ABSTRACT

 

The present study was designed to investigate the effects of Cadmium Chloride on a fresh water fish, Oreochromis mossambicus (Peters) and its ecological implications. Exposed fishes appeared lethargic when compared to control fish. Inappetence and ataxia was observed in the exposed fish. Exposed fishes showed erratic movements, loss of equilibrium, gradual onset of inactivity etc. when compared to control fish. Drastic depletion in sodium, Potassium, Calcium and Magnesium ion content in the cadmium chloride exposed fish tissues was marked when compared to the control fish. In case of sodium ion the liver was highly affected, for potassium ion the liver of the exposed fish was also highly affected, for calcium ion the muscle of the exposed fish was most affected and for magnesium ion, the brain tissues were affected. The liver was worst affected than muscle and brain. The brain tissue of the exposed fish was least affected.

 

Keywords : Fish, Cadmium Chloride, Na+, K+, Ca++, Mg++ concentrations.
