Impact of early-life rearing history on gut microbiome succession and performance of Nile tilapia.

ABSTRACT:

Background

Fish gut microbial colonisation starts during larval stage and plays an important role in host's growth and health. To what extent first colonisation could influence the gut microbiome succession and growth in later life remains unknown. In this study, Nile tilapia embryos were incubated in two different environments, a flow-through system (FTS) and a biofloc system (BFS); hatched larvae were subsequently cultured in the systems for 14 days of feeding (dof). Fish were then transferred to one common recirculating aquaculture system (RAS1, common garden, 15-62 dof), followed by a growth trial in another RAS (RAS2, growth trial, 63-105 dof). In RAS2, fish were fed with two types of diet, differing in non-starch polysaccharide content. Our aim was to test the effect of reari
