Abstract
Pathological manifestations in fishes from the polluted environment reflect the deleterious effects of environmental damage to higher animals in the food chain including man. Industrial and mining wastes containing cadmium ions induced several abnormalities and metabolic disorders in aquatic animals. Though cadmium is reported to be toxic to all tissues of animals, cadmium-induced malformations in eyes of fish have not yet been described. During these investigations on acute toxicity of cadmium on the estuarine fish Ambassis commersoni, the authors observed the manifestations of creamy white eyes and protrusion of eye balls, leading to death of the fish. This paper deals with the eye malformation in cadmium-treated estuarine fish, A. commersoni. Cadmium induced behavioral changes and alteration in the glycogen levels in muscle and liver are also described.
