Good luck, Chris. Re telephone conversation: the pumps we use are called
Pedrollo and if you give Ray a ring at 011 329 6852 he can fill you in on
the specs and supplier in Cape Town. I have mailed Alexvw to get in contact
if he should wish to do so.

Hi Ralph,
Man, Oh Man
.I just want to be a lurker and not say anything, but that
appears to be impossible. I wanted to say something before in relation to
your catfish, but didn't
.now, I feel guilty.
What Bruce says is absolutely true. I stocked catfish in my pond 3 years
ago. I have a very small pond. It is only "maybe 1/4 - 1/3 acre". It is
well aerated in the winter time, but still covers in ice except for a very
small area around the aerator
.the catfish survive and breed quite well.
"Cats" are very hardy.

Ralph Just so you know for the future the main and almost only cause
of ick is thermal shock caused by too rapid of a temp. change.This
happens most often when aquatic animals are not floated in the bag for
long enough to gradually equalize the water temp. of their bags water to
that of the tank water that they are to be released into. And It is the
same sort of shock that gives us colds for not putting on our coat to go
out to get the mail or something like that.
Your catfish can live quite well in cold water under the ice so
don't give up but next time have them put fewer to the bag so that you
can flote them for say one hour before letting them loose and you wont
get ick again

No, No! Bacteria are not scary. Bacteria are everywhere. Ubiquitous!
Pseudomonas sp. is everywhere on the planet.
You have a happy layer of bacteria on your skin and a Gwadzillion of them on
your hair throwing little microbe parties
.As you move around in the
air
your hair is like an air filter collecting Gwadzillions of bacteria
every day
.that is, if you have hair on the head
.nevermind
The key is to try to control the environmental conditions as best as
possible and not let the opportunistic little gremlins enter at the gate of
opportunity that one may have left wide open.

I live on the olympic peninsula in western Washington. My problem is that
I've
been buying fish food through pet stores, where even online and in bulk the
best deal I can find works out to almost 5 dollars per pound.OUCH! Surely I
have missed something. I would like to find a local/regional source of
commercial fish feed, but due to the small size of my system, an appropriate
method of storage is also needed.Ideas??

Thanks Ken,
But that didn't really answer my question. My question wasn't who did the
study and how good they are, but what were the testing methods. Some people
might have read into my question (which is easy to do in emails), that I was
questioning the results or who did the study, I wasn't. Being a computer
weenie and information leech, I wanted to know more about the study.
Sorry if I implied otherwise.

Chris,
There may be something else to consider in closed loop aquaponic
operations which are the BOD and COD issues. How much extra O2 demands are
place on a system. I wouldn't mind seeing a range of experience with
aeration equipment regardless of studies performed under ideal lab
conditions. Field variance and site conditions will through a curve into a
3rd party study. A paddle type aerator might be the perfect solution in a
larger operation but not practical in a backyard or in a small greenhouse
with a 500 gal tank. Just a few thoughts on this question

Brother-Mike,
As I mentioned, we have 6 identical aquaponic units where we will conduct
our chilling research. We will be comparing "high-tech" electric chillers
with "low-tech" homemade evaporative coolers. We will also have 2 systems
with no temperature regulation, our controls. We anticipate the cost for
running the electric chillers will be astronomical and we are shooting for
success with the homemade units. Don Bailey can give you more specs if you
would like. I'll be plating roots throughout the experiment looking for the
presence of Pythium fungus species. Hopefully, as we drop below 76F we will
see the fungus disappear. We'll see and we'll let you know.
Always yours,
Charlie

Charlie how will you try to cool the root zones? By what methods of
chilling?
Anyways mon.Jus chill
. and cool breeze to you

Carol and Arlos,
Thanks to you both for your input on Worm Systems. I'm leaning toward
builing my own unit. The websites mentioned should provide plenty of
vermi-info.
Respects!
Ted,
Big t'anks for your in depth explaination of mineralization and
nitrification considerations. That one goes in my files.

Jim There is a whole range of cold water fish out there for you to
pick from any fish native to north America should work for you.

Darren Any feed store that deals with live stock growers will get it
for you than you just keep it in barrels

Ted Margi thinks it was you talking about the giant earth worms
(that I saw in the national geographic magazine when i was a kid )from
the Zambize river dranage They grew to about 5 or 6 ft. and were hunted
buy the natives and cut up into steaks of about 6 inches acrost and were
fryed and eaten

Margi I am no Journalist just a guy with a life long interest in
Africa among other things and a near photographic memory.
Can you get Belhousea from swimming in the Zambezi,Do you still need to
be guarded from crocks buy rifle men when swimming in it. And what do
you call that worm that grows out of the natives and that needs to be
slowly wound up on a split match stick to remove so it does not break
and kill the native buy blood poisoning

Pablo If you can get a supply of Pacu do so they grow very fast and
are very superior eating and you can feed them old fruit and anything

Bruce,
What you say sounds great. Something like an acuatic porc. In photografs
from the site I posted, it looks yummy. I've never eaten it. On the
southern part of the country, by the sea, sea food is what you can get.
Eventually that may be the marketing difference that may sell. As for now,
I'm more concearned on how to get them alive to my kitchen.
Wuold it be wrong to consider half the density of tilapia?
The same source I took the info from, asignes DO 0,8 mg/l for tilapia, and
1,5 mg/l for Pac=FA. I know that to raise them well 4-5 DO is needed for
tilapia but, since it seems no one has tryed intensive fish raising in
acuaponics with these species before, provided I could get 4-5-6 DO
expected in an S&S system.
What I need to know if this kind of reasoning is valid.
Since, it is usually asigned a density around 1/4-1/2 pound of Tilapia per
gallon of tank water, would it be correct to think about 1/8-1/4 for Pac=FA?
I don't now if oxygen is THE limitant parameter for fish density, provided
you mantain water clean, and feed them well. Given these, I could only
think of oxygen needs and behavior.
The latter if no literature is aveilable, i guess i'll have to watch and
see. But thats what we do since kids with our new toys or new pets getting
to know them. Spend lots of time with them. That's part of the fun.
Thank you for your coments,
Pablo
