Temperature is important. A large enough temperature excursion will shock fish
to the point of a disease(s) appearing or even death. The temperature excursion
can also cause a non-beneficial shock to plant roots according to the Colo.
State Univ. extension sevice.

You stated you are in the Colorado Rockies. Hate to be a pain but your
discharge water may be regulated.
1. Whirling disease regulations. If your water is considerd attached to the
State waters in any way the Whirling disease permitting system may be
applicable since you will be raising fish. Last time I checked it was not too
bad. Cost $50/year for permit and you had to get an inspection to certify
disease free.
2. Discharging waters into a public body of water (stream, pond, lake,
river, etc.) or onto any public land is not allowed without a permit.
Been there, done that in Colorado. If you want regs or contacts feel free to
email me.

Hi Jewel,
Sorry for the delay. Several power cuts last night lost me a lot of time
(plus two half written replies), bit embarassing in the context. :)

I think it is, the question is: Is there enough of it coming in?
I get the impression that you intend to start with hydro and introduce
the aqua at a later date, is this right? I am sure the system you
describe would be fine for hydro only - the Paraguay pictures looked
very successful (if expensive) - but believe you may have problems when
you try to swap to fish.
A few questions:
Will the fishwater be filtered to remove suspended solids before
entering the feed lines to your valve trays? If no filtration is done,
won't the trays fill up with sludge over time? I suppose this may be
good, in some ways at least, but would worry about it interfering with
the (rather small) valve. Also, at what kind of rate would it
accumulate? If your trays fill up with gunge quicker than you expect,
it's not going to be much fun cleaning them all out with fruit-laden
plants sitting on top.
How will you remove the solids from the fish tank? Is the throughput of
water really enough to keep the water fairly clean of suspended solids?
How will you remove the stuff that settles to the bottom? Even if you
use some ultra low-tech way, eg you actually hoovering it out with a
siphon on a stick, you're still going to have to put _some_ energy into
it. It's not just solids either, of course, there are other dissolved
wastes which could build up to difficult levels pretty quickly.
I assume you intend to drop the incoming water into the fish tank from a
height to provide oxygenation? The same thing applies here as with the
suspended solids - will there be enough flow to do the job? You could,
of course, simply increase the ratio of plants to fish. If you had a few
thousand plants and one fish, these problems disappear but are replaced
by there not being enough nutrient for your plants, take it the other
way and you get plenty of nutrient but not enough throughput of water.
So, you just need to find a reasonable balance between the two - not too
difficult but the amount of water taken by the plants is going to vary a
lot, as both they and the weather change with time. Seems like this
could cause big problems for your fish?

Yes, it makes a lot of sense. Using the sun to move your water around in
this way is certainly simple and efficient and, as you say, has been
working fairly well on a large scale for quite a while. I understand
your reluctance to complicate matters, especially in view of your
longer-term aims, but what you're attempting isn't exactly trivial and
feel that a totally passive system may not be up to it.
Personally, I would swap the convenience of the valve trays you intend
to use, for additional power generation/storage (solar, wind etc.) and
attempt at least some recirculation so that your plants and their
friends get a chance of helping you with the fish.
Sorry if I seem to be putting a downer on the idea, that is not the
intention and I could well be wrong about some/all of this and even if
not, the are ways round them, some or all of which I'm sure you've
already thought of.
Usual disclaimers and warnings of incompetant/useless advice etc. :)

Tom,
I have had two similar experiences. I only lost 15 fish in
these two, however that is 100% dead.
The fish distributor (Seattle) receives a shipment of fish
from the farm (Idaho) in the middle of the night. They run pure oxygen into
these shipping containers and use salt in the water to ,anesthetize?, the
fish. The approximate 3'X4'X3' containers that my fish were dipped from,
each contain about 250 full sized fish (according to the delivery person).
These poor fish have been traumatized to the max.
I did not know what to look for, in regards to their health,
but we had a heck of a fish fry and still around to talk about it.
I am not planning on buying full sized fish like that again,
too many variables. The fish farmer (Idaho) said that he would send over
fry, in a separate bag floating on the main containers, along with some food
so that I would not be changing their diets when I get them.
Does anyone know how large a tilapia will grow?

Tom,
Slime???? Already???? We didn't get slime for some time. I wouild
reccommend that
you go to a local heating/plumbing store and purchase a "flue brush" - a 3
or 4 foot
long brush that can be used to swab your grid lines. Disassemble them and
run the
brush through to clean them out.
My experience with Tilapia is limited. We tend to get about 10-15% die-off
- I don't
know why - within 48 hours of introducing fish. I am not sure that it is
inevitable,
but we have come to expect it.

Hi All,
Salt is used in the water for a few reasons. Tilapia can survive very well in
"brackish" (partially salt/partially fresh) water. They are commonly salted
to help
preserve the slime coat that all fish naturally have! (a very mild
concentration,
however)
Most of our luck seems to be in the use of "fry". Although they look
horribly small,
under the appropriate conditions, they will tolerate all factors well and grow
HUGE!!!! We have had fish jump from the tank, lie on the floor for hours
and then had
students put them back into the tank and they have survived. As a matter of
fact,
some distributors simply wrap them in wet towels/newspapers print to ship
them and
they recover quickly.
I have seen tilapia as large as 20 inches - maybe even more. We are purging
about
20-30 fish right now and each of them is at least 14 inches (about 16 months
ole).
If you are worried about the condition of your fish, a simple mass/length ratio
caclulation is recommended to check their health.
mass in grams X (length in millimeters cubed) divided by 100
If the total of the calculation comes out anywhere over 1.65, the fish are
in "good
health".

Hi everyone (and Barry)
I think I've found something else that may work well for us, and be of
interest to others. (Barry - thanks for the advice, let me know what you
think of this). While looking up something else in the phone book, I found
a "hatchery" that advertised creating eco ponds. It turns out the guy is
second generation aquaculture farmer, and is leaning towards natural and
sustainable fish growing. He isn't doing the hydroponic end of things yet,
but understands it, and has started experimenting with floating beds
directly in the ponds. What is really significant, is that he sort of came
to the same idea as Tom/Paula, only in a different way. He builds his fish
tanks/ponds with a 12" bacteria laden gravel bed on the bottom! That has
PVC with holes running thru it. He said it keeps the ponds clean, provides
a home for crustations that the trout eat, and the "waste water" from that
is just "nutrient solution", and thus the EPA allows him to send his
overflow into a river. He is primarily doing steelhead and trout, which is
probably better for us to do here in the rockies, since the temperatures are
more "friendly" to them, and we'd be fighting against the temperature issues
with Tilapia for most of the year. He does feed his trout, but has
maintained them with no growth for a month without feed. He says we can
build a "natural" pond habitat for our aquaponics set up, in which the fish
feed as they do in nature! (Did you know that most trout are actually a
variety of Salmon!) Still to consider is if it would be better to take the
raw water from the pond into the standard S&S type growing beds and let the
bacteria do there work there, or hope that his system will be good enought
to feed the plants.

You have big time problems that need immediate attention. Ron Brooks'
comments and questions are right on the money. There is not enough
information available to evaluate your problems. It sounds like you shocked
your system by introducing too much biomass too quickly.
What is your stocking density? If you are above 0.1 lbs fish per gallon of
culture water then you are getting into an intensive system where
environmental parameters have to watched closely. Intensive systems can be
run up to as high as 0.5 lbs/gal but that can be very risky.
If your stocking density is high then I would also ask what is your
recycle rate in terms of time for a turnover of tank water and what is your
waste rate? Your system will need to provide biofiltration and makeup water
to prevent the buildup of excessive levels of ammonia and nitrites. The pH
of 6.8 is fine for the fish but may not be right for your plants.
You mentioned that your emmitters are clogging from solids. If this is
waste from the fish you will need to refine your solids removal mechanism.
Otherwise as solids collect in your growing media they will decompose and
become an oxygen sink. Once your media goes anaerobic you plants will
suffer greatly. The fish may have been shocked from a drastic temperature
or pH change in moving from the live haul truck to our system.
Salt is not used to "anesthesize" the fish, it is used to reduce physical
stresses and to enable more robust physiological defense against stress.
Fish that are transported in live haulers generally are not on death's door
when they arrive at their destination. If so the live hauler would not get
repeat business from his customers. During transport the DO in the tanks is
maintained at a high level and the ammonia is buffered so it will not rise
to dangerous levels. The stresses that the fish experience is usually from
temporary overcrowding and that is not serious. Generally when a massive
die off occurs after arrival it is due to a site specific problem at the
aquaculture facility.
To address Nick's question about size. I have pulled a few males from my
large tanks (3,000 gal) that evaded capture that weighed 4 lbs. They were
over two years old. I would not intentionally grow them to this size
because of the way the growth curve flattens out as they approach 2 lbs. It
is not practical from a feed conversion standpoint to continue holding
them, they eat alot and don't grow much. But they are impressive at this
size. Ron Polka

Bill,
Well, to start, be prepared to kill fish and plants... Sad, but true,
necessity for
most of us who learn by trial and error.
I would recommend getting your hands on a copy of Aquatic Ecosystems, a
large supplier
of most aquaculture stuff. Brush up on your fish biology and needs, buy
some minor
equipment, and contact/net search for local aquaculture/hydroponics peopl in
your
area. Also, contact your local Cooperative Extension - they can help.
Also, colleges
and high schools in your area are most likely doing something with all these
wonderful
toys that we talk about - give them a shout!

Hi Bill,
I would do it the other way around. If you set up a stand-alone
recirculaating fish operation you need to include a bio-filters and
solid-separators which will immediately be disconnected when you
introduce plants into your system. Going the other way, setting up
hydroponics first you only need an EC meter and pH meter in the way of
specialized equipment.

you should know about this one - check out there list of clean up jobsso out of

Whoa, Adriana. Your bio-filter is where your fish waste is converted to
plant food. Why do you want to disconnect it? All the plants saves you is
from doing partial water changes to get rid of the nitrates (the end product
of the biofilter). If your bio-filter is big enough, you don't need a
solids separator at all. The only reason you need to separate and dispose
of your solids is if your bio-filter is too wimpy to do the job. If you are
planning to raise plants in the fish effluent you want to keep all the
nutrients your fish produce, not throw most of it away anyhow.
I would start with a recirculating aquaculture system with a BIG bio-filter.
When the bio-filter is fully functional, I would then add plants to get rid
of the nitrates. This can either be done by channeling the water AFTER the
biofilter through a hydro type set-up or by designing the bio-filter to
accommodate plants right from the start like Tom and Paula's system, or
maybe
a little of both.

I found no listings for Maine , but The closest Trout hatchery listings do
include New Hampshire (NH) and New York (NY)
Trout
Brook (speckled) and Kamloops
Hy-On-A Hill Trout Farm - adult - fingerlings
P.O. Box 308
Plainfield, NH 03781
603-675-9131
I also have listings for in New York
Brown
Brook
Kamloops
Rainbow
As far as Tilapia goes. Most of the farms are down south and will ship
overnight of fry and fingerlings. You need to make sure you are able to
provide the heat for them. In Maine this would probably effect the bottom
line to a large degree.
Let me know and I will give you the name of a few farms

Thanks Ron:
That probably would be something you would need to
know. I have interest in both Trout and Tilapia. I have heard it is
difficult to raise Tilapia in my climate.
Thanks, Chip

Subject: USERS MANUAL!! HOT off the press..

Just coming back from my second GREAT day exhibiting at the second day
at the CWWA (Caribbean Waste Water Association) week long symposium..
I too believe in a more sustainable way! Anyone interested in
irrigation, misting, drip irrigation, aquaponics, reed bed technology,
or microbiology may be interested in recent discoveries in a well known,
ancient, but often overlooked book, one that carries the name of the
reed bed cleaning system my friend and I have set up (similar to Todds
system) to deal with raw sewage, its called GENESIS!!
I think the first engineer to work on this technology got some raving
reviews!!
I hear he was so awestruck when he saw all micro and macrosystems
working in harmony that he coiuld only say, "It is Good!! Real Good!!"
