Abstract

Diazinon ultimately finds their way into aquatic habitats such as rivers, lakes and ponds, and has been found to be highly toxic in aquatic organisms specifically to fishes. Malunggay is a plant that is widely cultivated in the Philippines, which is wellknown for its benefits in providing different vitamins, minerals and as an antioxidant, in order to further explore the different uses of Malunggay, a test was done if it could remediate the harmful effects of diazinon to fishes. After treating with T1 and T2 there are no significant changes in the physical attributes of the Clarias gariepinus (African Catfish). The Clarias gariepinus (African Catfish) damage was observable only in its internal parts, namely; the liver and the gills. Behavioral changes are seen upon applying T1 and T2 to Clarias gariepinus (African Catfish) such as the swimming pattern and breathing pattern. Histopathological changes in the gills and liver has recovered from the exposure to diazinon where among the two treatments ,T2 shows most effective as observed in the histopathological examinations.T2 shows full recovery as seen in the tissues of the gills and liver.
