To culture asian seabass / barramundi (Lates calcarifer) larvae, we are using rotifers as live feed, needing to be enriched with essential fatty acids (DHA and EPA):

1- Feeding rotifers with microalgae like Chlorella and enrich themby fish oil as DHA source before being fed to fish larvae.

2- Feeding rotifers with DHA and EPA rich microalgae such as Isochrysis galbana and Nannochloropsis oculata (no additional enrichment is needed).

Which one do you recommend and why?

Thank you
