United States President Barack Obama will push forward a plan by three in the central Pacific region into the national protected areas, which will double the area of ​​the world’s marine nature reserve.

June, White House officials announced that they are considering greatly expanding the Pacific remote islands Marine National Protected Areas (PRIMNM), the region covers about 225,000 square kilometers of sea area. Recently, the White House announced that Obama will sign the extension of protected areas announcement to 1.27 million square kilometers, or a sum roughly equivalent to existing nature reserves around the world.

The plan published figures a little bit smaller than the White House news release in June of 1.8 million square kilometers. Obama will take action in accordance with the legal authority, “the National Monuments Act” allows the President to establish a national protected area, and do not have to be approved by Congress.

Conservation organizations welcomed the plan. “This marks the country’s marine protected areas important day.” Pew Charitable Trusts Global Ocean Legacy project leader Matt Rand, said in a statement, “We hope that the pace of the U.S. government is now taking similar behavior will accelerate and promote coastal countries to protect the world’s oceans for more treasures. “Rand support the expansion of protected areas.

Marine researchers predict that by protecting remote and relatively intact ecosystems will benefit from a range of marine organisms in the move. But they noted that for some of the region suffered the worst in terms of the development of fish, related benefits and may take decades to appear after including some tuna species. Moreover, the recovery rate of some of these species depends on how the fish “lazy.”

Typically, rarely fishing in remote waters of new protected areas were covered. There was little fishing boats to and from Hawaii and Johnston eastern Vic nearby coral reefs. More fleet will Howland Island, Baker Island, Pamela Island, Kingman Reef, and Jarvis Island near the tuna-rich waters as a target. But the National Oceanic and Atmospheric Administration (NOAA) figures show that only these waters catches of less than 4% of the total catch volume, the main catch of skipjack and bigeye tuna.

Throughout the life of those protected areas are not far from the tuna species may soon benefit. For example, a recent study revealed that more than 90% of the yellowfin tuna are found living in the waters. The number of yellow fin tuna stocks expected to be approximately 38% of historical levels.

But biologists said that for those who are accustomed to long-distance travel and less time in the new fish in protected areas, the immediate impact of these nature reserves may be more slowing down. John Hampton New Caledonia’s capital Noumea Secretariat of the Pacific Community, Marine Fisheries Project Director, wrote in an e-mail, especially the recent identification of studies have shown that bigeye tuna, “and not long to live here or in the equatorial Pacific Ocean other areas. ” The fish are used to make sushi, the number dropped to only 16% of the historical populations.

However, the researchers said, even in migratory species, protected areas will also help. This is because some fish, like people: some like “travel”, others like “home with.” For bigeye tuna, the lazy, although the proportion of fish unknowable, but “the problem is that some fish will (stay protected areas, and) they can produce more offspring in a longer life.” Vancouver, University of British Columbia fisheries scientist Daniel Pauly said. These lazy fish may also “would not like to travel habits to their offspring, the number of fish that will increase.”

University of Calgary, Canada postdoctoral fish geneticist Jon Mee said that, indeed, the model shows that in many years, nature reserves and even to encourage the evolution of “more lazy” but more healthy fish populations. “We have a lot of evidence to suggest a genetic basis for migratory nature and extent of genetic quite high.” He said. Moreover, if the fish “campaign more, the mortality rate is also higher, which will appear evolution.” Mee development model, compared with those who like to swim around, but also more vulnerable to attack fish, living in protected areas of lazy individuals can have a higher reproductive rate, resulting in even more do not like swimming in groups more big.

French satellite company CLS oceanographer Patrick Lahodey said another long-term benefits of the new protected areas could be brought about to let the fish is no longer vulnerable to the impacts of climate change. Recently published in the “climate change” the journal report, he and his colleagues said that by 2060, the water temperature in the central Pacific Ocean waters where these protected areas will be high enough to attract more Western Pacific bonito. Currently, the fish stocks in the Western Pacific is more dense, and the fishing industry is also more dense.

Oregon State University marine ecologist, NOAA former director (2009 – 2013) Jane Lubchenco noted that these results suggest that the expansion of marine nature reserves did not decline trend. “Before it was severely damaged an area of ​​protection is meaningful. Benefit of this approach is very clear, now is the time for action.” She said.
