The main forage organisms for the toothfish were Macrourus whitsoni, fish of the family Channichthyidae, mainly Chionobathyscus dewitti, and squid, including Psychroteuthis glacialis. Fish of the family Nototheniidae, mainly Trematomus loennbergi, were dominant in the toothfish nutrition at SSRU “J” at the shelf in the vicinity of the Ross Ice Shelf. In that area the shrimp Notocrangon antarcticus played an important role in the toothfish nutrition. Cannibalism was not observed for the Antarctic Toothfish. The average points of the stomach contents at various SSRUs correlate positively with the average catches per day. Preys toothfish had length from 8 to 75 cm. Average size of victims was varied but only average size of the ice squid was constant. in different SSRU.
