Estimating the biodiversity of the sub-Antarctic Indian part for the ecoregionalisation of CCAMLR areas 58.5.1 and 58.6: Part II. foraging habitats of top predators from French Antarctic Territories – areas of ecological significance in the Southern Ocean

Preliminary analysis of long term dataset on individual tracking of 19 species of seabirds and seals breeding in the French Southern Territories (Crozet, Kerguelen and Amsterdam Islands) to identify area of importance for conservation in the Southern Ocean.
The preliminary results on locations data show that top predators are largely distributed on the southern part of the Indian Ocean from the tropics to the Antarctica. They overlap with numerous Exclusive Economic Zones (belonging to France, Australia, South Africa, Namibia and New Zealand) and high sea waters covered by six RFMOs (CCAMLR, Indian Ocean Tuna Commission-IOTC, Commission for the Conservation of Southern Bluefin Tuna-CCSBT, Southern Indian Ocean Fisheries Agreement-SIOFA, International Commission for the Conservation of Atlantic Tunas-ICCAT, South East Atlantic Fisheries Organization-SEAFO) suggesting the importance of collaboration for the conservation of top predators.
