I can't many culture? At small scales? Tired and overworked?
So your saying herpacs are not real copepods? Do they know this?
Understood that not many will eat the hairy herpacs, but the system I use to grow them, was bastardized from a calanoid set-up, with a few modifications (screen sizes/vertical walls of window screen/feed)
Do you not distpute that certain algaes have shown to inhibit growth, even act as a prophylactic?
