Description (English)

Baltic bottoms in the photic zone of which sessile/semi-sessile epibenthic bivalves cover at least 10 % of the seabed Epibenthic bivalves cover at least 10%of the seabed and more than other perennial attached erect groups. Out of the epibenthic bivalves Dreissena polymorpha constitutes at least 50 % of the biomass.
