Grey Mullet Mugil cephalus L, fingerlings were chronically exposed to sub lethal concentrations of lead (Pb) (0.1 and 0.4 mg/L for twenty-eight. The changes in the leucocytes and serum glucose, protein, and total cholesterol of the fish were determined every seven days in a renewable static bioassay system. At the end of the study, these parameters were significantly (p<0.05) elevated in the Pb - exposed groups when compared with the control group. Showing a pronounced leuocytosis in the Pb-exposed fish. The magnitude of increase was influenced by increasing of exposure period and Pb concentration. The Pb exposed fish were significantly (p<0.05) hyperglycemic and hyperbcholesteremic. The serum glucose levels on the 7th day were 26.50 ± 2.12 g/dL and 30.50 ± 0.70 g/dL in the fish exposed to 0.1 and 0.4 mg Pb/L respectively. On the 28th day, the serum glucose concent.. View More»
