Prioritizing ecologically significant and globally important marine conservation areas for vertebrates: synthesizing the best available knowledge to inform management and policy 



Declines in marine predators intensified globally in the 1950’s, as industrial fleets targeted previously inaccessible populations of sharks, tunas, and billfishes. These spatially extensive fisheries continue to expand, while global catches continue to decline.


Given the difficulty of managing these fisheries sustainably, large no-take Marine Protected Areas (MPAs) have been proposed for halting and reversing these declines. These MPAs require knowledge of the critical habitats that maintain these predators and that are relatively immune from the effects of human disturbances. This crucial knowledge is currently severely limited since based primarily on species geographic distributions obtained through fishery catches that remain biased with untargeted species, unfished areas and deliberate underreporting.


Here, PELAGIC planned to overcome this limitation by collecting the most up-to-date and complete information on the biogeography and habitat use of marine mammals, sharks and fishes. Then PELAGIC experts evaluated the current performance of the global system of MPAs for all vertebrates and proposed some options to optimize the design of future MPAs to insure the long-term persistence of vertebrates in the oceans.
