Histopathology of the Gill, Liver and Kidney Tissues of the Freshwater Fish Tilapia Mossambica Exposed to Cadmium Sulphate
نویسنده
چکیده
An investigation on the effect of the heavy metal, cadmium sulphate (CdSo4) on the gill, liver and kidney of the Tilapia mossambica was carried out in the laboratory. Sixty fishes were exposed to continuous exposure to sub-lethal concentrations (0.084mg/l) of cadmium sulphate for a period of 20 days. The gill, liver and kidney of fish were removed for histological examination. The results showed that the degree of distortion of the gill, liver and kidney was proportional to the exposure periods and concentration of the metals was found to be dose and time dependent.
