摘要

Tilapia fish (Oreochromis niloticus) samples were collected from three selected stations(Kafr El-Zyat and Tamalay on Rosetta branch of the River Nile and Shanawan drainage canal at Shanawanvillage, Egypt). The alteration in some blood parameters (red blood cells count and white blood cells count,hemoglobin, packed cell volume, glucose, protein, albumin and globulin and albumin/globulin ratio, A/G) andhistology of liver and ovary were studied in relation to different types of pollution. Results showed increasednumber of white blood cells, protein, albumin and globulin and A/G ratio especially at Kafr El-Zyat station,which received industrial wastes. On the other hand, it is noticed an increase in red blood cells, hemoglobinand packed cell volume at Tamalay station, which received agricultural wastes. However, there is an increasein glucose at Shanawan station, which received agricultural and sewage wastes. Histopathological alternationsof liver include degeneration, necrosis, fibrosis, hemorrhage, hemolysis, edema, dilation, thickness,congestion, stagnant blood and branching. While, the histopathological alternations of ovary includehyperplasia in granulose, separation of yolk from granulose, separation of theca, Atresia, hemorrhage,hemolysis, degeneration and necrosis. It was concluded that the wastes including industrial agricultural andsewage has a negative impact on O. niloticus fish health.
