In this study, we present first observations on the feeding behaviour of an Antarctic notothenioid fish, the striped rockcod, Trematomus hansoni Boulenger, 1902. During 13 days of feeding experiment onboard RV Polarstern, the striped rockcod consumed an average of 1.0% BM · day–1 of Loligo reynaudii at the temperature around +1.0°C. The daily food ration of T. hansoni turned out to be lower than predicted by theoretical equations derived for fish living at higher temperatures but was similar to values observed in other Antarctic fish in captivity.
