Abstract
Waterchestnut was shown to be one of the most efficient agents to yield photosynthetic products among aquatic plants in littoral vegetation. Though the plant can be an agent to remove nutrient in agricultural and domestic wastes directly through its waterroots to some extent, waterchestnut plays a great role in removing nutrients through its roots from lake sediments to watercolumn of the lake.
Waterchestnut can be choked to death when its leaves are covered completely by the heavy blue-green algal bloom typical in hypereutophic lakes.
