ATLAS DEL MAR PATAGÓNICO
spaces linea species

Seabirds, and occasionally marine mammals, follow fishing vessels to take advantage of the catch that is discarded.

Integrated data for: Wandering Albatross, Grey-headed Albatross, Black-browed Albatross, Northern Royal Albatross, Light-mantled Albatross, Southern Giant Petrel, Northern Giant Petrel, White-chinned Petrel, Magellanic Penguin, Southern Rockhopper Penguin, King Penguin, Gentoo Penguin, South American Sea Lion, South American Fur Seal, Antarctic Fur Seal and Southern Elephant Seal.

All available data between January and December were used in the analysis.

Dataholders: J. Arata, D. Boersma, C. Campagna, J. Croxall, M. Fedak, E. Frere, P. Gandini, J. González-Solís, N. Huin, M. Lewis, M.R. Marín, C. Moreno, D.G. Nicholls, R. Phillips, K. Pütz, F. Quintana, A. Raya Rey, G. Robertson, C.J.R. Robertson, A. Schiavini, I. Staniland, D. Thompson, P. Trathan, R. Wilson and P. Yorio.


During the spring and summer, the breeding season for most species, the coastal areas most used by predators are those near the colonies: the north of the Gulf of San Jorge, Peninsula Valdés, Diego Ramirez Islands and Malvinas Islands.

Data on 14 species and 576 trips in spring (October-December).

During the spring and summer, the breeding season for most species, the coastal areas most used by predators are those near the colonies: the north of the Gulf of San Jorge, Peninsula Valdés, Diego Ramirez Islands and Malvinas Islands.

Data on 13 species and 685 trips in summer (January-March).

Dataholders: J. Arata, D. Boersma, C. Campagna, J. Croxall, M. Fedak, E. Frere, P. Gandini, J. González-Solís, N. Huin, M. Lewis, M.R. Marín, C. Moreno, D.G. Nicholls, R. Phillips, K. Pütz, F. Quintana, A. Raya Rey, G. Robertson, C.J.R. Robertson, A. Schiavini, D. Thompson, P. Trathan, R. Wilson and P. Yorio.


Autumn and winter correspond to migratory and long distance foraging trips for most species. The slope front continues to be important, particularly the waters adjacent to the Malvinas Islands, at the latitudes of the San Jorge Gulf and the Río de la Plata, and to the east of the Burdwood Bank.

Data on 14 species and 331 trips in autumn (April-June).

Dataholders: J. Arata, D. Boersma, C. Campagna, J. Croxall, M. Fedak, E. Frere, P. Gandini, J. González-Solís, N. Huin, M. Lewis, M.R. Marín, C. Moreno, D.G. Nicholls, R. Phillips, K. Pütz, F.

All species

Principal feeding areas used by 16 Species of Top Predators:

Coastal areas: the waters adjacent to the Malvinas Islands, Staten Island, Diego Ramírez Islands, Peninsula Valdés and the waters stretching from the south of the peninsula to the north of the Gulf of San Jorge.

Pelagic areas: the slope of the Patagonian Shelf, the ocean environment adjacent to the Malvinas Islands, the shelf-slope area at the latitude of the Gulf of San Jorge, the areas influenced by the outflow of the Río de la Plata, and the area to the east of the Burdwood Bank. The coastal-pelagic corridor between the Valdés Peninsula and the slope is also relevant.

The areas most commonly used by seabirds and marine mammals reveal few seasonal variations, this suggests that the same extensive areas of the ocean are relevant during different periods of the annual cycle of the top predators.

None of the pelagic areas identified as important for top predators is under a regime of special management for the conservation of biodiversity.
