Abstract: Recirculating aquaculture system(RAS)is an environment-friendly and promising aquaculture model. Bacteria play multiple functions in RAS. Its quantity and community structure are closely related to water quality and fish health in RAS. This paper summarized the research progress on the bacterial community structure in RAS for marine fish and analyzed the constitute, diversity and function of the bacterial communities in microbial vectors, seawater, fish skin and digestive tract. This paper provides a reference for the healthy culture of marine fish in RAS.

Key words: recirculating aquaculture system, marine fish, bacteria, community structure
