| Abstract |
The present study is an attempt to relate environmental factors of ambient water to the physiology of the cichlid, Oreochromis niloticus. Fish were collected at 3 stations along Lake Maryût and a fourth one in an authorized hatchery as reference. Water analysis showed that many attributes of the water quality, in particular in the main basin, were far beyond admissible levels. In response, functional damage of the heart and liver in polluted fish was pointed out in view of the elevated serum enzymes (alanine aminotransferase, lactate dehydrogenase, creatine kinase, alkaline phosphatase and cholinesterase). Alkaline phosphatase seemed to potentially indicate excess phosphate in ambient water, whereas, aspartate aminotransferase was suppressed in fish caught from waters with the highest metal concentrations. Serologic data of carbohydrate, lipid and protein metabolites drew attention to the adverse effects on liver, heart and kidney functions of industrial and municipal discharges into the fishes habitats. |
