I gleaned some things from the paper that could be used in tank culture. Read the part about fertilization and brush for adding substrate. I would personally use organic fertilization (alfalfa or cottonseed meal). Remove to the brush to harvest. They produced 1000 lbs of them to the acre with bluegill eating them along the way. I bet you could produce a fair number of them even if it weren't optimal.
BUMP.
I wouldn't filter the water, that will remove food they will eat. At high density you may need aeration but they produced 1000 lbs/acre of them without it.
I cannot imagine how many PK it would take to add up to 1,000 lbs
That said, maybe I should look in to getting some in my BOW. I have chara and need to more efficiently feed my CNBG so they can in turn feed my LMB!
