Characteristics of gut microbiota in <i>Penaeus vannamei</i> shifted with elevated salinity.

ABSTRACT: An increasing number of studies have evaluated the effects of host, dietary, and environmental factors on the gut microbial community of Penaeus vannamei. However, the characteristics of the gut microbial community of this species in hypersaline aquaculture environments have not yet been clarified. Our findings demonstrate that salinity has a strong impact on the gut bacterial community of shrimp. The alpha diversity of the gut bacterial community of shrimp decreased with salinity. Significant differences in the composition and abundance of the core gut bacterial taxa were observed among ponds with varying salinity, and only 13 shared core operational taxonomic units (OTUs) were identified; the abundance of potential opportunistic pathogens decreased significantly in hypersaline env
