Investigation of Heavy Metals Contamination in Indian Aquaculture Shrimp -Litopenaeus vannamei

The expanding aquaculture industry in India has raised concerns about potential environmental contaminants, particularly heavy metals in seafood products. This study aims to assess the presence and levels of heavy metals in Indian aquaculture shrimp, focusing on the widely cultivated species Litopenaeus vannamei. Shrimp samples were collected from diverse aquaculture sites across India and rigorous analytical techniques were employed to quantify the concentrations of various heavy metals. Preliminary findings indicate the potential presence of mercury (Hg), lead (Pb), cadmium (Cd), arsenic (As), copper (Cu), zinc (Zn), chromium (Cr) and nickel (Ni) in the shrimp tissues. The study explores potential sources of contamination including water quality, sediments and feed to ascertain the pathways through which these heavy metals enter the shrimp cultivation environment.
