Local distribution Macoma balthica typically occurs in the coastal zone of the Belgian part of the North Sea. In the 1976-1986 period only low densities were observed (up to 10 ind./m2) whereas densities up to 170 ind./m2 were found in the 1994-2001 period. In this period the highest densities seemed to … Macoma balthica: 5: Common: 438: 61-80 %: Scrobicularia plana: 5: Super abundant: 250: 81-100 %: Similar biotopes.
