Hi all,
Some days ago somebody mentioned some plant in connection with natural insect
control. All I can remember about the post is that the fruit would burn with a
blue flame if lit, and I think the origin was somewhere in South America.
Could that person please repost, or somebody else give me the name of that
plant.

Hi all,
I was just given a 400W HPS light fixture (including ballast). I know that
HPS only gives off the majority of its light on the red end of the spectrum
(best for flowering), but I have read about Metal Halide bulbs that are
"conversion" bulbs. I don't think I'm mistaken on the fact that there IS a
conversion bulb out there, but now that I think about it, I'm thinking it
might be an HPS conversion bulb that fits into a MH fixture...
Can somebody please help clear this up????
Thanks lots!
Devon
P.s. I've been following the whole EC discussion, and although I can add
absolutely nothing to it, the discussion has be great...BUT, how exactly do
you smoke crawfish??? ;-)

Your second thought is correct. I have used HPS for the vegetative cycle
when one of my halides burnt out and it was 100 miles to the light store.
As long as there was a combination of halide and HPS, I didn't notice any
growth disparity during the vegetative cycle. HPS will add weight and
size to your fruit better than clear halides. Phosphorus coated halides
do a good all around job if you want to save money. The conversion bulb
you spoke of only used to come in a 940 watt size but I haven't bought
any for years.

'owdy Devon,
You're on the right track, there is a MH Retro lamp,
that'll work in HPS gear, and lately, a colour-corrected,
blue-enhanced HPS lamp, the Sunmaster range, still fresh
since a rep. was in on Wed and saw the graphs, which look
like they will be fine and dandy for the whole grow/bloom task.

Subject: The Value of Sludge
From: "TGTX"
Date: Thu, 19 Apr 2001 21:08:54 -0500
What do I say about sludge?
"Lively up your sludge, and don't be no drag."
John Reid has been bustin' all the records with aquaponics for years. In a
21,000 square foot "solar" and wood heated aquaponic system in Amherst,
Mass., that he has operated since 1986, which, by any measure of the word,
is economically successful, John produces anywhere from 500,000 to 1.2
million pound of tilapia per year, along side with high value basil, and
tomatoes. He reports that about 25% of the input nitrogen from the feed is
taken up by the fish and plants, while 70-75% of the nitrogen is physically
removed as sludge... Is this a problem?....well, it depends on how one looks
at a problem....do we react by whining about it, or by doing something
innovative and positive about it...is this any hill for a stepper? Is
Yankee ingenuity a myth? I challenge you! Is it?
Is this fish sludge a problem? Or is it a resource? Is it something to
"throw away"? If you take John Reid's example, you can place that sludge
from the 21,000 sq.ft fish farm and spray it on 100 acres of land for
conventional dirt crop production. All of you should take that ratio and
think about what you might be able to achieve in your back yard or in your
"back forty".
What about algal systems in context with this nutrient source that we have
in aquaponics? Can you appreciate the fact that algal culture systems have
been shown to grow at sustainable levels of 6 to 12 grams of carbon per
square meter per day, which is about 200 to 400 wet tons per acre per year,
with peak production levels of 40 grams per square meter per day? The
problem with such systems has been associated with harvesting and processing
this phenomenal algal mass, which can produce, depending on the species of
algae and growth conditions, 40 to 50% protein dry weight yields. What if
you just harvested that algal biomass and kept spraying it onto your outdoor
garden? Believe me, I can tell you that a steady stream of high protein
algal biomass sprayed onto a raised bed outdoor garden will result in a
phenomenal resource for your homestead food production system. This is
awesome.
I will offer this info on my website when I get it up and running.
Did you know that if 50% of the nitrogen from one acre of conventional
catfish production ponds were to be incorporated into aquaponically grown
lettuce biomass, that the lettuce production would amount to about 50,000lbs
of wet biomass on about a 2 to 3 acre growing area? And did you know that
if all you were able to achieve was 0.25 lbs per square foot of lettuce per
crop, but you were able to sell it for only $3.50 a pound as gourmet
lettuce...that you would have a big honkin bunch of cash flow if only you
could work it all out??? Well, it has been done, to one degree or another,
at some scale or another. It aint impossible, folks, but it aint easy
either.....and even if it violates some pre-disposed notion of electrical
conductivity requirements, then we can still shake our heads in disbelief
all the way to the bank.
Another promising approach is is use various filter feeding organsims and
attached algae grazing organisms to convert all that nutrient abundance into
a desirable and readily harvested animal protein source. Filter feeding
bivalves are one possibility, but then we have the herbivorous
fishbait fish.....Tilapia....etc...
Sludge is Gold....
Ca-Peach?
Amen?

From: Myra D Colgate
Hello,
Space is still available for anyone who wishes to attend this course.
It could benefit marine as well as inland fish farming operations. Here
is an agenda of the course:
*Tuesday, 9 a.m.-12--Welcome, overview of by-products, fish soluble
nutrients as an organic plant fertilizer, ensilage of fish processing
waste for animal feed.
**Tuesday, 1:30-4:30--Hydrolysates for agriculture and aquaculture use,
higher value products for medicinal and industrial use, biogas production
from anaerobic digestion of processing waste.
***Optional, informal evening problem-solving session.
*Wednesday, 9 a.m.-12--Methane production to supply energy needs: project
results of fish manure digestion, digester construction, operation and
cleaning up of gas.
**Wednesday, 1:30-4:30--Efficient uses of methane, utilizing the valuable
by-products of anaerobic digestion, putting methanotropic bacteria to
work.
***Optional, informal evening problem-solving session.
*Thursday, 9 a.m.-12--Turning waste into valuable compost: principles,
methods and uses.
**Thursday, 1:30-4:30--The benefits and methods of vermicomposting,
producing Tubifex worms for larval and tropical fish diets, accessing
technical resources, finding your market niche, and wrap-up.
*Friday, 9 a.m.-noon--field trip to selected sites of interest.
Specialists with various expertise have been selected and the classes
will be informal allowing plenty of time for questions and personal
attention. Friday morning is set aside for a trip to selected field
sites of aquacultural interest located in this area. Participants are
also asked to bring photographs and/or slides of their operations,
representations of solutions to problems that they have come up with, or
problem areas they would like to have help in solving, too. Photos are
worth thousands of words.
Course instructors will be: Dr. George Flick, Extension food scientist,
Dept. of Food Science and Tech., VA Tech, Blacksburg, VA; Dr. Joe
Fontenot, professor of animal science, Dept. of Animal & Poultry
Sciences, VA Tech., Blacksburg, VA; David Causey, senior engineer, Duke
Engineering & Services, Charlotte, NC; Dr. Helene Hilger, asst.
professor, Dept. of Civil Engineering, UNC-Charlotte, Charlotte, NC;
Regina Guyer, grad. student in civil engineering, UNC-Charlotte,
Charlotte, NC; and Charles Johnson, Aquaculture International, Inc.,
organizer/facilitator, involved with aquaculture education and extension
since 1971.
The Asheville, NC, airport is a one-hour drive, or the Atlanta, GA
airport and also the Charlotte, NC, airport, are both 2-1/2 hour drives,
any of which would be the best airports to utilize for reaching this
area--dependent on the airline carrier you have chosen.
For accommodations, there are fully-equipped log cabins as well as
modern rooms or condos for larger groups, located in the Nantahala
Village. The number is: 1-800-438-1507. Nantahala Village e-mail is:
nvinfo 'at' nvnc.com, or visit their website: www.nvnc.com.
If you wish to come, and the Village is too high in price--it is the
beginning of the tourist season--there are much more reasonable places to
stay. Call the Chamber of Commerce, Bryson City number at
1-828-488-3681. There are many camping places in the Gorge and there are
more motel accomodations in Bryson City or in Cherokee.
To register for the course, send your name, address, name of farm or
agency, phone, FAX number, and e-mail address, along with a check or
money order to the USA address: Aquaculture International, Inc., P.O.
Box 606, Andrews, NC 28901, telephone/FAX: 1-828-479-6294. E-mail:
mldcol 'at' juno. com with any other questions or to give a mailing address to
request course or area brochures.
The cost for the course will be $125 for the three-and-a-half days of

Hi Emmett,
I'm really upbeat and I'm really downbeat.
I'm upbeat because we finished putting up my greenhouse today and I finished
putting together my "Earthboxes". I will be putting some tomato seedlings in
them tomorrow. We'll see. It is very nice. Looks really cool.
I'm downbeat because the same old damned problems keep plagueing me with
these fish.I'm starting to think that I have stunted fish due to the
problems associated with my own learning curve. These Tilapia have gone
through cold water, very high nitrate/nitrite levels, DO of sometimes less
than 2 ppm. These poor guys are survivors of someone who didn't have a clue
what he was doing 17 months ago. (Remember these fish are 15 - 17 months old
and still only weigh +/- 3/4 lb.)
I have received some less than favorable feedback concerning my opinion of
Sipe's fish.Many of his clients have had very, very successful results. My
results have been terrible. Maybe it is because of my own poor husbandry.
Who knows??!!
Just kind of bummed right now.
Steve
