Acute Toxicity Impact Of Cadmium Sulphate On Behaviour And Histopathological Changes In Liver Of Oreochromis Mossambicus (Cichlidae)

In this study the behavioural changes and the toxic effects of Cadmium Sulphate on the histology of liver of Cichlid fish Oreochromis mossambicus was investigated. The purpose of study was to investigate whether metal (Cd) concentration and exposure period influence the degree and nature of histological changes in the liver of treated fish (Oreochromis mossambicus). Data obtained from the toxicity tests were obtained using the probit analysis and the 96h LC50 value was calculated as 600 mg/l. The abnormal behaviours were observed in the lethal concentration exposed and the histopathological changes in the liver for sub-lethal concentrations were characterized by Hepatocyte, vacuolation, increase in the sinusoidal spaces and Haemorrhage.
