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.
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.
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.
Pictures of the day: sea turtle and whale shark release in China
(07/18/2012) Earlier this month, Sea Turtles 911, a conservation organization in China, released two green sea turtles (Chelonia mydas) and a juvenile whale shark (Rhincodon typus) back into the wild.
Clever whale shark video goes viral
(07/17/2012) Researchers have a caught a juvenile—though still massive—whale shark on camera sucking fish out of a hole in an Indonesian fishing net. Posted on YouTube.com, the video has gone viral and has been viewed by 1.2 million people to date. The footage was captured during a program to tag 30 whale sharks (Rhincodon typus) in Indonesia's Cendrawasih Bay National Marine Park in order to learn more about the world's largest fish.
Bad science journalism: articles spread misinformation about whale sharks
(07/09/2012) The death of one of the world's largest recorded whale sharks (Rhincodon typus) in the Arabian Sea provoked a sudden global interest in these massive shark. Weighing 14.5 tons, the fish in question made 'whale shark 'whale shark' the number 3 top search in Google Trends on the day the news hit. But, according to a new study in mongabay.com's open access journal Tropical Conservation Science, more than half the reports filed by journalists were "factually wrong."
Genetic analysis reveals 79 new species of sharks and rays, many likely endangered
(06/27/2012) Analyzing the DNA sequences of 4,383 specimens of sharks and rays, researchers have discovered 79 potentially new species, raising both the known diversity of this predacious family and concerns that many species are likely more imperiled than thought. Already 32 percent of open ocean sharks and rays are considered threatened with extinction by the IUCN Red List, due largely to overfishing, finning, bycatch, and prey depletion.
Manta rays tracked by satellite
(05/11/2012) Satellite tracking technology has revealed new insights into the behavior of manta rays, reports the Wildlife Conservation Society (WCS). The findings are published in this week's issue of the journal PLoS.
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.
Top 10 Environmental Stories of 2011
(12/22/2011) Many of 2011's most dramatic stories on environmental issues came from people taking to the streets. With governments and corporations slow to tackle massive environmental problems, people have begun to assert themselves. Victories were seen on four continents: in Bolivia a draconian response to protestors embarrassed the government, causing them to drop plans to build a road through Tipnis, an indigenous Amazonian reserve; in Myanmar, a nation not known for bowing to public demands, large protests pushed the government to cancel a massive Chinese hydroelectric project; in Borneo a three-year struggle to stop the construction of a coal plant on the coast of the Coral Triangle ended in victory for activists; in Britain plans to privatize forests created such a public outcry that the government not only pulled back but also apologized; and in the U.S. civil disobedience and massive marches pressured the Obama Administration to delay a decision on the controversial Keystone XL pipeline, which would bring tar sands from Canada to a global market.

California governor signs ban on shark fin trade
(10/10/2011) California governor Jerry Brown on Friday signed legislation banning the the importation, possession and sale of shark fins in California.
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.
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.
Left alive and wild, a single shark worth $1.9 million
(05/02/2011) For the Pacific island nation of Palau, sharks are worth much more alive than dead. A new study by the Australian Institute of Marine Science (AIMS) has found that one reef shark during its full life is worth $1.9 million to Palau in tourism revenue. Sold for consumption the shark is worth around $108. In this case a shark is worth a stunning 17,000 times more alive than dead.
California proposes ban on selling shark fin
(02/16/2011) Last year Hawaii banned the sale of shark fins; California may be next. Bill 376, introduced by two Democrats, would outlaw the sale of shark fins, including the popular Asian delicacy shark fin soup, in the US's most populous state.

Massive shark sanctuary declared in the Coral Triangle
(11/17/2010) A shark sanctuary has been declared around the Raja Ampat islands in Indonesia. Larger than Denmark, the new sanctuary covers 17,760 square miles (46,000 square kilometers) of one of the world's richest marine biodiverse region, the Coral Triangle. Protections not only cover sharks, but dugongs, marine turtles, mobulas, and manta rays as well. In addition, reef bombing and fishing for the aquarium trade are banned.
What do wolves and sharks have in common?
(11/15/2010) Sharks dwell in the ocean, wolves on land; sharks are a type of fish, wolves are a mammal; sharks go back some 400 million years, wolves only some 2 million years. So, these animals should have little in common, right? However, a new study in Frontiers in Ecology and the Environment points to surprising similarities among these disparate animals. As top predators, both wolves and sharks impact their prey and other species in similar ways.
Island nation announces Ukraine-sized sanctuary for whales and dolphins
(10/24/2010) Dolphins, whales, and dugongs will be safe from hunting in the waters surrounding the Pacific nation of Palau. At the Convention on Biological Diversity (CBD) in Nagoya, Japan, Palau's Minister of the Environment, Natural Resources and Tourism, Harry Fritz, announced the establishment of a marine mammal sanctuary covering over 230,000 square miles (60,000 square kilometers) of the nation's waters, an area the size of Mongolia.
Shark attack victims: save sharks!
(09/13/2010) Shark attack survivors urged the United Nations to take measures to protect sharks, which are increasingly threatened by unsustainable fishing practices.
Coral reef survival depends on the super small, an interview with Forest Rohwer
(08/30/2010) If you take a teaspoon and dip it into the ocean what will you have? Some drops of lifeless water? Only a few decades ago this is what scientists would have said, however, the development of increasingly powerful microscopes have shown us a world long unknown, which has vital importance for the survival of one of the world's most threatened and most treasured ecosystems: coral reefs. A single milliliter of water is now known to contain at least a million living microbes, i.e. organisms too small to see without a microscope. After discovering their super-abundant presence, researchers are now beginning to uncover how these incredibly tiny life-forms shape the fate of the world's coral reefs.
The biology and conservation of declining coral reefs, an interview with Kristian Teleki
(08/15/2010) Coral reefs are often considered the "rainforests of the sea" because of their amazing biodiversity. In fact, coral reefs are one of the most diverse ecosystems on earth. It is not unusual for a reef to have several hundred species of snails, sixty species of corals, and several hundred species of fish. While they comprise under 1% of the world’s ocean surface, one-quarter of all marine species call coral reefs their home. Fish, mollusks, sea stars, sea urchins, and more depend on this important ecosystem, and humans do too. Coral reefs supply important goods and services–from shoreline protection to tourism and fisheries–which by some estimates are worth $375 billion a year.
Citibank's shark fin soup promotion draws ire, ends early
(07/22/2010) Citibank Hong Kong has canceled its promotion of shark fin soup after activists cried foul, according to the New York Times. The branch had offered Citibank card holders 15 percent off a shark fin soup dinner at Maxim's Chinese Cuisine for the month of July.
Hawaii bans shark fin soup
(05/31/2010) Governor of Hawaii, Linda Lingle, has signed into law a ban on shark-fin soup beginning July 1st, 2011, according to Reuters. The soup is currently served in a number of Chinese restaurants in Hawaii, but the trade has decimated certain shark species due to overfishing.
World failing on every environmental issue: an op-ed for Earth Day
(04/22/2010) The biodiversity crisis, the climate crisis, the deforestation crisis: we are living in an age when environmental issues have moved from regional problems to global ones. A generation or two before ours and one might speak of saving the beauty of Northern California; conserving a single species—say the white rhino—from extinction; or preserving an ecological region like the Amazon. That was a different age. Today we speak of preserving world biodiversity, of saving the 'lungs of the planet', of mitigating global climate change. No longer are humans over-reaching in just one region, but we are overreaching the whole planet, stretching ecological systems to a breaking point. While we are aware of the issues that threaten the well-being of life on this planet, including our own, how are we progressing on solutions?
History repeats itself: the path to extinction is still paved with greed and waste
(04/05/2010) As a child I read about the near-extinction of the American bison. Once the dominant species on America's Great Plains, I remember books illustrating how train-travelers would set their guns on open windows and shoot down bison by the hundreds as the locomotive sped through what was left of the wild west. The American bison plunged from an estimated 30 million to a few hundred at the opening of the 20th century. When I read about the bison's demise I remember thinking, with the characteristic superiority of a child, how such a thing could never happen today, that society has, in a word, 'progressed'. Grown-up now, the world has made me wiser: last month the international organization CITES (Convention on International Trade in Endangered Species) struck down a ban on the Critically Endangered Atlantic bluefin tuna. The story of the Atlantic bluefin tuna is a long and mostly irrational one—that is if one looks at the Atlantic bluefin from a scientific, ecologic, moral, or common-sense perspective.
CITES chooses 'commerce' over sharks, leaving endangered species vulnerable
(03/23/2010) Only the porbeagle shark received protection today from the Convention on International Trade in Endangered Species (CITES). Seven other shark species failed to win international protection despite plummeting populations due to overfishing. Once again, Japan led the opposition to regulating the trade in white-tipped sharks and scalloped hammerheads, including two look-alike species: the great hammerhead and the smooth hammerhead. Japan has dominated the CITES meeting, successfully leading resistance to banning the trade in the Critically Endangered Atlantic bluefin tuna and against monitoring the coral trade.
Sharks lose out at UN meeting
(03/17/2010) An effort to bolster conservation measures for plummeting shark populations was defeated yesterday at the Convention on International Trade in Endangered Species (CITES), according to the AP. The nonbinding measure would have increased transparency in the shark trade and produced research on illegal fishing for sharks.
Sharks swim safe around the Maldives
(03/11/2010) Sharks that dwell in the Maldives can breathe a sigh of relief: the island nation has declared 90,000 square kilometers of the Indian Ocean a safe-haven for sharks, banning shark fishing as well as any trade in shark fins.
With increased protection, Gulf of California marine life could recover
(02/22/2010) The Gulf of California's once rich marine ecosystem is in trouble. Surveys from 1999 and 2009 revealed that during the ten-year-period 60 percent of the areas showed signs of degradation, including the loss of top predators necessary to keep an ecosystem healthy, for example sharks, groupers, and snappers.
UN to protect seven migratory sharks, but Australia opts out
(02/17/2010) One hundred and thirteen countries have signed on to an agreement to protect seven migratory sharks currently threatened with extinction byway of the Convention on the Conservation of Migratory Species of Wild Animals (CMS), according to the UN Environment Program (UNEP). The agreement prohibits hunting, fishing, or deliberate killing of the great white shark, basking shark, whale shark, porbeagle shark, spiny dogfish, as well as the shortfin and longfin mako sharks. However, Australia has declared it will ignore certain protections.
Actions taken to save sharks 'disappointing'
(11/15/2009) Environmentalists say that the International Commissions for the Conservation of Atlantic Tuna (ICCAT) did not do enough in their yearly meeting to protect the ocean's sharks.
California's great white sharks are a distinct population
(11/04/2009) Researchers have long thought that white sharks migrated across oceans, but a new study in the Proceedings of the Royal Society B shows that the population in the northeastern Pacific Ocean, along California, hasn't mixed with other white sharks for tens of thousands of years.
New species of ghostshark discovered off California's coast
(09/22/2009) The discovery of Eastern Pacific black ghostshark Hydrolagus melanophasma is notable for a number of reasons. It is the first new species of cartilaginous fish—i.e fish whose skeletons are made entirely of cartilage, such as sharks, rays, and skate—to be described in California water since 1947. It is also a representative of an ancient and little-known group of fish.
20-foot-long washes up on New York beach
(07/15/2009) A 20-foot-long, 5,000 pound basking shark washed up on a Long Island beach yesterday, reports CNN.
Over 30 percent of open ocean sharks and rays face extinction
(06/25/2009) The first global study of open ocean (pelagic) sharks and rays found that 32 percent of the species are threatened with extinction largely due to overfishing and bycatch, making pelagic sharks and rays more threatened than birds (12 percent), mammals (20 percent), and even amphibians (31 percent), which are considered to be undergoing an extinction crisis. The situation worsens when only sharks taken in high-seas fisheries are considered: 52 percent of these species are threatened.
Secret movements of the basking shark uncovered
(05/07/2009) Researchers with the Massachusetts Mariner Fisheries have uncovered the secret life of the world’s second largest fish, known for its cavernous mouth. The basking shark, which measures over 10 meters and weighs as much as seven tons, has long baffled scientists by disappearing from view half of every year. A new study from Current Biology found that the basking shark spends this time deep in the Atlantic’s tropical waters.
Whale sharks threatened by interbreeding
(04/08/2009) The world's largest living fish, the whale shark, is threatened by interbreeding, according to a new study in PLoS ONE. Comparing the DNA of 68 individual whale sharks from eleven locations across the globe, geneticists found that the whale sharks had little genetic variation between the populations.
Hundreds of rare and bizarre marine species discovered
(11/09/2008) The evolutionary origin of deep sea octopuses, new species populating an underwater "continent", 12,000 amphipods crowding a square meter in the Gulf of Mexico, massive gatherings of white sharks in the middle of the Pacific: these are just a few highlights from the Census of Marine Life (COML)'s fourth report.
Sharks in trouble after nations fail to create sustainable management programs
(11/06/2008) Sharks are disappearing from the ocean at startling rates: currently one-in-five of these famous marine predators are threatened with extinction. According to a report from the Australian Government and TRAFFIC—an organization that monitors wildlife trade both legal and illegal—the collapse of shark populations is being caused largely by rising demand for shark fin in Asia. The report shows that legal fishing for sharks has become nearly as detrimental as illegal, since few fisheries have management strategies concerned with sustainability.
The long-ignored ocean emergency and what can be done to address it
(08/18/2008) This year has been full of bad news regarding marine ecosystems: one-third of coral species threatened with extinction, dead-zones spread to 415 sites, half of U.S. reefs in fair or bad condition, increase in ocean acidification, tuna and shark populations collapsing, and only four percent of ocean considered pristine. Jeremy Jackson, director of the Scripps Center for Marine Biodiversity and Conservation at the University of California, San Diego, synthesizes such reports and others into a new paper, published in the journal Proceedings of the Naional Academy of Sciences, that boldly lays out the scope of the oceanic emergency and what urgently needs to be done.
Large shark populations fall 97% in the Mediterranean
(06/12/2008) Populations of some shark species in the Mediterranean have plunged by more than 97 percent over the past 200 years, report researchers writing in the journal conservation Biology. Several species are at risk of extinction.
