Water microbiota sequencing of grass carp (Ctenopharyngodon idella) ponds under different aquaculture modes
This project contains 16S rRNA gene amplicon sequencing data of aquatic microbial communities from pond water samples of grass carp (Ctenopharyngodon idella) farming systems. The study aims to clarify the effects of different aquaculture management practices on water environmental characteristics and microbial community dynamics, and to reveal the driving factors of microbial community assembly in aquaculture water environments.In this study, four typical grass carp culture modes were set up, including commercial feed culture (CP), malt culture (MP), grass culture (GP), and faba bean culture (FP). Water samples were collected across the whole farming cycle, covering different growth stages of grass carp and seasonal variations (including summer and the late farming stage). For each sample, we measured core water quality parameters, including chlorophyll-a (chl-a), total ammonia nitrogen (TAN), nitrate nitrogen (NO3-N), total nitrogen (TN), total phosphorus (TP), and suspended solids (SS). Meanwhile, total microbial genomic DNA was extracted from water samples, and the 16S rRNA gene was amplified for high-throughput sequencing, to characterize the microbial community composition, diversity, interspecific interactions, and assembly processes.The sequencing data in this project can be used to explore the response of aquatic microbial communities to different culture modes, analyze the correlation between water environmental factors and microbial community variations, and provide data support for optimizing grass carp aquaculture strategies and maintaining the health of aquaculture water ecosystems.
