The technogenic transformation of the water ecosystems under the dredging is one of the actual problems for the near-shore waters. The main primary producer and the base of food webs in the seas are microscopic algae which are suspended in waterbodies. The phytoplankton of Luga Bay (the second bay of the Gulf of Finland) was investigated during the period of Ust-Luga commercial seaport construction in the condition of continual dredging. By the results of the investigation, the fast recovery of the phytoplankton structure after the dredging was shown. The trend of changing phytoplankton structure and quantitative characteristics was not found. This indicates the stable state of Luga Bay ecosystem's primary producer and the preservation of its productional resources.
