    The significant similarity of Kerguelen and South Georgia icefish Ch.gunnari populations ecology has been revealed. Fish of all lengths and ages are planktonphages. Fish of the first two age groups have been continuously found in the pelagic layer off South Georgia and Kerguelen-Heard. Immature fish also partially distribute in the pelagic layer both in the daytime and at night. Mature fish, as a rule, are at the bottom in the daytime, however in some years they like immature fish, have been caught with pelagic fishing gear in the water column during the daytime.
