Marc - try the following web site for a nice little publication on production of fathead minnows. It doesn't answer all of your specific questions, but has good general biological information on fathead minnow culture.
http://www.govdocs.aquake.org/cgi/reprint/2003/617/6170030.pdf Now, here's another way to get to that publication, and also see what else the Southern Regional Aquaculture Center has on baitfish production. First, click on the following link.
http://www.msstate.edu/dept/srac/fslist.htm Then, click on "BAIT FISH" and that will take you to a list of nine publications from which to choose. "Forage Species: Production Techniques" seems to have the most useful information.
