ABSTRACT
The compound known as effective microorganisms (EMs) is widely used in aquaculture to improve water quality, but how they affect the health of Chinese mitten crab (Eriocheir sinensis) is unclear, especially in terms of intestinal microbiota and serum metabolites. In this study, we fed juvenile crabs with an EM-containing diet to explore the effects of EM on the physiological status, intestinal microbiome, and metabolites of E. sinensis. The activities of alanine aminotransferase and alkaline phosphatase were significantly enhanced by EM, indicating that EM supplementation effectively enhanced the antioxidant capacity of E. sinensis. Proteobacteria, Tenericutes, Firmicutes, Bacteroidetes, and Actinobacteria were the main intestinal microbes in both the control and EM groups. Linear discriminant effect size analysis showed that Fusobacteriaceae, Desulfovibrio, and Morganella were biomarkers in the control group, and Exiguobacterium and Rhodobacteraceae were biomarkers in the EM group. Metabolomics analysis revealed that EM supplementation increased cellular energy sources and decreased protein consumption, and oxidative stress. Together, these results indicate that EM can optimize the intestinal microbiome and serum metabolites, thereby benefiting the health of E. sinensis.(AU)
