economy, water and nutrient cycling in indoor high-density aquaculture Use becomes a new topic. In this study, anaerobic hydrogen effluent (Microbiome) was used to promote the symbiosis of algae, and indoor water quality was improved to reduce water use. This study constructed aquaculture unit, including aquaculture pond (1.7 m3, 150 Taiwanese alfalfa), algae pond (1.7 m3) and a living pool (1.7 m3, 1.0 m3 filter). Microbiome was added periodically to verify the symbiosis of algae for water quality and fish growth. benefit. In the course of this study, the culture tank was replenished with algae water under reflux conditions and the reflux was closed for three days as a difference comparison to investigate the effects of water quality changes and the availability of algae on the fish. The Microbiome used in the operation is rich in thick-walled bacteria (69%), actinomycetes (27%), Bacteroides (2%) and Proteobacteria (1%) and their metabolites, as between repairing and connecting microorganisms. The metabolism and circulation functions of the substances in the environment show that the pH of the cultured water is controlled at 6.0 to 7.0, the dissolved oxygen is controlled at 6 to 8 ppm, the turbidity is maintained at 1 to 3 NTU, and the total organic carbon is maintained at 20 to 30. Mg/L, water quality can be controlled within a certain range
The stable algae phase can also be maintained, and the algae can be put into the breeding pond to enrich the biological bait in the water body, thereby reducing the feed amount and maintaining or increasing the breeding yield.
