The Shark Alliance was formed in 2006 in an attempt to streamline the efforts of NGOs involved in shark conservation. The Alliance is able to utilize the manpower, resources, and combined knowledge of its member organizations to more effectively lobby for sustainable European and global shark fishing limits. Members of the Shark Alliance include The Shark Trust, the European Elasmobranch Association, and The Ocean Concervancy, among others.
In its own words:
The Shark Alliance is a not-for-profit coalition of non-governmental organizations dedicated to restoring and conserving shark populations by improving European fishing policy. Because of the influence of Europe in global fisheries and the importance of sharks in ocean ecosystems, these efforts have the potential to enhance the health of the marine environment in Europe and around the world.
The mission of the Shark Alliance is two-fold: To close loopholes in European policy regarding the wasteful and unsustainable practice of shark finning; To secure responsible, science-based shark fishing limits for long-term sustainability and ecosystem health.
Sharks have evolved over 400 million years and play a critical role in ocean ecosystems. In common with land predators such as lions and wolves, sharks keep other marine populations in check and help maintain the balance of life in the sea. Today, primarily because of overfishing sharks are among the oceans’ most threatened animals. Tens of millions of sharks are killed each year, either intentionally or as bycatch in commercial and recreational fisheries. Ongoing assessment of the status of European sharks (and closely-related rays) by the IUCN (The World Conservation Union) has led to the classification of roughly one third of evaluated species as threatened (either Critically Endangered, Endangered or Vulnerable), with another 16 per cent at risk of becoming so in the near future. Sharks generally grow slowly, mature late and produce few young. Shark populations are therefore especially vulnerable to overexploitation and slow to recover once depleted. The loss of these important predators is predicted to have negative effects on many other species in the sea. Unfortunately, however, misinformation and fear all too often impede the public support required to ensure sharks receive management priority and conservation actions. Unlike many countries that fail to conserve sharks, Europe does not lack the resources to restrict fishing. Despite immediate threats facing sharks there are few European limits on shark fishing, and quotas are routinely set far in excess of actual catches. In 2003, the EU adopted a ban on shark finning (the wasteful practice of slicing off a shark’s fins and discarding the carcass at sea), but at the same time allowed glaring loopholes that render the ban all but meaningless. For instance, shark fishermen are allowed to land shark carcasses and fins separately, making it all but impossible to tell how many sharks have been processed on board and how many were subjected to shark finning. Meanwhile, the fin to carcass ratio (the means of checking that the number of fins corresponds to the number of carcasses – after sea processing – is within the ban’s limits) is the highest and therefore the most lenient in the world. Europe is home to the some of the world’s largest fishing fleets while its powerful fisheries officials exert influence on international fishing restrictions in many regions of the globe. Poor European shark policies, therefore, pose threats not only to shark populations in European waters but also to those around the world. If fisheries are managed carefully, sharks can provide a steady source of food and recreation and help keep the oceans in balance. The Shark Alliance is dedicated to ensuring that these valuable yet vulnerable animals survive and thrive for the benefit of ocean ecosystems and the people that depend on them.

The Shark Trust was established in 1997 to study, protect, and manage the elasmobranch species found in UK waters and internationally. It is a member of the European Elasmobranch Association and works with other EEA organizations to counter the enormous fishing pressure that European shark and ray stocks are under.
The Shark Trust’s mandate includes:
-
Introducing effective management on a regional basis to regulate shark and ray fisheries and ensure that they are sustainable.
-
Reducing shark and ray bycatch and mortality in other fisheries.
-
Increasing research efforts on the biology of sharks and rays and their fisheries, including the promotion of a collaborative tag and release program.
-
Improving records of catches, landings, and international trade in species of sharks and rays.
-
Improving management of critical habitats, including nursery grounds, under threat.
-
Increasing the amount of information available to the public and decision makers.
The Shark Trust encourages scientists, divers, fishermen, anglers, and the general public to join the growing number of ST members that currently lend their support.
Your membership in The Shark Trust adds to the pressure that it is able to be put on governing and regulatory agencies, and helps spread awareness on the plight of sharks and rays in general.
Subscription to The Shark Trust carries no obligation on your part unless you wish it to. However, if you would like to help educate or raise funds your added contribution will be most welcome.
Shark Trust members receive the trust’s magazine/newsletter ‘Shark Focus’ 3 times per year. This is a glossy publication that chronicles the latest work of the trust and has articles on a variety of shark and ray subjects. Upon joining the trust you will also receive i.d. posters of British shark and ray species and other Shark Trust goodies.
The Shark Trust also hosts a highly informative website with sections on all aspects of sharks and rays. The site also contains a good image database of elasmobranch species and an active and well moderated forum for anyone wishing to talk sharks.

he rapid decline of great sharks in the world’s oceans is disrupting the marine ecosystem by allowing more lowly fish to thrive, scientists warn today.
Overfishing of the ancient predators has lead to a sudden uprising of species they prey on, causing an abundance of skates, rays and smaller sharks, which are steadily devastating populations of shellfish, including scallops, oysters and clams, the researchers claim.
The findings suggest that the demise of the great sharks, whose primitive ancestors cruised the seas long before the rise and fall of the dinosaurs, may have unforeseen knock-on effects on marine life lower down the food chain.
Records from fisheries and research vessels dating from the 1970s to 2005 have revealed a dramatic nosedive in great shark populations. Tiger sharks and scalloped hammerheads may have declined more than 97% since the mid-1980s, while numbers of smooth hammerheads and bull sharks are believed to have fallen by 99% off the east coast of the US.
Writing in the journal Science, a team of marine biologists led by Ran Myers at Dalhousie University in Halifax, Nova Scotia, analyse fish research surveys over the past 16 to 35 years. The records show that while the abundance of 11 great shark species fell dramatically over the past 35 years, 12 of the 14 fish species they prey on had increased sharply.
In the waters along the US Atlantic coast, numbers of cownose rays, a staple of the great shark diet that can grow to four feet across, jumped 8% a year to an estimated population of around 40 million.
The explosion of the cownose population coincides with an almost complete collapse of scallops in the waters, leaving only those protected behind marine fences for local fisheries to take.
Without sharks to keep their numbers in check, researchers fear the migrating rays will drive down shellfish populations as they swim through, to the point where they are unable to recover .
Julia Baum, a co-author of the paper, said: “With fewer sharks around, the species they prey upon, like cownose rays, have increased in numbers, and in turn, hordes of cownose rays dining on scallops, have wiped the scallops out.”
Sharks are targeted by fisheries for their fins and meat, but are also taken as by-catch by fleets fishing for tuna and swordfish. As many as 73 million sharks are killed each year around the globe for the finning trade.
Ellen Pikitch, executive director of the Pew Institute for Ocean Science in Miami, said: “This is the first published field experiment to demonstrate that the loss of sharks is cascading through ocean ecosystems and inflicting collateral damage on food fisheries such as scallops. These unforeseen and devastating impacts underscore the need to take a more holistic, ecosystem-based approach to fisheries management.”
Charles Peterson, a researcher on the paper and marine biologist at the University of North Carolina in Chapel Hill, said the study highlighted the importance of maintaining populations of the ocean’s top predators. “Despite the vastness of the oceans, its organisms are interconnected, meaning that changes at one level have implications several steps removed. Through our work, the ocean is not so unfathomable, and we know better now why sharks matter,” he added.
In British waters, historic overfishing has seen the common ray decline to the point that surveys in the western channel have failed to spot any since the 1930s. More recently, numbers of blue and porbeagle sharks are believed to have fallen. The porbeagles are believed to be taken by Danish and French fleets, while Spanish long-line vessels take blue sharks migrating into British waters.
Last year, a team lead by David Sims of the Marine Biological Association in Plymouth tagged six blue sharks off the coast of Portugal to investigate their fate. Two were landed by fisheries within three months. “The ones that get here may be the survivors,” he said.
Dr Sims said the lack of hard data makes it extremely difficult to produce reliable assessments of fish populations, adding that many predators have such varied diets that cascade effects through ecosystems are complex and often difficult to pinpoint.
“There’s no doubt the fisheries are having an impact on the big shark populations, but what we really don’t know is what the ecosystem effects of that will be. There could be other factors involved that haven’t been measured,” he added.
