Over the experiments some factors like: pH, hardness, water temperature and dissolved oxygen which were measured respectively between 7-8.4 mg/l, 22±1 degree centigrade, above 7 PPM. The experiment duration was for 10 days and every 5 day sampling applied. Results from histological pathology It also showed that the liver and gills were in the presence of glyphosate poison It leads to symptoms such as hyperemia, cellular atrophy, bile duct, necrosis, Cloudy swelling and sinusoidal space in the liver and hyperemia, hyperplasia, necrosis, Primary and secondary filament adhesion, cramping, wailing, The shortening of the secondary gill blades in the gill tissue Over time, these symptoms increase.
