propagating phytoplankton

[Richard_Dicosimo]

i was wondering if anyone in calgary is doing it? and if so how did u start your origonal batches? because as far as i have read on the net people buy petree dishes of cultures from www.florida-aqua-farms.com. now i was wondering since once you have your cultures going in motion, you just keep splitting them to keep the process going, so why are people buying the petree dishes when u could just buy a jug of dts phyto?? am i wrong? can u not culture phyto after it has been refrigerated? am curious because i want to start culturing phyto but am not sure where to get a batch i can breed?

Also anyone know where to get a batch of rotifers to breed?
