Shark conservation proposal defeated at UN meeting

From an Associated Press article by Michael Casey:

DOHA, Qatar — China, Japan and Russia helped defeat a U.S.-endorsed proposal at a U.N. wildlife trade meeting Tuesday that would have boosted conservation efforts for sharks, expressing concern it would hurt poor nations and should be the responsibility of regional fisheries bodies.

The opposition to the shark proposal came hours after the marine conservation group Oceana came out with a report showing that demand for shark fin soup in Asia is driving many species of these big fish to the brink of extinction.

The nonbinding measure, which called for increased transparency in the shark trade and more research into the threat posed to sharks by illegal fishing, had been expected to gain approval by a committee of the 175-nation Convention on International Trade in Endangered Species, or CITES.

But the United States, the European Union and other supporters were unable to muster the two-thirds majority needed after China, Russia, Japan and several developing countries argued that shark populations aren't suffering.

The decision could be a bad omen for a two-week meeting that will include much more controversial marine proposals, including banning the export of Atlantic bluefin tuna, which is popular with sushi lovers, and tightening the trade on eight shark species.

Whale sharks of Holbox


A description of a stunning video from Kip Evans:

The waters around Isla Holbox off Mexicos Yucatán Peninsula teem with plankton, a feast for giant whale sharks—10-meter giants that gather by the hundreds from June through September. These super-sized but toothless filter feeders are the core of a local tourism industry, but over-development could threaten this delicate balance. Dr. Sylvia Earle narrates.

Sharks killed for oil used in swine flu vaccine

From an article by James Owen on National Geographic:

Vaccines being made to protect people from swine flu may not be so healthy for threatened species of sharks.

That's because millions of doses of the pandemic H1N1/09 vaccine contain a substance called squalene, which is extracted from shark livers. (Get more swine flu facts.)

More commonly found in beauty products such as skin creams, squalene can be used to make an adjuvant, a compound that boosts the body's immune response.

The World Health Organization recommends adjuvant-based vaccines, because they allow drug makers to create doses that use less of the active component, increasing available supplies.

Olive oil, wheat germ oil, and rice bran oil also naturally contain squalene, albeit in smaller amounts. But for now squalene is primarily harvested from sharks caught by commercial fishers, especially deepwater species. (Related: "Tomato, Tobacco Plants Produce SARS Vaccine.")

"There are several very disturbing issues associated with use of shark-liver-oil squalene," said Mary O'Malley, co-founder of the volunteer-run advocacy group Shark Safe Network.

"The deepwater sharks targeted have extremely low reproductive rates, and many are threatened species."

For example, one supplier has dubbed the gulper shark the Rolls-Royce of squalene-producing sharks—but the gulper is listed as vulnerable on the International Union for Conservation of Nature's (IUCN's) Red List of Threatened Species, meaning the species faces a high risk of extinction.

Meet Utila's whalesharks

From the Web site of Deep Blue Utila:

Surprisingly not much is actually known about the world's largest fish. Whale sharks have recently become protected in Honduras and Utila is on their main migratory path. A scuba diving vacation with Deep Blue Utila will provide you with the opportunity of seeing and even snorkelling with these awesome creatures.

Our Utila Whale Shark Research Project over the next five years will provide new information to add to the slowly growing knowledge base. Photographs taken of the Utila whale sharks are being added to ECOCEAN, an international whale shark database. In 2007 a whale shark was tracked through three different countries, this is the first time this has happened anywhere in the world.

Meet the 84 identified Utila sharks here.

Swimming With The Sharks: Interview With Vivian Toro, One Of Stuart Cove's Female Shark Feeders

From an article posted on Underwater Times:

NASSAU, That Bahamas -- One of the few things you won’t see on the average person's resume, even dive resume, is 'Shark Feeder.' Yet everyday, one of Stuart Cove's dive staff does just that. Under the watchful eye of Stuart Cove and his senior Shark Adventure program leaders, Marc Taggart and Tohru Yamaguchi, a team of four women and three men (probably the largest shark feeding staff in the world) swim with, carefully feed and control the sharks every day off Nassau. In the coming months, we are going to interview some of our actual feeders and give you, our industry partners and friends, a snapshot into the life of actual shark feeders at Stuart Cove's Dive Bahamas.

Our interview is with Vivian Toro, of Puerto Rico. Vivian, . . . What do you hope your guests will take away from the feeding experience?

"I look at the afternoon (as shark dives are scheduled in the afternoons) as a whole experience. The shark feed takes about 30 minutes in the water, but I strive for making the whole trip experience a day to remember and try to educate our guests about how amazing the sharks really are. Truly these animals are at the top of the food chain in the ocean. However, many people think that our sharks are trained or somehow tame. They are anything but. However, they are also very misunderstood. Even though our guests get a small glimpse of how fierce a shark can be when they bite down on the bait and their teeth extend for a fraction of a moment, sharks need our protection. Once you have been in an “intimate” face-to-face experience, you can appreciate their beauty and the need to protect and preserve these amazing animals. That is what I hope our guests leave with at the end of the experience."

Rules for protecting whale sharks

From the Web site of Serious Diving:

The creation of the Whale Shark tourism industry in this area of Mexico [Isla Mujeres] was carefully designed to be eco-friendly and to provide protection for participants and the Whale Sharks themselves. Prices, season dates and rules are set by the controlling bodies and are strict and heavily enforced. Our tour services are fully licensed and adhere strictly to the rules. Violating the rules not only puts you in danger but also endangers the animals and their ability to sustain their habits.

If you decide to use another provider, be sure to verify that they comply with all rules listed [on the Web site]. The Mexican Army is charged with enforcing rules and can detain non-compliant boats who do not comply with the rules. We want everyone to have a fun, exciting and ultimately safe tour no matter which provider they choose.

DO NOT BOARD TOURS USING DIESEL ENGINES, THE RESIDUE HARMS THE WHALE SHARKS!

Beware of anyone offering you a price below the legal standard or who claims they will allow you to violate the rules below. No one wants to waste a day of their vacation or hard earned money with a spoiled trip.

Support your local tour operators by booking directly with them rather than with large tour operators!

Bahamas reserve protects marine life from resort developers

From an article by Juliet Eilperin in the Washington Post:

The Bahamas government has created a marine reserve off the island of North Bimini, preserving critical mangrove habitat and a shark nursery that had come under threat from a resort there.

The reserve, which will be protected from most fishing and other "extractive activities," is home to endangered species such as the Nassau grouper and the Bimini boa, as well as a vibrant nursery for lemon sharks.

The decision -- approved by the Bahamas cabinet Dec. 29 but announced last week -- is a setback for the Bimini Bay Resort and Marina, which has been clearing some of the island's mangroves to build a hotel, a golf course, a casino and two marinas, some of which have already been constructed.

Prime Minister Hubert Ingraham had initially considered establishing the reserve in the late 1990s, but his party lost power in 2002, and the development proceeded. Ingraham's party won back control in 2007.

Pronatura studies whale sharks

From a project description on the Web site of Pronatura:

The objective of this Project is to generate technical and scientific information that contributes to the sustainable development of the whale shark (as a touristic attraction) in the marine area of Yum Balam, Contoy.

The Flora and Fauna Protection Area of Yum Balam is located in the northeast of the Yucatan Peninsula, close to Contoy Island. These two areas are very important to the whale shark.

This species is legally protected nationally and internationally. The project works in an area that seems to have the most sightings of whale sharks in the world. In the year 2004, 173 individuals were spotted within the area of Holbox, while 162 were seen in Ningaloo, Australia, and only 47 in Belize.

The whale shark is now threatened because of the little knowledge there is about its habits, ecology and biology. This knowledge and the strategy adopted for its management can only be successfully achieved if they are contemplated on a world-wide scale, because while overexploitation for sale and illegal consumption of the whale shark’s fins happens mostly in Asia and South Africa, this affects the global population of the species. . . .

Shark protection

Oceana reports success on one front and asks for help on another:

When we told you that the Vermont Country Store was selling a cosmetic product known as "squalane"obtained from shark liver oil, thousands of you contacted the store. Thanks to you, they stopped selling the product. But WaveMakers didn't just flood the inbox of the Vermont Country Store, many of you also wrote to us -- furious about beauty care supplier Dr. Susan Lark and her enthusiastic promotion of products containing squalane from sharks. Well, you spoke up and we listened! We asked her nicely and made little progress. Now it's time to get Dr. Lark to change her ways. . . .

On her website, Dr. Lark touts squalane for its ability to help skin "maintain its moisture and elasticity." She goes on to say that "the very best source comes from deep-sea Centrophorus sharks that live in the clean, non-polluted waters of Tasmania."

If Dr. Lark is such a fan of squalane - she can find it in a much more abundant source: olives. I'm willing to bet that her customers would prefer using moisturizers from olives instead of sharks. . . .

Tell Dr. Lark she ought to leave deep-sea sharks alone. The health - and beauty - of our oceans depends on it.

Huge gatherings of whale sharks discovered in Gulf of Mexico

From an article by Jim Tharpe in The Atlanta Constitution:

Scientists have become increasingly convinced that huge gatherings of giant whale sharks occur with clockwork regularity in the northern Gulf of Mexico off the coasts of Mississippi and Louisiana.

Scientist Eric Hoffmayer, who is trying to unravel the mysterious “aggregations,” said that as many as 100 of the bus-sized sharks have been spotted feeding in clusters at three separate areas about 40 to 100 miles offshore.

“We have lots of reports of 30 or 50 animals in one place,” said Hoffmayer, a scientist with the University of Southern Mississippi’s Gulf Coast Research Laboratory in Ocean Springs, Miss. “They are obviously gathering for a reason. But right now we are not sure what that is, or how they know to show up at these spots.”

Whale sharks, a key attraction at the Georgia Aquarium, are the planet’s biggest shark and can grow to more than 45 feet long. They are generally solitary, ocean-roaming creatures. Nobody knows how many exist. But there are a handful of locations around the globe where the polka-dotted, filter-feeding sharks congregate in large numbers to feast on plankton or fish eggs.

The northern Gulf aggregations, which occur from June through September, would be a major new discovery if scientists can confirm that they are occurring at regular, predictable intervals.

Costa Rica congress recommends immediate closure of private docks to end shark finning

From a post on the Web site of Programa Restauracion de Tortugas Marinas (pretoma.org):

The Permanent Special Environment Commission of Costa Rica’s Congress issued a report yesterday titled: Investigation on Shark Finning in Costa Rica, File N°16.890.

In the Report, the Commission points out that the use of private docks for the landing of shark products by foreign fleets is legally inadmissible, a key issue for marine conservation and fisheries management, and recommends the immediate closure of these illegal landing sites.

We are very satisfied with the Report of the Permanent Special Environment Commission”, commented Randall Arauz, President of PRETOMA, a Costa Rican NGO that has led a battle against shark finning since 2001. “As we have denounced over and over again, the use of private docks for the landing of shark products by foreign fleets is illegal, and it is the main legal loophole used by foreign fleets to circumvent shark finning regulations”, added Arauz.

“The Costa Rican Fisheries Institute, the Direction of Customs and the Ministry of Public Transportations have all claimed over and over again, that due to the lack of public docks they are in the capacity of legally authorizing the use of private docks by the foreign fleet”, informed Jorge Ballestero, of PRETOMA. “However, the Costa Rican Congress has just confirmed what we have known for years, and it’s that neither Customs nor any other public entity is in the legal capacity of authorizing their use”, clarified Ballestero.

“In spite of the good news, we still can’t celebrate”, declared a cautious Miguel Gómez, Campaign Coordinator of PRETOMA. “Since January of 2006, the Constitutional Court ordered the aforementioned institutions to halt all landings at private docks that were not provided with public installations, an order that was seconded by the Comptrollership’s Court a year later, but they still fail to abide by the rulings. Will they finally abide this time?” Gómez asked himself.

Sharks Up Close, 2008

From the Web site of the Ocean Realm Society:

Based at the famous Shark Lab on Bimini Island in the Bahamas, Sharks Up Close is seven days of full-on shark activity. We will be in the water with sharks every day and last year our encounters included Blacknose sharks, Lemon sharks, Nurse sharks, Tiger sharks, Carribean Reef sharks and Bull sharks as well as Southern Stingrays and Eagle rays. The weeks activity is led by the legendary shark scientist ‘Doc’ Gruber, assisted by fisheries scientist Dean Grubbs, with father and son conservation team John and Sune Nightingale there to teach underwater photography and video. . . .

The trip is organised as a non-profit venture helping to support the research work of the Bimini Shark Lab and the conservation work of The Shark Trust.

By the end of this trip you will have had close encounters with lots of sharks, you will have learnt a huge amount about sharks and you should come away with some wonderful shark photos.

Numbers will be strictly limited to 14, with places allocated on a first come first served basis. It will require a 20% deposit to secure a place, with the balance payable one month before departure.

Costa Rica again allows shark finning

The Costa Rican government earlier imposed a de facto ban on shark finning, but it recently lifted the ban, according to PRETOMA:

(December 13, 2007 – SanJosé, Costa Rica)

Last Monday, December 10, INCOPESCA, Customs and the Ministry of Public Transportation MOPT, authorized, yet again, the use of private docks for the landing of fishery products by international flag vessels, in clear violationof the orders of the Constitutional Court, in the sense that the authorities must immediately halt their use in absence of pubic infrastructure. The first private dock to illegally receive landings by international flag vesselswas Fortuna del Pacífico.

“We aren’t really surprised by the behavior of our fishery authorities, as they have repeatedly shown a greater interest to protect the interests of the owners of the private docks rather than protect the public interest, which is their constitutional duty”, complained Randall Arauz, President of PRETOMA. “The Constitutional Court will have the last word, as it has long becomeevident that the Executive branch of our government is incapable of orderingthe fishery authorities to abide by the law at the private docks,” expressed Arauz.

“What concerns us most is to see what our authorities are capable of doing with the sole intent of favoring the illegal activities of these foreign flagged vessels at private docks, even openly lying to cover them up”, pointed out Jorge Ballestero, of PRETOMA. According to Ballestero, the Belize flagged vessel Dragon 28 had been waiting in Puntarenas for permission to land its products at the private docks for three weeks. “We requested an explanationfrom MOPT, because if the vessel couldn’t land, it had no business in Puntarenas, but their response and the Manifiesto de Carga was that the Dragon 28 wasn’t carrying fishery products, only basalt, and thus,it wasn’t going to land anything in Costa Rica.

According to the cited documents, the vessel was only granted permission to stay in Puntarenas due to mechanical problems and to supply provisions for the crew. However, at9:45 of December 10 of 2007 the Dragon 28 was caught on video landing tons of shark products. “At this moment we are requesting to know the identity of the public functionaries who allowed these illegal landings, and establish legal responsibilities for supplying false information to the civil society”, informed Ballestero.

The potential for illegal activities at private docks is enormous”,pointed out Miguel Gómez, Director of Campaigns of PRETOMA. “Just last January the Cambodian flagged vessel Dragon III visited Puntarenas, but this vessel is blacklisted by the Inter American Tropical Tuna Commission (IATTC) practicing illegal, un regulated and un reported fishing”, pointed outGómez. According to the vessel’s manifest, the Dragon III didn’t carry any fishery products either, only basalt. “Were they lying again?” “Were shark fins landed in the middle of the night, when no officers are present?”, Gómez asked himself. “The truth is that in the privacy of the docks, there is simply no way to know”, sentenced Gómez.

Two weeks without shark finning in Costa Rica

From the Web site of of Programa Restauración de Tortugas Marinas (PRETOMA):

Since November 13, in compliance with a mandate by the Constitutional Court, the Puntarenas Port Authority, by order of the Director of Navigation and Security of the Ministry of Public Transportation, has not authorized the arrival of international flag longline vessels at private docks in Puntarenas (Resolution CPP-2007-379). The Port Authority’s position is in response to an accusation of disobedience to the Constitutional Court’s ruling of February 3, 2006, (Case: 2006-1109), which ordered the Port Authority, the Costa Rican Fisheries Institute (INCOPESCA) and Customs Office of the Ministry of Treasury), to immediately halt the landing of these vessels on private docks that are not provided with public infrastructure. The accusation was presented by PRETOMA, in January of 2007, after the authorities had disobeyed the Constitutional Court order for a year.

“We are very satisfied with this victory, given the importance of compliance with national laws,” said Jorge Ballestero, of Programa Restauración de Tortugas Marinas (PRETOMA). “The landing of shark fins and other fishery products at the private docks of Puntarenas by international flag longline vessels is an illegal activity, and one which clearly favors activities like shark finning, given that in the privacy of these docks it is impossible to protect the public interest,” explained Ballestero.

PRETOMA has identified the use of private docks by international flag longline vessels to be the greatest loop hole that facilitates shark finning in Costa Rica. In fact, Articles 211 and 212 of the Customs Law orders the obligatory use of public docks by international flag fishing fleets. In spite of these laws, Costa Rica has continued to receive these landings at private docks, uninterruptedly, since 1998.

Since the adoption of this policy by the Port Authority two weeks ago, three international flagged longline vessels have attempted, without success, to land their products. All three vessels, the Dragon 28, the Conchita 8, Yu Long 6, sail under the flag of Belize, and are currently docked at the private docks. This situation, however, could be only temporary, given that the Ministry of the Treasury has expressed its dissatisfaction to the Constitutional Court regarding the recent ruling, and has petitioned the accusation of disobedience to be dropped, with the intention of prolonging the illegal use of private docks to land shark fins and other shark products.

Hard-to-swallow hooks save turtles in Latin America

From a Reuters article by John McPaul posted on Planet Ark:

PUNTARENAS, Costa Rica - Endangered sea turtles accidentally caught by fishermen off Latin American coasts usually die but innovative hooks that are too big to swallow are increasingly saving the reptiles' lives.

The use of circular-shaped hooks lets fishing crews more easily remove hooks from the mouths of loggerhead, leatherback and other turtles caught up in long lines meant to catch fish and prevents them from bleeding to death.

Four years ago, the World Wildlife Fund conservation group, or WWF, began encouraging long-line fishermen from Ecuador to Mexico to replace traditional J-shaped hooks, which fish and turtles tend to swallow, with various sizes of circular hooks.

Unlike the J-shaped hook that has its point parallel to the shaft, the circular hook points toward the shaft and is also wider, making it more likely that it will lodge in the lip rather than the throat or stomach, which is fatal, the WWF says.

The WWF believes close to 250,000 endangered turtles, as well as thousands of sea birds, sharks and sea mammals, are accidentally caught every year by long-line fishermen, who troll the ocean with lines strung with thousands of hooks.

Opportunities for shark research at Bimini Bahamas, 2007 and 2008

From the coral-list@coral.aoml.noaa.gov:

Volunteer positions at the Bimini Biological Field Station (Sharklab) will be available through the year starting in November 2007 through December 2008.

If you have a biological background or interest in shark biology and wish to join the research team either as a volunteer or project leader (PhD candidate or Post Doc)--for a minimum of one month--please contact Dr. Gruber at sgruber@rsmas.miami.edu with a copy to Kat Gledhill (Station Manager) at bbfssharklab@gmail.com. Please also visit our website at www.miami.edu/sharklab for details about the station, our research and courses.

For the coming season we are collaborating with marine biologists from universities in the US, UK and Canada and will be conducting field research on the population dynamics and behavior of young lemon sharks (*Negaprion brevirostris*) using long line collections, visual census, telemetry-tracking and monitoring as well as observation and experiments on captive animals. A second, continuing project concerning quantitative genetics and reproductive biology will involve intensive tagging and collection of DNA from the 2008 cohort of lemon sharks born at Bimini lagoon and elsewhere.

In addition to the Bimini site, lemon shark projects are underway at the Marquesas Keys, and Jupiter Florida. We are also hoping to continue our research on ecosystem dynamics of lemon shark nurseries including GIS and Ecopath analysis; and broaden our genetic studies. PhD candidates who have completed their course work are encouraged to contact us. Small stipends to cover some travel and living expenses in the Bahamas as well as equipment and supplies are available to successful candidates.

Cordially Yours,

Ecologists lash Ecuador for legalising shark-fin sales


From an article in the South African Mail & Guardian online:

Hundreds of sharks have been slaughtered daily off the coast of Ecuador since a ban on the sale of fins was lifted last week, prompting warnings of ecological disaster.

Fishing boats have returned to shore laden with fins of dozens of species, including several that are threatened with extinction, which are vital to maintaining biodiversity, according to critics.

The spectacle of fins piled up on piers has triggered a political row, pitting the government and fishermen against the rest of the country. Most of the fins are exported to Asia, where they end up in soup bowls.

"It is a big mistake. More than 400 sharks are being caught every day -- that damages the whole [food] chain," said Esperanza Martínez, of the advocacy group Ecological Action. Others say up to 1 000 are being caught.

Shark fishing remains illegal but President Rafael Correa legalised the sale of fins of sharks caught accidentally, saying the revenue would help impoverished fishermen to feed their families. However, with no clear way to determine whether a shark was caught accidentally or intentionally, the fishermen appear to regard the move as a green light to kill as many as they want in Ecuador's Pacific waters.

Why we can’t support shark week on Discovery


From the blog of MarineBio.org:

To the Discovery Network:

Members of our internet shark discussion forum, SHARK-L, have been asked by your marketing representatives to help promote your famous Shark Week sequence. This letter, signed by list members and friends, is our formal response to the request from your grassroots agency, New Media Strategies, for our support of the programming.

How can we support Discovery Channel when we are fighting for shark conservation, and its biggest obstacle is the monster image given to sharks by the media, including Shark Week programs? Further, some of us who have been directly involved in the production of your documentaries feel disgusted at the way that our interviews were censored and our words twisted around.
