Spray stuff contains some "potentially hazardous" chemicals..,...
My recommendation as a SCUBA diver is to get a pool patch kit. It has
plastic membrane and some adhesive - sticks fast and is
very permanent (ask my buddy whose pool was half empty even after a rain
storm). Works great.
As far as adhesives for tubing in trays, etc... Contact your local plumbing
store. Get some RTV silicone. It is very convenient if
you can get the stuff in the "aerosol" style can - no caulking gun required!

Forwarding this to the list in case any of you are interested in pursuing.

I just had to get in on this one!
I too can testify to the itch releiving qualities of this plant. I was
fortunate to spend a few years in the Appalachians, and took note of the
jewel-like yellow/orange flowers of this plant. As my wife and I would move
in for a closer look, we would always jump back from a brush-up againt a
stinging nettle. It didn't take long to realize that the stinging nettle
and the jewelweed plant grew as companion plants there in the wild (Mother
Nature's design). Now when I hike there and brush a stinging nettle, I know
a jewelweed will be found in the vicinity. To use the jewelweed, just crush
up some of the leaves and stems and rub the juices over the sting. Only
seconds later, the itch subsides.
I guess my wife "bonded" even more with this plant than I did. Her business
name is actually "Jewelweed". She's a custom jeweler and thinks the
business name sounds like Elmer Fudd saying Jewelry.
Unfortunately, not many locals are familiar with this plant and she get many
confused looks.
If anyone can supply me with a few extra seeds from the wild, I'll see how
they grow here on the rock (St. Croix).
Respects again,
Charlie

Mike,
This past Spring I presented some of our research at the 2nd Annual
Conference of Medicinal Herbs in the Caribbean. I included some of our
proposed work for this winter looking at the tropical culture potential of
medicinal herbs. The importance of testing levels of medicinal constituents
was addressed. Many herbalists prefer to use only wild-harvested plants
(not sustainable), and believed that medicinal crops grown in a controlled
environment could not possibly have the POTENT qualities of their
traditionally wild-harvested crops. So, I agree these crops should be
analyzed for nutrition/medicinal make-up after we culture them
aquaponically.
Does anyone know of a lab providing these services. Plants we will be
looking at may include:
Borago officinalis
Calendula officinalis
Symphytum sp.
Tanacetum parthenium
Valeriana officinalis
Echinacea purpurea
Hypercium perforatum
Sorry Mike, I haven't any references to your request.
Respect,
Charlie

To address the issue above I refer to a recent article in the Sep/Oct 1999
issue of Aquaculture magazine, "The Status of Aquaponics, Part 2" by James
Rackosy of the Univ of the Virgin Islands. He correctly asserts that the
amount of fish feed used is the driving force in determining the proper
ratio of aquaculture and hydroponics. Fish feed is the major source of
ammonia in the system and its daily use is necessary in calculating
hydroponics area. Rackosy offers this general rule for raft systems. Each
pound of fish feed per day can provide the nutrients necessary for 42 ft2
of raft hydroponics. A more general rule of thumb is in the UVI system 1
ft2 of tilapia tank provides nutrients for 11.5 ft 2 of lettuce
hydroponics. For a more thorough treatment of this issue see the Sep/Oct
issue of Aquaculture.
Another paper relating this issue was published in the Journal of
Production Agriculture, Vol 6, No 3, p 428-432,1993, "Yield of Tomato
Irrigated with Recirculating Aquaculture Water, by McMurtry, M. R.,
Sanders, D. C., Patteron, R. P., and Nash, A. This work looks at yield as a
function of biofilter size and stocking density. Briefly put the yield of
both fish and tomato increased as the tank to biofilter volume ratio
increased from 1:0.67 to 1:2.25. Biofilters were sand with Laura tomato
cultivar planted at 4 plants/sq yard. The conclusions of this experiment
were more detailed than those discussed above for lettuce but less
empirical. As can be expected as tank to biofilter ratio increased the
yield of both fish and tomato increased, indicating a better nutrient
balance thru the system. However, the systems were never heavily loaded
with fish and the yields of both fish and tomatoes were substantially less
than can be expected from commercial yield estimates. This illustrates the
difficulty in attempting to commercially integrate aquaculture and
hydroponics from an economic point of view. Neither the fish yield nor the
tomato yield can be increased to a profitable level when done in this
intregrated manner. Profit margins seem to be much greater when systems are
operated independently.Nonetheless the paper is quite useful in explaining
the dynamics of achieving a balance between aquaculture and hydroponic
systems.
To make a convoluted issue simpler gradually increase your plant mass as
your fingerlings grow. This is an easy solution to this complicated issue.

Hello Charlie! Please write me directly-I can't seem to get through to Jim.
Mike the Canadian govt has just enacted legislation to confirm constituents
and consistency. The industry uses private labs but I believe that the feds
are settting up a lab to confirm. There is a production company here in
Alberta called Prairie Naturals. Would it help if I found out how to reach
them and put them in touch with you?
Controlled crops have been proven for potency but of course it varies with
conditions in each area, so testing is done on an annual basis.

E-mail Peter at Aquasales.com. He is real good at finding anything you
need. I'm sure he knows (or can research) the best adhesive for the job.

Silicone might be an option for patching but you need to use the type
that is safe for fish. Aquatic Ecosystems would be the source.
