Toxicity of cadmium to fishes has stimulated considerable interest in recent years. Studies have shown that other metals, vitamins, chelating agents and protein diets which alter the physiological, biochemical and behavioral aspects in fish also influence cadmium toxicity. Selenium, as a micronutrient, and zinc, as an essential metal, have been well known for many years for their role in animal physiology. Respiratory parameters of an animal are important for assessing the toxic stress, as they are valuable indicators of the functions of all vital life-sustaining processes. In the present study, the effects of cadmium on the rate of uptake of oxygen by the whole body and different tissues of the freshwater fish Channa punctatus were investigated. The influence of zinc, selenium and ascorbic acid on the toxicity of cadmium were also examined. 14 refs., 6 tabs.
