Abstrakt:	The article presents comparative studies on the effects of herbicide atrazine on freshwater fish Oreochromis niloticus and Chrysichthyes auratus at Assiut, Egypt. The present study dealt with the alterations in the physiological effects of atrazine herbicide on two of the most important Nile fish, Oreochromis niloticus and Chrysichthyes auratus. The researchers investigated the hematological changes on some selected serum components and AChE. Fish exposed to atrazine in concentrations of 3 and 6 milligrams per liter showed some clinical signs such as rapid respiration and increased rate of gill cover movements, Slow down of reflexes and swimming movements and reduction in the feeding activities were also observable signs in exposed fish.
