I am particularly interested in the system too and wonder if any
quantatitive analysis of the material and nutrient flows has been done for
this system; i.e. what and how much inputs is made into the fish tank
(feed, water) and its output (water quality and fish) as well as the
nutrient flow for the beds. Is the bed a gravel bed that serves as a mic
robial filter or does it have plants on it too ?
If answers are available for the above questions, this would be an
interesting paper for presentation at the Internet Conference on Material
Flow Analysis of Integrated Bio-Systems
(http://www.ias.unu.edu/proceedings/icibs/ic-mfa) .

Hello Jacky Foo,
The Speraneo's can answer about what tests have been done on the water
coming and going from the fish and plants I would be interested also.
I am thinking that plants along with bacteria are in the gravel and this is
the filter. It is also for converting amonia and for "composting" fish waste.
It would be tremendous help to know nutrient contents. I will check out your
web site. It will probably answer this - but are you doing integrated
bio-systems for sustainable agriculture.
I would like to understand in pretty much detail how the fish waste products
are fertilizing the plants.
As you study integrated bio-systems -- Do we maintain quality as we increase
the quantity in the system ie growing high conc.fish in a small space for
one possible ex.
If it follows that the inputs (fish feed) must be cheaper that the outputs
(fish and plants) than the material flow analysis would be very beneficial to
us trying to learn how to do this.
Thanks
Lee
