Title

ФАУНА ЗООБЕНТОСА ЮГО-ВОСТОЧНОЙ ЧАСТИ БАЛТИЙСКОГО МОРЯ (ГДАНЬСКИЙ БАССЕЙН) В РАЗНЫЕ ПЕРИОДЫ ИССЛЕДОВАНИЙ = Zoobenthos fauna of the southeastern Baltic Sea (GdanskBasin) at different research periods

Abstract

For 275 years of research in the Gdansk Basin, 225 species of zoobenthos have been identified. The phylum Arthropoda formed 54 % of species richness of the area, phylum Annelida – 26 % and phylum Mollusca – 9 %. Only 11 % of the total number of species falls for the proportion of phyla of benthic invertebrates (Cnidaria, Porifera, Nemertea, Platyhelmintes, Cephalorhyncha, Bryozoa and Chordata). During 20012016, 90 species of zoobenthos were found in the Russian Exclusive Economic Zone (Russian EEZ), which makes up 40 % of the current species richness of the Gdansk Basin. The low species biodiversity of the Russian EEZ in comparison with the neighboring waters of the Polish EEZ can be explained by the absence of natural shelters and estuaries of large rivers which are an appropriate shelter and habitat for many zoobenthos species. The obtained data on species composition of zoobenthos are consistent with and significantly supplement the list of zoobenthos species (21 species) during the research period since 2001 till present, which more fully reflects the current species composition of zoobenthos of the Gdansk Basin. By the early 2000s, the species composition of zoobenthos of the Gdansk Basin has been described almost completely, and now the list of species is mainly added by invasive species. There are 31 invasive species in the Gdansk Basin, 17 species of which inhabit the waters of the Russian EEZ. The list of zoobenthos species by HELCOM [2012] for the parts of the Gdansk Bay and the eastern part of the Gotland Basin corresponding to the boundaries of the Gdansk Basin has been corrected. The lists of species in the eastern part of the Gotland Basin and Gdansk Bay have 48 species that are not found in the waters of the Gdansk Basin. Presence of freshwater representatives of Odonata, Hemiptera and Mollusca (except for Radix balthica) within the eastern part of the Gotland Basin and Gdansk Bay is doubtful.
