| Abstract: |
| Cultivations of Perinereis aibuhitensis and Gracilaria tenuistipitata with marine aquaculture wastewater were conducted under laboratory condition. The result showed that Gracilaria tenuistipitata could absorb dissolved inorganic nutrients and Perinereis aibuhitensis could consume organic matter in sediment. After treatment for 7days, the concentrations of NO3--N, NO2--N, NH4+-N, PO43--P, COD and organic matters in sediment decreased， respectively. At the same time，Perinereis aibuhitensis and Gracilaria tenuistipitata grew well with average growth rates of 2.30 mg/g and 80 mg/g, respectively. The results provide a posibility for Perinereis aibuhitensis and Gracilaria tenuistipitata to be applied in the purification and cyclic utilization of wastewater from marine aquaculture plants. |
