These
remarkable creatures, fish really, live in coastal and estuarine
habitats the world over. Seahorses, sea dragons and pipefish have
adaptations that are unlike those of any other fish: tube like mouths,
exquisite grasping tails, rigid bodies, rotating eyes that move
independently and the ability to change color to match the
surrounding plants. Human development has destroyed a large
portion of their natural habitats around the world, and fisheries
harvest, based primarily on folk medicinal uses and souvenir production
(the dried carcasses are sold as souvenirs..) results in a kill of 200,000,000
seahorses each year!
"It is estimated that there
are currently 32 species of seahorses around the world, ranging in size
from 1-30 cm. The majority of seahorses are found in the shallow waters
of the West Atlantic or the Indo-Pacific regions while two species can
be found off the south coast of Britain. Seahorses belong to the family
Syngnathidae, along with pipefishes, pipehorses and seadragons, all of
which are thought to have evolved at least forty million years ago.
Seahorses are unusual in that it is the male who becomes pregnant,
carrying the developing young in his brood pouch.
Many seahorse species were added
to the World Conservation Union's Red List of Threatened Animals in
1996. Both heavy exploitation and habitat degradation are contributing
to declines of up to 15-70% in many seahorse populations over periods of
5-10 years. At least twenty million seahorses are traded each year - the
majority used as traditional medicines. The aquarium trade also deals in
live seahorses, despite the fact that they are difficult to keep in an
aquarium. In this way, a vicious circle is created: aquarium owners
often replace the dead ones, thereby contributing to their continuing
decline. Seahorses are also traded as tacky souvenirs, incorporated in
shell craft, yo-yos and other curios.
Seahorses are found in nearshore
habitats that are among the most threatened in the world. Degradation
and destruction of these coastal ecosystems due to mangrove cutting,
coral mining, dynamite fishing, trawling, land-derived pollution and a
host of other human activities negatively affect these threatened
species."
FACT: Twenty
millions seahorses are taken from the wild each year for use in
Traditional Chinese Medicine. The World Health Organization
recognizes that this approach to medicine has been used for
centuries; however many scientists now doubt that the wild
populations can sustain current harvests. The tragic element in this
equation, from the standpoint of western empirical science, is that
an unsubstantiated claim, perhaps just a superstition -"beneficial
powers from seahorses" - is driving these animals towards the point
of extinction in this region. The solution is clear -immediate
education regarding harvesting of seahorses (as in the WHO Project
Seahorse), followed by real scientific study to determine once and
for all if there really is something to the claim, and if not, then
cultural change in the light of the scientific facts. The burden for
this, in my eyes, lies with the modern Chinese scientific community.
FACT: Closer
to home, research has shown that nearly 90% -Yes 90%!! of the
natural sea grass beds in the Chesapeake Bay have disappeared over
the past 50-100 years. Seahorses and pipefish have small home
ranges, so the loss of these beds has a devastating effect. The
exact number of population decline of seahorses in the Bay is not
known, but the general scientific conclusion is that they have taken
a major hit. Currently, conservation groups, scientists and
volunteers are re-planting sea grass beds along the Chesapeake Bay
and Atlantic coastal areas. It is hoped that this massive effort
will prevent the inevitable extinction of these lovely creatures
that is certain to come without this intervention.
