Re: [Killietalk] Daphnia questions..

["Markus Brown" <thefishbiologist at charter_net>]

Joseph;

Once they have been introduced, there is no way to separate them. The only 
way to keep them out of your culture, is to keep your Green water culture 
sterile from other pollutants and not exposed to any "wild" introductions. I 
tried to use the green water that I have been getting from an outside tub. 
The culture tended to crash rapidly because the copepods out competes with 
the daphnia or moina I was culturing.

My intention is to start a new culture of pure green water (one consisting 
of only one species of algae) and to culture the moina and daphnia in 
covered containers. My most recent success with Moina was ended by what I 
think was a nutritional deficiency and the culture ceased to function. I am 
going to supplement the green water with a rotifer enrichment of one kind or 
another. (probably Roto-Rich) Moina cannot survive alone on one food source 
unless it is a mixture of ingreadiance. I ran out of green water and the 
yeast I was feeding just wasn't enough.

Oh well. Live and learn!

Markus
