Abstract:
Biology And The Predator-Prey Relationships Between Seabirds And Seals And
Antarctic Fish; Identification Of Parameters To Detect Changes In The Ecosystem
Instituto Antartico Argentino (IAA) Project No. 29 2002-2004
The aim of the project is to study the biology and the predator-prey
relationships between seabirds and seals and Antarctic fish to identify
parameters that serve as indicators of
... changes in the ecosystem. The target
species of the project are the Antarctic Shag Phalacrocorax bransfieldensis,
the Antarctic Tern Sterna vittata, the Weddell Seal Leptonichotes weddelli, the
Antarctic fur Seal Arctocephalus gazella and different benthic-demersal and
pelagic Antarctic fish. One of the main achievements of the project was to
develop a methodology to monitor changes in coastal fish populations through
the analysis of the diet of the Antarctic Shag. This methodology was adopted as
a "Standard Method" by the Commission for the Conservation of Antarctic Marine
Living Resources (CCAMLR).
