    The diet composition and feeding intensity of mackerel icefish ( Champsocephalus gunnari) around Shag Rocks and the mainland of South Georgia was analyzed from 3,691 stomachs collected in January/February 1994. Main prey items were the amphipod hyperiid Themisto gaudichaudii, mysids (primarily Antarctomysis maxima), and krill (Euphausia superba) in the vicinity of South Georgia and T. gaudichaudii and Thysanoessa sp. around Shag Rocks.
