Abstract To analyze the intestinal microbiota diversity of several important economic fishes in the Loudi area and its correlation with the microbiota of water environment, the high-throughput sequencing based on the bacteria 16S rRNA was used to analyze the intestinal microbiota diversity in fish intestines and water. The results revealed that half of the OTUs in the water sample could be detected in the fish intestine, the proportion of shared OTUs in the intestines of Hypophthalmichthys molitrix and water samples was only 22%, and the unique OTU in the LC group was relatively the highest in the fish intestinal group. It can be seen from the analysis in NMDS analysis, the distance between Hypophthalmichthys molitrix group and water group is relatively farthest. Ctenopharyngodon idellus has the highest microbiota richness and diversity (P S can be considered in terms of microbiota richness. According to the Shannon index in Fig. 4, the diversity of the CC group was significantly higher than that of the other groups (P 0.05).

Fig. 3 Chao1 index. The Chao1 estimator estimates the number of species that actually exist in the community by counting the number of OTUs detected once and twice in the community. The different lowercase letters indicate the significant difference (P
