In the 1976-1986 period Pariambus typicus was found across the entire Belgian part of the North Sea with a low distribution frequency. In the 1994-2001 period the distribution frequency increased but the distribution was limited to the near-coastal zone, with the exception of the eastern costal zone. The density levels increased as well: from a maximum of 220 ind./m2 in the 1976-1986 period to a maximum of 15,000 ind./m2 in the 1994-2001 period.
