The pike icefish, Champsocephalus esox, is a species of crocodile icefish found at depths of 50–250 m (160–820 ft) in the oceans off Patagonia, the Falklands and rarely South Georgia.[1][2]It is a demersal species that reaches 35 cm (14 in) in length and mainly feeds on fishes and krill.[1] A South Georgian study in 1981 collected a specimen with stomach contents of 90% krill (Euphasia superba) and 10% fish. This species has a whitish body, dark brown caudal fins, and dark brown bars (sometimes forming irregular dark blotches connected with yellowish regions) with no scales except on its lateral line.[2]It is of minor importance to commercial fisheries, with catches in 2008 amounting to a total of 90 tonnes.[3] The fish are trawled from January to March, but none are caught in the winter.[2] It is the only species of crocodile icefish found north of the Antarctic Polar Frontal Zone, with only 3 specimens reported south of the CCALMR area．[2]
