I think you will find that redclaw need a warmer climate than you have in
Victoria unless you are able and willing to heat the water in winter. My
suggestion is for you to stick with yabbies which are adapted to your area.

The wall is 16 inches high but the water depth is only 12 inches. A 4-inch
lip provides transplants a little protection from wind in our ourdoor
system. Since we use numerous 3-inch airstones under the polystyrene sheets,
a shallower depth wold not allow enough contact time for oxygen to diffuse
from the bubbles into the water. When you raise tomatoes, the roots
certainly take up all the space. We don't use rockwool. We use Promix BX, a
peat-based potting soil for the transplants. It works great, but I don't
recommend it because peat contains pythium spores. We are going to switch,
but we haven't decided on a new media. Any suggestions. We've raised a wide
variety of plants such as lettuce, tomatoes, chives, basil, marigolds, etc.
We use either high or low density polyethylene liners (HDPE or LDPE). About
20 mil thickness is adequate although we've used up to 60 mils which is
overkill. The liners are black. Jim R.

What are the needs of crayfish for reproduction? Can they
be met with little change to the general conditions of the average
freshwater system? Do they need a medium to deposit eggs in or do they
carry them with them?
Your responses will be appreciated.

Jim,
I understand now what you mean when you say that a gravel system won't scale
up. If you are envisioning a bed 30ft by 400ft full of 1" rock -- wow.
However, in temperate climates, year round growing requires a green house
environment. No one uses 30ft wide beds anyhow. One has to be able to
reach into the beds to plant/harvest/etc without walking on the growing
medium. Four or five feet is about the maximum width of any greenhouse bed.
One inch rock is too large for a good biobed system. Pea-sized pebbles are
about optimum. You want to maximize the surface area in the bed and yet let
it be coarse enough to allow good drainage on the drain cycle. With the
smaller gravel, one can just stir things up to remove any stubborn roots
without emptying the whole thing. Its too bed you cannot get proper biobed
sized gravel in the Virgin Islands or your experiences with biobed systems
might have been more pleasant.

Wendy, I've been told that there are float systems this big. I've never seen
one. I assume they are in very long greenhouses. They are probably used for
lettuce and other greens. It's easy to harvest just by pushing all the
sheets to one end and harvesting from that end. We do that with are smaller
systems. Transplant at one end and harvest from the other. A Ccommercial
operation close to the university has beds that are 114 ft. long by 12 ft.
wide. You can move floating sheets with the push of a finger as though they
were on a frictionless conveyor belt. Jim R.

Uwe, I think you know that managing this list is not my primary occupation.
What I'd suggest to the group is -- if you opened the attachment with the
fireworks, I'd say it's pretty certain that you now have the offending

I have a three foot plastic "breeding pool" inside of my greenhouse that
is virtually going to waste. Two or three goldfish swimming around it in.
It has solar heating, and two backup electrical heaters to keep the water
temperature at around 27 degrees C. I'm sure Redclaw would love this

They are 1) tastier, 2) jucier, and 3) put up with a wide range of
pollution levels, light levels, and best of all - climates. Never put them
in a blow up pool though, they don't get the name Cherax distructor for no
reason (I learned that several years ago :)
They've also got a thing about climbing up pond walls and going to
explore. One day I got nipped by a "runaway" yabby at 2am in our bathroom.
Something that bites that hard when you're half awake and in complete
darkness is very, very scary. Lesson learned - never leave an open yabby
tank inside your house.

Subject: Pool turning into Reality
From: Michael Strates
Date: Tue, 9 Feb 1999 18:43:42 +1100 (EST)
Folks,
I was chatting with my father re: the possibility of constructing an
aquaponic swimming pool when he suggested to get a several thousand
gallon plastic rainwater cistern, cutting the top off that and using it as
a deep swimming pool and also as a small aquaculture pool.
The one we saw is about 6ft deep, and has a diameter of about 6.5 feet. I
want to install it inside of my greenhouse. Hopefully we'll be able to
purchase an old cheap one ($300-500) from up country and the aquaponic
pool should turn into a reality in about 30 days!!
So, here come all of the questions. If I fluke a working pool, then I'll
include a whole chapter in the collabrative aquaponic archive about it.
My main concern is any pathogens which might get in the water. So far, my
results with chlorine dioxide has been pretty bad.. 7/10 fish died after
my dose per gallon exceeded one teaspoon. This wasn't enough to keep the
algae and pathogens out, by the looks of things.
I was thinking about making a sand filter out of a 44 drum to keep the
water clear.. is this really neccessary?? and, I'd like to know if UV
sterilization (I already have a 70W tube and can get them cheaply) would
be the way to go.
I'd also be interested in H2O2 injection, if its practicle. Does anybody
have figures on how much hydrogen peroxide fishes can stand, and whether
the costs are practicle.
I heard somebody say that the used aquaponic effulent is as clean as
reverse osmosis filtration, but I really do find that hard to beleive.
Does anybody know how many cfu's of certain bacteria are left in their
used solution outlet, or does anybody want to find out? It'd be /really/
helpful.
Also, keeping fish in the pool? What kinds of fish would be practicle. In
the summer time, the water temperature could even get to about 30C. In the
winter, the temperature could drop down to 25C.. could goldfish stand the
thirty degree C temperatures? Know of any fish (don't suggest talapia, we
can't get them in Oz.) that can?
Sorry if I sound like a cop :)

Hello Alejandro, Hi Aquaponic´s folks:
Well my experience is based in Macrobrachium rosembergii, and with this
speciae we dont have troubles with polyculture with tilapia. We use a low
density in prawn-tilapia (5/sq-m and 0.25/sq/m, respectively) At the
fourth month we have 28 gram mean weight in prawns and 300 grams maen weight
in tilapia!!

lars,
To answer your question from what I have and what I have seen.
In my system I am setting up it uses the NFT and an ebb and flow system
ideas. I used 4" PVC pipe(main pipe) with 2-1/2" holes cut on top 9"
apart, then I placed 2-1/2" length cups (with holes in them) into the
holes. The cups are then filled with clay rocks made for hydroponics. I
have the water turned on and off intermitantly. The water is pumped
into the one end, flows threw the pipe. And on the other end I have a 2"
vertical stand pipe inside the 4" pipe(main pipe) so that the water will
build up within the Main(4" pipe). The stand pipe also has a small weep
hole at its base(inside the main pipe)so that when the pump is in its
off cycle the water will slowly drain competely out of the main pipes
allowing oxygen to the roots.
This is how I do it.
In some systems I saw at Crop King they have gutter troughs with flat
bottoms, they place their rockwool cubes with the seedlings in the
troughs and they sat cubes right on the bottom of the gutter with a slow
flow of water flowing threw.
Can anyone else give me feedback on the bacteria questions I have? I
would really appreciate any imput before I start my system. Thanks
