Many shark species are
endangered, and a number are on the verge of extinction. This is
primarily due to three major factors: destruction of habitats
(especially mangroves which serve as shark nurseries); by catch of ocean
going fish factories; and extreme exploitation and overfishing for their
fins and cartilage, all of which are used in useless and
superstitious ways by various cultures for food and "medicines". And the
endangered list includes not only lesser known sharks but also one of
the ocean's most magnificent predators, the Great White Shark as well as
the extraordinary Whale and Basking Sharks.
The shark populations of
the east coast of the United States have been reduced dramatically in
the past 15 years, including from 40 to 70% reductions in the
populations of tiger sharks, blue sharks and mako sharks. The
"International Action Plan For Sharks" initiated by CITES and the Food
and Agricultural Organization FAO report that more than 100 out of 400
shark species are being exploited commercially, and that many of these
species are so overexploited that their long term survival cannot be
guaranteed. More than 100 million sharks are caught annually. Not only
are sharks actively fished for their meat, fins or cartilage, but
millions of them die needlessly as undesirable byproducts brought in
from the nets and longlines of ocean going fishing factories.
Finning:
An especially brutal and cruel practice is finning, which is cutting off
of a shark's fins, often while the animal is still alive. The shark
trunk is then tossed overboard as useless waste. The epicenter of the
international shark fin market is Hong Kong and mainland China, where
the almost uncontrolled finning trade is a huge problem. It is estimated
that over 22,000 tons of shark fins are marketed worldwide, and most of
this ends up as "shark fin soup", a popular "status symbol" dish in many
oriental cultures. Unfortunately only a handful of countries have
introduced finning restrictions: Canada, Brazil, the United States,
Spain and Costa Rica and the attack on sharks for their fins continues
worldwide. Sharks are also exploited for their cartilage, which is
claimed falsely to have therapeutic uses in curing everything from
osteoarthritis to cancer.
Habitat destruction is
also another major threat to sharks. In order for young newborn sharks
to survive, they must have a place to hide from larger fish and other
sharks. For millions and millions of years, mangroves in shallow water
have served this purpose perfectly. However, coastal development in
recent years has accelerated considerably and the building of resorts,
golf courses and marinas where mangroves now threatens the very
existence of shark species. In the Philippines for example, the mangrove
forests have shrunk from 5,000 to only 300 square kilometers! This is a
catastrophic loss of nursery habitat for Philippine sharks.
