简介
Gut microbiota and their metabolites are increasingly recognized for their crucial role in regulating the health and growth of the host. The mechanism by which the gut microbiome affects the growth rate of fish (Cyprinus carpio) in the rice-fish coculture system, however, remains unclear. In this study, the gut contents of the fast-growing and slow-growing (FG and SG) carp were collected from the rice-fish coculture system for both the fish gut microbiome and metabolome analyses. High throughput 16 S rRNA gene sequencing showed that the overall gut microbiota of FG group was distinct from that of SG group. For example, the cyanobacteria were highly enriched in the guts of SG carp (18.61%), in contrast, they only represented a minor fraction of gut microbiota for FG group (<0.20%). The liquid chromatography-mass spectrometry (LC-MS)-based metabolomics analysis revealed that 191 identified metabolites mostly …
