A new study<\/a> published in Science Advances<\/em> today provides evidence that large-scale, offshore, and fully-protected marine areas (MPAs) protect biodiversity without negatively impacting fishing and food security. <\/p>\n

In the first-ever \u201cbefore and after\u201d assessment of the impact of establishing Mexico\u2019s Revillagigedo National Park on the fishing industry, a team of US and Mexican researchers found that Mexico\u2019s industrial fishing sector did not incur economic losses five years after the park\u2019s creation despite a full ban on fishing activity within the MPA. <\/p>\n

Established in 2017, the \u201cGal\u00e1pagos of Mexico\u201d is the world\u2019s 13th-largest MPA, and one of the few where all damaging human activities, including fishing, are banned to help marine populations recover. Home to one of the world\u2019s largest aggregations of sharks and manta rays, as well as tuna, humpback whales and five species of sea turtles, it also shelters more than 300 species of fish, of which 36 are not found anywhere else in the ocean. At the time, the Mexican industrial fishing lobby opposed the creation of the National Park, arguing that it would impact their catches and increase their costs.<\/p>\n

\u201cWorldwide, the fishing industry has blocked the establishment of the marine protected areas we urgently need to reverse the human-caused global depletion of sea life. This study uses satellite tracking of fishing vessels and artificial intelligence (AI) to show that the fishing industry\u2019s concerns are unfounded,\u201d said Enric Sala, Explorer in Residence at National Geographic Society, the founder of Pristine Seas and a study co-author. \u201cEven the largest of MPAs, which safeguard entire ecosystems, home to thousands of species of marine creatures, do not impact the handful of fish species that the fishing industry seeks out. The larger the MPA, the larger the benefits.\u201d<\/p>\n

Methodology<\/strong><\/p>\n

The study, conducted by a team of researchers from the Mexican Center for Marine Biodiversity, UC San Diego\u2019s Scripps Institution of Oceanography, the Institute of Americas\u2019 Gulf of California Marine Program, and the National Geographic Society, analyzes the behavior and productivity of the Mexican industrial fishing sector before and five years after the implementation of the largest fully protected MPA in North America, the Revillagigedo National Park.<\/p>\n

Using data from satellite tracking, fish catches from the Mexican Fisheries Commission, and new AI tools from the Allen Institute for AI\u2019s Skylight platform, the experts set out to determine whether the creation of the MPA reduced fishing within the protected area, whether fishing catches were affected and if the creation of the MPA displaced fishing onto a larger area, resulting in an overall negative impact on marine biodiversity. <\/p>\n

\u201cThe use of satellite tracking devices and AI monitoring platforms was critical to show compliance from the fishing industry and for the MPA managers\u2019 to monitor the protected area,\u201d said Dr. Fabio Favoretto, postdoctoral scholar at Scripps Institution of Oceanography and lead author of the study.<\/p>\n

The satellite data analyzed by Favoretto came from government-mandated GPS devices installed on some 2,000 fishing vessels. By reviewing the open source data, they were able to identify movement of fishing vessels to see if fishing behaviors or maneuvers were performed. The team then employed machine-learning enabled techniques to identify patterns associated with vessels.<\/p>\n

They found that the Revillagigedo National Park has had no negative effect on the Mexican industrial fleet\u2019s catches, nor did it increase the area used for fishing that would drive fishing vessels to venture further to catch fish. Skylight revealed only a few isolated cases of illegal fishing within the MPA after 2017, highlighting the effectiveness of technology in helping those monitoring and protecting the 147,000 square kilometers of waters included within the park\u2019s boundary. <\/p>\n

The study results refute the Mexican fishing industry’s argument that the park would cause a potential loss of 20% of their tuna and other pelagic catches and provide proof that large, fully-protected MPAs can contribute to a more sustainable and equitable use of the ocean, without major economic repercussions on the fishing industry. <\/p>\n

\u201cThe findings of this study are consistent with what experts have recorded in other Pacific marine protected areas,\u201d said Octavio Aburto, co-author and professor of marine biology at Scripps Institution of Oceanography. \u201cAny argument to the contrary were just assumptions \u2014 this study provides the data to show that negative impacts to fishing do not exist. We hope the results can open a discussion to work together with the fishing industry to protect biodiversity and improve fish stocks.\u201d <\/p>\n

Safeguarding Biodiversity<\/strong><\/p>\n

The findings are released at a time when countries debate how to implement the global goal to protect and conserve at least 30% of the ocean by 2030, which is enshrined in a landmark agreement reached at the UN Global Biodiversity Conference (COP15) in December 2022. Just last month, United Nations members agreed on a legally-binding instrument to protect biodiversity in the high seas \u2014 the international waters beyond national jurisdictions. <\/p>\n

\u201cThe clock is ticking until 2030,\u201d Sala said. \u201cIf the world is serious about protecting the natural world \u2014 our life support system \u2014 we need to drastically increase ocean protection. Right now, less than 8% of the ocean is somewhat protected, and only 3% is fully protected from fishing and other damaging activities. Millions of species, including humans, who rely on the ocean for oxygen, food, mitigation of global warming, medicine and more depend on us to act.\u201d<\/p>\n

Threatened by human activities like overfishing, the ocean\u2019s rich stockpile of biodiversity is rapidly declining, posing risks to food security, health and the environment. By rapidly establishing marine protected areas in strategic ocean areas, the world can collectively safeguard more than 80%<\/u><\/a> of the habitats of endangered species, up from a current coverage of less than 2%.<\/p>\n

Amid these debates, the study provides empirical evidence that large-scale MPAs in countries\u2019 Exclusive Economic Zones can contribute to global conservation goals without compromising fisheries\u2019 interests or a nation\u2019s ability to ensure food security.<\/p>\n

Shoring up the Fishing Industry<\/strong><\/p>\n

The study refutes a long-held view promoted by the industrial fishing lobby that ocean protection harms fisheries, and opens up new opportunities to revive the industry just as it is suffering from a recession due to overfishing and the impacts of global warming.<\/p>\n

\u201cSome argue that closing areas to fishing hurts fishing interests. But the worst enemy of fishing is overfishing and bad management \u2014 not protected areas,\u201d Dr. Sala said. <\/p>\n

The study will enrich ongoing discussions taking place in Mexico and beyond as Catalina L\u00f3pez-Sag\u00e1stegui, co-author and a researcher at the Institute of Americas, said: \u201cAccess to data and technology is improving our collective understanding of marine ecosystems health, which allows us to design and implement MPAs that help restore the health and resilience of marine ecosystems, benefiting fisheries in the long term.\u201d<\/p>\n

Dr. Reniel Cabral, Senior Lecturer at James Cook University in Australia, who wasn\u2019t involved in this study, added: \u201cIt\u2019s simple: When overfishing and other damaging activities cease, marine life bounces back. After protections are put in place, the diversity and abundance of marine life increase over time, with measurable recovery occurring in as little as three years. Target species and large predators come back, and entire ecosystems are restored within MPAs. With time, the ocean can heal itself and again provide services to humankind.\u201d  <\/p>\n

Dr. Sala said: \u201cMPAs are the most effective tool we have for protecting the health and diversity of our oceans. We need to expand and strengthen protected areas to ensure that our oceans can continue to provide food, jobs and other vital benefits for future generations. Our study helps to dispel the myth put forward by the industrial fishing lobby that MPAs harm them.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
