The age composition ofChionodraco hamatussamples caught by fixed nets in Terra Nova Bay during the Austral summer 1987/88 was determined by examination of thin otolith sections. Individual ages were estimated by counting the number of annuli seen in the sections, since we postulated that annuli were laid down yearly. Fish were estimated to be 5–10 years old. Although our “apparent ages” were not confirmed by other independent estimates, our data seem to compare well with the values reported for other Antarctic fishes. Females in our samples were on average larger than males of the same age and grow somewhat faster, at least over much of the sampled size
