Almost all heavy metals and their salts have oftenly been proven as an important group of environmental pollutants becaues they are potent metabolic inhibitors. Cadmium is non essential trace element with no biological function and highly toxic to marine and fresh water aquatic life. Several studies have shown that cadmium accumulates in specific site in the body rather than being distributed evenly throughout. In this investigation an assessment of effect of the heavy metal (Cadmium) on biochemistry of blood serum has been taken as the prime consideration because blood is good patho-physiological indicator. H-fossilis (air breather) and M.seenghla (Non-air breather) were used as test animals. Both species of fishes responded differently to the same toxicant and for the same duration of exposure. In H-fossilis there was decreasing trend in glucose, total protein, Cholesterol, urea and creatinine value while in M. Seenghala only glucose and sodium exhibited -ve trends, but all other parameter showed elevation in their value as compared with the control fish.
