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.
Coelacanths might be monogamous, to the surprise of researchers
(11/14/2013) They evaded humans for millions of years and live very private lives. The hulking, fleshy-finned fish known as the coelacanth has beguiled scientists for generations. But the coelacanth mystique that enchants researchers also makes it difficult to study. Researchers recently revealed in Nature Communications one startling aspect of the coelacanth lifestyle: they might be monogamous.
Scientist splits Amazonian giants into separate species
(10/23/2013) It's hard to mistake an arapaima for anything else: these massive, heavily-armored, air-breathing fish (they have to surface every few minutes) are the megafauna of the Amazon's rivers. But despite their unmistakability, and the fact that they have been hunted by indigenous people for millennia, scientists still know relatively little about arapaima, including just how many species there are. Since the mid-Nineteenth Century, scientists have lumped all arapaima into one species: Arapaima gigas. However, two recent studies in Copeia split the arapaimas into at least five total species—and more may be coming.
98% of marine fish headed for the aquarium trade die within a year in the Philippines
(10/22/2013) Almost all wild caught marine fish for the aquarium trade will die within a year of capture, according to WWF. Following months of interviews with Filipino marine exporters and hobbyists, WWF-Philippines have found that roughly 80% of all marine fish die before they are sold, and those that survive long enough to be bought by hobbyists are extremely likely to be dead in under a year.
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.
Another 'sea-serpent' oarfish washes up in California
(10/20/2013) Another sea-serpent-like oarfish has been found dead along the coast in Southern California
California 'sea monster' is an oarfish
(10/16/2013) The dead "sea monster' spotted off the coast of Southern California on Sunday is actually an oarfish, a deepwater fish species that can reach a length of 55 feet (17 meters).
Pet fish invade ecosystem, upending nutrients and impoverishing fishers
(10/02/2013) If you, or someone you know, owns a freshwater aquarium, chances are you have seen the peculiar little creature attached face-first to the glass in effort to find a morsel of algae. This algae eater, popularly known as the sucker fish, is the sailfin catfish, or plecos. It is one of the most commonly purchased fish in the freshwater aquarium fish trade, and, according to recent research in The Royal Society B, aquarists often reintroduce the sucker-fish into the wild with detrimental consequences.
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.
New campaign celebrates the world's 'ugliest' animal
(09/16/2013) The blobfish (Psychrolutes marcidus), a species that lives at great depths and is rarely seen but resembles a marine Jabba the Hut, has been voted the world's ugliest animal.
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.
Video: scientists discover new walking shark species in Indonesia
(09/11/2013) A species of shark that uses its fins to 'walk' along the bottom of the ocean floor has been discovered off the coast of Indonesia. The shark, Hemiscyllium halmahera, uses its fins to wiggle along the seabed and forage for small fish and crustaceans, scientists from Conservation International said on Friday.
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.
Trinidad and Tobago: a biodiversity hotspot overlooked
(08/26/2013) The two-island nation of Trinidad and Tobago in the Caribbean (just off the coast of Venezuela) may be smaller than Delaware, but it has had an outsized role in the history of rainforest conservation as well as our understanding of tropical ecology. Home to an astounding number of tropical ecosystems and over 3,000 species and counting (including 470 bird species in just 2,000 square miles), Trinidad and Tobago is an often overlooked gem in the world's biodiversity.
Endangered chimps and forest elephants found in rainforest to be logged for palm oil
(08/08/2013) A biological survey of forests slated for destruction for a palm oil project in Cameroon has uncovered 23 species of large mammals, including the world's most endangered chimpanzee subspecies, the Nigeria-Cameroon chimpanzee (Pan troglodytes ellioti). The project in question, operated by U.S.-based company Herakles Farms, has come under stiff criticism both locally and abroad for threatening one of Africa's most biologically rich forest lands and arguably undercutting local peoples' access to traditional lands.
Rare and threatened freshwater fish plundered for aquarium trade in India
(07/25/2013) Thirty percent of the fish exported from India in the past seven years were from dozens of threatened species including the endangered red-lined torpedo barb (Puntius denisonii) and the miss kerala look alike (Puntius chalakkudiensis) amongst others, according to a recently published paper in Biological Conservation. By documenting the extent and impact of the trade in rare and threatened freshwater fish species in India, scientists have uncovered the local scale of the aquarium pet trade.
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?
Tiny suckermouth catfish discovered in Brazil
(07/10/2013) Scientists have discovered a new suckermouth catfish in the Rio Paraíba do Sul basin in southeastern Brazil.
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.
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.
China approves another mega-dam that will imperil endangered species
(05/21/2013) Chinese environmental authorities have approved construction plans for what could become the world's tallest dam, while acknowledging that the project would affect endangered plants and rare fish species.
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.
Aquarium launches desperate search to save a species down to 3 individuals
(05/10/2013) Aquarists at ZSL London Zoo have launched a worldwide appeal to find a female mate for a fish species that is believed to have gone extinct in the wild.
Scientists discover that marine animals disperse seagrass
(05/09/2013) Lesser known than coral reefs, marine seagrass ecosystems are rich in biodiversity and are powerhouses when it comes to sequestering carbon dioxide. Yet, much remains unknown about the ecology of seagrass beds, including detailed information on how seagrass spread their seeds and colonize new area. Now a recent study in Marine Ecology Progress Series documents that several species of marine animal are key to dispersing seagrass, overturning the assumption that seagrass was largely dispersed by abiotic methods (such as wind and waves).
Frankenfish or scientific marvel?: giant GM salmon await U.S. approval
(05/07/2013) It is hard to think of a more unlikely setting for genetic experimentation or for raising salmon: a rundown shed at a secretive location in the Panamanian rainforest miles inland and 1,500m above sea level. But the facility, which is owned by an American company AquaBounty Technologies, stands on the verge of delivering the first genetically modified food animal—a fast-growing salmon—to supermarkets and dinner tables.
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.
Clownfish helps its anemone host to breathe
(04/24/2013) The sight of a clownfish wriggling through the stinging tentacles of its anemone is a familiar and seemingly well-understood one to most people—the stinging anemone provides a protective home for the clownfish who is immune to such stings, and in turn the clownfish chases away any polyp-eating sunfish eyeing the anemone's tentacles for a meal. But recent research has shown that all that clownfish wriggling significantly helps to oxygenate the anemone at night, when oxygen levels in the water are low.
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.
Future generations to pay for our mistakes: biodiversity loss doesn't appear for decades
(04/15/2013) The biodiversity of Europe today is largely linked to environmental conditions decades ago, according to a new large-scale study in the Proceedings of the National Academy of Sciences (PNAS). Looking at various social and economic conditions from the last hundred years, scientists found that today's European species were closely aligned to environmental impacts on the continent from 1900 and 1950 instead of more recent times. The findings imply that scientists may be underestimating the total decline in global biodiversity, while future generations will inherit a natural world of our making.
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.
Scientists describe new species of see-through fish from the Amazon
(04/03/2013) Scientists have documented an entirely new genus of fish from the Amazon rainforest.
Fish use adoption strategy to ensure survival of young
(03/20/2013) Fish in southern Africa's Lake Tanganyika engage in adoption as a risk mitigation strategy for keeping some of their offspring from being eaten, finds a new study published in the journal Behavioral Ecology.
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.
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.
This is a test
(01/01/2013) Part of it was environmental education at a young age. The other part was going to Punjab when I was young and seeing, basically, the trees didn’t look like the trees I saw growing up in the United States. The land really looked like it was stripped of a lot of its natural beauty. There weren’t birds. A lot of the wildlife described in the Guru Granth Sahib [Sikh scriptures] isn’t there anymore. Something had really been taken, something had been removed from this land that I felt was such a piece of what [the land] was — in my own understanding, through my family’s knowledge, through the Guru Granth Sahib. That’s when I really started to think, this is the issue I want to work on for the rest of my life.
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.
