To explore the gut microbial profile of blunt snout bream (Megalobrama amblycephala), fish were fed with a commercial diet for 16 weeks. Then high-throughput sequencing was applied to compare the microbiota between foregut and hindgut. The results showed that the microbial profiles between the foregut and hindgut were different based on the alpha-diversity and the cluster results. Dominant microbioorganisms of blunt snout bream at genus level were Cetobacterium spp., Lactococcus spp., CK-1C4-19, Rhodobacter spp. and Pseudomonas spp. Meanwhile it was found out that Lactococcus spp. preferred the foregut, while Cetobacterium spp. and Flavobacterium spp. preferred the hindgut. Dominant bacteria preferred different gut section may decided by its function and physiological characteristics.
