Hi All,
I have been using green water culture to feed the rotifers. I got
a starter from one of my sea grant friends at the U. Basically if you have
an unlimited source of greenwater (I now have two 100 gallon and one 50
gallon rubermaid stock tanks) to replace 50% of the culture tanks volume
per day. Found that gold fish and OSI spirulina flakes work really well to
make the water green. Right now I have gotten the culture up to the point
that it will clear the water every day, eventhough I harvest 50% of the
volume. Keep watching the TFH. My friends were asked to do an article. I
will be putting up some photos on a web site soon. This system works well
for boths moina and rotifers. I have been using Brachionus calyciflorus
(I think). They can be enriched as easy or easyer than artemia. They are
waht they eat and they will eat spirulina, asththaxin, etc. Harvesting is
not too much of a problems as I can use a brine shrimp net to collect them.
However a 40-60 micron screen works better.
I will try and get the photos up on a web site.
