Saving Jaws
Over 100, 000, 000 sharks are slaughtered annually, at a rate of over
270, 000 per day. Sharks are being targeted for sport,
caught for their fins and jaws,
killed in anti-shark nets, as by-catch,
their habitat is being degraded as well as polluted,
and humans continue to over-exploit their food sources. Shark
populations are particularly vulnerable to this exploitation due
to inherent life history characteristics which feature a pattern
of slow growth, late maturity, long gestation, low fecundity (reproductive
output) and long life, resulting in a slow intrinsic rate of population
increase. As a result, shark populations worldwide are drastically
declining. In the Atlantic alone, shark populations have decreased
between 60 and 90 percent depending on species, in just the last
15 years! Sharks have inhabited our oceans for over 400 million years
and in just two decades of human over-exploitation, are now threatened.
The long term effects of shark declines from their communities is unknown,
but likely far reaching as sharks are ecologically important components
in virtually every marine habitat.
In
the immediate years following the 1975 epic release of JAWS the
general public felt that 'every good shark was a dead shark,' however
in the thirty years that have followed, this mentality has changed.
People are starting to realize the importance of sharks in the marine
ecosystem. Moreover, many people now regard the oceans as more beautiful
for including such awesome animals. Increasing numbers of people
are coming to appreciate that sharks add to the diversity, mystery
and excitement of our oceans.
Ultimately, to save Jaws, international commercial shark
fishing will need to come under shared international regulations
adopted by all countries fishing as well as finning and by-catch
will need to stop. With
this being said, you can help shark conservation efforts by boycotting
the sale of shark parts and products, by encouraging others to do
the same and by supporting shark education and research. Every person
can make a difference and with your efforts, sharks will survive
to play their ecological roles in the oceans as well as continue
to amaze and inspire.
Sources of Shark Mortality:
-
Sport
The
ocean is the planet's true last remaining wild place. Unlike
the Congo or Serengeti, there are no eventual fences surrounding
the oceans and its creatures. Unlike lions in a circus, humans
have no control of sharks; they remain one of nature's remaining
truly wild creatures. This has led macho primate warriors to
the ocean to hunt and kill sharks in an awesome display of
power and all in the name of sport.
Thousands
of coastal sharks are killed annually for recreational sport.
Most shark meat isn't too valuable as a food source because
their tissues contain high levels of urea (see research section under
osmoregulation), making them inedible. Thus if the animal isn't
released, it is usually mounted on a wall. As shark species
continue to decline, a large number of recreational anglers have
fortunately adopted sustainable catch and release shark fishing
See NewEnglandSharks.com for an excellent example of sustainable catch and release recreational shark fishing. Save-Our-Sharks.org

For
Their Fins:
Shark
fin soup is a delicacy in some Asian cultures. The soup
can fetch up to several hundred U.S. dollars per bowl. Some
fins can fetch thousands of dollars depending on the rarity of
the shark species as well as fin age and type. The soup itself
is colorless and odorless and the fin just adds thickening to
the broth. Serving
shark fin soup is a sign of wealth, like caviar, and a tradition
in many Asian weddings. But what is the cost of this sign
of wealth and tradition Millions of sharks slaughtered
annually!
Shark
fins are harvested from the animals in a process
called finning. The practice is wasteful, unsustainable
and ecologically unsound. In the process of finning, sharks are caught on long-lines (literally, miles of line floating in the oceans affixed with hooks and bait), brought to the boat, their fins are hacked off, and the mutilated, but live animals are then thrown back in to the water where they die. The shark carcasses are discarded to make space on the boat for more fins since shark meat is not as profitable as fins.
Recent Ban on Shark Finning:
In a series
of actions over 1993-2002 the United States banned shark finning
by U.S. fishing boats. In 2004, the International Commission
for the Conservation of Atlantic Tunas banned shark finning in
the Atlantic Ocean, Gulf of Mexico and Mediterranean Sea. In
2005 the Inter-American Tropical Tuna Commission (IATTC) adopted
by consensus a Resolution on Sharks that includes binding measures
to ban shark finning (using a 5% fin to carcass ratio), improve
shark catch data collection and establish a shark status advice & assessment
process for IATTC- managed fisheries in the Pacific Ocean. As
with that agreement, the IATTC Resolution also encourages live
release of unwanted sharks, efforts to improve gear selectivity
and research into shark nursery areas. In addition,
the IATTC Resolution calls on countries to implement national plans
of action for sharks, in accordance with the FAO International
Plan of Action for the Conservation and Management of Sharks.
These steps are extremely important for the conservation of shark
species; however illegal shark finning is still taking place
and greater enforcement and larger fines are needed. In
addition, due the trans-ocean movements of many pelagic shark
species as well as the connectivity of the oceans, international
shark finning regulations will need to be adopted by all fishing
countries in all the world's oceans to conserve and regulate
worldwide shark stocks.

For Their Jaws
(Click right-hand side image to enlarge)
There is no doubt that a set of shark jaws is impressive,
the bigger the better! However, many sharks are being caught to
supply a shark jaw trade. Some jaws can sell for thousands of
dollars, depending on its condition and from which species it was
taken. A quick
search on eBay will reveal the magnitude of the shark jaw market.
The white shark was listed on CITES (Convention on International
Trade in Endangered Species of Wild Fauna and Flora) Appendix II
in October of 2004, forbidding the international trade of their
jaws and fins. Seven
months following, a white shark jaw was listed on eBay for a
starting bid of $30, 000.000 Australian Dollars (approx. USD $23,
000.000).

-
Killed in Anti-Shark Nets
Various beaches in Australia and South Africa are protected
by anti-shark nets. The nets do not form an impenetrable barrier
separating the sharks from bathers; but are just meant to passively
kill sharks, thereby effectively lowering their populations and
thus shark attacks. The
nets have successfully done so and shark populations in netted
areas continue to decline yearly. Interestingly, the Natal
Sharks Board, who maintain the anti-shark nets along the South
African Kwa-Zulu Natal coastline, report that 90 % of the sharks
that are caught, are on the inside of the nets. This reveals
that before being caught, the sharks had been swimming amongst
bathers only to be caught on their way back out to sea.
Note: The Natal Sharks Board has a very productive shark research program and is involved with conservation efforts.

-
As By-Catch
By-catch refers to unintentional catch. Many sharks are
unintentionally caught on commercial fishing long-lines targeting
tuna and/or swordfish. Long-lining
is the most common form of commercial fishing for tuna and swordfish
in the Atlantic, Pacific and Indian Oceans. It involves a single
fishing line that can extend up to 60 miles (100 kilometers), which
dangles thousands of baited hooks waiting for a fish to bite. However,
this type of fishing gear is indiscriminate and the hooks kill anything
that bites, like turtles, birds, seals, dolphins and sharks. 1.4
billion long-line hooks are set a year and the unintentional catch
of sharks (by-catch) is the largest threat to their populations globally. For
example, between 1997 and 1998, 450, 000 blue sharks alone were taken
by the tuna long-line fishery in New Zealand.

-
Habitat Degradation
More
than half of the world's population lives within approximately
100 km of the ocean and as such, coastal areas are being degraded
at an alarming rate affecting the species that rely on these
areas for their survival. Many sharks utilize inshore lagoons
or mangroves in tropical areas as nursery grounds. Pregnant
females come to these sites to give birth and juvenile sharks find
protection in these sheltered areas. As coastal development
increases, more of these areas are being degraded. The best
spot for most tropical hotels are these sheltered lagoon or mangrove
areas vital to successful shark recruitment and survival. Inevitably
the hotel is built and the shark nursery grounds are destroyed.
For example, in Bimini, Bahamas, construction has begun on the
first phase of a mega-resort, including condominiums, a casino,
and golf course. If allowed to proceed, the complex will consume
the mangroves of the North Sound and East Bimini, together with
all of the animals and plants that live there. The location where
construction is planned is a particularly important nursery ground
for lemon sharks.
To help support conservation efforts in Bimini purchase "Shark of Bimini" T-shirts, posters and/or postcards at Global Response.

-
Polluted
The ocean is the land's garbage can. Eventually everything
ends up in the oceans. Metals and slowly degrading chemicals
threaten inland and coastal waters. Toxic materials settle
into sea-floor sediments where they accumulate as hazards to organisms
that live in and feed on bottom muds. Eventually, long-lasting
chemicals enter the food web and bio-accumulate up the
food chain to its apex predators, the sharks. Pregnant woman are discouraged
from eating shark meat, because their tissues contain extremely
high levels of methyl mercury. The Shark Research Institute
recently reported that tissue samples taken from a whale shark from
Mozambique waters revealed that their tissues contain lead levels in
excess of 100 parts per million (for reference, beef with lead levels
of 10 parts per million is considered unfit for human consumption).
Such toxins may have adverse affects on shark health, reproductive
output and the survival of their offspring.

-
Over Exploit their Food Sources
 Fish such as tunas, sharks, cod and billfish have declined in
the oceans by over 90 % in just the last 50 years due to human over-fishing.
So not only are sharks directly being fished, but so are their
food sources. Although shark senses are unbelievably apt
at locating prey, they cannot compete with echo-locators, fish
finders and the 3.8 million long-line hooks that are set daily
which continue to wipe out global fish stocks.

What YOU Can Do To Save Jaws
You
can help shark conservation efforts by boycotting the sale of shark
parts and products, by encouraging others to do the same and by supporting
shark education and research. Every person can make a difference.
The combined efforts of people have resulted in shark fin soup being
removed from restaurant menus, major credit card promotions and even
airline menus. Through petitions and letter writing campaigns governments
have put regulations in place to protect sharks, shark kill fishing
tournaments have been cancelled and aquariums have stopped exhibiting
endangered shark species.

People Have the Power: A Shark Success Story
In May 2005, Disney announced that shark fin soup will be
available for business dinners, special events, and weddings at
Hong Kong Disneyland, opening September 2005. Many organizations
formally requested that Disney remove shark fins from their menus,
but Disney refused:
"Hong Kong Disneyland takes environmental stewardship
very seriously but we are equally sensitive to the local cultures.
It is customary for Chinese restaurants and 5-star hotels to
serve shark fin soup in Hong Kong as the dish is considered as
an integral part of Chinese banquets." (Esther Wong, Public
Relations Manager. Quote also attributed to Irene Chan.)
As the general public became aware of the issue, public
email and letter writing campaigns were initiated independently
through dive clubs, elementary schools, universities and conservation
organizations. After a month of constant bombardment Disney executives
finally backed down on June 24, 2005, agreeing to remove shark
fin soup from its menus. The "official" reason given
that Disney could not find a "sustainable" source for
shark fins - however, Disney executives clearly felt the pressure
from the thousands of emails, letters, and phone calls it was receiving
as well as the escalating calls for a boycott from the general
public.
