英文摘要	Microbes are important in not only driving matter cycling, modulating water quality, but also serving as food for animals in intensive aquaculture systems, in which artificial substrates in combination of biofloc technology can be applied to strengthen microbial values and animal production. However, the influence of micro-habitats created by these practices on water quality and microbial diversity and dynamics remains poorly understood. In this study, samples of three micro-habitats, the biofilms formed on immersed meshes, the suspended macro -aggregates, and the pond water were collected from limited-water-exchange ponds for rearing Litopenaeus van-namei during a period of 80 days. Using high-throughput sequencing of 16S and 18S rRNA genes and statistical analyses, we found that the community structures of both bacteria and micro-eukaryotes were similar between biofilms and macro-aggregates (ANOVA, P > 0.05), but significantly different from those in the water (P < 0.05). Alphaproteobacteria and Bacteroidetes were more enriched in the biofilms and macro-aggregates, while Cya-nobacteria and Actinobacteria occurred more in the water. Chlorophyta and Fungi were selectively enriched in the micro-eukaryotic communities of biofilms and macro-aggregates, while Ciliophora, Dinophyta, Bacillar-iophyta and Cercozoa were more abundant in the water. There were also significant dynamics of both bacterial and micro-eukaryotic communities in a specific micro-habitat, with Rhodobacteraceae, Cyanobacteria and Fungi being generally prevalent at the earlier rearing stage, while Bacteroidetes, Chlorophyta and parasitic Apicom-plexa becoming more abundant at the later stage. However, deployment of substrates and addition of molasses to the water did not significantly alter community structures of both bacteria and micro-eukaryotic communities across all samples (ANOSIM, P > 0.05). Functionally, microbes in both biofilms and macro-aggregates exhibited higher potentials of organic matter degradation and nitrogen removal, supporting the usefulness of application of biofloc technology and biofilms in recycling waste and nutrients in the shrimp ponds with limited water exchange.
