Abstract Effects of several treatments in shrimp pond effluents was studied.Phosphate,total phosphorous,phytoplankton,zooplankton and bacteria,dissolved chemical oxygen demand,paniculate chemical oxygen demand,and total chemical oxygen demand were measured under five treatments,in which four biofilters were mussels Pernav Viridis,red algae Gracilaria tenuistipitata var.Liui Zhang et Xia,bacteria and mixture of these three organisms above,respectively,and the fifth one was the self~purify treatment.The results showed that 1) there were differences among the trends of fluctuation in these nutrient content,and interrelations among some nutrients were observed,2) the concentration of dissolvable nitrogen and the size of bacteria population decreased by all treatments,3) contents of COD can not be removed,but the forms of COD were transformed,4) mussel removed phytoplankton obviously.
