As part of a program aimed to understand on the relationships between fish and their predators, from 1990 the Instituto Antártico Argentino is developing studies on the diet of the Antarctic Shag Phalacrocorax bransfieldensis. Our studies started and currently continue at Duthoit Point (62º19´S, 58º51´W), Nelson Island, South Shetland Islands (Casaux & Barrera-Oro, 1993a; Casaux et al., 1995a; Coria et al., 1995; Favero et al., 1998), but from 1991 were extended to other localities of this archipelago such as Bajas Rocks (62º14´S, 58º40´W) (Casaux et al., 1995b), Half Moon Island (62º36´S, 59º54´W) (Casaux & Barrera-Oro, 1995a; Barrera-Oro & Casaux, 1996) and Harmony Point (62º17´S, 59º14´W) (Casaux, 1997), of the Laurie Island, South Orkney Islands such as Pirie Peninsula (Casaux et al., 1997) and of the Antarctic Peninsula such as Danco Coast.
