NFC: RE: Re: Recent SSA newsletter on planktons

Hi icmykoi at mindspring_com :)

Primarily I feed microalgae - FW Selenastrum, FW & SW Nano chloropus,
SW tetraselmis - fresh or salt depending on organism.  Torula yeast,
powdered flake food, commercial prepared foods like Rotirich, or our
plankton feed, shrimp meal supernate.  Which I fix by grinding shrimp
meal in a blender, then blending in water, then run through a sieve,
then feed the water that comes off the sieving which looks like a
highly milked tea....

Small particulate matter :)  If it passes through a 53 micron filter
it is a good size to feed planktons, and daphnia in particular (yeast,
microalgae, rotirich, our plankton feed.)

I know there are other feeds.. cryopaste (I've never used, but have
heard of success with it.)
