Hi Bruce
A good thought too. Unfortunately, the salt pans in our region are used for
commercial sea salt production, and although they teem with brine shrimp,
the holding companies will not consider a side line artemia business. I
have even go so far as to get the Head of the Icnthyological Department at
the local University to approach the company directly, to no avail - their
core business is salt and their minds are closed to alternatives.
Microworms won't do for this seasons expected harvest of >2 million koi, we
need a more flexible solution!

Hi Mike
Many factors affect the behaviour of distinct groups of fish. If they are
in cages I will take the liberty of assuming they are in a common water body
and therefore pollutants (including nitrogenous wastes) are unlikely to make
some jumpier than others. Light intensity can affect them, your approach
may be seen from some distance by one group and not the others who
consequently take fright, bigger cages and clear water can cause fish to be
nervous, a predator in the cage will make them nervous, etc. etc. etc.

Leslie

Hi Arlos
I have a maths problem I have been grappling with for a while and I hope
you may be able to help.
Arlos said
> I eat math for breakfast. I'm going to tackle this soon.
I have a PC computer which monitors various tank parameters, one monitoring
the water level during the System cycles. The position sensor I have built
is very cheap and easy to build. Except the computer returned level value
is not linear due to circle geometry. Simple harmonic motion maths could
solve the problem. I have been looking for an equation to manipulate the
data in Visual Basic 6 to give the correct Tank level.
I will post details if you could help me with this.

Marc,
That period in the mid-late 90's was a dark time for the natural foods
business. it lead to flash pasteurization of all raw juices. Odwalla, one
of the larger juice companies here in California was at the heart of a
controversial attack due to a number of outbreaks of e Coli related
illnesses. tied to apple juice. Same with the article in point of e Coli and
salmonella outbreaks tied to sprouts. I cracked up reading the suggestion
that sprouts be cooked before eating. At any given time you can find food
poisoning running through the population. In defense of Odwalla, there was
never any trace of e Coli found in any samples or equipment yet all had
drank Odwalla's raw apple juice. It was never fully proven that fallen
apples were used but the company paid the damages incurred in a number of
suits. They had moved their bottling operation from Half Moon bay, CA to
Dinuba, CA where if anything, I would have suspected the water used to rinse
apples. I've set up spray bars at several large processing plants using
ozinated water for this reason as many crops come in contact soil that has a
greater potential for contamination, like tomatoes. The same potential could
become an issue for the group after reading the thread about seeding the
biofilter with animal waste. I don't have the knowledge to say whether any
harmful bacteria or virus could survive and thrive in an aquaponics
operation? I would be interested to hear what anyone is doing that produces
a finished and packaged product for market in terms of handling from
sanitation between growing cycles to weighing, packing and sealing. where
the potential lies to introduce a pathogen? Just a few thoughts before the
morning coffee

Arlos,
I remember the backlash it caused against sprouting and health food
in general.
I eat sprouts and grow my own
.their daily rinses are in ozonated
water. We have to be as conscious of sanitation as the rest of the
food industry
probably more so because there are those out there
that would love to see any form of alternative agriculture fall on
it's face.
It's a sad commentary on journalism but shows like 20/20 have done
segments on organic food that were full of errors, yet the story
of what's going on in today's factory-sized slaughterhouses that
is contributing to much of the e-coli outbreaks was pulled by
two different networks. The USDA stamp is a joke. As one inspector
stated
."I'm expected to inspect a chicken in less than 3 seconds.
The line moves so fast, I barely have time to pat them on the ass".

Hi Mike
Below is an extract from an online report titled :
SANDEC Report No. 6/99
Duckweed Aquaculture
Potentials, Possibilities and Limitations
for Combined Wastewater Treatment and
Animal Feed Production in Developing Countries
Tony Cooper.
Duckweed for Human Consumption
Wolffia arrhiza has traditionally been eaten in Myanmar, Laos,
and northern Thailand (Bhanthumnavin and McCarry 1971). The
duckweed cultivated in these areas is sold on local markets,
however, since it is regarded as the "poor man's food", interest is
apparently declining.The use of Lemnaceae for human consumption has
surprisingly
not spread to other regions of the world. A possible explanation
could be its high content of crystallised oxalic acid which has a
negative effect on the taste. Another factor contributing to the
low interest in duckweed as a potential food product for human
consumption could be attributed to the fact that it is difficult to
separate associated (pathogenic) organisms such as worms,
snails, protozoa, and bacteria from the plant (Gijzen and Khondker
1997).

Ahhhhh

sorry bout that booboo

Well maybe we all learnt something? See I was figuring if U used coffee
as a filter, you might have removed something that was locking onto your
phosphate or was needed to lock onto it
. hence showing a flawed

As you see from the article the coffee is said to be charged differently

Actually, as a result of the "sprout scares" of a few years ago,
sprout production is regulated under the Food and Drug Administration
as a "processed" food in contrast to other agricultural products under
the purview of the USDA. More regulation, more inspection, more
liability, more cost. My question is this:
"What is the definition of a sprout?" If I grow peas as shoots and
cut them at 3" and sell them without roots or seed pods, are these
considered sprouts? What if I grow them to 6+ inches? In my mind the
latter are just baby plants, not sprouts, but maybe some regulator
will decide otherwise. What about products like wheatgrass which are
sprouted in soil or some other media - are they sprouts? What about
microgreens?
There is a good discussion of sanitation issues for sprout productin
at http://www.sprouting.com/commercial.htm. Mumm's is also a good
source for reasonably priced organic seeds.

How accurate does it need to be? What (roughly) are the angles of the arm
(from horizontal) at high and low water-levels?
Here are some figures from a _very_ simple model:
0, 0
0.05, 2.866
0.1, 5.739
0.15, 8.627
0.2, 11.537
0.25, 14.477
0.3, 17.458
0.35, 20.487
0.4, 23.578
0.45, 26.744
0.5, 30
0.55, 33.367
0.6, 36.87
0.65, 40.542
0.7, 44.427
0.75, 48.59
0.8, 53.13
0.85, 58.212
0.9, 64.158
0.95, 71.805
1.0, 90.0
First number is distance between water-level and pivot with the length of
the arm being the unit (ie at 0.5 the water-level is half of one arm-length
below the pivot). Second number is angle of arm from horizontal. Paste these
into a spreadsheet and it's linear(ish) up to around 30-35 degrees.
This is based on 2 linked points. One is the pivot, the other the "float" on
the end of the arm. The float has no size as such - that end of the arm just
rests on a surface (water-level). A real float seems likely to distort the
graph further. Also, I think that the balance of the arm changes things -
likely to be other factors too.
Point is, I believe it might be easier (and more accurate) to measure
response of the actual device at as many height intervals as you've patience
for and use software to interpolate between them, than to try to find some
function that approximates it.
Could be wrong though. Hope this helps anyway. Let me know if you want a
smoother version of the numbers above.

introduce the 50 micron particles of the bale of straw to the charcoal
pellets in controlled, timed, doses
.and if I do my best to distribute
each of those doses over the largest area possible, instead of just on 1
square foot of big ole' coals
and do that "dusting" over an extended
period of time, instead of dumping a bale of hale on some big ole'
coals
.what might happen? And how does that contrast with scenario one?
What kind of redox potential could be charted and graphed if I brought in
oxygen, then, dampened off the oxygen, then brought oxygen in again, and so
on, like the surf or tide, or the breath, or the heart beat, to this kinda
primative BBQ charcoal analogy? Bellows and Dampening
.Bellows and
Dampening
.
And how do you think it might effect the dynamics of S, Fe, P, Mn, and other
cycling considerations in aquaponic systems if you replace the concept of
fire with bacterial activity and respiration?

Chris,
Welcome to the group. Let me be the first to welcome you. I live on the
left coast and work in the water industry. My interest in here is to reuse
waste water for aquaponics and aquaculture. I design, build and install
water processing equipment. Anything I can try and answer for you, more than
happy to attempt. I think everyone is fairly civil and only a few are not
yet house broken

Leslie whats to stop you from going to the salt pan area once a year
when the Artemia are laying their eggs with a boat and a length of
floating rope to collect your own ? The eggs float on the surface in
rafts of scum (eggs)so all that you must do is suround an area with the
rope concentrating the eggs for your net and scoop them up.
In an afternoon you should collect about 50lb to 100lb or so! .At
todays prices that is no small change and I just bet it pays for your
trip. Go ahead and let dumbo collect his salt .You can lead a horse to
water but ya can't make make him drink sorta applies here.
What do you think about the Sumer records? Its almost as if they
were writing about a time like our time now but then you realize that
we've been through 4 or 5 dark ages since then.And their records are
absolutely the first and oldest written records of mankind pre-dating
the Greek and Bible by at least 100,000 years by their count. It seems
that they were our Arch type.

Hi Leslie,
You are so much more than just a pretty face. I'm just fascinated & amazed
when someone uses "ensure" instead of "insure". I'm amazed. "Maybe it has
something to do with "sexual"
.I don't know.

Hi Brent
Use of wind power is great. I would use the wind energy to charge batteries
and run the pumps off the batteries to ensure a constant flow of water.
