The  Vibrio  genus inhabit estuarine and marine ecosystem throughout the world and can cause severe infections in humans and animals. Previous studies have demonstrated the dynamics of  Vibrio  at both community and population levels and assessed the close relationship between environmental factors and  Vibrio  diversity and abundance, such as temperature, salinity, and dissolved oxygen. It is also generally believed that aquaculture is the fastest-growing food sector, which is also applying great environmental impacts on microbial communities in aquatic ecosystems. However, our understanding of the spatiotemporal quantification of  Vibrio  throughout the four seasons in the aquaculture zone and response to environmental factors remains poor. To explore the spatiotemporal distribution and abundance of the  Vibrio  community with their related environmental factors and detect the relationships among them, we collected 10 seawater sites spanning four seasons across the whole year in Dongshan Bay for investigating the  Vibrio  community dynamics. Marked differences in diversity and abundance of the  Vibrio  community were observed between seasons, which were mainly driven by temperature, dissolved oxygen, nitrate, and nitrite. qPCR analysis showed that  Vibrio  abundance was most abundant in the summer (5.37 × 10 6  copies/L), compared with the autumn (4.58 × 10 6  copies/L), spring (1.18 × 10 6  copies/L), and winter (1.55 × 10 4  copies/L). A total of 22  Vibrio  operational taxonomic units (OTUs) and 28 species were identified by universal bacteria 16S rRNA gene and cultivation methods, with  Vibrio fortis  the dominant in these aquaculture areas. To summarize, our present study is one of the few studies to research the occurrence of  Vibrio  in marine aquaculture of South China, and the results indicate that  Vibrio  are widely distributed in aquaculture environment and that a further risk assessment is needed to be conducted.
