[Objective] To study the growth of Suaeda salsa transferred from a terrestrial habitat to a floating-bed saline habitat and its effect on the in-situ water remediation of aquaculture ponds, in order to provide methods for aquaculture water body remediation by floating bed.[Methods] The growth, physiological and biochemical indexes of S. salsa under saltwater floating bed and land habitats during the restoration period were measured. Water quality of the aquaculture ponds was monitored as well.[Results] The S. salsa was well-adapted the floating bed habitat during the experiment period. Biomass was increased significantly, and the root activity and leaf nitrogen content of S. salsa in the floating bed habitat were higher than that in the land habitat. The total nitrogen, total phosphorus, ammonia and chemical oxygen demand was 3.34, 0.20, 0.47, and 0.35 mg/L, respectively, which was lower than the control treatment.[Conclusion] S. salsa can adapt to the aquatic environment after transferred from terrestrial habitat to floating-bed saline habitat, and it can remove nitrogen, phosphorus and other elements in the water through the root absorption. S. salsa has a good potential for in-situ remediation in aquaculture pond water.
