Large -scale protected marine areas successfully protect tensile fish and increase the catch rates.
As Phys.org reported, researchers discovered that we help fish species by protecting expansive ocean areas.
Research scientists analyzed public data to assess the effects of protected ocean areas and published their findings in the magazine Science. They investigated nine large -scale protected marine areas in the Indian and the Pacific.
The results showed that the efforts of the Vang-Per unit of the fisheries of the tuna portion gardens have increased by 12% to 18% near protected areas. However, the increase falls further from the borders.
Even for migrating species such as tuna, protected areas offer overflow benefits that translate into economic profit for fishing.
A few decades ago there was only one large -scale protected marine area in the world, Ecuador's Galápagos Marine Reserve. Now there are more than 20. Many of these waters are in places with tuna fishing, an industry with a value of more than $ 40 billion.

“We discovered that the overflow benefits, measured as the change in catch rates, are the strongest just outside the boundaries of these MPAs and become stronger over time,” says Juan Carlos Villaseñor-Derbez, a professor and the co-author of The report. “The effects were the strongest for the MPAs that fished heavily before protection and are now well immersed.”
This research is important because it emphasizes the recreational and economic benefits of maintaining marine. Tuna fishing benefits from laws in the field of environmental protection, which can help fishing populations thrive and possibly increase the profit by being caught more fish.
Such studies can help to convince special interest groups that the preservation of animals matters and is worth time and investment. The research is a supplement to the biodiversity of the United Nations that go beyond the National Jurisdiction Agreement, an international treaty to maintain the high seas and international goals to protect 30% of the world of the world by 2030.
Although fishing prices go to fisheries, individuals may want to retain even more fish populations by concentrating their diet on vegetable options instead of seafood. You can also support marine habitats by learning and sharing about conservation projects that save fish from extinction and innovations that help revive the decreasing populations.
Sacha Vignieri wrote in the summary of the editor of the study: “Such results clearly underline that MPAs are essential for protecting both species and fishing.”
On a Phys.org Facebook message that sharing the news, an aquarium trainer commented on sport fishermen who often challenge protected areas in the navy: “I hope they feel better about the result now.”
