Re: Moina (was LFD V2 #440
The people in Hawaii have been working with this crustacena quite
intensively and have gotten it identified to Moina micrura. Apparently, in
previous experiments Dr. T and Co have been able to get the cultures to
double in density every 24 hours. Nice as you can harvest half the culture
and have the same ammount every day. It don't quite work for me as the
cool conditions outside are slowing them down. Also there has been a lot
of work by Dr. Tamaru regarding the, sizes, fatty acid profiles, etc.
Aske me about the culture off list.
