The use  of macrophytes plants  for treatment of wastewater for nutrient removable is addressed A stuoy was conducted to ascertain  the  nutrient   reduction   potential   in  freshwater  aquaculture using  Lemna  gibba (Duckweed)   Experiments were conducted with  plastic  trays  of  dimensions 34     27  y  6 cm Wastewater from  freshwater  aquaculture was  collected and experimented under  different dilutions.  Nutrient removal and  productivity of  the  Lemna  gibba system were  studied  for  a period of ten days. the experiments were  conducted over  a period  of SO days The nutrient removal patterns were obtained for  ammonia-nitrogen,  nitrite,  nitrate and  phosphate Reductions in nutrient  in the  Lemna  gibba system are  higher  in  raw wastewater  compared to  dilutions.  Ammonia  nitrogen  had  maximum  removal  efficiency followed  by  nitrate,  nitrite and phosphate.  Biomass  productivity was  also higher  in the raw  wastewater series  than  with dilutions.  The studies indicated the survival  of Lemna gibba in low nutrient  loading  conditions and also as a potential biomass resource
