Study of Biology and Predator-Prey Relationships. IAA Project No. 29 2002-2004

Project Description
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).
