Mussel beds on Black sea circalittoral terrigenous muds

Description (English)

Mixed circalittoral sediments with mud of terrestrial origin mixed with variable amounts of recent or subfossil shells, most of them belonging to the blue mussel Mytilus galloprovincialis, occurring offshore, between depths of 20 and 45 m. At these depths environmental conditions are relatively constant year-round: low light, low temperature (6-9
