The effect of reduced Artemia and rotifer use facilitated by a new microdiet in the rearing of barramundi Lates calcarifer (BLOCH) larvae

We found that the best protocol for rearing barramundi larvae involves feeding enriched rotifers from initial exogenous feeding to 3 days after the initiation of stomach differentiation at 5 mm standard length (SL), and including supplemental levels of enriched Artemia from 5 mm, to post metamorphosis at 12 mm. Co-feeding barramundi larvae on microdiet (i.e. Gemma Micro) should start when the larvae reach 5 mm, in order to establish microdiet early and allow a more efficient weaning process.
