Thanks to Martin Hallmann I can add a very good article on the culture techniques of Moina as they were developed in Florida. Things work easier too, but the article goes into the fundamentals and is very informative. It was first written 1992, then revised in 2003 and newly reviewed 2011:

At the end they name two people of the University of Florida as sources for Moina: Scott Graves and Robert Leonard, Tropical Aquaculture Laboratory, 1408 14th ST SE, Ruskin, FL 33570, (813)671-5230.
The species mostly recommended is Moina macrocopa.
