Researchers in the South-East Crimea coastal zone during the past decade indicate that the heavy metals’ ion concentration in the Black Sea waters is growing on as a result of industrial and agricultural operations. Increase of pollution in the off-shore zone bottom sediments is registered as well. In this situation monitoring of the coastal water area with mollusks permanently inhabiting this zone enables to determine the water pollution level. Accumulation of four heavy metals, such as Cd2+, Pb2+, Cu2+, Zn2+ in soft tissues of 18 months old mussels (Mytilus galloprovincialis Lamark,1819) and giant oysters (Crassostrea gigas Thunberg, 1793) introduced in the Karadag Reserve coastal zone. It has been shown that the giant oyster soft tissues accumulate high concentrations of copper and zinc. Only big quantity of zinc was found in the Mediterranean mussel tissues. These metals accumulation in oysters and mussels is stipulated by physiological needs of these bivalves. Low accumulation of the most hazardous pollutants as lead and cadmium states the possibility of mariculture development in studied area.
