In the lab experiments, zoobenthos, such as Bellamy a aeruginosa, showed effective ability in decreasing aquatic plants (e.g. Eichhornia crassipes) residues. The ultimate removal rate of SS (Suspended Solid) of the control was 8.9%.

• 在室内买验中；底栖动物(如太湖铜锈环棱螺)对水生植物(如凤眼莲)的残体有明显的去除作用；实验结束时；对照组对SS的去除率为8.；9%25;
