yes, the Integrated Bio-Systems Network with more than 300 subscribers
deals with IBS for sustainable agriculture as well as forestry,
aquaculture, industry and habitat. (join mailing list and see archived
messages at
http://segate.sunet.se/archives/et-w1.html)

you can do all these and at the same time you will generate new products
using wastes by applying the IBS concept.
At the Internet Conference on Material Flow Analysis of Integrated
Bio-Systems, there will be a paper by Paul Adler (USA) on "Phytoremediation
of aquaculture effluents" who uses effluent from fish tanks to grow
lecttuce and basil while rendering and cleaning the waste water for re-use.
I am sure you and many others in this AQUAPONICS mailing list will find
this paper (and others in http://www.ias.unu.edu/proceedings/icibs/ic-mfa
very interesting).
Aquaponics that is practiced in greenhouses has great opportunities for
integration with other biological processes. There is a potential for heat
generation during colder seasons using compost and I am looking for such a
case study. If anyone know of one, please let me know. Co-composting with
vermi-culture is an interesting idea as it can generate fish feed. I am
also looking for a case study that has analysed productivity as economic
feasibility.
looking forward to hear from others too.

Hi Jack:
Have you considered the high potential of anaerobic bio-digestors?
You can get methane, and this means heat.
Besides this, you have a high grade nutrient solution, and a nutrient slurry to
use in soils.

Hello Lee:
Fish wastes don't feed plants, as well as no organic wastes do it.
Fish wastes feed various bacteria, and in this process, bacteria transform wastes
in various soluble mineral salts.
These salts in solution, ionise, and plants absorb these ions.
Bacteria also "produce" many organic compouds with simple chains, that can be
absorbed by plants.
Plants are autotrophic, and produce their own aliments. But why should they not
absorb those organic products, if they are ready for use? They do it.
In my concept, here is the diference between organic and inorganic products.
In inorganic agriculture, as it happens with inorganic hydroponics, plants are
fed with a high controled and balanced mix of mineral elements, ionised in a
nutrient solution.
In organic agriculture, plants are fed with the same mineral elements contained
in soil solution or in the organic nutrient solution, plus the organic
components, wich are result of bacterial work.
Hope this helps you.
Greetings,

Hello Jacky Foo,
Thankyou for the link to IBS and MFA and a wealth of informatiion. It will
take some more visits to digest the new ideas (new to me).
Since so much of this is based on the Materials Flow Analysis - Is there a
link that says what's involved in this so we can see how hard this is to
accomplish.
Again thanks for your time and energy in sharing information
Lee

Hello Raul Martins
Thanks for the insights
I don't believe I have figured out what aquaponics system you are associated
with
Again thanks
Lee
