Subject: discussion on large scale pond aquaponics and aquaculture
From: Jacky Foo
Date: Mon, 3 Apr 2000 08:20:11 +0200
Staring today, the Internet Conference on Material Flow Analysis of
Integrated Bio-Systems will have a paper discussion session on large scale
aquaponics and aquaculture. Floating beds of plants are placed on fish
ponds and at optimal design, it can produce 5.6 tons of fish and 8 tons of
rice per ha of pond.
You will find the paper at
http://www.ias.unu.edu/proceedings/icibs/ic-mfa/song
You are invited to join the discussion with the authors at
http://segate.sunet.se/archives/et-tor.html
or join the LISTSERV mailing list et-tor@segate.sunet.se

Pete,
If you would like to see if wind generation can be of use to this
community, take a look at the lead article in this months Envirospace Ezine
at http://www.envirospace.com/ . There are hundereds of sources for quality
wind generators. There are(as you can see by reading the comments on this
list) many good aquaponics systems out there as well. If you decide to use
biodigesters you will find that they have been pretty well thaught out as
well. The primary obstacle, of course will be time and effort. The more of
these two commodities the community members are willing to dedicate to the
project, the easier it will be. Just make sure that they are the ones doing
the project. If they need you to do some research and coordination, you will
have more than enough to keep you buisy.
Please, notice what Sam said about CO2. It is easy to get caught up
worrying about a bit of invironmental impact hear and a touch of it there,
without considering the impact if nothing is done. Human communities cannot
help but have an impact on the environment. But, this effect can be
minimized by thoughtful use of technology. Severe invironmental impact is
often the result when people feel they have no alternatives(such as slash
and burn farming).
If you will do some research on sustainable community development you
will come up with a wealth of information and possibly some experts who will
give you some sound advice.
Please don't think I am trying to downplay the seriousness of greenhouse
gas production. I am a rather vocal advocate of swithing to alternative
energy sources. you can see my commentary in this months Sustainability
Review as evidence of that. (http://www.eeeee.net )
Paula and others have start up information for aquaponics systems. There
are many choices on what to raise. The community will need to decide what
they want to grow, how they want to grow it and what they want do do with it
after it has grown.

Loren,
Jenny is right. If someone wants to have a greenhouse that is tough
enough to protect their investment in equipment, fish and plants they had
better shy away from PVC. It is by its nature too flexible to be relied on
for this purpose.
The "poly" material she spoke of is probably double or triple wall
polycarbonate sheets which would probably be a good alternative if the
raccoon is not too determined to get inside. If the structure is made of
wood and glass a racoon will claw through the wood if it knows there are
fish to be had. And it could just about as easily claw through polycarbonate
if it was of a mind to do so. The best sollution is to build a trap of 2"x4"
lumber and woven wire or hardware cloth. to trap the culpret. Don't spend
too much money on the trap though. If it is a mature coon it will claw its
way through it as well. But, once it has been trapped it will not return.
You may want to rebuild the trap and try it again though, in case you have
more than one visiting your place.
If anyone wants to use polycarbonate sheets for their structures you can
find a local (reputable) supplier by doing a search for "Greenhouse
glazing". Or look in the yellow pages for greenhouse supplies.
The use of treated beams may give you a sturdy house, but, every
additional inch of wood gives you that much less sunlight and therefor, that
much less production. That is why almost all commercial houses are built of
steel.

Mike,
Corrugated fiberglass would be a good choice. In most greenhouse
applications the lower part of the walls don't supply sunlight to plants or
animals. In these situations you can use plywood backed by foamboard
insulation.

Jason - as you can see from the header (and probably from the copy of your
own message that you received) you are indeed subscribed to the group. What
you saw was an attempt to unsubscribe from a member who had lost track of
the method to do so.
For those of you who might have missed it, or misplaced it, here's a copy of
the current procedures for the list (along with the other comments you
should have received when you first joined). Paula

Welcome to the aquaponics mail group. PLEASE SAVE this message for future
reference if you ever wish to change your subscription or have questions
for the list owner.
***********************************************************
You are subscribed to the e-mail discussion list "aquaponics", an open list
specifically for aquaponics - the combined systems of aquaculture and
hydroponics. All who are interested in learning and sharing information
about this and related topics are invited to participate.
This group, provided by S&S Aqua Farm, will cover any and all aspects of
this exciting subject. We encourage those who have operating systems, are
in the set-up process, those who have a beginning or general interest to
participate.
Tom and I agreed to sponsor this list because we believe there's a great
deal of benefit in being able to freely exchange information with others of
common interest. And, we love to talk about this practice of combining
aquaculture and hydroponics methods. It's what we do, and we feel we can
only learn more by participating in a group where that is the primary
topic.
An open forum mail group was our final decision, as opposed to a moderated
or by-special-invitation-only list. It's provided without charge and
without restriction, other than that which common courtesy dictates. We
really enjoy this list and want it to continue to be a productive forum for
information exchange.
Following are some details and suggested list etiquette to make your list
experience more satisfying.
CONTENTS of this file:
I. General Description of list
II. List Etiquette/Community
III. Subscribe/unsubscribe information
I. GENERAL DESCRIPTION
The Aquaponics mailing list is a general information exchange forum and
cyber-community of folks who share a common interest in aquaponics and
related subjects. We discuss such topics as general growing system issues,
growing your own food, water conservation and energy systems, agriculture,
food safety and nutrition, environmental issues related to aquaculture and
agriculture, ag technology, plant and aquatic species, etc.
Although the emphasis is on aquaponics, you don't need to have a system yet
to participate - in fact you may be interested because you think you'll be
healthier, because you want to be easier on the environment, you enjoy the
rewards of self sufficiency, or you want to evaluate a lifestyle change.
Whatever your abilities or reasons for being drawn to this list, you are
welcome. Any topic may be discussed. In order to bring the topics into
the areas you want, we encourage everyone to post their queries,
observations, comments and suggestions for how this type integrated system
should, does or might work.
** Other Boring Technical Guidelines **
*************************************************************************
1) Only subscribers may send posts. If you are subscribed under one email
address and try to send a post from another, your post won't go through.
2) If you change your email address, please unsubscribe your old address
before changing, if possible! If not, please contact us at
snsaquasys@townsqr.com, and we'll take care of it.
3) If you are going away for an extended period and your Internet provider
places a limit on how many messages you can receive (AOL and Juno, for
example), please unsubscribe until you return and are able to keep up with
your mail. If your mailbox is always full it creates more work for the
list server and administrator.
4) When posting, especially when replying to someone else's post, please
check your TO: line and make sure the address matches the one above.
Sometimes your mail headers may cause the "Reply" option to reply to the
person privately when you intend to address the whole list. Please just
edit the TO: line and correct it in this case. Do NOT use the "Reply To
All" option of your mailer software, as this will cause multiple copies of
your message to be sent to the list and create more work for the
administrators. :-)
5) Please don't clutter up the list with excessively long signatures or
quote an entire message when replying to it (if you can help it!). Quoting
only relevant points in the message will be very helpful to the discussion.
II. LIST ETIQUETTE/COMMUNITY
This list is primarily a source for exchange of information on aquaponics.
However, topics you believe to be of general interest are encouraged and
invited. We only ask that you consider the topic and length of the post
before sending. If questionable, please send a summation and request
private inquiries.
We are a highly diverse group from many different countries, cultures and
backgrounds, and do not identify as a whole with any particular religion,
creed, political party or anything else. Please accept reponsibility for
keeping the discussion respectful and reasonable, even in disagreements, or
take your discussion off-list. The variety of needs, plans, proposed uses,
sizes of
operation, locations, interests and "experience" levels expressed by those
who've written us indicate that there will be times where this may be
necessary.
Advertising on this list, and most others, is seriously discouraged.
However, we have several members whose products or publications are of
probable interest to a large number of our subscribers. In order to enable
the group to become aware of and evaluate these items, we are initiating the
following policy:
Monthly Member "Ad" Day will be the 15th of each month. Please observe the
following guidelines for courtesy.
1. Preface your subject line with the word "AD".
2. Please keep posts to minimum size to convey your message.
3. Ads need not necessarily pertain to aquaponics; related topics/referrals
are accepted.
4. Do not post graphics.
5. Do not include attachments.
6. Please, use good judgement on content for our international community
of members.
We hope this will allow some leeway for our members with commercial
interests in aquaponics, those wishing to report on items of general
interest to address the group, and be of benefit to all subscribers.
*************************************************************
Although this list is unmoderated, there are some things which will cause
your name to be deleted from the group, so be warned:
1) SPAMMING the list with any advertising material other than the
designated Ad Day. We do have people on the list who have aquaponics-related
businesses, and it is acceptable to post information about the business in
response to an inquiry about your particular line of work, to mention it in
passing if you are a regular contributor, or to post a link to a web page
describing your business. Spamming is considered to be either information
that is obviously a non-specific "form letter" that is sent to many
different places, or references to your business in *repeated* postings
that are unsolicited (no one on the list asked you for the information).
2) SLANDER of another individual on the list. Stating a negative OPINION
about someone is not considered slander, although we certainly ask you to
exercise good manners and not resort to name-calling. Slander means
accusing a person of something you cannot prove is true, e.g. that another
list member has a drug problem or anything that may similarly reflect badly
on the person's character. Publicly posting private information about
another person, e.g. addresses, phone numbers or family members' names,
without the person's consent is also considered slander.
3) Sending ATTACHMENTS to the list. Sending an attachment to everyone,
while you may think it contributes to the discussion, only bogs down the
server and costs many people time and frustration in downloading data that
they may be unable or unwilling to open anyway. Attachments can contain
viruses, so many people make it a general policy not to open any attachment
from an unknown source. So if you have an attachment you think it would be
worthwhile to share, please just post an announcement and email it
PRIVATELY to those who ask for it, e.g. "Hey, I've got a great .GIF of some
drawings of (whatever)! Email me if you'd like a copy!"
Note also that many email programs these days send attachments without your
even being aware of it. If you like to play with fancy formatting,
signatures, greeting cards, or sending HTML code along with your email, do
NOT do so when posting to this list! Please make sure your mailer software
is configured to send text only. Of course, if you do accidentally send
attachments, you'll be sure to get a chorus of hollering from list members,
and can contact your Internet provider for help if you don't know how to
stop the attachments.
