I have been doing the live food culture room at my college. We have Nannochloropsis, Artemia, and Rotifers. The brine shrimp we have is the San Francisco Bay brand Hatch Mix. I have done 3 different culture starts and it still has about ten bbs hatching each time. Has anyone worked with this brand or with hatching bbs? Also if you have what did you enrich them with? I have been feeding them the Nannochloropsis I have been culturing, have you used Selco, or anything else? If any one has any advice that would be great!
