Histopathological changes in gills, liver and kidney of fresh water fish, Tilapia zillii, exposed to aluminum

Abstract

The present study was carried out to study gills, liver and kidney histopathology in the freshwater fish, Tilapia zillii  which exposed to three levels of aluminum (25, 50, and 100 µg/L) for 96 hour in acidic soft water (pH 6.0). Several histopathological changes were observed in fish organs would serve useful purpose in evaluating the toxic effects of aluminum. Histopathological changes in gills, Liver and kidneys observed microscopically showed increasing degrees of damage in the tissues in correlation with the concentration of aluminum, while gills, liver and kidneys of control groups exhibited a normal architecture.
