(02/21/2014) In a move signaling their commitment to CITES agreements on international trade of plants and animals, the Indonesian government declared two species of manta ray 'protected' under Indonesian law. Decree Number 4/KEPMEN-KP/2014 issued by Ministry of Maritime Affairs and Fisheries states that two manta ray species, Manta birostris and Manta alfredi, now enjoy full protection throughout their entire life cycle. The decree explicitly extends that protection to all parts of their body.
35 pictures of the sharkfin trade that will shock and dismay you
(02/07/2014) Last month scientists released a study warning that one quarter of all sharks and rays are threatened with extinction. The research was the result of collaboration between 300 scientists from 64 countries. It concluded that overfishing is the biggest threat to the most number of species, noting that up to 73 million sharks are killed each year for their fins alone.
One quarter of sharks and rays threatened with extinction
(01/22/2014) One quarter of all shark and ray species are threatened with extinction, according to a new study published in the open-access journal eLife. The paper analyzed the threat and conservation status of 1,041 species of chondrichthyans—the class of fish whose skeletons are made of cartilage instead of bone which includes sharks, rays, skates and chimaeras—and found this group to be among the most threatened animals in the world.
Indonesia’s national airline carrier bans shark fins
(11/23/2013) Indonesia’s national carrier Garuda Indonesia has joined a growing number of airlines looking to curb the international shark fin trade by banning the transport of shark fins and other shark products on their aircraft. The airline had previously transported 36 tons of shark fin products a year, the conservation group said in a media release on Nov. 15.
Fishermen get crafty to circumvent shark fin ban
(11/10/2013) Authorities in Costa Rica have identified a new method used by fishermen to circumvent a ban on killing sharks for their fins. According to an INTERPOL alert, fishermen are now leaving a band of skin to keep the fin attached to the spine when they kill sharks. This approach takes advantage of an apparent loophole in regulations governing the shark fin trade.
The 'dead' ocean: eyewitness says overfishing has emptied the Pacific
(10/22/2013) An Australian sailor has described parts of the Pacific Ocean as "dead" because of severe overfishing, with his vessel having to repeatedly swerve debris for thousands of kilometers on a journey from Australia to Japan. Ivan MacFadyen told of his horror at the severe lack of marine life and copious amounts of rubbish witnessed on a yacht race between Melbourne and Osaka. He recently returned from the trip, which he previously completed 10 years ago.
Shark overfishing hurts coral reefs
(09/20/2013) Overfishing for sharks is having detrimental effects on coral reefs, finds a new study published in the journal PLOS One.
Mesoamerican Reef needs more local support, says report
(09/13/2013) From massive hotel development through the agriculture industry, humans are destroying the second largest barrier reef in the world: the Mesoamerican Reef. Although global climate change and its effects on reefs via warming and acidification of coastal waters have made recent headlines, local human activities may destroy certain ecosystems before climate change has a chance to do it. The harmful effects of mining, agriculture, commercial development, and fishing in coastal regions have already damaged more than two-thirds of reefs across the Caribbean, in addition to worsening the negative effects of climate change.
Forgotten species: the arapaima or 'dinosaur fish'
(07/15/2013) Let's go back some 14,000 years (or up to 50,000 depending on who you talk to), since this is the first time humans encountered the meandering, seemingly endless river system of the Amazon. Certainly, the world's first Amazonians would have been astounded by the giant beasts of the region, including ground sloths and mastodons (both now extinct), as well as giant anteaters, armadillos, and tapirs, currently the biggest land animal on the continent. But these first explorers might have been even more surprised by what dwelled in the rivers: anaconda, caiman, and the arapaima. Wait, the what?
Yangtze finless porpoise drops to Critically Endangered
(07/07/2013) The newest update to the IUCN Red List has downgraded the status of the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) from Endangered to Critically Endangered, reflecting the deteriorating state of arguably the world's most degraded river system. The downgrade follows a survey last year that counted only 1,000 animals, a 50 percent decline from 2006.
San Francisco seafood restaurants go sustainable
(07/02/2013) The Seafood Watch Program, first created by Monterey Bay Aquarium in the late 1990s, is arguably the best-known guide to sustainably-caught seafood in the U.S. Listing seafood choices in three categories—green (best choices), yellow (good alternatives), and red (avoid)—the guide informs consumers of the best options. However, it's one thing to create a well-respected guide, and another issues altogether to get producers and consumers to use it. But a newer partnership, the San Francisco Seafood Watch Alliance, is working to bridge this gap. Maggie Ostdahl of Aquarium of the Bay works with the Seafood Watch Restaurant program and restaurants across San Francisco—one of the best places in the country for seafood—to source sustainable seafood. Restaurant partners avoid seafood on the guide's red list.
Poisonous jellyfish on the rise in the Mediterranean
(06/11/2013) Scientists across the Mediterranean say a surge in the number of jellyfish this year threatens not just the biodiversity of one of the world's most overfished seas but also the health of tens of thousands of summer tourists.
Conserving the long-neglected freshwater fish of Borneo
(06/11/2013) Borneo is a vast tropical island known for orangutans, rhinos, elephants, sun bears, proboscis monkeys, hornbills, and ubiquitous leeches. Conservationists have championed all of these species (aside from the leeches) in one way or another, but like many tropical regions Borneo's freshwater species have long been neglected, despite their rich biodiversity and importance to local people. But a new organization, the Kinabatangan River Spirit Initiative, is working to change that.
Monster shark sparks talk of overfishing
(06/06/2013) A giant mako shark caught by a sports-fisherman Monday in California has spurred a conversation about declining shark populations worldwide, reports the Associated Press.
Manta ray tourism worth 28 times more than killing them for Traditional Chinese Medicine
(06/03/2013) A new study in the open access journal PLoS ONE estimates that manta rays are worth $140 million a year in tourism across 23 countries, significantly outweighing the worth of manta ray gill plates, which have become the newest craze in Traditional Chinese Medicine.
Famed bird reappears after 400,000 miles of flight
(05/22/2013) A migratory shorebird that has flown more than 400,000 miles has reappeared once again.
Biosphere conservation: monumental action is critical to avert global environmental crisis
(05/20/2013) Human-caused changes to our biosphere—the global total of the world's ecosystems—are now so great and alarmingly rapid that human lives and societies undoubtedly face epic challenges in the near future as our biosphere deteriorates, planetary boundaries are reached, and tipping points exceeded. We may survive, we may painfully adapt, but it is a fair bet that grave hardship, loss, and sacrifice lay ahead. The nature and extent of impacts among human populations hinges on how successfully we respond to the biosphere crisis with extraordinary leadership, balanced solutions applied at global scales, and unprecedented cooperation—or not.
Industrialized fishing has forced seabirds to change what they eat
(05/14/2013) The bleached bones of seabirds are telling us a new story about the far-reaching impacts of industrial fisheries on today's oceans. Looking at the isotopes of 250 bones from Hawaiian petrels (Pterodroma sandwichensis), scientists have been able to reconstruct the birds' diets over the last 3,000 years. They found an unmistakable shift from big prey to small prey around 100 years ago, just when large, modern fisheries started scooping up fish at never before seen rates. The dietary shift shows that modern fisheries upended predator and prey relationships even in the ocean ocean and have possibly played a role in the decline of some seabirds.
What if companies actually had to compensate society for environmental destruction?
(04/29/2013) The environment is a public good. We all share and depend on clean water, a stable atmosphere, and abundant biodiversity for survival, not to mention health and societal well-being. But under our current global economy, industries can often destroy and pollute the environment—degrading public health and communities—without paying adequate compensation to the public good. Economists call this process "externalizing costs," i.e. the cost of environmental degradation in many cases is borne by society, instead of the companies that cause it. A new report from TEEB (The Economics of Ecosystems and Biodiversity), conducted by Trucost, highlights the scale of the problem: unpriced natural capital (i.e. that which is not taken into account by the global market) was worth $7.3 trillion in 2009, equal to 13 percent of that year's global economic output.
China 'looting' Africa of its fish
(04/24/2013) Just 9% of the millions of tonnes of fish caught by China's giant fishing fleet in African and other international waters is officially reported to the UN, say researchers using a new way to estimate the size and value of catches. Fisheries experts have long considered that the catches reported by China to the UN's Food and Agriculture Organization (UNFAO) are low but the scale of the possible deception shocked the authors.
The river of plenty: uncovering the secrets of the amazing Mekong
(04/23/2013) Home to giant catfish and stingrays, feeding over 60 million people, and with the largest abundance of freshwater fish in the world, the Mekong River, and its numerous tributaries, brings food, culture, and life to much of Southeast Asia. Despite this, little is known about the biodiversity and ecosystems of the Mekong, which is second only to the Amazon in terms of freshwater biodiversity. Meanwhile, the river is facing an existential crisis in the form of 77 proposed dams, while population growth, pollution, and development further imperil this understudied, but vast, ecosystem.
Yangtze porpoise down to 1,000 animals as world's most degraded river may soon claim another extinction
(04/16/2013) A survey late last year found that the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) population has been cut in half in just six years. During a 44-day survey, experts estimated 1,000 river porpoises inhabited the river and adjoining lakes, down from around 2,000 in 2006. The ecology of China's Yangtze River has been decimated the Three Gorges Dam, ship traffic, pollution, electrofishing, and overfishing, making it arguably the world's most degraded major river. These environmental tolls have already led to the likely extinction of the Yangtze river dolphin (Lipotes vexillifer), or baiji, and possibly the Chinese paddlefish (Psephurus gladius), which is one of the world's longest freshwater fish.
Breaking the mold: Divya Karnad takes on fisheries and science journalism in India
(04/15/2013) Fishing is not a woman's domain in most countries across the globe. In parts of India there are fishing communities who believe that having a woman onboard a fishing boat brings bad luck. Despite this, Divya Karnad, a scientist who studies marine life in India, has spent several years studying fisheries and their impact on species like sharks and sea turtles. Her work forms a part of global efforts to track declining marine species and encourage more sustainable fishing.
Sharks and rays win protections at CITES
(03/11/2013) Today, for the first time, sharks and rays have won the vote for better protection under CITES (the Convention on International Trade in Endangered Species), the world's regulating body on trade in threatened species. Five shark species and manta rays, which includes two species, have received enough votes to be listed under Appendix II of CITES, which means tougher regulations, but not an outright ban. However, the votes could still be overturned before the end of the meeting.
Has shark fin consumption peaked at 100M dead sharks per year?
(03/05/2013) While a new study warns that up to 100M sharks are killed annually, there are signs out of China that demand for shark fin may be on the decline. A study published last week in the journal Marine Policy estimated shark deaths at 100 million in 2000 and 97 million in 2010, suggesting a slight drop in shark killing. Meanwhile reports out of China in recent months suggest an accelerating decline in shark fin consumption. China is the top market for shark fin, which is consumed as a status symbol, typically at wedding ceremonies and business dinners.
Amazon river ecosystems being rapidly degraded, but remain neglected by conservation efforts
(02/08/2013) The world's largest river system is being rapidly degraded and imperiled by dams, mining, overfishing, and deforestation, warns a study published last week by an international team of scientists.
Saving manta rays from the fin trade
(01/15/2013) Tens of millions of sharks and rays are killed each year to meet demand for shark fin, a delicacy across East Asia. But while the plight of sharks has gained prominence in international environmental circles in recent years, the decline in rays has received considerably less attention. A new film, Manta Ray of Hope, aims to change that. Produced by cinematographer, scuba diver, and marine conservationist Shawn Heinrichs, Manta Ray of Hope offers a look at the mysterious and magnificent world of the world's largest ray, the manta ray. The film highlights both the threats mantas face as well as some of the people who are working to save them.
Paradigm shift needed to avert global environmental collapse, according to author of new book The Blueprint: Averting Global Collapse
(01/10/2013) Global strategist, trained educator, and international lecturer Daniel Rirdan set out to create a plan addressing the future of our planet. His book The Blueprint: Averting Global Collapse, published this year, does just that. "It has been a sixty hour a week routine," Rirdan told mongabay.com in a recent interview. "Basically, I would wake up with the burden of the world on my shoulders and go to sleep with it. It went on like this for eighteen months." It becomes apparent when reading The Blueprint that it was indeed a monumental undertaking.

(01/05/2013) A bluefin tuna sold for a record $1.76 million at an auction in Tokyo, Japan Saturday, reports the Associated Press.
Jeff Corwin talks sharks
(12/04/2012) Sharks are among the most feared of all the world's predators, yet humans kill tens of millions of sharks for every person who falls victim to shark attack. Part of our fear stems from lack of understanding. A new eBook however tries to change that. Jeff Corwin, an Emmy Award Winning TV host, has this week released Jeff's Explorer Series: SHARKS, the first of a new eBook series, which Corwin likens to the 21st century version of an encyclopedia. The eBook is rich with video, images, and text. It is narrated by Corwin.
Pledge to end wildlife trafficking for Wildlife Conservation Day
(12/04/2012) Today has been dubbed the first ever global Wildlife Conservation Day. To honor it, a coalition of conservation groups—including WWF and Wildlife Conservation Society (WCS)—are working to raise awareness of illegal wildlife trafficking. Poaching for traditional medicine, bushmeat, and other products has put innumerable species at risk, including tigers, rhinos, sharks, and elephants.
Could rebuilding global fisheries save hundreds of billions of dollars?
(11/26/2012) Global fisheries are gutting the world economy by US$13 billion annually, according to an economic analysis published July 13 in the journal PLoS ONE. National subsidies that encourage overfishing cause the most losses, the analysis claims. However, researchers believe that allowing fish stocks to rebuild and making fishing more efficient could reverse these losses, leading to net gains of US$600 to US$1,400 billion within 50 years. Such savings won’t come cheaply, the analysis suggests. Rebuilding fisheries worldwide could cost US$130 to US$292 billion, the researchers estimate. Most of the cost would go toward retraining or retiring nearly half of the world’s 35 million fisheries workers.
Controversial dam gets approval in Laos
(11/07/2012) Laos has given approval to the hugely-controversial $3.5 billion Xayaburi Dam on the Mekong River, reports the BBC. The massive dam, which would provide 95 percent of its energy production to Thailand, has been criticized for anticipated impacts on the river's fish populations, on which many locals depend.
Above the ocean: saving the world's most threatened birds
(11/01/2012) A life on the ocean is a perilous one for any bird. They must expend energy staying aloft for thousands of miles and learn to be marathon swimmers; they must seek food beneath treacherous waves and brave the world's most extreme climates; they must navigate the perils both of an unforgiving sea and far-flung islands. Yet seabirds, which includes 346 global species that depend on marine ecosystems, have evolved numerous strategies and complex life histories to deal with the challenges of the sea successfully, and they have been doing so since the dinosaur’s last stand. Today, despite such a track record, no other bird family is more threatened; yet it's not the wild, unpredictable sea that endangers them, but pervasive human impacts.
Penguins face a slippery future
(09/26/2012) Penguins have spent years fooling us. With their image seemingly every where we turn—entertaining us in animated films, awing us in documentaries, and winking at us in commercials—they have made most of us believe they are doing just fine; the penguin's charming demeanor has lulled us into complacency about their fate. But penguin populations are facing historic declines even as their popularity in human society rises. Overfishing is decimating some of their prey species, climate change is shifting their resources and imperiling their habitat, meanwhile pollution, such as oil spills, are putting even healthy colonies at risk. Now, a young organization, the Global Penguin Society (GPS), is working to save all of the world's 18 penguin species by working with scientists, governments, and local communities.
Illegal lobster fishermen slammed with over $50 million penalty
(08/21/2012) Three men who illegally harvested lobster from South African waters and smuggled them to the U.S. for 14 years have been ordered to pay $54.9 million in restitution to the South African government by a District Court in Manhattan. According to the Pew Environment Group this is the largest restitution order under the U.S. Lacey Act, which deals with the illegal wildlife trade. The judgement, however, still requires the approval of a district judge.
'Time pollution': loss of predators pushes nocturnal fish to take advantage of the day
(06/25/2012) Nocturnal fish—which sport big eyes for improved night vision—are taking back the day in the coral reefs of the Tabuaeran Atoll, according to a new study in the open-access journal PLoS ONE. Overfishing has plundered the Pacific atoll of many of its notable predators, including sharks and barracudas, causing ripple effects through the ecosystem. One of these emerging changes appears to be that with less fear of being eaten, nocturnal fish are increasingly venturing out during the day.
World failing to meet promises on the oceans
(06/14/2012) Despite a slew of past pledges and agreements, the world's governments have made little to no progress on improving management and conservation in the oceans, according to a new paper in Science. The paper is released just as the world leaders are descending on Rio de Janeiro for Rio+20, or the UN Summit on Sustainable Development, where one of the most watched issues is expected to be ocean policy, in part because the summit is expected to make little headway on other global environmental issues such as climate change and deforestation. But the new Science paper warns that past pledges on marine conservation have moved too slowly or stagnated entirely.
Australia sets aside 40 percent of its waters for protection
(06/14/2012) In an announcement to coincide with the beginnings of the UN's Rio+20 Summit on Sustainable Development, Australia has announced ambitious plans to protect 3.1 million square kilometers (1.19 million square miles) of its ocean, including the Coral Sea. If enacted, the proposition will increase Australia's marine protected areas from 27 to 60, covering about 40 percent of Australia's waters.
B95, the great survivor
(06/11/2012) He is so long-lived that he has surpassed all expectations, touching hearts throughout the American continent, bringing together scientists and schools, inspiring a play and now even his own biography. B95 is the name of a rufus red knot (Calidris canutus rufus), a migratory bird that in his annual journeys of 16,000 kilometers (9,940 miles) each way from the Canadian Arctic to Tierra del Fuego, in Argentina, has flown a distance bigger than the one between the Earth and Moon.
Regulations help fish, and fishermen, recover in the U.S.
(05/30/2012) Marine fish populations in the U.S. are generally recovering, according to a new report by the National Oceanic and Atmospheric Administration (NOAA). Last year six fish populations reached healthy levels in the U.S., boosting the total number of fish populations that have recovered to 27 since 2000. The success is due to the implementation of science-based annual catch limits which regulate how many fish are caught every year.
Educating the next generation of conservation leaders in Colombia
(05/14/2012) Colombia's northern departments of Cordoba and Bolivar are home to an abundance of coral reefs, estuaries, mangroves forests, and forests. Rich in both marine and terrestrial wildlife, local communities depend on the sea and land for survival, yet these ecosystems are imperiled by booming populations, overexploitation, and unsustainable management. Since 2007, an innovative education program in the region, the Guardians of Nature, has worked to teach local children about the ecology of the region, hoping to instill a conservation ethic that will aid both the present and the future.
Featured video: the oceans and Rio+20
(05/10/2012) A new video by Pew Environment Group and the Zoological Society of London (ZSL) hopes to convince policy-makers attending the Rio+20 Summit on Sustainable Development this summer that urgent action is needed to save the ocean's from an environmental crisis.
Featured video: Google Earth highlights imperiled coral reefs around the world
(04/18/2012) A new video by Google Earth and the World Resources Institute (WRI) highlights the world's many endangered coral reefs. A part of the WRI's Reefs at Risk program, the video highlights regional and global threats to the oceans' most biodiverse ecosystem. According to the WRI, a stunning 75 percent of the world's reefs are currently threatened.
Whole Foods bans 'red' fish from its stores
(04/10/2012) Whole Foods has announced it will be the first grocery chain in the U.S. to no longer sell any seafood in the "red." Based on sustainability ratings by the Monterey Bay Aquarium and Blue Ocean Institute, fish labeled red are those that are considered either overfished or fished in a manner that impacts other species or damages marine ecosystems. Beginning Earth Day, April 22nd, Whole Foods will no longer be selling Atlantic halibut, grey sole, skate, octopus, tautog, sturgeon, among others. Already, the store doesn't sell some unsustainable catches such as bluefin tuna and orange roughy.
Three U.S. retailers pledge to avoid fish from embattled Ross Sea
(03/14/2012) The Ross Sea, a massive bay off Antarctica, has been dubbed the world's last ocean due to its pristine state, long-untouched by industry and fisheries. However, over the last 15 years New Zealand commercial fisheries have entered the sea, seeking the slow-growing Antarctic toothfish which is usually sold as the high-end Chilean sea bass. Now as conservation groups plead for nations to grant the Ross Sea protected status, Greenpeace has begun a campaign to get good retailers to steer clear of stocking Antarctic toothfish. To date, Safeway, Wegmans, and Harris Teeter has all pledged not to source from the Ross Sea.
Camera traps go under the ocean, seeking sharks
(03/12/2012) Remote camera traps, which have become a hugely important conservation tool on land during the past decade, have now gone underwater. Marine biologists have used underwater video camera traps to compare the population of Caribbean reef sharks (Carcharhinus perezii) in Belize's protected areas versus fishing areas in a new study in the open-access journal PLoS ONE. Conducted from 2005-2010, the study found that reef sharks benefited significantly from conservation areas.
Sawfish impale, cleave prey with snout
(03/05/2012) Although all seven species of sawfish are nearly extinct, scientists have spent little time studying these vanishing species. However that is changing as a new study in Current Biology sheds light on the sawfishes' most distinguishing feature: its long toothed snout, which gives the fish its name. "I was surprised to see how skilled sawfish are with their saw," said co-author Barbara Wueringer of the University of Queensland in a press release. "They use their saw to impale prey on the rostral teeth by producing several lateral swipes per second."
Paleontologists reconstruct extinct, "elegant" penguin
(02/27/2012) Around 25 million years ago a penguin with a long, sharp beak and massive flippers lived in a New Zealand that was almost entirely underwater. The bird, named Kairuku after a Maori word that means "diver who returns with food," was first discovered in 1977, but has only recently been reconstructed by scientists in a study in the Journal of Vertebrate Paleontology.
Scientists recommend marine protected areas for Madagascar
(02/27/2012) With the government of Madagascar planning to increase marine protected areas by one million hectares, a group of researchers have laid out flexible recommendations in a new study in the open access journal PLoS ONE. The researchers employed four different analyses in order to highlight a number of different conservation options, however the different analyses pointed to the need to protect certain areas with high biodiversity, including the Barren Islands' reefs, the reefs of Juan de Nova, the Banc de Leven, and the shallow banks of the Cap Sainte Marie.
