Could someone advise that would worm provides a complete meal to Tilapia.
That is does worm
contain the sufficient protein and minerals that are essential for healthly
fish and plants in the
aquaponics system.
I am actually thinking of setting up a vermiculture composting worm system
to feed my tilapia and
and also to obtain the worm casting tea for the aquaponics system. Does
anyone have such
experience before?
Thanks and Regards,
CN Tan

Dave--
Is this a preventive measure for macro-algae, micro-algae or both?
I can see shading preventing the sprouting of macro-algae--or is some
other mechanism at work here?

I've used worms in trials with largemouth bass with fair success.
But.. considering the worms are worth more per pound than tilapia,
you're better off selling the worms and buying feed. That is, unless
you just want to do it for the fun of it.

Here's another chapter in the Hybrid bream (sunfish, Lepomis. sp.)
discussion.
12 different combinations of crosses between various Lepomis species were
made. Only 1 produced young with a near normal sex ratio. That was A female
redear sunfish and a male green sunfish. The following crosses produced F1
generations highly skewed toward males:
1) Male (m) Green sunfish (GS) x Female (f) pumpkinseed (Lepomis gibbosus,
PS)
2) f GS x m PS
3) m GS x f bluegill (BG)
4) f GS x m BG
5) m GS x f longear sunfish ( Lepomis megalotus, LS)
6) f GS x m LS
7) f GS x m redear sunfish (RS)
8) m BG x f RS
9) f BG x m RS
10 m BG x f PS
11 f BG x m PS.
Many of these hybrids are of low fertility, if not sterile, rendering them
even more suitable for intensive culture. Not only are such fish readily
trained to take artificial feeds but they are highly valued due to being
thought of by many as the finest food fishes among the Centrarchidae (which
include the black bass, crappie, etc.)

I am starting my raised beds for lettuce and plan on using 1" in 4' fall for
drainage. Will this work with a gravel growing beds 12" high.
Is this enough fall. (I'm using 110 gallons for fish.)
(hello b-evens )
Many thanks
Craig

Hello Jim
Look forward to hearing about your new project.
I have a question about the feed. Who is the contact person and will they
ship to CA.
Keep on planting - Thanks
Craig

The article does not give enough details which algae but I have written
to them (OG) for the British sources cited.
I also recommended that they contact Paula to do an article on
aquaponics and to contact Ted concerning "organic feed" so keep the
fingers crossed.

I decide that the worms were too valubale to feed my tilapia and that they
were very labour intensive .They are free and keep the floor of my
greenhouse and fishouse clean. Their castings also are worth their weight in
gold.VPage
