Resumen:
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.
