Abstract: The research paper is focused on distribution of toxic metal in various tissues of different shrimp species, and in surface and bottom water sediments. The possible roles of these trace elements in this regard are emphasized. Moreover, patterns of toxic metal bioaccumulation and their order of occurrence have been evaluated. Another part of this paper deals with comparison of the related data from different aquatic environments as well as existing guidelines and limits for human consumption. Comparison between the mean concentrations of the toxic metal in Carapace, gills, remaining body tissues and whole body tissues and in water samples are compared with existing guidelines indicate that the concentrations of Zn, Fe, and Na are well below the permissible levels for human consumption. However the concentrations of Cu and Pb were observed somewhat greater than some of the recommended levels as prescribed by FAO/WHO and cited literature.

Key words: Toxic metals, Creak, Shrimps, sediments, contamination
