Different types of fish have different favorite foods, and their intestinal microbiota composition is also different. The aim of this study is to compare the differences in the composition of intestinal microbiota in fish with different dietary habits, and to deeply understand its related mechanisms. By analyzing the intestinal contents of multiple fish species and using high-throughput sequencing technology, the intestinal microbiota composition of different categories of fish was analyzed to explore their corresponding metabolic and functional characteristics. The results showed that the fish gut microbiota was mainly composed of Proteobacteria, Firmicutes, Actinobacteria, Bacteroidetes, and other bacterial groups. However, the intestinal microbiota composition of different types of fish was significantly different. The dominant bacterial groups in the intestines of different fish species were significantly different, and the bacterial richness and diversity were also very different. This study provides a reference value for the ecological and functional research of intestinal microbiota in fish with different dietary habits.【Keywords】fish, intestinal microbiota, metabolism, differences
