LANTERNFISH (MYCTOPHIDAE) IN THE DIET OF THE CAPE PETROL DAPTION CAPENSE AT THE SOUTH SHETLAND AND SOUTH ORKNEY ISLANDS, ANTARCTICA

All of the fish identified in stomach contents and regurgitations of b reeding and chick Cape petrels collected during January and February 1 996 at Fildes Peninsula and Harmony Point, both in the South Shetland Islands and at Laurie Island, South Orkney Islands were myctophids, a family never previously reported in the diet of breeding Cape petrels. Electrona antarctica was the most important fish prey, followed by El ectrona carlsbergi at Fildes Peninsula, Krefftichthys anderssoni at Ha rmony Point and Gymnoscopelus braueri at Laurie Island. The absence of Pleuragramma antarcticum in the diet of this petrel, which is conside red a P. antarcticum-feeder, is discussed.
