(08/27/2014) You may have recently read the controversial story on invasive lionfish research involving Dr. Zack Jud of Florida International University and a young girl named Lauren Arrington. While the issue of attribution in scientific research is crucial to the discipline, much of the media focus so far has sidestepped the real issue: what lionfish tolerance for brackish water really means for the environment.
Of Prawns and Men on the Bali Strait
(08/22/2014) Why is shrimp so cheap? The answer: it's not. An in depth look at the shrimp farm industry in Indonesia and the true cost of this universally enjoyed delicacy. This article by Melati Kaye first appeared in the Seashore Issue of the culinary magazine Lucky Peach and was funded under Mongabay.org's Special Reporting Initiatives program.
Demand for shark fin plunging
(08/12/2014) Shark fin demand has dropped precipitously in China in just a few years, according to a new report by WildAid. Shark fin traders in Guangzhou—the current informal capital of the shark fin trade—say their sales have fallen by 82 percent in just two years, according to WildAid.
Seafood apartments and other experiments in fixing Indonesia's fisheries (Part IV)
(07/25/2014) Shrimp farms, industrial plants, and one of Indonesia's busiest thoroughfares make up Java's north coast today. It's a very different scene from the fishing villages with beachfront boat parking that stood here decades earlier. Which begs the question, where will fish live in this new 'coast without mangroves, without coral, without seagrass,' asks Alan Koropitan, a marine biologist based at Bogor Agricultural University.
Over-depleted and undermanaged: can Indonesia turn around its fisheries? (Part III)
(07/22/2014) Compared to maritime ministries worldwide, Indonesia's Ministry of Marine Affairs and Fisheries (MMAF) is a teenaged neophyte. The governing body was formed a mere 13 years ago;a staggering fact for a country made up of two-thirds water where many of the 250 million people depend on fish for both protein and income. Mongabay.org's SRI Fellow Melati Kaye reports on the state of Indonesian fisheries in the third installment of a four-part series.
Boom but mostly bust: fighting over sardines in Indonesia's Bali Strait (Part II)
(07/18/2014) Fifty-five crewmen, stripped to their briefs, sing Madurese sea shanties to synchronized gestures as they haul in giant seine nets, hand-over-hand, onto the swaying wooden deck of the M/V Sinar Indah out in the middle of the Bali Strait. This morning they had offloaded a bumper haul at their homeport of Muncar: seven tons of lemuru sardines Sardinella lemuru, the local specialty, for which dockside cannery agents offered $3,500.
Fishing for coherent regulations along Fiji's coral reefs
(07/16/2014) Will Fiji implement a much-needed update to its fisheries laws before the September election? If you want to quiet a room in Fiji or feel like a lobster in a boiling pot, bring up coastal fishing rights, and ask what's happening with the plan to update the country's fisheries laws.
A tale of two fish: cyanide fishing and foreign bosses off Sulawesi's coast (Part I)
(07/08/2014) In spring and summer, after the monsoon storms have passed, the fishing boats set out again from tiny Kodingareng Island in the Spermonde Archipelago off the coast of South Sulawesi. In the afternoon heat, Abdul Wahid joins his fellow fishermen in the narrow shade of the beachfront village houses to check out the daily fish prices.
Dying for Fiji's Sea Cucumbers
(06/23/2014) Redfish, Greenfish, Blackfish. Pinkfish, Curryfish, Lollyfish. They sound like Dr. Seuss characters and certainly look like they should be. Yet these sausage-shaped, rubbery animals stippled in fleshy bumps are not fish at all, but an invertebrate in the group that includes sea stars, sea urchins and sand dollars. Sea cucumbers, referred to as 'bêche-de-mer' or 'trepang' when sold as dried food have a high value - an individual in Fiji can fetch about $80 US.
U.S. raises $800 million for oceans, including $7 million from Leonardo DiCaprio
(06/19/2014) A U.S. State Department conference on the oceans raised an impressive $800 million for marine conservation this week. The conference was also notable for the announcement by President Obama of an intent to significantly expand the Pacific Remote Islands Marine National Monument.
Bigger than Mexico? Obama announces major expansion of Pacific protected area
(06/18/2014) President Obama announced yesterday he intends to drastically expand the Pacific Remote Islands Marine National Monument making what will likely be the largest marine protected area on the planet. While the full extent of the ocean park has yet to be determined, it could potentially protect over two million square kilometers, an area larger than Mexico.
By the bones: herring populations were superabundant before commercial fisheries
(06/09/2014) Scientists analyzed almost half a million fish bones to shed light on the population history of Pacific herring (Clupea pallasii) in the North Pacific Ocean. Their paper reveals a decline of unprecedented scale, and suggests that while the abundance of Pacific herring does fluctuate naturally, their numbers have fallen precipitously since commercial fishing started targeting the species in the 19th century.
Trawling: destructive fishing method is turning seafloors to 'deserts'
(05/28/2014) Previous research has linked trawling to significant environmental impacts, such as the harvest of large numbers of non-target species, collectively termed “bycatch,” as well as destruction of shallow seabeds. Now, a new study finds this method is also resulting in long-term, far-reaching consequences in the deeper ocean and beyond.
Former Miss South Pacific steps into new conservation role
(05/15/2014) Alisi Rabukawaqa, an articulate, vibrant, 26-year-old Fijian known in Oceania as Miss South Pacific 2011, has set her sights on a novel conservation program in Fiji. The Conservation Officer program, created in 2013, supports natural resource management within villages in Fiji and links them with the government arm overseeing the needs of indigenous Fijians. Mongabay.org Special Reporting Initiative Fellow Amy West sits down for an interview.
New Caledonia officially creates world's largest protected area (photos)
(05/02/2014) The government of New Caledonia last week officially created the world's largest protected area, establishing a multi-use zone that at 1.3 million square kilometers is three times the size of Germany, reports Conservation International (CI).
Collateral damage: new findings shed light on the full impact of commercial fishing
(04/09/2014) Aside from reducing the populations of the species sought for capture, commercial fisheries are also killing thousands of nontarget creatures such as sharks, albatross, and sea turtles, collectively referred to as “bycatch.” However, the full extent of the problem is only beginning to be grasped.
Revealed for the first time: the surprising biodiversity of algae 'reefs'
(03/28/2014) Most people are familiar with coral reefs, but very few have ever heard of their algal equivalent – rhodolith beds. Yet, these structures provide crucial habitat for many marine species. In the first study of its kind, published in mongabay.com’s Tropical Conservation Science, researchers unveil just how important these beds are for bottom-dwelling organisms, and the species that depend on them.
3 environmental reporting prize winners to explore drivers of deforestation, community forestry, and sustainable seafood in China
(03/19/2014) Mongabay.org, the non-profit arm of environmental science web site Mongabay.com, has selected winners of three environmental reporting prizes under its Special Reporting Initiatives (SRI) program. The three prizes, which were launched in January, explore the impacts of rising human consumption on forest and marine ecosystems. The winners, selected from more than 150 applicants by a panel of issue-area experts, include Robert S. Eshelman, Ruxandra Guidi and Bear Guerra, and Dominic Bracco II and Erik Vance.
Saving sharks one sandwich at a time: conservationists target 'shark bake'
(02/28/2014) Thousands of Carnival revelers in Trinidad wouldn't think of missing the chance to go to Maracas Beach, the most famous strip of sand on the small Caribbean island off the northeast coast of Venezuela. Beachgoers might not think twice about eating a favorite food called "shark bake" either – at least, until now. But this week, conservationists launched a shark-saving campaign timed to get maximum exposure out of the celebration that will bring throngs of visitors to the island.
Indonesia pledges to protect manta rays
(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.
Study: 59% of Marine Protected Areas are ineffective
(02/10/2014) Protecting large, isolated areas of no-take zones for over 10 years with strong enforcement is the key to effective Marine Protected Areas (MPAs), according to a letter published this week in Nature. However, 59% of all MPAs meet less than three of the five criteria, making them protected in name only.
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.
Scientists discover new eagle ray imperiled by Japanese pest program (photos)
(01/30/2014) Scientists have described a new species of eagle ray in the northwest Pacific Ocean, which they have named "narutobiei" (Aetobatus narutobiei) after its local name in Japan. While the new species has long been known by scientists, it was clumped together with the longheaded eagle ray (Aetobatus flagellum) for over two hundred years. Splitting the two species has large-scale conservation impacts, according to the paper describing the new species in PLOS ONE.
A series of oil spills sully Caribbean paradise, coating mangroves and wildlife (photos)
(01/29/2014) On December 17th, officials first discovered a massive oil spill in the Caribbean-island nation of Trinidad and Tobago. Since then, a series of oil spills have been discovered, coating beaches, sullying mangrove forests, and very likely decimating wildlife in Trinidad's Gulf of Paria. The oil spills have been linked to the state-owned oil company, Petrotrin, which has claimed that sabotage is behind at least two of the spills. However Trinidad and Tobago's Environmental Management Authority has recently slapped the company with a $3.1 million fine by for the damage, while some politicians have called for an independent investigation into the slew of spills.
Investigation finds Chinese factory slaughters 600 whale sharks a year
(01/29/2014) A four-year investigation by WildLifeRisk, a Hong Kong-based marine conservation group, has found that a single factory in China’s Zhejiang Province slaughters some 600 whale sharks a year to produce oil for cosmetics and health supplements.
Protected forests linked to healthy coral reefs in Fiji
(01/27/2014) Increasing forest protection in the right areas could increase benefits up to 10.4 percent to coral reef condition, according to a recent study of Fiji's forests and reefs in Marine Policy. Benefits from protected forests such as improved water quality due to decreased runoff and increased distribution of the vegetation are more closely linked to coral reef health than previously thought.
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.
Photos: Japanese fishermen slaughter 41 dolphins, capture 52 in 'The Cove'
(01/21/2014) The annual dolphin hunt in Taiji, Japan ended on Monday with dozens being slaughtered for meat and captured for sale to amusement parks, reports Sea Shepherd, an ocean activist group that campaigns against the practice and just released photos documenting the weekend's harvest.
Two journalists awarded prizes for reporting on fisheries in the Pacific
(01/20/2014) Mongabay.org - a non-profit dedicated to raising awareness of social and environmental issues relating to tropical forests and other ecosystems - has announced the winners of two environmental reporting prizes under its Special Reporting Initiative (SRI) program. The prizes sought proposals to investigate questions around marine fisheries management in the Pacific.
Environmental groups: top secret Pacific trade agreement to sacrifice wildlife, environment
(01/16/2014) Environmental groups have blasted draft text of the Trans-Pacific Partnership (TPP) released yesterday by WikiLeaks as potentially devastating to the environment and wildlife. The massive 12-nation free trade agreement has been negotiated in secret now for almost four years, and the information release by WikiLeaks shows that key environmental safeguards in the agreement are being stripped away, including a ban on shark finning and illegal logging, as well as legally-enforced pollution regulations.
Japanese whale hunt stopped, for now
(01/06/2014) Anti-whaling group Sea Shepherd said its fleet of ships has successfully disrupted the annual Japanese whale hunt in the waters off Antarctica.
China bans shark fin, bird's nest soup from state banquets
(12/10/2013) China has banned shark fin and bird's nest soup from being served at official state banquets, reports Chinese state media.
Google Earth reveals fish catch is 6 times greater than thought in Persian Gulf
(11/27/2013) Google Earth has once again been used by researchers for scientific discovery.
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.
Nearly half a million seabirds die in gillnets every year, but solutions exist
(11/18/2013) A recent study from the Biological Conservation journal brings shocking news: every year across the globe, an estimated 400,000 seabirds are killed by gillnets. Gillnets, a common term for any net used to entangle and catch fish, are used all over the world, and at any depth. These nets, whether used in subsistence or commercial fishing, trap anything that swims through them. When unintended marine wildlife, or "bycatch," is caught in these nets, the results can be significant.
Longline fisheries in Costa Rica hook tens of thousands of sea turtles every year
(11/14/2013) Hundreds of kilometers of commercial fishing lines slither along coastal waters in Costa Rica, hooking thousands of mahi-mahi and many other marketable fish. But when scientists scrutinized fishermen’s catch, they were shocked by the staggering number of sea turtles accidentally snagged on the lines.
Ultraviolet nets significantly reduce sea turtle bycatch
(11/11/2013) Bycatch, a side-effect of commercial fishing in which non-target species are accidentally caught, is linked to severe population declines in several species. Sea turtles are particularly impacted by small-scale coastal gillnetting practices, in which large nets are deployed and indiscriminately snag anything of a certain size that attempts to swim through them. However, that may soon change.
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.
DNA tests reveal new dolphin species (photos)
(10/30/2013) With the help of DNA tests, scientists have declared a new dolphin species that dwells off the coast of northern Australia. The discovery was made after a team of researchers looked at the world's humpback dolphins (in the genus Sousa), which sport telltale humps just behind their dorsal fins. While long-known to science, the new, as-yet-unnamed species was previously lumped with other humpback dolphins in the Indo-Pacific region.
Fishermen illegally killing dolphins for shark-bait in Peru (video)
(10/23/2013) Peruvian fishermen slaughtered dolphins to use as bait for shark fishing, an undercover investigation has revealed. Footage showed infant and adult dolphins being harpooned then stabbed and clubbed before, in some cases, being cut open and butchered while still alive. The slaughtered dolphins were cut up and used as bait. Dolphins are also killed for human consumption in Peru even though it is illegal.
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.
President's pledge to ban commercial fishing around Pacific island nation slow to materialize
(09/23/2013) In 2010 President Anote Tong of Kiribati made a historic pledge, committing to protect the waters around his island nation in a massive marine protected area. He said the gesture represented Kiribati’s contribution to protecting the environment and he urged industrial countries to do the same by cutting their greenhouse gas emissions, which threaten low-lying islands with rising sea levels. The commitment raised Tong’s profile, winning him international accolades, and boosted the tiny country’s standing in the fight against climate change. But since 2010 questions have begun to emerge about the extent of Tong’s commitment.
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.
Are sea turtles responsible for lower fish catches in India?
(08/29/2013) Fishing communities on Agatti Island in Lakshwadeep, India, blame their reduced fish catch on green turtles; according to them, green turtles chomp their way through the seagrass beds lining the shallow reef waters that are essential for fish to breed. This leads some in the community to clandestinely kill sea turtles and destroy their nests.
Eighty sea turtles wash up dead on the coast of Guatemala
(08/27/2013) An assortment of marine animals and birds reside along the black volcanic sand beaches of Guatemala’s Pacific coast, but lately both residents and visitors on the southeast beaches of the country have observed a tragic event – the stranding of dead sea turtles. Eighty dead sea turtles have been recorded since the first week of July.
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?
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.
Local economy ruined by pesticide pollution in the Caribbean
(05/29/2013) On 15 April more than 100 fishermen demonstrated in the streets of Fort de France, the main town on Martinique, in the French West Indies. In January they barricaded the port until the government in Paris allocated €2m ($2.6m) in aid, which they are still waiting for. The contamination caused by chlordecone, a persistent organochlorine pesticide, means their spiny lobsters are no longer fit for human consumption. The people of neighboring Guadeloupe are increasingly angry for the same reason. After polluting the soil, the chemical is wreaking havoc out at sea, an environmental disaster that now threatens the whole economy.
Scientists discover high mercury levels in Amazon residents, gold-mining to blame
(05/28/2013) The Madre de Dios region in Peru is recognized for its lush Amazon rainforests, meandering rivers and rich wildlife. But the region is also known for its artisanal gold mining, which employs the use of a harmful neurotoxin. Mercury is burned to extract the pure gold from metal and ore producing dangerous air-borne vapors that ultimately settle in nearby rivers. 'Mercury in all forms is a potent neurotoxin affecting the brain, central nervous system and major organs,'Luis Fernandez, an ecologist and research associate at the Carnegie Institution's Department of Global Ecology, told mongabay.com. 'At extremely high exposure levels, mercury has been documented to cause paralysis, insanity, coma and death.'
Indonesia's largest coal plant will be built despite protests, minister says
(05/26/2013) Indonesia will go ahead with construction of what is set to be its largest coal-fired power plant in Batang, Central Java next year, a senior government official has said, downplaying opposition from environmental groups and the local community. Developers have struggled to acquire the approximately 200 hectares of land needed for the planned PLTU Batang plant, which would have a 2000 megawatt (MW) capacity. Residents of five villages have protested the project, with some refusing to release their land on fears of potential environmental damage to the area. Environmental groups also oppose the plant, saying it overlaps with a marine protected area and runs counter to President Susilo Bambang Yudhoyono’s commitment to reduce carbon emissions.
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.
Pacific islanders are the 'victims of industrial countries unable to control their carbon dioxide emissions'
(05/15/2013) With islands and atolls scattered across the ocean, the small Pacific island states are among those most exposed to the effects of global warming: increasing acidity and rising sea level, more frequent natural disasters and damage to coral reefs. These micro-states, home to about 10 million people, are already paying for the environmental irresponsibility of the great powers.
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.
Featured video: saving sea turtles in Mexico's Magdalena Bay
(05/09/2013) A new short film, Viva la tortuga documents the struggle to save loggerhead and green sea turtles in Magdalena Bay, Mexico. Once a region for a massive sea turtle meat market, the turtles now face a new threat: bycatch. Loggerhead sea turtles are drowning in bottom-set gillnets, unable to escape from the nets once entangled. The issue has even raises threats of trade embargoes from the U.S.
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.
Heavy metal shark meat: dangerous lead levels found in sharks used as fish food
(03/18/2013) A recent study published in mongabay.com’s open access journal Tropical Conservation Science raises concerns about levels of heavy metals, particularly lead (Pb), present in shark meat, as well as the decline of shark abundance due to global fishing pressures. Sharks are primarily caught as by-catch for other fishing industries. By one account, 70% of the total catch in swordfish long-line fisheries was sharks. Due to consumer demand, this by-catch is sold to Asian fish markets as fin and trunk meat. Much of the trunk and organ meat is used to make fish-meal, which is then fed to farmed fish.
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.
Fish unable to pass through dams in U.S. presents 'cautionary tale' for developing world
(01/17/2013) Dams create a largely impenetrable barrier for fish even when the dams were installed with specially-built passages, according to a new study in Conservation Letters. The scientists found that migrating fish largely failed to use the passages in the U.S., resulting in far fewer moving through the state-of-the-art hydroelectric dams than had been promised. The researchers say that their findings are a "cautionary tale" for developing nations.
Gold mine approved in French Guiana's only national park
(01/15/2013) Tensions have risen in the small Amazonian community of Saül in French Guiana after locals discovered that the French government approved a large-scale gold mining operation near their town—and inside French Guiana's only national park—against their wishes. Run by mining company, Rexma, locals and scientists both fear that the mine would lead to deforestation, water pollution, and a loss in biodiversity for a community dependent on the forest and ecotourism.
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.
The genetically modified 'Frankenfish' salmon soon in a plate near you
(01/10/2013) The U.S. Food and Drug Administration (FDA) has partially approved the AquAdvantage Salmon, a genetically engineered salmon that grows twice as fast as normal. The FDA states that the GM salmon is “safe and unlikely to harm the health of the consumers or the environment”.

Obama triples area of protected California coastline
(12/20/2012) Today President Obama announced the government would add almost 3,000 square miles of California coastline to the National Marine Sanctuary system, roughly tripling its size, reports the Sierra Club.
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.
World has lost half its wetlands
(11/29/2012) Half of the worlds wetlands have been destroyed in just the last 100 years, says a new report. Published by the Economics of Ecosystems and Biodiversity (TEEB), the report found that of the 25 million square kilometers of wetlands that existed in 1900 just 12.8 million square kilometers now remain. The rate of destruction varies geographically with notable loses in East Asia running at 1.6 per cent per year. In places where aquaculture, over-exploitation (e.g. unsustainable harvesting of fish) and storm damage have been severe, the rate of destruction can be as high as 80 percent.
Investors shouldn't ignore financial risk of environmental damage
(11/29/2012) Environmental damage poses a long-ignored risk to sovereign bonds, according to a new report by the UNEP FI (The United Nations Environment Programme Finance Initiative) and the Global Footprint Network. The report, E-RISC Report, A New Angle on Sovereign Credit Risk, finds that the overuse of natural resources and their degradation has put considerable, and largely unrecognized, risk against national economies.
Legislation leaves future of world's largest temperate rainforest up in the air
(11/27/2012) Although unlikely to pass anytime in the near term, recurring legislation that would hand over 80,000 acres of the Tongass Rainforest to a Native-owned logging corporation has put local communities on guard in Southeast Alaska. "The legislation privatizes a public resource. It takes land that belongs to all of us, and that all of us have a say in the use and management of, and it gives that land to a private for-profit corporation," Andrew Thoms, Executive Director of the Sitka Conservation Society, told mongabay.com in a recent interview.
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.
Photos: Mozambique creates Africa's biggest marine protected area
(11/13/2012) Last week, the East African nation of Mozambique announced it was protecting 10,411 square kilometers (4,020 square miles) of coastal marine waters, making the new Marine Protected Area (MPA) the biggest on the continent. The protected area, dubbed the Primeiras and Segundas Archipelago ("First" and "Second" islands), includes ten islands as well as mangrove forests, rich coral reefs, and seagrass ecosystems.
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.
Future of the Tongass forest lies in salmon, not clear-cut logging
(10/25/2012) The Parnell administration's Timber Task Force recently unveiled a proposal to carve out two million acres of the Tongass National Forest for clear-cut logging under a state-managed "logging trust." The stated goal is to revive Southeast Alaska’s timber industry that collapsed two decades ago amid changing market conditions, logging cutbacks and evolving public opinion about timber harvesting on national forests.
A new way to measure the ocean's health
(10/23/2012) A diverse array of institutions have come together to release a new, revolutionary ocean health assessment called the "Ocean Health Index." Researchers formed the index in order to gauge the health of the world’s oceans. The index is the result of a huge collaborative effort, including top researchers crossing a diverse range of disciplines such as the National Center for Ecological Analysis and Synthesis (NCEAS) and Conservation International.
Indigenous groups re-occupy Belo Monte dam in the Amazon
(10/09/2012) Construction on Brazil's megadam, Belo Monte, has been halted again as around 150 demonstrators, most of them from nearby indigenous tribes, have occupied the main construction site at Pimental. Over a hundred indigenous people joined local fishermen who had been protesting the dam for 24 days straight. Indigenous people and local fishermen say the dam will devastate the Xingu River, upending their way of life.
Livelihoods depend on the environment in the Western Ghats
(09/27/2012) In the Uttar Kannada district of the Western Ghats, the livelihood of the average individual depends largely on the well being of the environment. Six months ago, before large-scale mangrove planting of the area, if someone were to walk through the banks of the mangroves in the Western Ghats he would see many fishermen casting their long nets and wires, time and time again noticing pieces of trash such as plastic grocery bags tangled in the nets.
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.
Mekong dam spree could create regional food crisis
(08/27/2012) Fish are a hugely important protein source for many people around the world. This is no more evident than along the lower Mekong River delta where an estimated 48 million people depend directly on the river for food and livelihoods. But now a new study in Global Environmental Change cautions that 11 planned hydroelectric dams in the region could cut vital fish populations by 16 percent while putting more strain on water and land resources.
Chinook salmon return to Olympic National Park after dam demolished
(08/21/2012) In March of this year the Elwha Dam, which had stood for 99 years, was demolished in the U.S. state of Washington. Five months later, Chinook salmon (Oncorhynchus tshawytscha) made their way down 70 miles of long-blocked off habitat and entered Olympic National Park.
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.
Featured video: restoring rivers in the Tongass Rainforest
(08/08/2012) A new video highlights recent efforts to restore rivers in the Tongass Forest, the world's largest intact temperate rainforest. Industrial logging in vital watersheds have hurt salmon populations and other wildlife in the region, an issue the government, along with several partners, are now trying to rectify.
Maui's dolphins still in danger of extinction despite New Zealand's protective measures
(08/07/2012) The New Zealand government's recent efforts to protect the world’s smallest dolphin have come under scrutiny from various conservation organizations at the 64th meeting of the International Whaling Commission (IWC). There are only 55 Maui dolphins (Cephalorhynchus hectori maui) now found on the west coast of New Zealand’s North Island, less than half the 2005 population with numbers continuing to decline. Less than 20 of the remaining Maui’s are breeding females and their slow reproductive rates make it difficult to increase their numbers when faced with an even bigger danger: fishing nets.
'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.
The vanishing Niger River imperils tourism and livelihoods in the desert
(06/04/2012) Severely affected by recent turmoil across its northern frontiers, Nigerien tourism pins hope on river valley attractions to play a major role in rebuilding its tourism industry in the upcoming years. Even though the river itself is threatened. Located in the heart of the Sahel Region, the vast desert lands of Niger have captivated European tourists seeking a taste of its immensely varied natural landscapes.
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.
Nearly 2,000 fish species traded in U.S. tropical aquarium market
(05/24/2012) The U.S. tropical aquarium market poses problems and opportunities for conservation, according to a landmark study published in the open-access journal PLoS ONE. The study reviewed import records in the U.S. for one year (2004-2005) and found that over 11 million wild tropical fish from 1,802 species were imported from 40 different countries. While the number of fish species targeted surprised researchers, the total amount of fish imported was actually less than expected.
Charting a new environmental course in China
(05/21/2012) Founded in 1951, The Nature Conservancy (TNC) works in more than 30 countries and has projects in all 50 of the United States. The Conservancy has over one million members, and has protected more than 119 million acres of wild-lands and 5,000 miles of rivers worldwide. TNC has taken an active interest in China, the world's most populated nation, and in many important ways, a critical center of global development. The following is an interview with multiple directors of The Nature Conservancy's China Program.
