fairy shrimp culturing - with brine shrimp reference

[paris]

i have to establish some sort of on going method to produce Anostraca for an experiment i am doing. I have data on how to get production of cysts, and then use those to start a new culture but i am wondering if i can keep a culture going for -say 3 months, or even 2....do these guys HAVE to dry out to hatch? i know brine shrimp are similar in many ways-have people who have raised them before been able to get multiple generations from one batch of eggs? there is much data i can read through out there but it involves a drying process but I'd like to have these shrimp at many different stages to offer them up at any time instead of having multiple tanks of 'new batches'.

i'm kind of doing the same thing and i've learn they lay two types of eggs summer eggs and cysts
summer egg that hatch as soon as they are lay and cyst wait out the winter in mud, the cysts have to have a resting period, usually about 6-10 months. the adults from what i've read live about two months, but i haven't found out how to produce cyst, so how do you do that?

that is pretty easy, it just requires some keen watching-you isolate the females that are carrying the opaque pinkish (fertilized )eggs and let them drop them in another tank then pipette them off the bottom and put them in a coffee filter to dry. then some recommend putting them in the freezer for a while and others recommend drying them at 35 c. there are lots of papers on them-esp in aquaculture journals, but none mention the direct eggs that can bypass the cyst stage. there is at least ONE species of fairy shrimp that can produce both eggs and cysts-so 30% will hatch out right away. I dont even know what species is in my area of research (playa lakes in lubbock TX) - nor how long they live. but in order to get this proposal written I will need to have the culturing method laid down in ink....
