Abstract

To understand how a bacteria-free fish gut ecosystem develops microbiota as the fish ages, we performed a 1-year study on the gut microbiota of hatchling gibel carp (Carassius auratus gibelio). Our results indicate that the gut microbial diversity increases significantly as the fish develop. The gut microbial community composition showed significant shifts corresponding to host age and appeared to shift at two time points despite consistent diet and environmental conditions, suggesting that some features of the gut microbial community may be determined by the host’s development. Dietary and environmental changes also seem to cause significant shifts in the fish gut microbial community. This study revealed that the gut microbiota of gibel carp assemble into distinct communities at different times during the host’s development and that this process is less affected by the surrounding environment than by the host diet and development. Community phylogenetic analyses based on the net relatedness index further showed that environmental filtering (host selection) deterministically governs the gut microbial community composition. More importantly, the influence of host-associated deterministic filtering tends to weaken significantly over the course of the host’s development. However, further studies are needed to assess whether this host development-dependent shift in gut microbiota will still exist under different rearing strategies.
