Summary: The gut microbiota plays a crucial role in food webs, carbon cycling, and related elements. Exopalaemon annandalei carinicauda are two important forage species the Yangtze River estuary with extremely similar living habits morphological characteristics. Exploring microorganisms guts of these shrimp can help us understand survival status estuary. Therefore, this study analyzed similarities differences intestinal flora E. through high-throughput sequencing 16S rRNA gene amplicons. results showed that dominant bacteria at phylum level were Proteobacteria Firmicutes, respectively. At genus level, had higher concentrations Psychrobacter , Bacillus Pseudomonas Acinetobacter Macrococcus . In both species, contents spring than winter. most potential functions amino acid metabolism purine metabolism. Additionally, diseases greatly influenced by season. Furthermore, experimental indicated lower ratio Firmicutes to Bacteroidetes was associated larger body weight shrimp. Overall, provides theoretical reference for understanding bacterial community estuaries healthy cultivation
