<P><B>Abstract</B></P> <P>This study evaluated the adverse effect of wastewater effluents on three fish species, <I>Carassius auratus</I>, <I>Zacco platypus</I>, and <I>Zacco koreanus</I>, collected in the Eungcheon, Mihocheon, and Busocheon streams, respectively. Fish gills, liver, and kidneys from the mixing zone (MZ) and sites upstream (US) and downstream (DS) of the MZ were analyzed for oxidative stress responses and histology. Catalase and glutathione <I>S</I>-transferase activity was significantly higher at MZ and DS than from US (<I>p<</I> 0.05), indicating induction of antioxidant defense mechanisms. Additionally, degree of tissue changes (DTC) indicated highest histopathological alteration in MZ, followed by DS and US. Integrated biomarker response (IBR) for oxidative stress and histopathological alterations showed higher values consistently for <I>Z. koreanus</I> than other two species. Water temperature, EC, and TN levels seemed to be responsible for the observed biomarker responses. These findings indicate that thermal hot spring effluent discharged into Busocheon steam induced the most significant impact on the cool water species (<I>Z. koreanus</I>). Overall, this study suggests that the IBR index is a very useful tool for monitoring <I>in situ</I> adverse effects of wastewater effluents on fish, particularly for histopathological alterations representing prolonged impact.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The IBR study identified the adverse effect of effluent discharge on fish clearly. </LI> <LI> The cool water species was the most impacted by thermal hot spring effluent. </LI> <LI> Pathological alterations gave more consistent IBR index than oxidative stress. </LI> </UL> </P>
