We assessed the metal-accumulating ability of the shrimp Penaeus indicus for Nickel (Ni) in 2008. Shrimps were seasonally (autumn and winter) collected from Jask coastal area, East of Hormuzgan province in the Persian Gulf. The samples were washed with seawater and dried with the help of freeze dryer and digested using a microwave digester in a super-pure nitric acid solution. The Nickel concentration was determined with Atomic Absorption Spectrometers (AAS). The result showed the mean Nickel concentration of male and female in autumn and winter were 0.007-0.084 and 0.007-0.087µg/g of dry weight, respectively. No significant differences in concentrations of Nickel in shrimps (male and female) and seasons (autumn and winter) were detected (P>0.05)
