Potter Cove, King
George Island, indicated that gammarid amphipods (mainly Gondogeneia sp.) were the main prey of this fish, followed by
polychaetes, gastropods and isopods. By contrast, the specimens from Harmony
Point, Nelson Island, which were recovered from stomach contents of Antarctic
shags Phalacrocorax bransfieldensis
feeding at depths to 46-110 m, preyed
almost exclusively on the Antarctic krill Euphausia
superba. These results are discussed and compared with previous studies.
