The electroplating industry effluent is discharged indiscriminately in to the environment with out proper treatment. This poses havoc to the water body, which could be seen in the physiology and biochemistry of the chosen fish, Oreochromis mossambicus. The metals strongly present in the electroplating effluent is chromium and nickel which is being tested individually and collectively to assess its toxic nature. The intensity of the toxicity of synergetic action of these metals is much stronger than individuai effect. The result is being noticed in feeding budget and respiratory physiology of the fish, Oreochromis mossambicus. Ail parameters of the feeding budget show a significant result in the synergetic effect of these metals. Subsequently the respiratory rate and oxygen consumption of the fish in the stress medium is highly affected by this combination. A serious threat is observed in the environment by these metals and a proper treatment is suggested before releasing into the environment.
