Feeding Frenzy: Why
is it still acceptable to eat
the endangered large
predators of the sea?

-------------------------------------------------------------
If these animals lived on
land there would be a
global outcry. But the
great beasts roaming the
savannahs of the open seas
summon no such
support. Big sharks, giant
tuna, marlin and
swordfish should have the
conservation status of
the giant panda or the
snow leopard. Yet still we
believe it is acceptable
for fishmongers to sell
them and celebrity chefs
to teach us how to cook
them.
A study in this week's
edition of Science reveals
the disastrous collapse of
the ocean's megafauna.
The great sharks are now
wobbling on the edge of
extinction. Since 1972 the
number of blacktip
sharks has fallen by 93%,
tiger sharks by 97% and
bull sharks, dusky sharks
and smooth hammerheads
by 99%(1). Just about
every population of major
predators is now in
freefall. Another paper,
published in Nature four
years ago, shows that
over 90% of large
predatory fishes throughout the
global oceans have
gone(2).
You respond with horror
when you hear of Chinese
feasts of bear paws and
tiger meat. But these are
no different, as far as
conservation is
concerned, from eating
shark's fin soup or
swordfish or steaks from
rare species of tuna.
One practice is considered
barbaric in Europe and
North America. The other
is promoted in
restaurant reviews and
recipes in the colour
supplements of respectable
newspapers.
In terms of its impact on
both ecology and animal
welfare, shark fishing
could be the planet's most
brutal industry. While
some sharks are taken
whole, around 70 million
are caught every year
for their fins(3). In many
cases the fins are cut
off and the shark is
dumped, alive, back into the
sea. It can take several
weeks to die. The
longlines and gillnets
used to catch them snare
whales, dolphins, turtles
and albatrosses. The
new paper shows that shark
catching also causes a
cascade of disasters
through the foodchain. Since
the large sharks were
removed from coastal waters
in the western Atlantic,
the rays they preyed on
have multiplied tenfold
and have wiped out all
the main commercial
species of shellfish(4).
Much of this trade
originates in East Asia, where
shark's fin soup - which
sells for up to £100 a
bowl - is a sign of great
wealth and rank, like
caviar in Europe. The
global demand for shark
fins is rising by about 5%
a year(5). But if you
believe that this is yet
another problem for
which the Chinese can be
blamed and the Europeans
absolved, consider this:
the world's major
importer (and presumably
re-exporter) of sharks
is Spain(6). Its catches
have increased nine-fold
since the 1990s(7) and it
has resisted - in most
cases successfully - every
European and global
effort to conserve its
prey.
The Spanish defend their
right to kill rare
sharks as fiercely as the
Japanese defend their
right to kill rare whales.
The fishing industry,
traditionally dominated by
Galician fascists,
exerts an extraordinary
degree of leverage over
the socialist government.
The Spanish government,
in turn, usually gets its
way in Europe. The EU,
for example, claims to
have banned the finning of
sharks. But the ratio it
sets for the weight of
fins to the weight of
bodies landed by fishermen
is 5%. As edible fins make
up only 2% of the
shark's bodyweight(8),
this means that two and
half finless sharks can be
returned to the water
for every one that comes
ashore. Even this is not
enough for the Spanish,
whose MEPs have been
demanding that the
percentage is raised(9).
Northern European
civilisation doesn't come out
of this very well either.
In 2001 the British
government promised to
protect a critically
endangered species called
the angel shark, whose
population in British
waters was collapsing. It
ducked and dithered until
there was no longer a
problem: the shark is now
extinct in the North
Sea(10).
Why do we find it so hard
to stand up to
fishermen? This tiny
industrial lobby seems to
have governments in the
palm of its hand. Every
year, the European Union
sets catch limits for
all species way above the
levels its scientists
recommend. Governments
know that they are
allowing the fishing
industry to destroy itself
and to destroy the
ecosystem on which it depends.
But nothing is sacred, as
long as it is
underwater. In November
the United Nations failed
even to produce a
resolution urging a halt to
trawling on the sea mounts
at the bottom of the
ocean. These ecosystems,
which are only just
beginning to be explored,
harbour great forests
of deepwater corals and
sponges, in which
thousands of unearthly
species hide. But we can't
summon the will to stop
the handful of boats that
are ripping them to
shreds.
The power of the
fishermen's lobby explains the
lack of protection for
marine predators. Though
fish species far outnumber
mammal species, the
Convention on
International Trade in Endangered
Species protects 654 kinds
of mammal and just 77
kinds of fish. Trade in
only 9 of these is
subject to a complete
ban(11).
The rules that do get
passed are ignored by both
fishermen and governments.
On Sunday I stood with
a fisheries manager on the
banks of a famous sea
trout river in Wales.
Perhaps I should say a
famous former sea trout
river in Wales. For the
past four years, scarcely
any fish - sea trout or
salmon - have appeared. He
was not sure why, but
he told me that trawlers
in the Irish Sea land
boxes of what appear to be
bass; hidden under the
top layer are salmon and
sea trout. No one seems
to care enough to stop
them: government
monitoring appears to be
non-existent. The
pressure group Oceana
walks into European ports
whenever there's a public
holiday and finds
hundreds of miles of
illegal drift nets stowed on
the boats(12,13,14). Where
are the official
inspectors?
Of course, governments
plead poverty. Which makes
you wonder why they
decided last year to allocate
?3.8 billion to the
destruction of the marine
environment. This is what
you and I are now
paying in subsidies to
keep the ocean wreckers
afloat. The money buys new
engines, and boats for
young fishermen hoping to
expand their
business(15). For the same
cost you could put a
permanent inspector on
every large fishing vessel
in European
waters.
If we don't act, we know
what will happen.
Another paper published in
Science suggests that
on current trends we'll
see the global collapse
of all the species
currently caught by commercial
fishermen by 2048. Yet, if
we catch the
ecosystems in time - with
temporary fishing bans
and the creation of large
marine reserves - they
can recover with
remarkable speed(16). I hope
British ministers, now
drafting a new marine
bill, have read this
study.
But beyond a certain point
the collapse is likely
to be permanent. Off the
coast of Namibia, where
the fishery has crashed as
a result of
over-harvesting, we have a
glimpse of the future.
A paper in Current Biology
reports that the
ecosystem is approaching a
"trophic
dead-end"(17). As the fish
have been mopped up
they have been replaced by
jellyfish, which now
outweigh them by three to
one. The jellyfish eat
the eggs and larvae of the
fish, so the switch is
probably irreversible. We
have entered, the paper
tells us, the "era of
jellyfish ascendancy".
It's a good symbol. The
jellyfish represents the
collapse of the ecosystem
and the spinelessness
of the people charged with
protecting it.
