Wanted to let you know that as of Noon tomorrow Weds Feb 2 2000 I have a new
email address. With my local cable company offering DSL cable internet at
10Mbps vs 56K and only 6 dollars more a month. Well needless to say I want
speed.
Ok my new email address is wolfwalker@oberlin.net
Please excuse this if you get it more than once as the easiest way to get
the word out is by mass emailing it. BCC of course :)

This list has been so quiet the last few days, I was beginning to think that
EVERYONE had unsubscribed. But I checked the roster, and we're all still
here:>)
This might be a good time for those who are new to the list to post a short
introduction and whatever question(s) are most important. Let us know a
little about you and your plans (or status of your system); and if you have
questions, post them as well. There is no shortage of expertise in the
group, and I think we'll see some interesting discussion.

I live in Ohio and have no experience in aquaculture or hydroponics,
but want to put in a greenhouse employing these techiques.
The ideal system for me would be one that would require
as little fossil fuels as possible. I think tilapia would need
warmer water than ours would be in the winter time, (comment
please) so, I'm trying to find info on raising catfish in 500
or 1000 gal. tanks for the hydroponic garden. I'd please
like to have someone discuss this subject and/or mentor
me in this project.

swing shift(change shifts every 2 days) Wife Cathie,daughter just left for
the US Air Force last tues and we hopefully will go to Texas for graduation
from boot camp. Going to be a grandpa in a couple of weeks and again in
August,daughter is getting married when she comes home on leave in July
I have a 30 x 80 greenhouse that has been idle for 3 yr because the semi
took all my extra time its gone now. Sad thing is the greenhouse money seems
to be flowing into the wedding fund now,dont you just hate it when that
happens.
Been lurking here for the past year reading and learning thanks to all of
you
Didnt mean to write a book but here I am

Howdy, D. Bennet
I had a dream last night about really big catfish in an aquaponics tank, so
maybe I am supposed to chirp in here. I have designed, set up and operated
aquaponics systems and I am still working on my next great, and better
design, so I would be glad to try to help to a certain degree....but just
keep in mind that I have my own strange permutations to compare to and
recommend from.... based on my local experience, climate, market, fish and
plant preferences, you name it. So take all this with a big grain of salt,
etc.
Part One:
CONSERVATIVE / IMAGINATIVE DESIGN ASSUMPTIONS
(I am composing this off the top of my head, so if I leave stuff out or
exaggerate things beyond the pale of your experience, I know you aquaponic
warriors will fill in the gaps or correct me here....)
1) Harvest 250 lbs whole catfish from a 1000 gallon tank in 12 months
2) Stock fingerlings and feed them for 12 months to a harvest size
3) Good harvest size ranges between 0.75 lbs and 1.25 lbs.
4) You could grow 1 lb fish/gallon, but with much more
energy/technology/costs
5) Assume $15 to $25 to buy, transport, and stock 250 catfish fingerlings.
5) Assume feed to conversion ratio (FCR) is about 2 to 1.
6) That means 2 lbs fish food results in 1 lb whole carcass fish flesh in 12
months.
7) Assume cost of feed is $0.30/ lb (high end of price spectrum).
8) Feed cost for 1 year = 2lb/lb x 250 lb x $0.30/lb = $150.
9) Assume 500 ft^2 greenhouse to do this.
10) Assume 200 ft^2 growing bed of gravel, perlite, NFT,what have you.
11) Assume 0.20 -0.50 lbs edible "produce"/ ft^2 / month(28-35 days)
12) Think about the range of $1 to $10 / ft^2 to build your 500 ft^2
greenhouse, including tanks, pumps, heating, lights, environmental
control....this is highly variable depending on how fancy you get, how
resourceful you are at scrounging, your construction skills, local
availability of salvage materials, labor availability, family participation,
inventiveness, etc..so let's go with $5 / ft^2, which is still WAY high in
my opinion for a small home-built aquaponics greenhouse.
13) Assume $100/mo energy+water+debt service+consumables for the 500 ft^2
