Description

Abstract. On the basis of the analysis of 27 samples collected by diving in 9 stations along the South Sector of the Romanian Black Sea coast, the authors present the qualitative and quantitative state of the benthic community of the hard bottom mussels in the shallow waters. The study, carried out in mid and upper-infralittoral in August 2001, reveals the occurrence of 68 species and 11 supraspecific taxa, with an average density of 750,000 indvs.m-2 and a biomass of 16,500 g.m-2: Numerical dominants are represented by worms (~ 460,000 indvs.m-2) and crustaceans (~ 270,000 indvs.m-2), and the weight dominants by mollusks – Mytilus galloprovincialis over 95% (~ 16,300 g.m-2) and crustaceans (~ 137 g.m-2). The general ecological state of the hard bottom mussel benthic community of the Romanian Black Sea coast in August 2001 can be considered satisfactory in comparison with the 1980s.
