Note: I wrote the
following story in 1994 just before our National Geographic
Special “Jewels of the Caribbean” was aired. Since
then, shark diving in the Bahamas has become an extremely popular
sport bringing in much greater revenues than estimated in the
article below. Also since then, the decline of fish populations
around the world due to commercial fishing has accelerated enormously.
Many of the animals we filmed in the Cayman Islands were lost
to fishing (not driven away by divers). This includes the two
beautiful manta rays that used to come to anchored boats at
night at Little Cayman. The phenomenon whereby divers seem to
begin their career diving in a pristine environment only to
see major degradation in ten years is called “Shifting
Baseline Syndrome.” This is an important concept for all
lovers of wilderness. More can be learned about Shifting Baselines

Caribbean Reef Sharks ©Michele

The shark came from down-current
and followed the edge of the drop-off toward the smell of
bait. I waited next to a large purple tube sponge as Stuart
Cove shook the bait basket to increase the dispersion of chum.
I was surprised how quickly the first shark arrived. We hadn't
been down five minutes.
The shark was a six-foot long Caribbean
reef shark. It was a bit unusual because it had a circular
mark on its right side just posterior of the dorsal fin and
because it was worth $250,000. Ironically, no one owned this
animal. In fact, the only way to establish ownership of a
$250,000 shark is to catch it with hook and line or gill net
and kill it. But unfortunately, killing the shark causes its
value to depreciate. Dead, the shark is only worth fifty or
sixty bucks. The animal is worth $250,000 only when it's alive
and free.
Stuart shook the bait basket again and
I saw another shark rise over the edge of the drop-off. Another
$250,000 fish. Soon there were eight or ten large sharks swimming
around Stuart - several million dollars worth. The largest
might have been eight feet long and the smallest just over
five feet. By some calculation, the largest shark might have
been worth more than the smallest one. Perhaps the largest
was worth $300,000 and the small one only $200,000. Certainly,
it would be a difficult calculation to quantify the individual
value of each animal based on size or photogenics.
As the sharks gathered, the peanut gallery
took their places in a semi-circle behind Stuart. Bob Cranston
held the powerful HMI movie light, Mark Conlin held the light
cable, Doug Perrine and Michele Hall took still photographs,
and I operated the 16mm movie camera. We were not an entirely
typical sport diving group. However, this was a typical sport
dive for Stuart Cove's Resort. Typical, that is, until one
of the sharks bit Stuart.
I wasn't entirely surprised when Stuart
got bit. In fact, it seemed almost inevitable. Stuart was
reaching into the bait basket and tossing chunks of bait to
a gathering of sharks which were swarming around him like
an angry hoard of bees. Stuart casually fed the sharks in
much the same manner as an old man might feed a flock of pigeons
while sitting on a park bench. The big difference was that
pigeons are not inclined to remove and squabble over human
body parts.
Although I've had some experience diving
with sharks in several oceans of the world, my experience
with Caribbean reef sharks was very limited. Stuart, on the
other hand, had been putting on this show for years. It was
simple routine for Stuart. Still, I was impressed. Stuart's
position looked vulnerable and dangerous to me.
Perhaps one of the sharks sensed how
impressed I was. Perhaps the shark, somehow knowing I was
more experienced than the average tourist diver, felt a burst
of intense pride at my reaction. Perhaps the shark, inflated
with its sense of pride at being credited by a professional
diver for its fearsome reputation, and not wanting to disappoint,
decided to live up to my expectations. Or perhaps the shark
just thought Stuart's hand was a piece of fish. Whatever the
inspiration, the small $200,000 runt of a shark bit Stuart
on the hand.
Stuart's reaction was immediate and
predictable. He glanced at his hand, concealed it beneath
his arm, and shrugged as if to say, "It's only a scratch.
Nothing any self-respecting Bahamian shark diver would consider
significant." But then he noticed a gushing cloud of
green blood billowing from under his arm accompanied by a
moderate dose of pain, and reality set in. Stuart ascended
to the surface. The film crew immediately followed, perhaps
concerned about Stuart's condition or perhaps worried that,
hors d'oeuvrs having been served, the sharks may be in the
mood for the main course.
After a dozen or so stitches in his
hand, Stuart was good as new. I suggested he rub charcoal
into the wound to produce a respectable scar. But before he
fully realized the commercial value of this suggestion, his
hand had healed beyond the stage when rubbing in charcoal
could be done without significant increase in pain.
The following day our film crew was
back on site with divemaster, Billy Braithwaite, replacing
Stuart as guide. Soon Billy was feeding the pigeons just as
Stuart had. I continued to be impressed. The sharks, however,
seemed content to have once demonstrated a willingness to
be man-biters. No further demonstrations were necessary for
either the sharks or us. Or perhaps the offending shark had
warned its companions of the bad taste Stuart's hand had left
in its mouth. In any case, the following ten days proceeded
without further blood letting.
It's hard to say whether stories of
Stuart's shark bite increases or decreases the value of these
sharks. I suspect their value has gone up having validated
their nearly mythological reputation. A half dozen diving
resorts on New Providence attract sport divers to this small
Bahamian island largely on the strength of these wonderful
and spectacular shark dives. By Stuart's calculation, six
million dollars is spent in the Bahamas every year because
of these sharks. Six million dollars! And there are only a
dozen or so sharks.
The shark with the circular spot on
its side that I saw on my first dive was there every day we
dived the site. And when we returned to Nassau six months
later for additional filming, the same shark was still there
along with his dozen or so companions. If you divide 6 million
dollars by twelve sharks, you get a yearly value of $500,000.
Then, just to be conservative, if you arbitrarily divide that
estimate by two, you still get a yearly value of $250,000
per shark! However you do the math, these are very valuable
animals - as long as they're alive. A long-line fisherman
could catch them all in one night. Dead, each shark loses
99.8% of its value.
Stuart and the other resort operators
on New Providence are understandably concerned that one night
such a disaster might occur. As yet the Bahamian government,
along with most other governments around the world, has not
yet realized the relative commercial value of living marine
life versus dead marine life.
In the Cayman Islands, Sue Steere introduced
us to an entire community of valuable marine creatures. There
was an enormous eagle ray that allowed divers to approach
within feet, as it fed on mollusks concealed beneath the sand.
There was a manta ray that predictably came to feed on the
swarms of plankton that gathered under our movie lights. There
were schools of reef squid that allowed us to film them from
inches away. And there were Nassau groupers and tiger groupers
that would enter cleaning stations and allow us to film them
being cleaned at point blank range. These animals are part
of the reason that tens of thousands of tourist divers visit
the Caymans every year.
Nassau
Grouper ©Howard Hall |
There's a Nassau grouper that lives on the wreck
of the Oro Verde. He's the first thing divers see when they
hit the bottom near the wreck. And for many divers who go
to the Caymans, he's the biggest fish they have ever seen.
One morning Bob Cranston and I laid on the bottom near the
Oro Verde for three hours trying to film the spawning behavior
of yellowhead jawfish. (The jawfish, it turns out, had absolutely
no intention of performing sex for a movie camera). During
most of the dive, the Nassau grouper made a home for himself
right beneath my chest as I hunched over the movie camera
and looked through the lens at a jawfish who was not in the
mood. Occasionally, I gently pushed the grouper away concerned
that he might move suddenly, resulting in a cloud of dust
that would ruin any chance of filming the jawfish at a critical
moment. But within a few minutes, he'd be back and I'd again
find my chin resting on his forehead.
This silly fish may be even more valuable
than the sharks of New Providence. He enhances the Cayman
diving experience for thousands of divers each month. He's
been photographed tens of thousands of times and has appeared
in dozens of diving publication around the world. How could
you calculate the value of such an animal?
A few years ago a famous grouper lived
on the wreck of the Balboa in Georgetown Harbor. He was much
larger than the Nassau grouper that lives on the Oro Verde,
and because of his dramatic size, he was even more valuable.
During night dives this grouper would follow divers around
and occasionally snap up small reef fish that were exposed
by the divers' lights. His presence made the wreck of the
Balboa a world class dive. He was one of the reasons I planned
a film expedition to the Caymans.
For me, this grouper presented a unique
opportunity to film a predation sequence. Sue suggested that
all I had to do was set up my camera and lights, and the grouper
would perform on cue. Unfortunately, I never got the chance.
One night a commercial fishing boat tied up to the Balboa
mooring during a storm. While the fishermen waited for the
wind to abate, they put their lines over the side. Within
a few minutes most of the large and extremely valuable fish,
including the grouper, were gone.
The sport diving community and government
of the Cayman Islands have done a great deal to protect the
marine life and coral reefs surrounding their islands, setting
an example for the rest of the world. They've strategically
placed moorings around their islands to prevent anchor damage
to the reef. They've started the "no gloves" policy
to encourage divers to avoid touching the coral. And they
make every attempt to educate their customers about the impact
divers have on the environment. But while dive resorts around
the world are increasingly aware of the impact their customers
have on their natural resources, they still seem unaware of
the very much greater danger that lurks down the reef or just
over the horizon. Our oceans are being systematically strained
of life by commercial fishing. Ask any diver who has dived
any area for more than ten years. He will list the species
that were once seen in abundance and are now absent.
Divers tend to blame themselves for
the progressive disappearance of marine life, believing that
the increasing numbers of divers is driving the animals away.
But where do these animals go? Most often they go into the
fish holds of an aggressive fishing industry supplying a growing
population who value marine life only as food. The great majority
of this marine life is not driven away by divers. It only
appears that way because the marine life in an area seems
to decline as soon as divers begin exploring a site. But in
nearly all cases fish populations were already in dramatic
decline, only no one was there to witness it. Our marine life
is being swept from the ocean by the deadly technologies of
fishing. The sport diving community has initiated numerous
programs designed to reduced diver impact on the environment
while it largely ignores the far greater impact of commercial
fishing.
After three hours on the bottom watching
a pair of yellowhead jawfish doing absolutely nothing at all,
Bob and I gave up. I gently pushed the Nassau grouper aside
one last time and prepared to ascend. Sue and Michele passed
Bob and I as we ascended and when I looked back at the wreck,
I saw Michele taking photos of the grouper. She had already
exposed a half dozen rolls of film on the fish, but when the
fish swam up to her lens, she simply couldn't resist another
shot or two.
On our last evening in the Caymans we
celebrated the successful end of our filming expedition at
a beautiful Cayman Island diving resort. They had prepared
a spectacular buffet for the resort guests. A few minutes
after Michele left the table to be first in line at the buffet,
I followed. As I approached the buffet I found her standing
with an empty plate staring at the table. Featured at the
center the of the buffet was a twenty-five pound Nassau grouper,
exquisitely prepared and surrounded by colorful garnishes.
The fish probably cost the resort fifty bucks. But by another
calculation, it certainly cost much more.
