Abstract: Biomarker is the newest concept in environmental biomonitoring. One of the key functions of biomarker is to provide an early warning signal of significant biological effects. The objective of this research was to determine biomarker as a water quality monitoring tool on the waste water treatment plant (WWTP). The experiment was conducted at waste water treatment plant ponds (WWTPs) of a sugar refinery by growing Nile tilapia in floating net cages for 60 days. Results show that CF and LSI decreased in all WWTP whereas the GSI value in first and second aeration ponds increased compared to the control fish. The SDH enzyme activity significantly increased in the first aeration and monitoring ponds compared to those of the other ponds. The most severe hyperemia in hepatic cells occurred in the first and second aeration ponds. The highest value of SGR and SR was observed in stabilization pond.
