You may be right George.  This is the first time that I've tried this.
I don't expect a crash from simply having the shrimp in the green water,
though.  I have the tank illuminated 24 hours a day so there should be
no decline in dissolved oxygen at night.  The culture is also aerated
with a rigid airline.  What I am seeing, is that the culture is clearing
more rapidly than I expected.  The shrimp are half grown now, and, so
too young to harvest.  I have a powdered brine shrimp feed on hand in
case the culture goes totally clear. 

I've had multiple indoor daphnia cultures going for almost two years
now.  I start them in slightly green water with some sort of other food
added (crushed tetra bits, vegetable baby food, Kent Micro-Vert).  The
species that I have now (D. pulex?) is very crash resistant. I have
tried more sensitive types using the same culture technique and seen
crashes.

I'll let everyone know how things progress and what kind of yield I get.
I'm thinking that if the culture becomes stable I should be able to pull
enough shrimp out to feed two or three tanks once a week.  Not what the
average killie keeper would call worth wile, but I kind of like the
shrimp so If it works this culture won't be wasted space.

Cheers,
Chris
