GONZALEZ ZEVALLOS, Diego et al. Aportes de la ornitología marina a la visión ecosistémica del manejo pesquero. Hornero [online]. 2012, vol.27, n.2, pp.117-126. ISSN 0073-3407.

Contributions of marine ornithology to an ecosystem-based approach to fisheries management At least about 70 species of seabirds feed in the waters of the Argentinean continental shelf, which is probably the area with the highest biomass of albatrosses in the world. The distribution of these birds at sea generally coincides with commercial fisheries in areas with high marine productivity, so their interactions can be frequent and diverse. The study of the Argentine Sea considering seabirds as part of an integrated approach represents a challenge. Some aspects of the biology of these birds could act as environmental indicators to understand systems, assess their conservation status and analyze their relationships with global processes. Although interactions between seabirds and some fishing fleets operating on the Patagonian shelf have not yet been addressed, the knowledge of the ecology, behaviour and conservation of this group of birds has increased significantly in the last decade. Including ecosystem considerations into fisheries management should contribute to long-term food security and ensure effective conservation and sustainable use of the ecosystem and its resources.
