Pectinaria koreni is widely spread in the Belgian part of the North Sea in both periods. A higher frequency of occurrence was nevertheless observed in the near-coastal zone, especially in the 1994-2001period. In both periods high densities of P. koreni were observed (1976-1986 period: maximum 1,100 ind./m2; 1994-2001 period: maximum 350 ind./m2).
