Abstract: Although many papers dealing with the cadmium toxicity in aquatic organisms, the expression of oxidative stress induced by heavy metals is still due in most common freshwater fishes. The present study deals with the toxicity of cadmium in fry of Labeo rohita and Cyprinus carpio. Preliminary toxicity tests results the sub-lethal concentration of cadmium for Labeo rohita and Cyprinus carpio were observed as 0.1998ppm and 4.938ppm respectively. It was noteworthy that 96h exposed fish fry recorded highest value of carotenoids such as 1.259±0.208mg/100 mg body weight and 1.291±0.079mg body weight in Labeo rohita and Cyprinus carpio respectively. The percent increase in exposed fry against to control was observed high at 10th day (61.65%) in Labeo rohita while in Cyprinus carpio, 32.29% at 24h.
