One of the global problems in developing and the developed countries is contamination of aquatic ecosystems to heavy metals. In this study, the amounts of cadmium (Cd) in the shell of Amphibalanus improvisus (barnacle) and Mytilaster lineatus (mussel) were measured as biological monitoring marker of Cd on the central southern coast of the Caspian Sea. Samples were collected during four consecutive seasons between October 2015 and October 2016 from the coast of the Mazandaran province. The hard tissue of the samples was chemically digested and then the Cd was analyzed by atomic absorption spectrometry. The results showed that the maximum and minimum Cd concentration for barnacle (32.96 and 1.46 µg/g dry wight) was observed in spring and winter respectively, while the values for mussel have been 8.16 and 0.72 µg/g dry wight. These species can be introduced as a biological indicator due to the accumulation of Cd in their shells with concentrations higher than the water and sediment.
