Based on the results of concentrations, using a numerical method, loadings of pollutants from this shrimp pond was estimated and shown in Table 1. It shows that in untreated effluent COD was the highest, followed by TSS, BOD5, TN, P and Chl-a in that order. Discharging such water into the surrounding surface water could result in fish suffocation due to suspended solids, lack of oxygen due to sudden surge of low oxygenated water and algal blooms due to nutrients such as nitrogen and phosphorus. Therefore, it is recommended that the pond water must be treated before discharge. One of the treatments could be retention in sedimentation ponds (Nyanti et al. 2010; 2011) and subsequent controlled circulation to enclosed mangrove area that is large enough to treat the effluent as reported in Shimoda et al. (2005)
