I would like to try bui;ding some ouside trays a la Jim R. in the Virgin
Islands...Plastic readily available to me is 6 mil polyethylene.
Is this Ok. in your opinion?
Any experiences with durability in sun?

I saved about a year or so ago, mail concerning great liquid plastics
for waterproofing cement roofs and tanks. etc.
I would like to know a bit more about additives that I can mix in the
sauce for a ferrocement tank... any profs out there?
I asked this question and a friend got a reply from Jim Sealy. Im
wondering if it the same alias here on this list.If so, any tips, or
enlightenments???
AquaBlessings... Mike

i've had very good experience w/black hdpe (high density polyethylene)--but
make certain that the material is uv-treated

Adriana - I'll try to get to the USDA market pages to look at the current
pricing, but I'm certain it's fairly low. Parsley is one of those plants
that, I believe, falls into the "customer service" area.
In direct marketing to restaurants I think it's important to work on firming
up relationships, and any crop that helps to keep the buyer thinking of you
as the supplier rather than looking elsewhere for products you can provide
has a benefit. While parsley will probably never fall into the "profit
crop" status of basil, it's definitely viable in my opinion. Consider it a
value-added option you can offer your customers as they place their orders
for your other greens. Flat-leaf varieties are used fresh in various
dishes, while the triple curled is more popular as garnish.
Parsley can be grown densely (staggered planting similar to the square-foot
method) and still produce marketable growth once the plant is mature. Since
your harvest will be from the older outside growth, frequent harvesting
serves to keep the space required at a minimum, as well as eliminates most
insect problems. It's probably one of the few long-term crops that has
these benefits. Also, since it only needs replacing every-other year,
parsley is actually quite valuable as a system "stabilizer", providing
constant growth in your biofilter while allowing you flexibility with other
crop activities.
While we've found it easy to grow in our aquaponics system, it's long tap
root may be difficult for more shallow media systems. That probably the
only drawback I can see.
Hope this helps.
Paula

S & S Aqua Farm, Paula and others...
Could you kindly send me all your archived docs or spots of info on
tried and tested stocking levels, ratio/fish to growbed, aeration/fish
etc...
I have no two persons/ paces saying the same thing...
Thanks all, MIke

And you were hoping to find concensus here???? Sorry, just joking! ;)
I think you'll find that the various figures you've found will prove to be
accurate for the specific system or operation described, at least to the
best of the ability of the provider. Keep in mind that most aquaponics
systems are constantly evolving, being improved and updated as their various
side experiments progress. Many on this list have been working to perfect
just these items for many years.
I can pull some of the older correspondence from our files wherein different
folks have described their systems, ratios, etc. and the rationale behind
their decisions. You will find, however, that you won't have any fewer
results than you are currently evaluating, and perhaps more.
I will be happy to post our ratios and other information. You'll have to
keep in mind that this is what works for us in our location, the way we
manage the system, with our method of feeding, growing in our preferred (and
available media), with the fish we prefer and the water source available to
us; not to mention the climatic differences that might exist between our
location and yours.
The beauty of aquaponics is that it is a "general" description that fits a
lot of different operations, each perhaps successful in its own location.
To the benefit of each operation is the flexibility of the discipline to
make it workable in each of its many forms, as long as the "natural" aspect
of it is not pushed to extreme.
Why don't you give us some more details about your location, size of your
intended operation, market, fish preference, feed options, etc. Perhaps
then you'll be able to encourage more specific information that will be
useful to you there.

Was it this list that someone was looking for some taro a while ago? I just
spotted some for auction on ebay. It is listed under Miscellaneous: Garden
items: Plants/Seeds: General.

I live in Taro land. Find out what the shipping requirements/restrictions
are in you neighborhood and I'll try and find the variety you want and send
it to you (from Hawai) for cost. Contact me off the list. PS Excellent

Well this is mainly for Tom but info to all
I took 2 groups of 25 each 4-6 inch blue channel fingerlings and placed them
with Tilapia
Group 1
Placed in net pen in tank with cage going from floor to top of tank
Temperature 83- 86 degrees
fed every three hours same as Tilapia
Fecal matter from Tilapia allowed to enter cage
after 2 weeks no noticeable change
2 deaths
Group 2
Placed in tank with Tilapia no net cage - true poly culture
Temperature 83 - 86 degrees
Would like to say that the feed schedule was every three hours
But
After 6 hours Tilapia had killed all but 1 and it was caught and removed to
isolation tank - Died next morning
