Description 
Summary

The Dutch Demersal Fish Survey (DFS) is part of an international inshore survey carried out by the Netherlands, England, Belgium and Germany. The DFS aims at monitoring young plaice and sole in their nursery grounds in the North Sea coastal zone; hence, it covers all coastal and estuarine areas of the southern North Sea, Belgium up to Southern Denmark. The Dutch survey area comprises the coastal zone from the border between the Netherlands and Belgium up to Esbjerg (DK) and also includes the Wadden Sea, the Ems-Dollard estuary and the Wester- and Oosterschelde. The Belgium coast and the German Wadden Sea are sampled by Belgium and Germany, respectively. Three Dutch research vessels (RV Isis, RV Stern and RV Schollevaar) are involved in the DFS every year in September and October, for 12 weeks in total.
