to the economically sound, environmentally compatable growth of the
aquaculture industry.
NEWS RELEASE
AQUAPONICS COURSE
Aquaponics interest is increasing globally in response to more emphasis
on resource management, sustainability and waste management. It involves
combining of aquaculture and hydroponics for mutual benefit. To help meet
the demand for instruction, a practical course in Aquaponics will be held in
Bryson City, NC, November 6 - 9, 2001.
Lecture and AV presentations will include components of aquaponic systems,
fish and plant selection, balancing fish/plant production for efficiency and
optimum
yields, utilizing old farm and other buildings, small scale pilot projects,
systems design, natural pest control, meeting organic standards, economics,
specialty
markets for higher profitability and accessing technical assistance and
information.
Sites of interest, including a thriving commercial hydroponic lettuce greenhouse
operation and a watercress production operation utilizing trout farm
effluent water
will be visited.
The lead instructor will be Gordon Creaser, who has been involved in hydroponics
for over 40 years and travels world-wide as an aquaponic consultant. He is well
known for his down-to-earth practical advice. In addition, owners of
several successful aquaponic facilities will share useful information
concerning the design and operation of their systems. The class atmosphere
will be informal, allowing plenty of time for questions and
personal attention.

Arlos
I have been keeping 10 river mussels in a 90 gal. tank full of
tilapia and 2 large bullheads since June 12th of 2000 and the first one
died on May 6th 2001 and I lost the second one on monday .
I think this was due to rising summer temps. lowering the Oxygen level
Because I keep this tank way over stocked but the bullheads have been
trying to suck up the mussel feet all year so they might be the
culprits.
The mussels have all at least doubled in weight in the last year they
must be feeding off of fish waists filtered from the water column.
You should know that in the Aquarium trades mussels are said to be
hard to keep alive but I find that in this polluted test tank they have
done ok so it seems that they require a less than pristine environment
I all so in the past 3 out of 5 years have built and maintained
fresh water Reefs using rock from a flooded Quarry that is covered with
Zebra mussels from the quarry . The mussels are hanging on the rocks
attached to one another like shag rug in the quarry and I liked the
looks of them so I made the effort .They were cool looking in the tank
and the fish grew well and breed normally (again in a polluted over
stocked test tank )
1)They are light sensitive so keep them in the dark
2)Don't thermal shock them they are sensitive to radical temp change
upon being placed in a system
3)IF they release their holdfast from the rock all is not lost they
will reattach on the bottom

>From "Biological Filters, Water Quality and Fresh Water Clams" by Michael
Stewart Connor, Journal of the New Alchemists, 1980:
"Experiments at Auburn University by H.S. Swingle showed that fresh water
mussels can increase the carrying capacity of largemouth bass-bluegill
sunfish ponds. For five years the average standing stock of fish in a pond
contain mussels (Lampsilis clairbornensis) was 1.5 times greater than the
control ponds. Swingle felt the difference in fish production was a
function of the filtering action of the 40,000 mussels on the two-acre pond
bottom. The filtering net of a mussel has a large absorptive (also
adsorptive
TG) surface that can remove dissolved organic compounds and
improve water clarity".
"Similar results were found in growing catfish in 170 liter tanks a tht e
Fish Farming Experiment Station (Stuttgart, Arkansas) where James Ellis and
Dewey Tackett compared the filtering effect of using 30 mussels (Anodonta
spp.) instead of regular water filters. Catfish in the aquaria containing
mussels grew 1.5 times as fast as those without mussels. There was no
significant difference in water quality parameters in the the tanks" (That
is, the parameters that they were monitoring
.TG).
"Some fresh water clams are sold here, for instance smoked Corbicula at
about one inch in width. Introduced to the country from China, Corbicula is
considered a nuisance in the United States because it clogs irrigation
canals and intake pipes. But in Asia, particularly Taiwan where 5,000 acres
are used for Corbicula culture, it is eaten as a delicacy as well as for its
medicinal value in the treatment of liver disease. The Taiwanese commonly
raise them in polyculture systems with bighead, silver and grass carps.
Clam growth-rate depends on size, local environment and the amount of food
available. Growth ranges from 0.7 - 3.0 % wet weight /day with an average
of 1.5%, fast enough to harvest them after one growing season."
Beware of the man, you experimenters. Corbicula is outlawed as an exotic
species in many states where they can invade natural watercourses and
overwinter. You might get an exotic species special permit if you can
contain these guys within your greenhouse system and ensure control of
accidental release.

And as for the Man warning it goes for Zebra mussels too.
I've always had problems with unwellcome authoity figures I am the one
that every body used to suspect if some bigshot got fraged .
I just dont like glass sealings keeping good folks down while the

Hi Bruce,
I saw your post about your 90 gal tank and was curious
about your stocking density, filtration setup, etc.
for smaller tanks like this. I am new to aquaponics
but have messed with aquarium fish (mostly south american
cichlids) for years. I decided my first setup would be
small so I could make changes easily and learn in the process.
maybe later, I can use it as an educational tool.
I have several tanks and filters from the aquarium days
so I setup what I call my patio salad bar on the patio.
I made a stand and put my 55 gal aquarium on bottom.
Right above it is a bed I made from an old waterbed frame
(I love salvaging material) and lined with pond liner
material. It is 2'x4'x9". Originally this was going
to be a flood and drain hydro system but couldn't resist
getting started with aquaponics. I'm not worried about
production numbers right now
.just processes. I'm using
things I had around already like my magnum canister filters
and bio-wheels. I know I will have to clean the canister
filters alot
that's ok, they are setup to be easy. I'll
dump the canisters in a dewatering bed (just a trash can
with drain holes filled with gravel and sand). Then the
dewatered waste will go to my vermiculture bed.
I'm just finishing this and haven't stocked it yet. I was
thinking of trying hybrid bluegill
.maybe tilapia. The
gravel is going in the bed today and I have to setup the
irrigation grid. I'm not quite sure about the drip rate.
Any suggestions on this or the other things I mentioned
would be appreciated greatly.
I get this done and I'll play with my 90 gal in the basement.
I eventually want 200-300 gal system in the basement feeeding
growbeds on my patio. The temps are very consistant in the
basement and it would free up a lot of space for growing on
the patio.
have a great weekend,
Mark

Bruce,
It seems there would never be an end to questions in here about
application of species to aid in cleaning water or grow out for market
When I work at the Monterey Bay Aquarium every other weekend as a guide
and aquarist I find the more we learn about the ocean environment the less
we know as our knowledge increases. One alarming tid bit of info I heard
about 4 years ago which concerns all of us in here is
. within 20 years 80%
of our seafood (including fresh water species) will come from farms. This is
a green light to increase not only production but education, financing,
markets and in here shared knowledge. Everyone here has gone far beyond the
call of duty and to paraphrase a famous movie line, "We who are about to
fry, salute you".

great line, Arlos. I'm really starting to like this
place. This has been a fun thread for me. I had always
thought that if I ever returned to wastewater treatment,
it would be in this area. I left, not because I wanted to,
I love working with water
.always have
I left because
of some very serious circumstances with my employer that
contributed to the death of a friend. This place, and my new
hobby, make me feel like I have come home again. The knowledge,
experience and willingness to share here is incredible.
thanks everyone

The problem we are having in the northeast is that the zebra mussels clean
the lakes so well that the fry don't have food sources. The water in some
lakes is clear to thirty feet.
If the mussels are using the algae as a food source what about waste
production?
If you can find a way to harvest the mussels they would be a great source of
calcium for farming/gardening.

Mark,
I've gotten into more dirt kicking, hard hat throwing matches than I care
to remember over safety issues. I've never had a an OSHA reportable or even
recordable on my watch. I've shut down more work due to lack of excavation
benching and shoring, confined space entry and lack of chemical
characterization than most engineers will see in a career. Supervisors and
foreman now see jail time if they can't comply with safety. I hope you can
find a renewed place in water treatment. You're correct about this board.
There are some amazing folks in here. Hopefully in time the issues of
working with electrical in a wet environment, you can help by passing on
safety information about lock out and tag out protocol from your treatment
days to others in here. 110 VAC can kill just as quick as 480 VAC 3 phase.
To some, a piece of black electrical tape serves as a tag out device. I
still run across those that have never heard of an MSDS. I constantly find
those selling Ozone equipment know absolutely nothing about the gas itself
and tell customers it's perfectly safe.What many people have under their
kitchen cabinets is enough to make anyone in the HAZMAT field wake up at
night sweating
.Safety regs keep people happy, healthy and alive.

My understanding is that they will attach to anything from sticks to rocks.
They have a problem with one of the power plants where they can block the
cooling water intake pipes in a season.
If we can find a good way to harvest them maybe we can control their
population enough so that they will no longer be a threat.
What about having a separate pool/pond for the mussels and let the water
sift back through course sand. Would that prevent contamination of the
growing ponds with the mussels?

Kris,
Check out this website:

Mark since you like me have considerable Aquarium experience you have
most of the knowledge necessary to excel in aquaponics now all that you
need to do is take any kind of hydroponics system and attach it to your
Aquariums and you will be in business. I like the idea of the S-S
system it works but you can use any type of hydroponics system in series
and they all work .Try a raft system or a perlite floating bed with
good under bed aeration and you will see what I mean with say a mussel
bed in gravel under the raft in the same container. My fish seem to do
better with the mussels so now that Ted let the cat out of the bag yes
the fish do grow faster with a mussel bed in the system I'm just not
ready to say just how fast but that point alone could be all the
difference between just break even or good profits so consider it.
Consider removing the filter cage out of the Magnums and just using
them as pumps for now I have more to tell you but I have to go or my
wife is going to brain me.

Mike,
Though UV is relatively inexpensive to operate. the water must be
absolutely clean to function properly. Ozone is by far the better choice. If
you use UV, use a lamp rated at 254 nano meters. Its refered to as a TOC or
"Total Oxidizable Carbon" lamp. No life gets past it. It would especially be
applicable to anyone considering using zebra mussels as a method to insure
they never get out of the loop alive.
On a note of invasive Zebra Mussel control, there is a body of technology
known as pole magnetics and no not strapping magnets on a pipe but an RF
generator that has the net effect of converting calcite to aragonite. It may
cause the shell of the Zebra mussel to become thin and perhaps dissolve. If
Bruce happens to read this, There is an interesting character in his neck of
the woods by the name of Ed Ebert who owns a company called Eco Soft who
could fill him in on the possibility of this application. I use this as an
alternative to traditional softeners and in cooling towers to control
exopolysaccharides.
My wifes giving me those afternoon looks
