Fouling of hydrotechnical structures in western Peter the Great Bay, Sea of Japan

We studied the fouling of piers and quays in Amurskii and Pos’et bays, the Sea of Japan. The main fouling communities and groupings were identified. They were usually dominated by bivalves, the musselMytilus trossulus and the oysterCrassostrea gigas. The exotic speciesBalanus improvisus was found to naturalize in the fouling on the hydrotechnical structures of the Amurskii Bay. The qualitative composition of the fouling of the structures examined was compared using cluster analysis.
