Abstract: Phosphate-solubilizing microorganism (PSM) can help to mobilize insoluble phosphorus for phytoplankton to use. However, the number of PSM in aquaculture pond is small. In this paper, the quantity and distribution of PSM, the adaptation scope and phosphate-solubilizing effect were reviewed. Furthermore, the feasibility of application of PSM in aquaculture pond was discussed. In view of the current culture situation, the prospect of the future research direction was made based on the preliminary research on the application of PSM in aquaculture environment. The application of exogenous efficient phosphate-solubilizing microorganisms can promote the phosphorus cycle and improve the utilization ratio of phosphorus in aquaculture pond. So the application of PSM in aquaculture pond is feasible.
