The IAI supports global change research to provide input to informed decisions for the benefit of societies and its Parties. One the example of such positive interaction is the report of results of IAI project on “SACC: An international consortium for the study of ocean related global and climate changes in South America” (CRN 2076) to authorities of the Argentinean Institute for Fisheries Research and Development (INIDEP) that implementation and effective compliance of protected areas in the Patagonian shelf have benefited the conservation and management of marine resources.
Daniela Alemany, member of the SACC (IAI CRN 2076) summarizes their evaluation of the effects of a large-scale offshore marine protected area (MPA) located on the SW Atlantic Patagonian shelf:
¨We evaluated the effects of a large-scale offshore MPA located on the SW Atlantic Patagonian shelf (43ºS 63ºW) on the demersal fish assemblage. MPA effects were studied employing a five years database collected by a scientific research vessel in protected and fishing locations, before and after the MPA establishment, and fishing effort distribution was studied analyzing extensive databases from the national Vessel Monitoring System, provided by the National Undersecretary of Fisheries. Results show an increasing trend of abundance of the demersal fish assemblage, of abundance of the target and non-target fish species, of hake juvenile size and proportion inside the protected area. Higher fishing pressure in the boundaries of the MPA suggests better catches in their surroundings than in distant areas. This information was reported to INIDEP (National Institute of Fisheries Research and Development), the Argentinean institution that advises on fisheries management to the Federal Fisheries Council. The implementation of this protected area closed to trawling in the Patagonian shelf and its effective compliance benefits the conservation and management of marine resources. This study supports the case for large-scale MPAs in continental shelves.”
