Shark-Repellent Metal Alloys Available For Sale; 'Able To Reduce Shark Bycatch'

KEY WEST, Florida -- SharkDefense Technologies and HEFA Rare Earth Canada, Co. Ltd. announced today that shark-repellent metal alloys are available for sale. The metal alloys are proven to reduce the accidental capture of sharks and are anticipated to benefit many commercial fishing operations.

The shark-repellent metal alloys work by generating a small voltage in seawater, which affects a shark's electric sense. Bony fish, such as tuna, do not have the organ responsible for the electric sense and are unaffected by the metals. While conducting experiments with magnets in 2006, SharkDefense discovered the shark-repelling effects of the metal alloys. The alloys induced repellent responses on sharks which were similar to those effects induced by the magnets.

Craig O'Connell, a partner with SharkDefense who has participated in the repellent trials pointed out that "through extensive testing on a variety of species of sharks, it is evident that these metals induce repellent responses which will allow fisherman to focus their effort on target species."

Application of the metal alloy repellent simply requires a small piece of metal to be secured near the bait at each hook. Continuously submerged in salt water, the metals last for up to 48 hours.

Dr. Patrick Rice, Director of Marine Science at Florida Keys Community College, carefully monitors the development of shark repellent technologies and advises that a number of recent "repellent tests performed by marine fisheries scientists and independent scientists confirm that these metals are able to reduce shark bycatch."

The suicidal tendencies of the Turkish tuna fishery

Karaburun, Turkey — The Turkish government has set its own catch limit for the endangered Mediterranean bluefin tuna - in total disregard for internationally agreed quotas and scientific advice.

The existing management plan for bluefin tuna is bad enough. By pressuring politicians to ignore the warnings of scientists, the Mediterranean tuna industry has created a suicide pact, not a management plan. Now Turkey, by objecting to even those inadequate restrictions, is telling its legal fleet to fish for everything it can before it's all gone. And to add insult to absurdity, there's still the illegal catch to consider -- and Turkey just got caught red-handed with an illegal landing of between 5 and 10 tonnes of juvenile bluefin tuna in the Turkish port of Karaburun. And this year's bluefin tuna fishing season is only just getting started!

Turkey currently operates the largest Mediterranean fleet fishing for bluefin tuna, an economically and ecologically valuable species facing imminent collapse as direct result of overfishing. Northern bluefin tuna have long been an important part of the Mediterranean economy and way of life. In ancient Rome, tuna fishing and salting were two of the empire’s most stable industries. Today, virtually all bluefin tuna from the Mediterranean is exported to Japan creating vast profits over the last decade, which have fuelled an industry with no concern for the future of a species that has been reduced to critical levels, threatening its own future and those of hundreds of fishermen.

An international disgrace
Management of bluefin tuna is entrusted to the International Commission for the Conservation of Atlantic Tunas (ICCAT), an intergovernmental organisation in which the European Union is an active and influential member. In September 2008, an independent performance review of ICCAT noted that the management of the bluefin tuna fishery in the Mediterranean was “widely seen as an international disgrace.” The Turkish government objected to the bluefin tuna quota that was agreed upon at the ICCAT meeting last November.

The last goodbye
Alongside ICCAT quotas, a minimum legal landing size is set at 30 kg to allow for at least one reproduction cycle before any catch. But catches below this limit have recently been reported by both Turkish and Italian media. Ignoring international quota limits means that Turkey will bring an end to the bluefin tuna business even faster through the commercial extinction of the species.

Since 2006, scientists have been sounding the alarm on the dire state of the bluefin tuna stock. They have advised not to fish above a maximum of 15,000 tonnes, and to protect the species’ spawning grounds during the crucial months of May and June. But the spawning grounds are ravaged by industrial fleets every year and the actual haul has been estimated at a shocking 61,100 tonnes in 2007, twice the legal catch for that year, and more than four times the scientifically recommended level. This year, a so called ‘recovery plan’ for bluefin tuna will legally allow fishing that is 47 percent above the maximum sustainable limit.
No fish, no future

Turkey, and all other fishing nations including European countries, should close the bluefin fishery immediately until management is in strict compliance with the scientific advice, fishing has decreased to sustainable levels and marine reserves are established to protect the bluefin breeding grounds.

Many conservation organization have documented at sea, and compiled numerous cases of illegal fishing in the Mediterranean, including fishing during closed seasons, catches of undersized tuna, illegal reflagging of fishing vessels, illegal use of spotter planes, unlicensed fishing vessels and tuna farms, unregulated transhipments, illegal landings and false declarations, substantial unreported over-catches and further increase of fishing fleet capacity. Since the fishing industry is now completely out of control and leading the bluefin tuna to near-extinction.

Conservationists are advocating the creation of a network of no-take marine reserves, protecting 40 percent of the world’s oceans, as the long term solution to the overfishing of tuna and other species, and the recovery of our overexploited blue planet.

THE END OF THE LINE

The End of the Line, the first major feature documentary film revealing the impact of overfishing on our oceans. Filmed over two years, we see firsthand the effects of our global love affair with fish as food. The film examines the imminent extinction of bluefin tuna, brought on by increasing western demand for sushi; the impact on marine life resulting in huge overpopulation of jellyfish; and the profound implications of a future world with no fish that would bring certain mass starvation.

The Film

The world’s first major documentary about the devastating effect of overfishing premiered at Sundance Film Festival. Tickets for preview screenings at UK cinemas on World Oceans Day – Monday 8 June, now available from www.endoftheline.com/things_to_do/screenings

Imagine an ocean without fish. Imagine your meals without seafood. Imagine the global consequences. This is the future if we do not stop, think and act.

The End of the Line, the first major feature documentary film revealing the impact of overfishing on our oceans, had its world premiere at the Sundance Film Festival in the World Cinema Documentary Competition. Sundance took place in Park City, Utah, January 15-25, 2009.

In the film we see firsthand the effects of our global love affair with fish as food.

It examines the imminent extinction of bluefin tuna, brought on by increasing western demand for sushi; the impact on marine life resulting in huge overpopulation of jellyfish; and the profound implications of a future world with no fish that would bring certain mass starvation.

Filmed over two years, The End of the Line follows the investigative reporter Charles Clover as he confronts politicians and celebrity restaurateurs, who exhibit little regard for the damage they are doing to the oceans.

One of his allies is the former tuna farmer turned whistleblower Roberto Mielgo – on the trail of those destroying the world's magnificent bluefin tuna population.

Filmed across the world – from the Straits of Gibraltar to the coasts of Senegal and Alaska to the Tokyo fish market – featuring top scientists, indigenous fishermen and fisheries enforcement officials, The End of the Line is a wake-up call to the world.

The end of seafood by 2048

Scientists predict that if we continue fishing as we are now, we will see the end of most seafood by 2048.

The End of the Line chronicles how demand for cod off the coast of Newfoundland in the early 1990s led to the decimation of the most abundant cod population in the world, how hi-tech fishing vessels leave no escape routes for fish populations and how farmed fish as a solution is a myth.

The film lays the responsibility squarely on consumers who innocently buy endangered fish, politicians who ignore the advice and pleas of scientists, fishermen who break quotas and fish illegally, and the global fishing industry that is slow to react to an impending disaster.

The End of the Line points to solutions that are simple and doable, but political will and activism are crucial to solve this international problem.

We need to control fishing by reducing the number of fishing boats across the world, protect large areas of the ocean through a network of marine reserves off limits to fishing, and educate consumers that they have a choice by purchasing fish from independently certified sustainable fisheries.

The Science

Overfishing in 2009, by Charles Clover

Overfishing was recognised as one of the world's greatest and most immediate environmental problems in 2002, when it was first demonstrated that global catches of wild fish had peaked around 1989 and have since been in decline.

Globally, some 75 per cent of wild marine fish are now said to be either fully-exploited or overfished, according to the United Nations' Food and Agriculture Organisation (UN FAO). That means these species require conservation and management in order to survive in their present numbers - which they rarely receive.

The number of fish stocks recorded as fully or overfished worldwide is expected to increase significantly this year when the latest figures are published by the UN FAO.

The fish species in the worst shape are highly migratory oceanic sharks; fish that are exploited fully or partially on the high seas, such as the larger tunas; and shared stocks, such as the Patagonian toothfish or Chilean sea bass.

Aquaculture, or fish farming, now provides almost half of all the fish consumed by humans. In the West – but not in Asia - it is mostly carnivorous fish that are farmed. The growth of aquaculture has slowed as stocks of small fish used to feed larger fish are themselves overfished.

The North East Atlantic, which includes EU waters, is one of the worst areas in the world for overfishing – along with the western Indian Ocean and the North West Pacific, according to the UN FAO.

In European waters, some 80 per cent of stocks are recorded as overfished, according to the European Commission.

In UK waters, stocks of palatable fish, such as cod, have been reduced to less than 10 per cent of what they were 100 years ago. This compares with a global average of 25 per cent of stocks actively overfished.

The nation with the least overfishing problem is New Zealand, where only 15 percent of stocks are recorded as overfished. The problem is that in Europe some 50 per cent of the quotas set by politicians are higher than scientists say are sustainable.

The EU was instrumental in arguing for a quota of 22,000 tons of valuable bluefin tuna for next year at a meeting of the International Commission for the Conservation of Atlantic Tunas in Marrakech in November, even though scientists recommended a quota of only 15,000 tons to avert stock collapse.

The United States had called for a total ban on catching bluefin in the Mediterranean to allow stocks to recover from rampant overfishing, both illegal and legal.

The bleak future predicted for the sea by some scientists already exists in British waters, where in places overfishing has resulted in a simplified ecosystem vulnerable to total collapse.

In the Firth of Clyde, near Glasgow, the cod, haddock, saithe, brill and whiting have all been overfished. All there remains for fishermen to catch is Norway lobster, also known as

langoustine or scampi.

In the absence of cod, which eat diseased Norway lobsters, some 70 per cent of Norway lobsters are now afflicted by the parasite-borne ailment known as smoking crab disease.

Prospects for the Clyde fishermen are not good.

The Campaign

The End of the Line is not against fishing. It is not against eating fish. But it is for a responsible attitude towards the oceans.

The film has three messages for consumers, citizens and companies:

Ask before you buy:

only eat sustainable seafood.

Tell politicians:

respect the science, cut the fishing fleet

Join the campaign

for marine protected areas and responsible fishing

We hope that when people buy fish in a shop or in restaurant, they will ask where it comes from; whether it is from a sustainable source, whether it is an endangered or over-exploited species.

There are useful guides to what fish you can buy with a (fairly) clear conscience. In the UK one is produced by the Marine Conservation Society. You can find the guide on their website.

And the Marine Stewardship Council runs a certification scheme for fish produced according to principles of sustainability, which you can find out about on the MSC website

But we also want people to put pressure on politicians to listen to the scientists and act upon their recommendations. Write to your representative. Sign up to the Pledges.

And, finally, join the campaign to make more of the oceans protected areas, where industrial

fishing is not allowed and where fish stocks can replenish themselves.

At the moment only 3 per cent of the world's oceans are marine protected areas.

You can learn more about why they should be increased and those who are campaigning for them, on the websites on the Organizations page.

World Leaders and Organizations Speak Out on Overfishing

"Once considered inexhaustible, our oceans are now in a state of global crisis as more and more people compete for fewer and fewer fish. Overfishing threatens coastal communities and the food security of the millions who rely on marine fish as an important source of protein. Yet the solutions are in our hands, because what we buy for dinner tonight can determine whether tomorrow's generations will continue to enjoy the oceans' riches. Or not." WWF, the global conservation organization

"The vibrant beauty of the oceans is a blessing to our country. And it’s a blessing to the world. The oceans contain countless treasures. They carry much of our trade; they provide food and recreation for billions of people. We have a responsibility, a solemn responsibility, to be good stewards of the oceans and the creatures who inhabit them." President George W. Bush

"We know that when we protect our oceans, we’re protecting our future." President Bill Clinton

Prince Charles, who is president of the MCS, said it was a "wake-up call" that British seas were in need of urgent help. "There is simply nowhere in Britain's seas where marine life is effectively protected from human impacts," he said. "Never has it been so important to take immediate action to protect marine life." HRH Prince Charles, President, Marine Conservation Society

"The need for nations to agree on urgent action has never been more acute. Measures introduced over the next few years will determine what the future will hold in terms of food security, species survival and the ocean’s ability to withstand climate change, and those measures have to include a robust network of marine protected areas, in national and international waters." Carl Gustaf Lundin, Head of the IUCN Global Marine Programme, United Nations General Assembly, World Conservation Union

"After climate change, commercial fishing represents the greatest threat to life in our oceans. As well as ruthlessly fishing out stock after stock, the way we fish has disastrous consequences for other species and entire ecosystems – but the damage being done is out at sea, out of sight, and out of mind for most people. We need to take drastic action to repair the damage we’ve done to our oceans before it’s too late." Willie Mackenzie, Oceans Campaign, Greenpeace United Kingdom

"Overfishing cannot continue." Nitin Desai, Secretary General of the 2002 World Summit on Sustainable Development

''We've acted as if the supply of fish was limitless and it's not." Steve Trent, Executive Director, Environmental Justice Foundation

''As Europe has sought to manage its fisheries and to limit its fishing, what we've done is to export the overfishing problem elsewhere, particularly to Africa." Steve Trent, Executive Director, Evironmental Justice Foundation

''The sea is being emptied." Moctar Ba, Scientific Consultant, Mauritania and West Africa

"Can the sea really let us eat sushi in these numbers?" Caroline Bennett, Founder, Moshi Moshi sushi chain

"This project allows us to finally start to see the big picture of how humans are affecting the oceans. Our results show that when these and other individual impacts are summed up, the big picture looks much worse than I imagine most people expected. It was certainly a surprise to me." Ben Halpern, U.S. National Center for Ecological Analysis and Synthesis (NCEAS)

"It is true that fishermen feel an almost desperate need to catch as many fish as they can when they're allowed to. That sense of desperation ... can't be an excuse for the policymakers of the world and this country to allow that to cause the universal collapse of fisheries." James Greenwood, former U.S. Congressman

"Never before have Mediterranean countries had more reason or opportunity to safeguard the region's beleaguered sharks and rays. Officials should heed the dire warnings of this report and act to protect threatened sharks and rays through regional fisheries agreements, international wildlife conventions, and national legislation. Such action is necessary to change the current course toward extinction of these remarkable animals." Sonja Fordham, deputy chairman of the SSG and policy director for the Shark Alliance

"An estimated 40 percent of cod caught in the Baltic Sea are illegal." Mireille Thom, spokeswoman for Joe Borg, European Union Commissioner of Fisheries and Maritime Affairs
