“…The problem of prediction of dredging and dumping influence on benthic communities is important for sustainable development of deposit sites regions and adjacent waters [5,[11][12][13][14]. Laboratory tests with different types of organisms were carried out, and this data was used for estimation of dredging works influence on benthic communities.…”

The goal of the fulfilled research is the study of the influence of the sedimentary suspension from the dredging material on the benthic hydrobionts. In laboratory aquariums six series of experiments were carried out with triple replication on the ability of different benthic organisms to dig out the soil strata due to their periodic burying by marine sand. These experiments were oriented on biota of Eastern Gulf of Finland and the Neva Bay, where a number of deposit sites for dredging material are located presently. Representatives of three main groups of hydrobionts of these areas were selected for experiments – Chironomidae, Gastropoda and Oligochaeta. The ability of different hydrobiont species to overcome the stress effect of the burying under the dredged material was estimated quantitatively. The results show, that the resistance of the studied species to mechanical burying is decreasing in accordance to the scheme: Chironomus plumosus > Melanoides tuberculata > Tubifex tubifex, and depends from the thickness of the layer of dredged material.

“…The resistance of benthic hydrobionts to impact depends not only from the biological peculiarities of different species, but also from specific biotope, and composition of dredging material [5,6,[10][11][12][13][14][15].…”

“…In 1999-2019 the program of the Ecological Monitoring of Underwater Deposit Sites (EM UDS) for the Eastern Gulf of Finland and Neva Bay was developed and used [1][2][3][4][5][6][7][8][9]. Principal questions and goals of the EM UDS are: (1) revealing of the short-and long-term environmental effects of the dumping of the dredged material, and establishing the difference between the natural and anthropogenic trends of the coastal ecosystems near the dredged material deposit sites; (2) estimation of reversibility / irreversibility of trends and changes in coastal ecosystems due to influence of the dumping of dredged material; (3) finding the ways of minimizing and compensation of negative effects on the coastal environment [3,4,[10][11][12][13][14][15].…”

The goal of the paper is summarizing the results of the 20-years monitoring of the deposit sites of the dredged material in the Eastern Gulf of Finland (EGoF) and in the Neva Bay. The biotic and abiotic components of deposit sites ecosystems were observed there in 1999-2019, with using standard monitoring methods, in order to reveal effects of dumping on hydrobiologic communities and to determine their environmental status. The Biota Condition Index for 6 deposit sites was calculated and compared to areas which are not stressed by dumping. It is shown that the biological communities (especially – benthic) in the deposit sites areas are enormous not-sustainable and start their succession from the zero point every time after repeating stressing effect of dumping.
