ABSTRACT: Analysis of food contents of 784 stomachs was made in 5 species of fishes of the family Nototheniidae: Notothenia coriiceps neglecta. Notothenia rossi marmo-rata, Notothenia nudifrons, Trematomus newnesi and Pleuragramma antarcticum. In the food of the first two of the mentioned species benthic forms predominated and among them Amphipoda were a decidedly preferred component. The composition of the food of N. nudifrons indicates that they feed at the bottom of the sea, the most preferred compo-nent of their diet, however, were pelagic Salpae. T. newnesi and P. antarcticum are characterized by a typically pelagic kind of food. The comparison of food composition and the values of the stomach fullness indices in N. coriiceps neglecta, N. rossi mar-morata and T. newnesi in the summer and winter seasons shows a markedly higher feeding intensity in the summer.
