Abstract:	This study integrated constructed wetlands (CWs) into a recirculating aquaculture system, in which CWs were used as a facility for aquaculture water treatment so as to regulate the water quality in fishponds and reduce pollutant level of the fishpond effluent. Performance of the constructed wetland in removing the major pollutants from the recirculating aquaculture water was investigated, and the effect of wetland treatment on water quality of the fishpond in the recirculating aquaculture system was examined. Results of water quality monitoring for influent and effluent showed that constructed wetlands effectively reduced TSS (54~78%), turbidity (52~65%), chlorophyll a (54~68%), and BOD5 (27~46 %). The treatment wetland regulated water quality sufficiently in the recirculating fishpond, which was significantly better than that in a control fishpond without connection of CW. Furthermore, the wetland treated effluent always satisfied a national discharge standard for aquaculture farms (i.e. TSS <30 mg/L, BOD5 <30 mg/L, COD < 100 mg/L).
