Nereus members Guillermo Ortuño Crespo, Daniel Dunn, and Patrick Halpin are co-authors on a new paper published in the journal Nature Ecology & Evolution, ‘High-seas fish biodiversity is slipping through the governance net’. They stress the need to include fish biodiversity in negotiations for the new BBNJ treaty at the United Nations General Assembly and close current legal gaps in existing ocean governance frameworks.

By Guillermo Ortuño Crespo, Nereus Program Fellow at Duke University

Due to their wide-ranging swimming behaviors, migratory fish, marine mammal, seabird and sea turtle species experience a variety, and an increasing amount, of anthropogenic pressures over the course of their lives. These threats, including climate change, overfishing, and marine pollution, combined with conservation strategies that largely fail to consider spatial connectivity over the life cycle, are resulting in declining populations worldwide.

M.Sc, Ecosystem-based Management of Marine Systems

Duke University

Guillermo Ortuño Crespo is a Ph.D. student at Duke University’s Marine Geospatial Ecology Lab. He recently obtained a M.Sc. degree in Ecosystem-based Management of Marine Systems from the University of St Andrews, where his research was focused on the conservation and management of Thunnus thynnus and the use of genetic tools in fisheries management. His main research interests are in the spatial ecology and conservation of highly migratory, straddling species, which raise fundamental questions about their trans-boundary management, particularly in areas beyond national jurisdiction.View More
