In this document we inform on the results of six years monitoring changes in the diet of the Blue-eyed Shag Phalacrocorax atriceps as reflected by the analysis of regurgitated pellets collected at two localities of the South Shetland Islands. The comments are mainly focused on Gobionotothen gibberifrons and Notothenia rossii, species of particular interest for CCAMLR. Notothenia rossii appeared in the diet of this bird in the lasts years and the importance of G. gibberifrons fluctuated without trends but, overall, the contribution of these two species to the diet of the Blue-eyed Shag remains low.
