Actinomycetes are reported to give off flavor to fish. There's always plenty
of nitrogen in aquaponic systems. Jim R

Dave,
While on the surface your questions appear simple and direct, they are
really quite complex which probably accounts for the lack of response (that
and the holidays, burp).
Stocking densities will vary greatly depending on your system design and
really are more a matter of biomass than fish numbers. I've heard of densities
ranging from .25 to 2 lbs per gallon.
Likewise, crop densities will depend on several factors including fish
densities, biofilter surface area, and specific crops being grown. Tomatoes
require more nutrients than lettuce, for example, and so should be grown at
lower densities.
My own small system is designed with approximately a 1:1 tank to filter
volume ratio with 175 square feet of growing surface per 1,500 gallons of
water. University research indicates potential yields of approximately 55 kg
of fish per cubic meter of water per year and tomato yields of 10 kg per
square meter of growing bed per crop cycle, although I have yet to confirm
these figures.
If you could provide some details about your particular system I'm sure
more discussion would ensue.
Happy New Year to all,
Gordon Watkins
