Thus, exploitation implies a depletion of secondary production of higher trophic levels (here the production of mass and energy by herbivores and carnivores in the ecosystem) due to the removal of prey. The depletion of secondary production due to the export of biomass and energy through catches was recently formulated as a proxy for evaluating the ecosystem impacts of fishing–i.e., the level of ecosystem overfishing. Here we evaluate the historical and current risk of ecosystem overfishing at a global scale by quantifying the depletion of secondary production using the best available fisheries and ecological data (i.e., catch and primary production). Our results highlight an increasing trend in the number of unsustainable fisheries (i.e., an increase in the risk of ecosystem overfishing) from the 1950s to the 2000s, and illustrate the worldwide geographic expansion of overfishing. These results enable to assess when and where fishing became unsustainable at the ecosystem level. At present, total catch per capita from Large Marine Ecosystems is at least twice the value estimated to ensure fishing at moderate sustainable levels MC was supported financially with a Predoctoral and a postdoctoral fellowship from the Spanish Ministry of Education and Science and additional support by Dalhousie University (Halifax, Canada) Peer reviewed 2008-12-22T10:39:37Z 2008-12-22T10:39:37Z 2008-12-10 artículo http://purl.org/coar/resource_type/c_6501 PLoS ONE 3(12): e3881 1932-6203 http://hdl.handle.net/10261/9313 10.1371/journal.pone.0003881 19066624 en Publisher’s version https://doi.org/10.1371/journal.pone.0003881 open 1453048 bytes application/pdf Public Library of Science
