Fish in
the
News.
Each
week the
Bailey
Brothers
start
the Pet
Fish
Talk
Show
with
some fun
and
interesting
stories
about
fish in
the
news.
Anyone for
Fishy Ice Cream?
Doesn't sound
yummy? How about
using a fish
protein to make
better low fat
ice cream? The
deep sea ocean
pout has an
anti-freeze
protein in its
blood that protects
the fish against
tissue damage
from ice crystals.
That's a useful
adaptation to
life in the
sub-freezing
temperatures
of the deep
North Atlantic
ocean. In ice
cream, the fish
anti-freeze
protein replaces
fat by lowering
the temperature
for ice crystal
formation. So
far, so good,
but it would
take squeezing
too many fish
to extract the
protein from
real fish, so
Unilever wants
to use genetically
modified yeast
to produce the
fish protein
in vats. Opponents
of food produced
from genetically
modified organisms
probably don't
want to see
this happen.
Will we see
blockades of
ice cream factories?
Who knew deep
sea fish had
such potential
for commercial
success and
tasty technology?

From the University
of California
at Berkeley
Discovered:
Octopuses Flirt
and Hold "Hands"?
For decades,
scientists have
viewed octopuses
as unromantic
loners, with
mating habits
nearly devoid
of complex behavior.
But new research
from the University
of California,
Berkeley, has
found that at
least one species
of octopus engages
in such sophisticated
lovemaking tactics
as flirting,
passionate handholding
and keeping
rivals at arms'
length. "This
is not a unique
species of octopus,
which suggests
others behave
this way," said
Roy Caldwell,
a professor
of integrative
biology at UC
Berkeley and
co-author of
the study. In
the wild, researchers
observed macho
octopuses that
didn't just
mate with the
first female
that crossed
their path.
Many picked
out a specific
sex partner
and jealously
guarded her
den for several
days, warding
off rivals to
the point of
strangling them
if they got
too close. When
flirting or
fighting, they
would signal
their manliness
by displaying
striped body
patterns. Click

At the University
of Washington
Robofish
form Teams of
Underwater Robots.
Many of today’s
underwater robots
need to periodically
come up to the
surface to communicate
with their human
supervisors.
But researchers
at the University
of Washington
(UW) have developed
a new kind of
underwater vehicle.
The Robofish
can work cooperatively
with each other.
‘The Robofish,
which are roughly
the size of
a 10-pound salmon,
look a bit like
fish because
they use fins
rather than
propellers.’
According to
the researchers,
such robots
‘could cooperatively
track moving
targets underwater,
such as groups
of whales or
spreading plumes
of pollution,
or explore caves,
underneath ice-covered
waters, or in
dangerous environments
where surfacing
might not be
possible.’ Click

Among the Coral
Reefs in Hawaii
"Super Suckers"
Slurp Invasive
Algae Off Reefs
An invasive
algae, called
gorilla ogo,
has slowly overtaken
Hawaii's reefs,
making the situation
dire, experts
say. The Super
Sucker, a new
type of underwater
vacuum, has
been successful
in removing
harmful algae,
which is shown
above in the
lower picture,
and restoring
reefs to their
natural, healthy
state, as show
above in the
upper picture.

A Strange
Crustacean Transformation
The mysterious
Y-larva has
a strange way
of growing up.
The speck-sized
crustacean,
found throughout
the world's
oceans, has
only been observed
in its larval
form--until
now. Researchers
have discovered
the next step
in this animal's
life, and the
transformation
is extreme--the
many-legged,
flealike larva
turns into an
eyeless, brainless
blob. This unusual
devolution from
sophisticated
to simple provides
clues to how
the final adult
form of the
animal, which
still remains
unobserved,
makes a living.

University
of
California,
San Diego,
Renowned
Physicist
and Inventor
of Wetsuit
Dies.
Hugh Bradner
built a
successful
career by
combining
his passion
for science
and ocean
exploration.
Hugh Bradner,
renowned
physicist
and
professor
emeritus at
Scripps
Institution
of
Oceanography
at UC San
Diego, died
May 5, 2008,
in San
Diego,
Calif. after
a prolonged
illness. He
was 92 years
old. Bradner
incorporated
science and
ocean
exploration
to design
many notable
ocean
technologies.
He had been
affiliated
with Scripps
since 1961
and was
professor
emeritus at
the Cecil H.
and Ida M.
Green
Institute of
Geophysics
and
Planetary
Physics (IGPP).
Bradner had
a lifelong
passion for
the ocean.
He enjoyed
diving and
sailing and
was one of
the first
Americans to
make a
deep-water
scuba dive.
In 1951,
while
working at
UC Berkeley,
he decided
to spend
some
"weekend
time"
improving
diving
equipment
for U.S.
Navy
frogmen.
Thus began
his
pioneering
research on
the wetsuit,
using a
unicellular
material
known as
neoprene.

Callers during this Show
Charlie from New York
calls and talks about his 55-gallon aquarium, then he says
yesterday there was no power to his house for about
12-hours. Tom and Nevin give some advice about how to deal
with a power-outage.
Jason from Louisiana
calls and says his aquarium clouded up, after he fed a new
food, is this a coincidence?
