For the development of the so-called 'Tweede Maasvlakte' in The Netherlands, 2430 ha seafloor has been transformed into land. To sufficiently compensate the effects of the land reclamation following European frameworks, a reserve in the Dutch coast was created. A monitoring programme is put in place to study if the effects of the land reclamation will be sufficiently compensated by the marine reserve. Measurements for the start situation were carried out prior to the land reclamation (T0), for the area to be developed (MVII), proposed marine reserve (MPA) and a reference area (MVR). Within T0, two surveys using shrimp trawls have been carried out in spring and autumn 2005, to sample juvenile fish and shrimp. A CTD was attached to the net, recording salinity and temperature at different depths. Additionally two beam trawl surveys with a commercial cutter have been carried out to investigate the amount of marketable fish in the areas. In both survey types water visibility (Secchi) was recorded. A fish diet study was done to investigate the relationship between fish and its prey (in- and epifauna) in the marine reserve.
