Résumé

A preliminary ecosystem model of the Exclusive Economic Zone of the Kerguelen Islands is presented here. It emphasizes the Sub-Antarctic Patagonian toothfish (Dissostichus eleginoides) fishery zone, monitored since the 1980s by the Museum National d'Histoire Naturelle (Paris, France). The model covers the peninsular shelf of the Kerguelen Islands and their surrounding slopes up to the EEZ limit, which totals a surface area of 575,000 km2. The period treated is between 1987-1988, for which data from a series of oceanographic surveys are available, used as the basis for the estimation of biomasses of the different components of this ecosystem. Data from other sources were used in cases where no survey data is available, notably results of Ecopath models from similar systems, e.g., that of the Weddell Sea.
