Hi Paula!
I never meant for this to be so alarming. I'm sorry

They look like microscopic "worms" and attack many types of problem
insects (fleas, thrips, fungus
gnats, etc.). They are unrelated to pest nematodes and do not attack
plants.
I would think they can be used in an aquaponic system without harm to
the fish, but my experience was in hydroponics. Has anyone out there
tried this in aquaponics?
I have successfully used a product called Gnatrol (Bt israelensis) a
liquid formulation of Bt from Abbott Labs similar to VectorBac that is
also highly selective against the larvae of greenhouse fungus gnats. The
liquid is diluted with water and sprayed onto breeding areas where it is
fed upon by the larvae, causing death within 24 hours. This is a
larvacide only and will not kill adults, so timing is important. Gnatrol
can be injected in greenhouse watering systems, but should not be mixed
with fertilizers or fungicides containg copper or chlorine as this may
neutralize the active ingredients. 1-2 tsp per gallon. 16 oz. $13.95 1
gallon $39.95. This can be purchased from IFM in Wenatchee, Washington
800-332-3179. I use this company as a source for many of the biologicals
and products to help me grow greens and herbs hydroponically and
organically. Good people.

Friends - saw this post on the biodynamics mail group. I know several of
our members are working toward self-sufficiency and water conservation, and
perhaps considering captured rainwater as their water source for aquaponics.
Any comments? Paula

In St. Croix we use nothing but rainwater for our hydroponic systems. We
have a 20,000 ft2 membrane catchment on a hillside (3 degree slope)
overlooking our facility, 7,000 ft2 of greenhouse roof, and 5000 ft2 of a
building roof, all of which feed water to three interconnected water storgae
tanks (22,000 gallons each). Groundwater on small islands is generally too
high in NaCl for aquaponics. In our location there is no air pollution to
worry about but that could be an issue in the midwest and northeast regions
of the U.S. where rainfall deposition of elements and organic compounds is a
serious concern. Water collected from roofs should have potable grade
coverings. Jim R.

Donald - no need to apologize. This list was designed for the open
discussion of subjects relating to aquaponics. Events/subjects concerning
marine animals certainly apply here. I had seen the notice on whales on the
sustainable agriculture mail group, and thought it might well be of interest
also to our members who (we hope) will be concerned with sustainable
practices in their systems, with interest also in world ecological matters.
BTW - I can hardly say that my post of joy on growing my first strawberry
would technically fall under the subject matter, other than to cover the
fact that the nutrients appeared to be appropriate for this particular crop.
What we had hoped for when we started this mail group was to determine the
actual interest level of aquaponics. If we had intended only to have a
group discussion by those practicing aquaponics, we would have created a
closed list to discuss day-to-day problems and concerns.
What is amazing to me is that in addition to those who are using aquaponics
for their various operations; those who have products, services or
information available; and those just starting in their systems; there are
many members of this mail group who are only in the "investigating" stage.
And we have not had the questions/input from them that I had anticipated.
When we started, had we had this type of information/experience/knowledge
available through the internet, how much simpler our search would have been!
If this reads as an encouragement to our "lurkers" to make themselves known
- it is. I won't detail the amount of expertise available to you; but I'm
certain if you have specific questions, you will find willing participants
in most any discussion regarding aquaponics practices.
All introductions/questions welcomed! Hope to hear from many of you this week.

Hi Paula!
I was the one that posted it on the SANET and have had volunteers Emailing
protests to the State legeslature of Hawaii form all over the world and
many from this list as well. but the thread ends here. If any "lurkers" are
interested in more info on this subject Email Darby Davis at
awarenessmag@earthlink.net or visit their website at www.awarenessmag.com.
For me, its back to swimmers and weeds.
