摘要

The wastewater from freshwater fish farming is responsible for nutrient enrichment in receiving waters. This frequently causes localised problems for the management of the freshwater environment. Conventional wastewater treatment systems are costly to install and operate. This paper investigates the potential of an alternative system. Untreated wastewater from a recirculation system used to culture fish was passed through three treatment systems containing different species of aquatic macrophyte: Rorippa nasturtium- aquaticum (the emergent system); Azolla filiculoides (Lam) (the free floating system); and, Elodea nuttallii (Planch.) (the submersed system).
