questions on raising fish

[Maelle Cargou=EBt]

I'm Ph D student and I'm working on the effects of endocrine 
modulators present in river waters on zebrafish (production of 
vitellogenin). I'm going to expose the eggs to this water under flow-
through conditions until the fish are 3 month old. Between 0 et 30 
days, I would like to put 100 fertilised eggs in a 4L vessel. Then, I 
would like to put 50 juvenile fish to a 10L vessel until 3 months. Do 
you think this conditions are satisfactory in term of population 
density?  

Thank you for your attention.
Sincerely,
