Abstract :
Comparative study for heavy metals accumulation in the shrimp tissue P.indicus and Caspian sea native shrimp (Palaemon elegans) showed that presence of Zinc in a higher range (70.5mg/kg) in cultured shrimp in Kolahi center in compare to that in native shrimp species , where as the result for Lead and Cadmium showed in reverse. No significant difference of Mercury concentration was observed in both of the shrimp tissue and in Caspian Sea the result of accumulation found negligible.
