Talk
Show
with
some fun
and
interesting
stories
about
fish in
the
news.
A Viperfish,
with a fearsome grin fit for a movie monster, is a real-life predator that lurks in one of the world's most remote locations.
Sandbar Shark wrestles with biologists recently on a beach in Spain.
This 16" Pacu
was caught by a fisherman in Lake St. Clair, Michigan, last week.
Sarah Anderson,
a high school teacher, will leave on an expedition to the Amundsen Sea in a part of Antarctica that hasn't been visited in more than a century.
Quagga Mussels
have quickly spread to Southern California.
In Tokyo, Japan,
A Spa, Where
the Fish Food
is You.
In May 2006,
the Ooedo-Onsen-Monogatari
(www.ooedo-global.jp),
a 4-year-old
hot-springs
spa in the city's
Odaiba area,
added a new
treatment to
its menu: Doctor
Fish's "pedicure"
and "manicure."
In a reversal
of the food
chain, the fish
dine on you
- or at least
parts of you.
In a culture
where food and
fashion seem
straight out
of science fiction,
Doctor Fish
is hardly extraordinary.
Strangely enough,
the spa's finned
employees, which
are imported
from Turkey
and are known
scientifically
as Garra rufa,
have a taste
for dry, flaking
human skin.
The fish act
like living
pumice stones,
nibbling off
the dead epidermis
and leaving
behind baby-smooth
skin. Click

From National
Geographic Magazine,
Weird Deep-Sea
Creatures Found
in Atlantic.
With a fearsome
grin fit for
a movie monster,
this viperfish
is a real-life
predator that
lurks in one
of the world's
most remote
locations. An
international
team of 31 researchers
found this and
other strange
animals while
exploring the
Mid-Atlantic
Ridge, an underwater
mountain range
that runs from
Iceland to the
Azores islands
west of Portugal.
Over the course
of five weeks,
the team cataloged
a host of exotic
worms, colorful
corals, unusual
sea cucumbers,
and weird fish.
Clearly, viperfish
has plenty to
eat. Many of
the species
found on the
ridge are rare
and had only
been discovered
in recent years,
scientists said.
At least one
species found
during the survey
- a
tiny crustacean
called a seed
shrimp - is thought
to be new to
science.

In the North
Atlantic Ocean,
Scientists
ask: Where have
all the Dolphins
gone?
Sightings
by marine
scientists
of dolphins
in the north
Atlantic's
Bay of Biscay
have dropped
off by 80
percent
compared
to the same
period in
2006, a
wildlife
conservation
group said
Wednesday.
The alarming
drop in
numbers
of the Bay's
three most
common species
of dolphin
-- the striped,
bottlenose
and common
-- can be
attributed
to one or
both of
two causes,
Clive Martin,
senior wildlife
officer
for the
Biscay Dolphin
Research
Programme.
"We know
for a fact
that by-catch
is killing
thousands
of dolphins
every year,"
he said,
referring
to commercial
fishing
operations
in the bay,
which is
formed by
the northern
coast of
Spain and
the eastern
French seaboard
up to the
tip of Brittany.
Martin singled
out French
"pair trawlers"
that sweep
the ocean
with huge
nets twice
the size
of a football
pitch strung
out between
them as
being especially
lethal to
the marine
mammals.
"Dolphins
are sometimes
trapped
hundreds
at a time,
and are
asphyxiated"
when they
cannot come
up for air,
he said.
Most dolphins
typically
replenish
their lungs
with fresh
air every
five minutes
or so, he
explained.
The second
-- and probably
more important
-- reason
that dolphins
have disappeared
is that
there is
simply very
little left
for them
to eat.
"Anchovy
fishing
in the Bay
of Biscay
has progressively
failed,
and this
year there
is a complete
ban by Spain,
France and
the United
Kingdom
on the fishing
of anchovies,"
a principal
food source
for dolphins,
Clive said.

On a Beach
in Spain,
Biologists
nab the
Shark that
became a
Celebrity.
Biologists
caught a
two-metre-long
(7-foot-long)
shark that
had become a
tourist
attraction
by making
daily
incursions
into
knee-high
water on a
Spanish
beach,
wrestling it
with their
bare hands
and dragging
it ashore.
The
50-kilogram
(110-pound)
sandbar
shark - not
generally
associated
with attacks
on humans -
first showed
up early
last week at
a beach
called
Miracle in
northeast
Tarragona
province,
forcing
authorities
to close off
the water to
bathers. The
fish turned
into a
novelty by
swimming
regularly
into plain
view in very
shallow
water.
Bathers
gathered
daily to
snap photos.
Police fined
several
people who
ventured
into the
water to
splash
around with
it. A team
of three
biologists
from the
Barcelona
Aquarium
waded in
yesterday
and, after
two failed
attempts
before a
crowd of
hundreds,
finally
managed to
capture the
flailing
shark with
their hands.
They quickly
stuck its
snout into a
net to keep
it from
biting. Two
of the
rescuers
were
slightly
injured with
cuts and
scratches
from the
shark's
fins. The
team put the
fish into a
tank and
trucked it
for a
police-escorted
ride to the
aquarium and
a medical
checkup. "It
will be in
quarantine,
just as
would be
done with a
sick
person,"
aquarium
director
Jordi Ingles
said
yesterday.
He said the
shark will
be returned
to the open
sea if
biologists
determine it
is healthy. Click

From
Lake St.
Clair in Michigan,
A Fish
Story --
with Teeth
This was no
ordinary
fish. The
tug on the
line was too
vicious, too
unyielding.
When the
silvery
beast
emerged from
Lake St.
Clair with
its teeth
baring last
week, angler
Toby Davison
knew he
caught
something
special.
Turns out,
the
43-year-old
angler from
St. Clair
Shores
snagged a
Pacu, a
close cousin
of the
piranha.
Both mainly
prowl in
South
America.
Davison said
he plans to
mount his
catch.
Luckily for
swimmers and
boaters at
popular Lake
St. Clair,
Pacus, which
can grow up
to 3 feet in
length,
aren't known
for
attacking
humans. And
they likely
wouldn't
survive a
Michigan
winter. But
fisheries
officials
say
Davison's
catch
illustrates
a
troublesome
trend of
people
dumping
their exotic
pets. "It's
against the
law and can
damage the
ecology,"
said Mike
Thomas,
fisheries
research
biologist
for the
Michigan
Department
of Natural
Resources in
Harrison
Township. Located
between
lakes Huron
and Erie,
Lake St.
Clair is the
smallest
lake in the
Great Lakes
system.
Heart-shaped
and shallow
(averaging
only 10
feet/3
meters
deep), the
lake
requires
periodic
dredging to
ensure
bottom
clearance
for large
ships. The
northeastern
portion of
Lake St.
Clair is an
extensive
delta
system, the
largest
within the
Great Lakes.

In Lake
Malawi, East
Africa,
Evolution
by Parasite
An old
puzzle
relating to
the East
African
cichlid fish
species may
have been
solved. For
decades,
evolutionary
biologists
have been
puzzled as
to why the
fish do not
interbreed,
despite
living side
by side and
being
comprised of
hundreds of
closely
related
species.
Now, a team
from Canada
(Université
Laval), the
UK
(University
of Hull,
Cardiff
University)
and Spain (Donana
Biological
Station),
have studied
two of the
species
(Pseudotropheus
emmiltos and
Pseudotropheus
fainzilberi)
which are
found in the
north
western part
of Lake
Malawi.
Previously,
the only
known difference
was the
colour of
the dorsal
fin. Now,
research
into mate
selections
has
demonstrated
that the
fish
recognise
'their kind'
through
olfactory
communication
(smell)
rather than
aesthetics.
In addition
to this, the
findings
demonstrate
that
parasites
found on the
two species
were
significantly
different.
As some of
the genes
known to
influence
mating
behaviour
through
olfaction
are
sensitive to
molecules
produced by
infectious
agents they
can smell
how
effective
their
potential
offspring’s
immune
systems
would be to
certain
infections.
"The precise
role that
this
divergence
played in
the
evolution of
reproductive
isolation
has yet to
be studied,"
commented
Louis
Bernatchez,
co-author of
the study…”,
but it
offers an
exciting new
perspective
in the study
of African
cichlids
speciation." Click

From
the Telegraph.co.uk,
Young
Sprouts:
Gardening
for
Children.
Even if you
only have a
small
outdoor
space you
and your
child can
easily
create a
mini
wildlife
pond with a
selection of
marginal and
submerged
plants.
Tubtrugs
make great
container
water
gardens that
are
waterproof,
extremely
sturdy, and
stand up
well to
ultraviolet
light and
frost. As
well as
work-a-day
plain black
containers
made from
100%
recycled
plastic,
Tubtrugs are
available in
15 striking
colours.
Raised off
the ground
and
generously
filled with
cobbles or
paddle
stones, they
are safer
for children
than a
larger pond
sunk in the
ground. A
container
water garden
this size
could
include one
or two
native
marginal
plants, such
as a soft
rush (Juncus
effusus), a
single-flowered
white marsh
marigold (Caltha
palustris
var. alba)
or water
mint (Mentha
aquatica),
an
oxygenator
and a
submerged
plant, such
as a pygmy
water lily
(Nymphaea
pygamea 'Rubra'). Click

In San
Diego,
California,
Invasive
Mussel
Species
confirmed as
harmful.
Escondido
officials
yesterday
confirmed
that mussels
found at
Dixon Lake
earlier this
week are a
prolific
non-native
species
capable of
harming
freshwater
ecosystems
and clogging
pipes and
pumps.
A larval
form of the
same species
of mollusk,
known as
Quagga
mussels,
also was
discovered
this week in
San Vicente
Reservoir
near
Lakeside,
where
drinking
water is
stored for
the city of
San Diego. In January, Quagga
mussels were
found in
Lake Mead,
which
straddles
Nevada and
Arizona.
However,
officials
were caught
off-guard by
their quick
spread to
Southern
California. Click
