Hi guys,
Here are fabulous phrases that you should keep in your files. Paula,
I'm whacking myself with a wet tilapia as I post this totally off-topic
note. Actually, the connection to aquaponics is that they validate the
reasons most of us left the corporate world behind to play with plants
and fish. Enjoy!
Adriana

Hi Mark,
I'm currently in Cordova but will be moving to the interier in mid
April. It may seem a bit strange to be researching a project like this
now but I'm convinced that this could work and if I'm right it could
have a profound impact on the economics of coastal Alaska. My objective
is just to make some connections between people that can make it
happen. I'm actually having to walk away from several interesting
projects here. I've been doing an accelerated community and
organization development project here and during the past two years I've
managed to built a highly functional tribal organization with a
democratic workplace. Most of the staff who never used computers before
are now are managing programs. All of our business is conducted via
email which has proven highly effective
and I've been working toward hooking up all the tribal households to the
internet via the tribe's home page (under construction). All of my work
with participative democracy has proven effective and I have a lot of
interesting stuff going but I just burned out too soon. My point in
telling you all this is that I may be doing some consulting work for
these folks down the road and would love to follow up on this project.
If not, I'm happy to make the connections.
Regarding the Kodiak project, I don't have any first hand info. on it.
I do agree that bringing in additional fish waste from other canneries
is the most logical strategy. I'm not sure what the electric rate is
but I can say that it is very high. I'm going to forward this to the
City Manager of Cordova and see if I can get some answers to your
questions......pete

William, thanks for lead. I spent a couple hours reading stuff on the
site you sent. Has anyone else used any of this stuff? I would like to
hear more on it and get some opinions......pete

Tony, what you reported there was the standing crop biomass at a point in
time, but how long did it take for each of those plant types to acheive that
biomass (net biomass production per unit time = net productivity)?
Just curious.

Sam sending fish down to the lab is next
But I think I might have it solved , to my dismay
If any of you remember back in November I had a huge Aurea die off due to
two strains of bacteria. Well the gravel from the biofilter I though was
thrown in the garden , but DW told me she thought it was to be reused so
took it to the shed and dumped it in the bin where I store the extra.
Well I used all that 2 weeks ago topping up all my biofilters . So chances
are I infected all my fish . I was advised to destroy all the Aurea as even
if the recovered they would be carriers . So I will be sending fish out on
Monday to Kentucky State and wait for the bad news

I prepared a 10 point outline of organic aquaculture standards back in 1997
and submitted them to those who I thought would forward them to the USDA. I
appeared before a public hearing on the organic standards issue and my
standards were submitted to the Texas Organic Certification Program run by
the Texas Department of Agriculture. At the time, I also sent copys of
those standards to Tom and Paula Spearaneo and to Gordon Watkins for their
review. I till don't know if my contributions were considered , reviewed,
discussed or....lost in the void...by the powers that be...since I heard
nothing back from USDA or the NOSB folks.
The person who might know what happened to my aquaculture standards that
were supposedly to be sent up to the NOSB level might be Cissy Bowman at
Organic Farmers Marketing Association cvof@iquest.net or possibly Val Carr
at Indiana Certified Organic Vcarr92702

Pete
I did some work using fish silage and wood shavings and saw dust as a very
fast compost. In and out in 30 days and created in excess of 180 degrees in
the process. We Heated water with the heat created in the process. I don't
know what you would have for a carbon source, if no wood by products are
around.
Just some more thoughts
