Hi Paula!
I just can't tell you how valuable this list is to my sanity. This is a
call out to all of the rest of you innovators.
Does anyone else have full tank diasaters on experimental work that looked
really promising?
I just had a 1,200 gal tank of Pacific Calico Bass go south on me in one
evening. I didn't consider the nitrate load might become too much for my
macro algae scrubber to handle and now I have a tank full of dead fry...
OUCH
Paula, our operation is like no other that we know of in the US. We are
privately funded and work on the illusion that poverty is cool. We have
propogated several species of semi endangered Pacific Ocean invertabrates/
shellfish. Our primary focus is on the cultivation of assorted marine macro
algae inorder to determine if salinity can be gradually reduced by
cultivated marine, brackish and salt tolerant vegetation that has food
value. We can find fish and inverts that will thrive under all of these
conditions if we can stabilize the matrix. Our goal is something profound
and invaluable to the fresh water starved.
Send me some info on yur program and I'll Privmail you our mission
statement and our pubdata for you to share with the rest of the list if you
feel that it worth sharing.
Living on Crumbs...

The Freshwater Institute at Shepherdstown, West Virginia has a series of
publications about producing trout in recirculating systems. They also
worked in coordination with a USDA laboratory in studing the use of
effluent and wastes from the system for producing different types of
useabel crops. I am sure that they would provide you with copies of
their publications if requested.

I wanted to introduce myself to the list. My name is Jeff Schahczenski
from real cold Montana. I have just finished building our families
strawbale house and am planning a greenhouse construction (probably on
on an earthship design(pounded tires)) and am thinking about aquaponic
growing. One of my biggest concerns is maintaining water temperature.
The other is the desire (value?) to keep the operation certifiablly
organic (ie organic hydroponics). It seems to keep an aquaponic
operation truly organic one would have to find a feed source for the
fish that was also organic. I have caught earlier postings on organic
feed, but am wondering whether anyone knows of feed mixes from organic
grains or legumes(lentils,peas)? From previous work I have good contacts
with quite a few organic wheat, pea and lentil growers in Montana.

In response:
I have not seen any specific information on raising bluegill or crappie in
recalculation aquaculture or aquaponic systems. I have seen a lot of
information on raising perch in recalculating aquaculture systems from the
University of Wisconsin -- Madison campus. There are several perch
aquaculture farms running in Wisconsin. People are willing to pay high
premiums for perch due in part to the quality of the product and due to the
memory of the many past perch fish fries.
I believe that perch require higher quality water conditions than do
bluegill and crappie. All of these require much higher water quality
conditions than do tilapia. I do not have any phone numbers or addresses
to contact. Good luck.

From: Rebecca Nelson

Hi all,
On Feb 28-March 1 we are sponsoring DISCOVER Aquaponics, a 2-day
workshop on aquaponics taught by Gordon Creaser, an industry consultant
with over 40 years experience. The workshop will take place in
Mariposa, CA, with morning sessions held at our classroom and hands-on
afternoon sessions at our greenhouse facility.
This workshop is designed to help you understand and apply the
principles of aquaponics, aquaculture and hydroponics. If you are
interested in these fascinating technologies, in becoming a commercial
grower, a hobbyist or are an educator who wants to use aquaponics in the
classroom, DISCOVER Aquaponics is an excellent way to jump-start your
learning.
If you would like more information, you can find it at our website at:
http://aquaponics.com/discover.html
or call me at 209/742-6869
Sincerely,
Rebecca Nelson

I haven't grown trout but know that they need very clean moving water at =
68
F or below. Both of these requirements are due to high oxygen needs (so
could possibly have slightly warmer or dirtier water with intense
oxygenation, since DO drops as temp or organic content rises). Since they=
are voracious (meat-eating) their food would be high-protein, so
over-feeding would need to be carefully avoided to maintain highest water=
quality. =

Paula et al,
In circulating water systems, how far below the surface of the
gravel/perlite is the water level kept (how much gravel above the water
level), and what is the total depth of the gravel?
Thanks,
Jack Rowe

If you are in the USA, generally your county cooperative extension service can
help you. These are standard items stocked in farm ponds. They are listed
under county government in the phone book.

Brook trout require quite cool water and have the highest oxygen requirements
of trout, so far as I know. Nonetheless, they are native in the USA at least
as far south as Georgia, and I've caught them there.
Rainbow trout are not as demanding, have gill rakers so that they can ingest
some algae as well as animal food, and generally make it in waters slightly
less ideal than a brook trout stream, though they live there well too.
Brown trout are, for a trout at least, fairly tolerant of warmer, less clear
water. They are generally used in marginal conditions as they seem most
likely to make it.
I've no experience with the sorts of trout growing in the Rockies and I don't
know much about lake trout. If I recall correctly, Bill MacLarney covers the
requirements of commonly cultivated trout species in his Freshwater
Aquaculture book.

A great idea. Hopefully someone will take some extensive notes and pass them
on to those of us who will be unable to attend.
