Predator Is Prey: Sharks Killed for Fins
|
Shark science 2000-2007

There are very few places on the planet where great white sharks can be
studied with relative ease by scientists and also be observed and
appreciated by the public. The seasonal population of 140 sharks at Isla
Guadalupe is generally recognized as the best place in the world to see
and study these magnificent animals. Although white sharks are a
protected species, they are still caught and sold commercially. The
value of one white shark carcass on the black market can reach over
$20,000, an amount that provides an enormous incentive for illegal
fishing. Our goal is to assist the Government of Mexico as much as
possible to help protect this rare and unique population of sharks. With
the daily catch of sharks worldwide estimated at 273,000 animals, the
threat to this remote and unique population is real and ominous.
In 2005 one shark was deliberately hooked by private sport fishers right
in front of a group of astonished divers. Fortunately, a local film crew
was on board one of the dive boats who raced over and managed to scare
off the sport fishermen. Though this shark got lucky, there are others
that don’t because resources are needed to protect the waters around
Isla Guadalupe.
In addition to helping protect Isla Guadalupe from illegal shark
fishing, the Guadalupe Island Conservation Fund also provides support to
the ongoing CICIMAR-U.C Davis
shark research tagging program. Recent tagging data is revealing a
previously unknown predator/prey relationship between white sharks and
the endemic Guadalupe fur seal population. Since predation by white
sharks occur underwater this relationship was unknown until recently.
Research such as this will not only help us learn more about white
sharks, it will also help protect them.

Grupo Ecología y Conservación de Islas, A.C. and CONANP, the Mexican
National Park Service, are collaborating on terrestrial and marine
conservation projects to protect the resident great white shark
population, as well as the sea birds, marine mammals, and endemic plant
species that make Guadalupe Island such a special place.
