Abstract
    This study is based on data concerning the macrobenthos fauna from Modiolus phaseolinus biocoenosis, obtained in 2006 - 2007 from 56 stations distributed on the North-Western continental shelf of the Black Sea. A total of 95 taxa belonging to 19 phyla were found. The average density of macrobenthic community was about 5249.11 indv.m-2 while their average biomass was 257.76 g.m-2. At all stations, the Polychaeta contributed most to the multi-species biocoenosis structure. All results point to a slight recovery of the Modiolus phaseolinus biocoenosis. When compared to long-term studies on macrobenthos, it is evident that the results represent only a momentary state in the succession of the open-sea communities, which have been affected by past changes, and will be subject to future changes in accordance with the variable environment, affected by climate.
