I use ongrown artemia a lot, not to adult size, but I basically do not feed instar 1 nauplii unless I have to given the size of the fry. Ongrown artemia has better nutritional value compared to instar 1 nauplii when fed properly. Protein content is higher and essential amino acids are higher too. Lipid content may vary dependent on the feeding, but it is quite easy to encapsulate with emulsified lipid concentrates if you are not sure. I do not run flow systems, just feed the nauplii with algae where the lipid content can be manipulated by cultivation methods.
