Influence of aquaculture practices on microbiota composition and pathogen abundance in pond ecosystems in South China.

ABSTRACT: Pond microbiota play a crucial role in maintaining water quality and the health of aquaculture species. This study aimed to explore the relationship between pond water and sediment microbiota (especially potential pathogens) and physicochemical parameters under different aquaculture conditions. Samples of pond water and sediment were collected from 21 monitoring sites across eastern, western, and northern Guangdong, and the Pearl River Delta in November 2021, March 2022, and July 2022. Microbial structures were analyzed using high-throughput sequencing of the 16S rRNA gene. The results indicated that sediment microbiota distribution was more uniform than that of water microbiota. Additionally, sampling time significantly influenced the uniformity of water microbiota distribution more than
