Abstract: Histopathological changes used as biomarkers in the evaluation of the health of fish exposed to effluents. One of the advantage of using histopathological biomarkers in environmental monitoring is allows examining specific target organ like gill is responsible for vital functions such as respiration, detoxification, excretion and co-ordination. The freshwater fish, Oreochromis mossambicus exposed to electroplating effluent for a period of 7, 14 and 21 days and histopathological changes were analyzed by light and scanning electron microscopy. The main histopathological changes were edema, lifting of lamellar and filamentary epithelia and lamellar fusion, cell proliferation with consequent thickening of the filament epithelium also found in fishes exposed to the electroplating effluent. The severities of the lesions increased with the time of exposure namely the hyperplasia of the epithelial cells with the proliferation of filament are epithelium and fusion of lamellar observed at 21 days. Additionally, several histopathological results obtained by light microscopy were confirmed through scanning microscopy.
