Jan suggests:
In the 1980s, Steven Threlkeld, a limnologist at the University of Oklahoma,
did a series of ecosystem-level experiments in macrocosms: large, circular,
above-ground tanks. Among the questions studied was the effect of shad on
plankton communities. You might do a literature search, read his
articles, and see what his stocking (and recovery) rates were. His tanks
were not filtered or circulated, so you could apply some sort of
multiplicative factor for your own set-ups. Sorry, I do not have the
references at hand.
