Copper, chromium, manganese, Cadmium, Lead, and zinc were measured in seawater, marine prawn hepatopancreas, and muscle tissue in this study. Kasimedu, Lighthouse, and Muttukadu are three different areas along the Tamil Nadu (Chennai) shoreline where the trials were collected. For heavy metal analysis, an Atomic Absorption Spectrophotometer was used. During the months of July to September 2019, the mean cluster of heavy metals in water at all trail locations was Mg > Zn > Cd > Cu >Pb> Cr. Hepatopancreas > muscle > hepatopancreas > muscle > hepatopancreas > muscle > hepatopancreas > muscle > hepatopancreas > muscle > hepatopancreas > muscle > There were differences in heavy metal levels between different places, according to the current study. This demonstrates crustaceans' ability to accumulate heavy metals to detectable quantities. The chemical composition of saltwater can affect shrimp bioaccumulation of metals. Within the Bay of Bengal, Chennai coast, variations in heavy metal clusters are likely to have resulted from hydrodynamics, metal bioaccessibility of the environment, changes in tissue composition, collection stations, and pollution sources.
