Regarding expense, perhaps, but if it only took a few ounces of the
liquid, and if it was re-usable.... Another application (though it's
probably not water soluble) is during a power failure, and all your fish
are gasping at the surface (spray in a bit of PFCs). I wonder how it's
recharged (they mention 'a high FIO2 to maintain high oxygen
concentrations within the fluid', so re-charging might be a possibility).
It can hold up to 20 times more O2 than atmospheric, and what % O2 does
water hold? That will pack quite an O2 punch.

I'm just enjoying the speculation ;~) Isn't that how sci-fi stories are
written. You take a scientific possibility and expand it in time to
include seemingly reasonably commercial applications. If I were to
continue down those lines, then we could have PFC aquariums, using
filters which removed every DOC trace while re-charging the O2 levels.
The fish would be evolved to that particular environment, and there would
be no danger of contaminating local waterways as they would not survive
in water (having devolved the gills to almost nothing). The
hybridization potentials and stocking capabilities would be ...
interesting.

Also consider that PFC has similar CO2 capability and you would have
plant growth which would make CO2 charged tanks look barren (that one I
have more trouble with ;~) It's maybe a good thing I'm more of a
naturalist myself )

It's in clinical trials for humans. Kewl !

I think it would be much too expensive to use for shipping fish,
though.

If he had suggested using perfluorocarbons, then he might have some
credibility. Actually it's an interesting question. What happens
when
you put a fish in PFCs? If we can breath this liquid in our lungs,
then
what effect would it have on fish? I think the O2 level in
perflubron
can be 3 times normal atmosphere, which would make it many times more
O2
concentrated than a fish would ever experience in water.

An obvious application would be transport. A fish could be put into
a
tiny sleeve with just enough liquid to keep it wet. The liquid would
be
a PFC/Ammo-lock/sedative recipe. An insulated reinforced envelope
would
be all you need to ship a small fish anywhere in the world. You
heard it
here first on rec.aquaria.freshwater.misc, and in case such a thing
is
possible, the idea is copyright NetMax 2004 ;~)
