Abstract

Analysis of food contents of 784 stomachs was made in 5 species of fishes of the family Nototheniidae: Notothenia coriiceps neglecta. Notothenia rossi marmorata, 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 component 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 marmorata and T. newnesi in the summer and winter seasons shows a markedly higher feeding intensity in the summer.
