Maybe you can help deter thievery by adding a few Pacu (Colossoma sp.) to
your ponds and then spreading the word that they're actually pirahna, which
they closely resemble and are in fact related to. They grow fast (much
faster than tilapia) and are really tasty. Sort of like putting those "theft
deterrant activated" stickers on your car whether you really have one or
not.
I've not tried soy beans although they certainly have good potential as
a fish meal substitute. Studies indicate that supplementation of soy-based
diets with calcium phosphate and/or methionine significantly improves
tilapia growth. . Also, raw soybeans contain a trypsin inhibitor which ,
"...can cause a problem when soybean meal is used at high levels in fish
feed." Boiling or otherwise heating the meal will eliminate the problem.

Possible basic ingredients for fish rations are flax,
hemp and sunflower seeds. These are principal components of
a product we make for humans that aims to deliver a
recommended daily intake of essential fatty acids,
primarily Omega 3 (alpha linolenic acid, ALA) and
secondarily Omega 6 (linolenic acid, LA). Requirements
of these EFA's are known for commercial freshwater and
marine fish species.
Of interest to aquaponics are freshwater species
such as:
Trout-type: Rainbow trout (Oncorhynchus mykiss)
that require 1.0% dry diet ALA
and
Tilapia-type: (Tilapia zilli and T. nilotica)
that require 1.0% dry diet LA.
Flax seed would probably be the best choice because
1) it's cheap and readily avalable, 2) stores well,
3) has the highest Omega 3 content, 4) easily ground
(in a coffee mill) and 5) when ground to nibbling size
for fish, it floats first then sinks slowly and does
not leave any oily slick on water surface. (Flax seed
has a mucilage coating; if the coating is not removed
or the seed ground it goes straight through fish or
human gastrointestinal tracts. Yet when ground provides
good fiber which fish usually don't get in their diet).
Hemp seed is not readily available in the U.S.; sunflower
seed has no Omega 3 but good amounts of Omega 6 and
Vitamin E.
Studies have been done and reported in "Flaxseed in
Arctic Char and Rainbow Trout Nutrition", Flaxseed
in Human Nutrition, Cunnane S. Thompson I. ed,
AOCS Press, Champaign, IL, 1997. It should be noted
that those studies sought to determine if flax
seed would influence fish rate of growth. Sometimes
it did. More important to aquaculture, though, would
be to determine if flax seed could increase the amount of
Omega 3 gleaned from this feed ingredient, then stored
in fish muscle to be passed along to humans.
In the wild, cold water fish species get their
Omega 3 from phytoplankton. Warm water species,
like Tilapia, get Omega 6. In other words, the
EFA's are gathred from plant sources, not manufactured
by fish.
Theory is that if both Trout and Tilapia raised
in aquaculture had a good source (more concentrated
than in what's in phytoplankton) of Omega 3 and
Omega 6 in their feed, say from flax seed, they
would store much more of these EFA's in their flesh
to pass along to consumers. (Maybe Tilapia, as do Trout,
might store the prized Omega 3 as well as Omega 6).
Wouldn't that be something!

Hello,
I read an interesting article where a fellow used a common area sensor, the
type used to turn your porch light on when someone comes close, and connected
it to a sprinkler valve instead. Whenever rabbits would come close to his
garden the rain bird type sprinkler would come on and hose them off.
On a more permanent fix: Miracle-Gro sells a brass attachment for your hose
that allows you to draw concentated fertilizer from a bucket while your
watering.
Suppose a person used concentrated colored dye instead, along with the setup
above. What fun it would be to go to town and see the RED faces Blue would
work good too. :}

Hello again,
This stuff scares me too. Last year in California 200,011 tons of pesticides
were put on
commecial crops alone. 80% to 90% of the pesticide has been shown to migrate
off of the fields and so some must be getting into the local communities air
and water supply.
Transgenic plants that express BT analogues could eliminate this entirerly.
How many kids living near these fields might never have asthma, bronchitis
or lung cancer if this were done. I wonder.
Kevin
