PELAGIC

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

 

PELAGIC

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 overcame this limitation by collecting the most up-to-date and complete information on the biogeography and habitat use of marine mammals, sharks and fishes. In particular, PELAGIC was able to :

  • show that the body size and abundance of sharks are strongly correlated with the distance to anthropogenic pressures and in particular the distance to fishing ports;
  • highlight the need to establish new strategies for MPAs, taking into account the preferential habitats of marine predators, which are essential for maintaining biodiversity in our oceans and the functioning of oceanic systems.

 

The researchers also identified specific areas that, if protected, would safeguard over 80% of the habitats for endangered marine species, and increase fishing catches by more than eight million metric tons. These results, published in Nature in 2021 show that a targeted strict ocean protection can contribute to a more abundant supply of healthy seafood and provide a cheap, natural solution to address climate change—in addition to protecting embattled species and habitats.
