摘要： In order to study the effects of carbon source addition on the bacterial community, water quality and shrimp growth in the recirculating aquaculture system of Litopenaeus vannamei, sucrose with 50% of the daily feed was added daily to the system from the middle stage of culture. The bacterial communities in biofilters, aquaculture waters and shrimp intestines were measured using an Illumina MiSeq platform. The addition of sucrose did not significantly improve the regulation of nitrogen in the water, although there was a tendency to increase shrimp production. The addition of sucrose also had little effect on the bacterial community of water and intestine, but had significant effects on the bacterial community in the biofilter. Carbon addition transformed the dominant bacterial taxa of the biofilter from the Proteobacteria dominated by Rhodobacteraceae to the Planctomycetes dominated by Planctomycetaceae. In this study, the characteristics of the bacterial community and the effects of carbon source addition in the recirculating aquaculture system of L. vannamei are presented, which provides a basis for microbial management in the recirculating aquaculture system of L. vannamei. In view of the unknown role of numerous bacterial groups, the function of the bacterial community needs further study.
