Important study is 1st to predict, through mathematical modelling, that modest increase in the world’s MPAs could swell global seafood yields through spillover. But while the predictions sound good, we have to understand what pulling this off would entail http://www.pnas.org/cgi/doi/10.1073/pnas.2000174117">https://www.pnas.org/cgi/doi/1...
Discuss challenges to expanding global MPA network by 5% to boost yields 20%, particularly need to include productive inshore seas that are fished, not just low hanging fruit of vast remote MPAs in open oceans that account for most coverage @OceanAcademic https://theconversation.com/the-race-for-vast-remote-marine-protected-areas-may-be-a-diversion-64705">https://theconversation.com/the-race-...
Many fishers are sceptical that spillover can boost catches enough to compensate for losing the right to fish within MPAs and tend to strongly oppose proposals to designate more of them https://doi.org/10.1016/j.marpol.2004.10.003">https://doi.org/10.1016/j...

Eg. While 36% of waters around UK covered by MPAs, only 0.0024% has complete ban on all fishing. Increasing number & size of HPMPAs from these 4 small sites to 5% of UK’s sea area would represent more than a 2,000 X increase to which @NFFO_UK would object https://nffo.org.uk/news/industry-unites-to-oppose-benyon-report.html">https://nffo.org.uk/news/indu...
It’s important to stress the political challenges of implementing HPMPAS, but most scientists agree that more MPAs are needed. Scientists are currently pushing to protect 30% of the ocean by 2030 https://www.woi.economist.com/the-need-to-protect-at-least-30-of-the-ocean-by-2030/">https://www.woi.economist.com/the-need-... @CoralReefFish
