Ocean contributes $2.5 trillion to economy annually
(04/24/2015) A new study attempts to place a value of goods and services afforded by the ocean, estimating that if the planet's seas were classified as a country, it would rank as the world's seventh largest economy.
Indonesian ombudsman asks minister to offer fishermen ‘exit strategy' from seining
(04/22/2015) On Sunday, the Indonesian ombudsman asked the maritime affairs minister to help fishermen adapt to the government's new ban on seine and trawl fishing, a response to locals' complaints that they had already made big investments in procuring and installing the now-prohibited gear.
Overfishing leads to crashes in sardines and other forage fish
(04/07/2015) Some of the smallest fish in the sea play an outsize role in marine ecosystems. Populations of sardines, anchovies, and other so-called "forage fish" have undergone stupendous crashes whose effects ripple outward across the food web. New research shows that overfishing has caused or worsened these crashes and suggests some simple tweaks to fisheries management that could help fishermen and fish alike.
Minister explains sustainability claims behind Indonesia’s boat bombing
(03/17/2015) Boat bombing has been one of the most visible (and internationally controversial) elements of the new Indonesian fishery minister’s policies. But recently, Fishery Minister Susi Pudjiastuti explained that the bombings were really based on the concept of sustainability.
Human impacts are 'decoupling' coral reef ecosystems
(03/09/2015) There is a growing consensus among scientists that we have entered the age of the Anthropocene, or the epoch of humans. In other words, at some point between the 12,000 years separating the beginning of agriculture and the Industrial Revolution, humans became the dominant source of change on the planet, shaping everything from the land to the atmosphere to even the geologic record where we etch our reign.
Indonesian fisheries ministry imposes new limits on gear and fish harvests
(03/04/2015) The Indonesian fisheries ministry has introduced two divisive pieces of legislation aimed at increasing the sustainability of Indonesia’s depleted ocean fisheries. Permen KP 1/2015 imposes size limits on wild-caught lobsters and crab, and forbids catching egg-bearing crustaceans. Permen KP 2/2015 bans trawl and seine fisheries. Fishermen last Thursday demonstrated outside the Ministry to protest the damage this will cause to their livelihoods.
Last ditch: Mexico finally gets serious about saving the vaquita
(03/04/2015) There are likely less than 100 vaquita on the planet. Found only in the northern pocket of the Sea of Cortez in Mexico, the vaquita is a tiny, shy porpoise that has been brought to the very edge of extinction due to drowning in gillnets used for shrimping. But after years of stalling, Mexico now appears to be making a final effort to save the world's most endangered cetacean.
Employing shame for environmental change
(03/03/2015) Anyone who has ever felt the sting of shame, knows its power. Shame has long been used by societal institutions—families, communities, governments, religions—for making individuals tow the line of the majority. But a new book explores another—arguably more positive—side of shame: its potential to challenge rule-breaking and ethically-defunct corporations.
Ocean's 15: meet the species that have vanished forever from our seas
(01/15/2015) In the last 500 years, the oceans have suffered far fewer extinctions than on land—at least that we know of. According to a recent study in Science, 15 animals are known to have vanished forever from the oceans while terrestrial ecosystems have seen 514 extinctions. The researchers, however, warn that the number of marine extinctions could rise rapidly as the oceans are industrialized.
Empty seas? Scientists warn of an industrialized ocean
(01/15/2015) This is obvious, but still important: humans are not a marine species. Even as we have colonized most of our planet's terrestrial landscapes, we have not yet colonized the oceans. And for most of our history, we have impacted them only on the periphery. A new review in Science finds that this has saved marine species and ecosystems from large-scale damage—that is, until the last couple centuries.
Casting for another job: will fishers take up a new livelihood?
(01/12/2015) Can alternative income programs save Fiji's reef fish? Many implicate the failure of Fiji's government to prioritize sustainable management over fisheries development projects, or suggest that Fijians' mindsets must dramatically shift first.
For the first time, Sea Shepherd targets Antarctic toothfish poachers
(12/09/2014) For the first time, marine conservation group, Sea Shepherd, is employing their controversial methods to protect Antarctic and Patagonian toothfish. Dubbed 'Operation Icefish,' Sea Shepherd Australia is sending two ships into Antarctic waters to disrupt illegal vessels targeting the little-known species that are often sold in luxury markets as Chilean seabass.
New marine protected areas key to fighting illegal fishing
(11/24/2014) Do you know how that tuna sashimi got to your dinner plate? Probably not—and chances are, the restaurant that served it to you doesn’t know, either. A new policy paper argues that illicit fishing practices are flying under the radar all around the world, and global society must combat them in order to keep seafood on the menu.
Of bluefin and pufferfish: 310 species added to IUCN Red List
(11/17/2014) Today, 22,413 species are threatened with extinction, according to the most recent update of the IUCN Red List. This is a rise of 310 species from the last update in the summer. The update includes the Pacific bluefin tuna, the Chinese pufferfish, and Chapman's pygmy chameleon, among others.
Russia and China blamed for blocking Antarctic marine reserve
(11/03/2014) Another year, another failed attempt to protect a significant chunk of the Ross Sea, which sits off the coast of Antarctica. According to observers, efforts to create the world's biggest marine protected area to date were shot down by Russia and China during a meeting in Hobart, Tasmania of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).
By killing off older fish, overfishing may lead to lost migratory patterns
(10/29/2014) Catching older fish may impact a school's ability to migrate from spawning grounds to feeding areas, according to a recent study published in the Journal of the Royal Society Interface. The study’s scientists believe that fish schools may retain a collective memory, a communal mind map of sorts, which help these groups reach their destinations, some of which are thousands of miles away.
Saving the survivor: China scrambles to keep the finless porpoise from extinction
(10/22/2014) On the morning of July 14, 2002 Qi Qi ate breakfast as he always did. As the world’s only captive baiji – or Yangtze river dolphin – Qi Qi was something of a celebrity in China and his caretakers kept a close eye on his health. That care may explain why, after being injured by fishermen, he lived an impressive 22 years in the Freshwater Dolphin Research Center in Wuhan, China.
Blue-footed boobies on the decline, plummeting sardine stocks may be to blame
(08/06/2014) The iconic blue-footed booby of the Galapagos Islands has suffered a population decline of 50 percent in less than 20 years, according to research conducted by biologists from Wake Forest University.
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.
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.
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.
Photo: Bluefin tuna sells for record $1.76 million in Japan
(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.
New sanctuaries declared for Asia's freshwater dolphins
(02/15/2012) Bangladesh has declared three new sanctuaries to help protect the south Asian river dolphin (Platanista gangetica) in the Sundarbans, the world's largest mangrove forest. Split into two subspecies, the Ganges River dolphin (Platanista gangetica gangetica) and the Irrawaddy River dolphin (Platanista gangetica minor), the new sanctuaries will benefit both. Listed as Endangered by the IUCN Red List, the south Asian freshwater dolphin has disappeared from much of its habitat. Already Asia has its other freshwater dolphin species: the baiji (Lipotes vexillifer) was declared functionally extinct into 2006 after a survey of the Yangtze River failed to find a single individual.
Jellyfish explosion may be natural cycle
(02/06/2012) Evidence that jellyfish are taking over the oceans is currently lacking, according to a new study published in Bioscience. Complied by a number of marine experts, the study found that while jellyfish have been on the rise in some regions it is likely due to a natural cycle of jellyfish populations and not a global boom. Researchers, including a number of marine biologists, have warned for years that jellyfish numbers may be exploding due to human activities, such as overfishing, warmer oceans due to global climate change, and the rise of oxygen-depleted, so-called "dead zones."
Atlantic sturgeon gains protection under the Endangered Species Act
(02/01/2012) The U.S. federal government has listed the massive and bizarre Atlantic sturgeon (Acipenser oxyrinchus) under the protection of the Endangered Species Act (ESA). Historically overfishing decimated the Atlantic sturgeon, while on-going threats include pollution and infrastructure, like dams and bridges that destroy habitat. Fishing for the Atlantic sturgeon has been banned since 1998, they are still caught as bycatch.
Cute animal picture of the day: pygmy killer whale saved after stranding
(01/12/2012) On Tuesday a female pygmy killer whale (Feresa attenuata) was found stranded on Tanjung Aru beach, in the Malaysian state of Sabah on the island of Borneo. After being moved to a swimming enclosure at a local resort for recuperation, the whale was released back into the wild with aid from the Sabah Wildlife Department, marine biologist Lindsay Porter, the local NGO LEAP, and WWF Malaysia.
Bycatch-reducing fish trap wins $20,000
(01/11/2012) An innovative fish trap that allows small non-target fish to escape won a new content by RARE Conservation and National Geographic to fund solutions to overfishing. Developed through studies in Curaçao and Kenya with the Wildlife Conservation Society, the trap has gaps for juvenile fish to swim out of reportedly reducing bycatch by 80 percent. The entry won a $20,000 grant.
World's most expensive tuna
(01/05/2012) A 593 pound Pacific bluefin tuna sold for $735,000 (56.49 million yen) in Tokyo's Tsukiji market today. This beats the previous record price hit last year by over $260,000. Why so expensive? Bluefin tuna, considered the best sashimi and sushi in the world, have been fished to near extinction with the population of the Pacific bluefin the most stable to date.
Seahorses under stress
(11/21/2011) With about 25 million seahorses sold each year, global consumption of seahorses is massive. They’re used in traditional Asian medicine and also sold as curios and aquarium pets. Over the last decade, overexploitation and habitat degradation have prompted declines of between 15 to 70 percent in many seahorse populations. Marine biologist and author Helen Scales notes there is much still unknown about seahorses.
PHOTO: Adorable penguin chicks score their own blog
(11/15/2011) A new blog, dubbed the Real Chicks of Central Park, is allowing visitors an intimate look at eight impossibly-cute penguin chicks. Including video, photos, and interviews the blog is an attempt to raise awareness about penguins. The highlighted chicks include four gentoo penguins (Pygoscelis papua) and four chinstrap penguins (Pygoscelis antarcticus).
US reduces catch limit of 'most important fish in the sea'
(11/15/2011) The Atlantic State Marine Fisheries Commission (ASMFC) has slashed the allowable catch of a tiny fish named menhaden by 37 percent by 2013. Dubbed the 'most important fish in the sea' by author H. Bruce Franklin, the menhaden plays a critical role in marine ecosystems as a food source for larger fish, seabirds, and marine mammals, as well as helping to regulate the marine environment. However, due to overfishing the menhaden fish has dropped 92 percent from its historical population.
Covert Creatures: The Clandestine Lives of Seahorses
(11/15/2011) Seahorses are strange looking creatures, with a horse's head on top of a kangaroo’s pouched belly, bulging, swiveling chameleon eyes, a prehensile monkey tail, color-changing armor and a royal crown, all shrunk down to the size of a chess piece. To marine biologist Helen Scales, these elusive creatures are a perfect symbol of the ocean's biodiversity.
First global assessment finds highest-grossing tunas and billfishes most vulnerable to extinction
(11/09/2011) Sleek, powerful tunas and billfishes that ply the open ocean garner some of the highest prices of any fish. In January, a single bluefin tuna fetched a record $396,000 at a Tokyo auction. Yet wild fish populations pay a still higher price for such exorbitant demand: the threat of extinction. The first assessment of an entire group of commercially valuable marine species found that the most threatened fish are generally the ones reeling in the most money, including bluefin tuna and bigeye tuna.
11 challenges facing 7 billion super-consumers
(10/31/2011) Perhaps the most disconcerting thing about Halloween this year is not the ghouls and goblins taking to the streets, but a baby born somewhere in the world. It's not the baby's or the parent's fault, of course, but this child will become a part of an artificial, but still important, milestone: according to the UN, the Earth's seventh billionth person will be born today. That's seven billion people who require, in the very least, freshwater, food, shelter, medicine, and education. In some parts of the world, they will also have a car, an iPod, a suburban house and yard, pets, computers, a lawn-mower, a microwave, and perhaps a swimming pool. Though rarely addressed directly in policy (and more often than not avoided in polite conversations), the issue of overpopulation is central to environmentally sustainability and human welfare.
Small marine fish need protection too
(10/25/2011) It has long been known that overfishing has decimated some populations of tuna, shark, cod, as well as other big predatory fish; however two recent studies have pointed out that overfishing is also threatening small fish such as anchovies, sardines, mackerel, herring, menhaden, and krill. Although tiny, these species are vital to marine ecosystems since many species higher up on the food chain—from seabirds to marine mammals to big fish—wholly depend on them for survival.
Fishing industry exceeds Atlantic bluefin quota by 141 percent
(10/18/2011) In 2010 the fishing industry exceeded its quota of eastern Atlantic bluefin tuna (Thunnus thynnus) by 141 percent, according to a new analysis by Pew Environment Group. The analysis depends on official data, thereby leaving out the massive black market on Atlantic bluefin tuna.
Poor in Madagascar see fish plundered for foreign consumption
(10/11/2011) A new study warns that overfishing could exacerbate poverty and political stability in one of the world's poorest nations: Madagascar. According to the recent study by the University of British Columbia's Sea Around Us Project and Malagasy NGO Blue Ventures, fish catches in the African island-nation from 1950 to 2008 are actually double the official numbers, with foreign wealthy nations currently taking half the haul.
Marshall Islands creates world's biggest shark park
(10/03/2011) The Republic of the Marshall Islands has created the world's biggest shark reserve: so large that all of Mexico could fit comfortably inside. With new legislation, commercial shark fishing is now completely banned in Marshall Islands' 768,547 square miles (1,990,530 square kilometers) of ocean.
Sowing the seeds to save the Patagonian Sea
(09/07/2011) With wild waters and shores, the Patagonia Sea is home to a great menagerie of marine animals: from penguins to elephants seals, albatrosses to squid, and sea lions to southern right whales. The sea lies at crossroads between more northern latitudes and the cold bitter water of the Southern Ocean, which surround Antarctica. However the region is also a heavy fishing ground, putting pressure on a number of species and imperiling the very ecosystem that supplies the industry. Conservation efforts, spearheaded by marine conservationist Claudio Campagna and colleagues with the Wildlife Conservation Society (WCS), are in the early stages. Campagna, who often writes about the importance of language in the fight for preservation, has pushed to rename the area to focus on its stunning wildlife.
California moves closer to banning shark fin trade
(09/07/2011) California moved a step closer to banning the sale and trade of shark fin with the passage Tuesday of Senate Bill 376. The bill, which passed 25-9, now goes the governor, whose approval would make the ban law. The bill was introduced to the California State Assembly February this year by Paul Fong (D-Cupertino) and Jared Huffman (D-San Rafael).
Honduras protects sharks in all its waters
(06/26/2011) Endangered sharks are finding more sanctuaries. Honduras has announced that commercial shark fishing will be banned from its 92,665 square miles (240,000 square kilometers) of national waters. Honduras says the ban, which follows a moratorium on shark fishing, will bring in tourism revenue and preserve the marine environment.
Ocean prognosis: mass extinction
(06/20/2011) Multiple and converging human impacts on the world's oceans are putting marine species at risk of a mass extinction not seen for millions of years, according to a panel of oceanic experts. The bleak assessment finds that the world's oceans are in a significantly worse state than has been widely recognized, although past reports of this nature have hardly been uplifting. The panel, organized by the International Program on the State of the Ocean (IPSO), found that overfishing, pollution, and climate change are synergistically pummeling oceanic ecosystems in ways not seen during human history. Still, the scientists believe that there is time to turn things around if society recognizes the need to change.
What does Nature give us? A special Earth Day article
(04/22/2011) There is no question that Earth has been a giving planet. Everything humans have needed to survive, and thrive, was provided by the natural world around us: food, water, medicine, materials for shelter, and even natural cycles such as climate and nutrients. Scientists have come to term such gifts 'ecosystem services', however the recognition of such services goes back thousands of years, and perhaps even farther if one accepts the caves paintings at Lascaux as evidence. Yet we have so disconnected ourselves from the natural world that it is easy—and often convenient—to forget that nature remains as giving as ever, even as it vanishes bit-by-bit. The rise of technology and industry may have distanced us superficially from nature, but it has not changed our reliance on the natural world: most of what we use and consume on a daily basis remains the product of multitudes of interactions within nature, and many of those interactions are imperiled. Beyond such physical goods, the natural world provides less tangible, but just as important, gifts in terms of beauty, art, and spirituality.
Giant fish help grow the Amazon rainforest
(04/12/2011) A fruit in the flooded Amazon falls from a tree and plops in the water. Before it can even sink to the floor, a 60-pound monster fish with a voracious appetite gobbles it. Nearly a week later—and miles away—the fish expels its waste, including seeds from the fruit eaten long ago and far away. One fortunate seed floats to a particularly suitable spot and germinates. Many years later the new fruit tree is thriving, while the same monster-fish returns from time-to-time, waiting for another meal to drop from the sky. This process is known as seed-dispersal, and while researchers have studied the seed-dispersal capacity of such species as birds, bats, monkeys, and rodents, one type of animal is often overlooked: fish.
15 conservation issues to watch
(03/14/2011) Deforestation, oil spills, coral acidification: these are just a few examples of ongoing, and well-researched, environmental changes that are imperiling the world's biodiversity. But what issues are on the horizon? At the end of 2010, experts outlined in Trends in Ecology & Evolution 15 issues that may impact conservation efforts this year and beyond, but are not yet widely known. These are issues you may never hear about it again or could dominate tomorrow's environmental headlines. "Our aim was to identify technological advances, environmental changes, novel ecological interactions and changes in society that could have substantial impacts on the conservation of biological diversity […] whether beneficial or detrimental," the authors write in the paper. Experts originally came up with 71 possible issues and then whittled it down to the 15 most important—and least known.
Mitsubishi and Walmart agree to clean up fish sourcing practices
(03/09/2011) Two big players in seafood today announced that they are changing the way their fish are caught. Mitsubishi, which owns the UK's most popular brand for tuna in a tin, Princes, and Walmart, which owns Asda, have agreed to stop buying from fishermen who use purse seines fishing in conjunction with fish aggregating devices (FADs) by 2014. These methods have been blamed in part for the vast overfishing of the world's tuna and helping to decimate other species, such as sharks and rays, as bycatch.
Coral crisis: 75% of the world's coral reefs in danger
(02/23/2011) Marine scientists have been warning for years that coral reefs, the most biodiverse ecosystems in the ocean, are facing grave peril. But a new comprehensive analysis by the World Resources Institute (WRI) along with twenty-five partners ups the ante, finding that 75% of the world's coral reefs are threatened by local and global impacts, including climate change. An updating of a 1996 report, the new analysis found that threats had increased on 30% of the world's reefs. Clearly conservation efforts during the past decade have failed to save reefs on a large-scale.
Arctic fish catch vastly underreported (by hundreds of thousands of metric tons) for 5 decades
(02/07/2011) From 1950 to 2006 the United Nation Food and Agriculture Agency (FAO) estimated that 12,700 metric tons of fish were caught in the Arctic, giving the impression that the Arctic was a still-pristine ecosystem, remaining underexploited by the world's fisheries. However, a recent study by the University of British Colombia Fisheries Center and Department of Earth and Ocean Sciences throws cold water on this widespread belief. According to the study, published in Polar Biology, the total Arctic catch from 1950 to 2006 is likely to have been nearly a million metric tons, almost 75 times the FAO's official record.
The ocean crisis: hope in troubled waters, an interview with Carl Safina
(02/07/2011) Being compared—by more than one reviewer—to Henry Thoreau and Rachel Carson would make any nature writer's day. But add in effusive reviews that compare one to a jazz musician, Ernest Hemingway, and Charles Darwin, and you have a sense of the praise heaped on Carl Safina for his newest work, The View from Lazy Point: A Natural Year in an Unnatural World. Like Safina's other books, The View from Lazy Point focuses on the beauty, poetry, and crisis of the world's oceans and its hundreds-of-thousands of unique inhabitants. Taking the reader on a journey around the world—the Arctic, Antarctic, and the tropics—Safina always returns home to take in the view, and write about the wildlife of his home, i.e. Lazy Point, on Long Island. While Safina's newest book addresses the many ways in which the ocean is being degraded, depleted, and ultimately imperiled as a living ecosystem (such as overfishing and climate change) it also tweezes out stories of hope by focusing on how single animals survive, and in turn how nature survives in an increasingly human world. However, what makes Safina's work different than most nature writing is his ability to move seamlessly from contemporary practical problems to the age-old philosophical underpinnings that got us here. By doing so, he points a way forward.
Record high fish consumption keeps populations imperiled
(02/01/2011) More people than ever are eating more fish than ever, according to a new report by the United Nations covering the year 2008. At the same time, fish populations in the world's oceans continue to decline threatening marine ecosystems, food security, and the fishing industry itself.
Italy and Panama continue illegal fishing, says new report
(01/15/2011) On Wednesday, the National Oceanic and Atmospheric Administration (NOAA) issued its biennial report identifying six countries whose fisheries have been engaged in illegal, unreported, or unregulated (IUU) fishing during the past two years. The report comes at a time when one-fifth of reported fish catches worldwide are caught illegally and commercial fishing has led to a global fish stock overexploitation of an estimated 80 percent.
Japanese firm is deadliest for marine life, says Greenpeace
(01/10/2011) Greenpeace has ranked the canned tuna corporation Princes as the most environmentally damaging tuna brand in the U.K., citing that the Japanese company uses destructive fishing methods and that its claims of sustainability are blatantly untrue.
Bluefin tuna gets record price ($396,000) at Japanese auction
(01/06/2011) On Tuesday, a 752-pound Pacific bluefin tuna was sold at Japanese auction for the highest price ever received for raw seafood - $396,000. The price tops the previous record by more than $100,000 and comes at a time when tuna populations around the world are experiencing precipitous declines.
