Baltic infralittoral bottoms habitat dominated by Mytilidae

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 Mytilidae constitute at least 50 % of the biomass.
Physical environment
Substrate is rock and/or boulders. Depth is typically from 5 to 20 meters. Appears in all wave exposure classes. Salinity must be at least 5 psu.
Characteristic species
Mytilus spp. and Modiolus modiolus
Quality descriptors
Amount of sediment and epiphytic annual algae. Diversity, abundance and biomass of fauna.
Geographic range
Baltic Sea up to the Quark in the North.
