Abstract: Nanotechnology is an upcoming science which deals with the application of nanoparticles in day to day life. But it also had a impact on the environment in which nanoparticles were released as a contaminant into the aquatic ecosystem. The present study is aimed to determine the impact of cadmium nanoparticle (CdNP) in aquatic system with the help Histological and biochemical changes induced in the eye stalk of mud crab, Scylla olivacea (Herbst, 1796) when exposed to Cadmium Nanoparticles (20ppm). The histological results revealed that the CdNP induced necrosis and atrophy of the eye stalk tissues. The biochemical results suggested that treatment of CdNP had reduced the protein, carbohydrate and lipids in exposed crabs which revealed that neurohormonal factors released from eyestalk of crabs regulates carbohydrate, protein and lipid contents. The overall results showed that nanoparticle had a negative impact on the animals exposed to the aquatic system contaminated by the nanoscale materials.
