John, the challenge is the very small young are difficult to feed. Their young or larvae are planktonic and feed upon zooplankton, algae, and detritus. Often people refer to there food as "green water". You can culture green water and put large quantities of it into your indoor tank to feed the young grass shrimp. It's difficult to do in large quantities.
As jakeb said, I have decided to try to raise them in a small outdoor forage pond. The results of that should be known by summer time...
I still think as grass shrimp become more and more known to the pondmeister, they will be stocked more commonly. I feel when you stock your FHM, grass shrimp should also be stocked.
I have a lot more experience raising the brackish water species of grass shrimp and the Florida freshwater species than P. kadiakensis. However, they should be very similar as they both have a larval stage. But since I acquired P. kadiakensis last year I am hoping to get more experience with them as well as I think they are the species which is the best adapted to most ponds in the US.
