In the eastern part of the Barents Sea, there are 3 types of settlements of the bivalve mollusk Macoma calcarea. At low positive temperatures (from 0.6 to 1.3 оC),juveniles predominate on sandy-silty soils in settlements with low biomass, uneven growth and high mortality. In colder water masses (–0.4...–1.5 оC), M. calcareasettlements consist of long-lived, evenly growing large individuals that form high biomass values. In the settlement of group I, there was an increased elimination of certain size classes. The distribution of settlements depends little on the depth and salinity.
