Live Foods: Any experience with Daphnia eggs (ephippia)

Just found this link to buy Daphnia pulex "resting eggs" (ephippia) from Carolina Biological: http://www.carolina.... culture kit.do. Has anyone tried starting a daphnia culture this way? Has anyone managed to collect & store their own ephippia? I know they need some specific conditions to produce them instead of the instantly-hatching ones you normally get in a healthy culture.

Why isn't it more common to find these ephippia in the hobby? Sound like they should have most of the advantages of brine shrimp, *plus* be able to actually propagate the culture once you start it from eggs (possible, but hard with brine shrimp).

I tried to save some resting eggs from the Daphnia species in my pond. Wintered the eggs in the freezer. Zero luck re-starting the culture indoors.

I tried dry egg cultures just add water . I had them in container used my pond water got 3 daphinia to hatch out of batch of eggs which is horrible .

I started a daphnia culture once from frozen daphnia bought from the LFS.

I guess that would be sort of like a yogurt culture, eh?
