All icefish are believed to be piscivorous, but can also feed on krill. [10] Icefish are typically ambush predators; thus, they can survive long periods between feeding, and often consume fish up to 50% of their own body length. Maximum body lengths of 25–50 cm (9.8–19.7 in) have been recorded in these species.
Younger icefish tend to eat krill, and then switch to mackerel icefish when they grow (about 30 cm). From data collected in different locations, researchers have determined that the blackfin icefish likely feeds sporadically, consuming large quantities of fish and krill at a time, but at irregular intervals.

Jonah's icefish mainly feeds on fish, such as Dacodraco hunteri, Chaenodraco wilsoni, Pleuragramma antarcticum and Chionodraco sp., as well as krill, as adults. Young specimens, however, feed mainly on krill, especially Euphausia superba , and they are frequently caught along with their prey at 10 to 15 cm (3.9 to 5.9 in) total length.
Cryodraco antarcticus feeds on fishes and krill (studies from 1982 to 1984 revealed mostly fishes and Antarctic krill). The larvae have a long late winter pelagic phase. [1] It is closely related to the blackfin icefish (Chaenocephalus aceratus) but differs in a number of meristic characteristics. They are similar in size, colouration and body ...
Chionodraco icefishes are predatory, feeding on other fish species and on krill. They have a long post larval pelagic phase. [3] In common with many other channichthyid fishes, reproduction in Chionodraco hamatus involves laying eggs in a nest and parental guarding.
However, healthy people can generally eat raw fish safely if it is sushi grade, sourced from reputable suppliers and handled properly to prevent contamination. Moreover, certain fish, like salmon ...

The ocellated icefish (Chionodraco rastrospinosus) is a fish of the family Channichthyidae. [3] [4] It lives in the cold waters off Antarctica and is known for having transparent haemoglobin-free blood. [5] [6] C. rastrospinosus live in the Southern Ocean up to a depth of 1 km. They are most commonly found on the seabed at 200–400 m.
