Shellfish reef found in Dutch delta
When searching for a suitable pilot location, a shellfish reef with wild flat oysters and mussels was discovered near the Brouwersdam of the coast of Holland. During one year this area was frequently monitored, to see whether the shellfish staid alive, grew and reproduced. Research was carried out by Wageningen Marine Research, Bureau Waardenburg and Sas Consultancy. Project manager Karel van den Wijngaard (ARK Nature Development): “Further monitoring of this wild shellfish reef showed out that it extended over an area of forty hectares, an area as large as 55 football fields!” Furthermore, it appears that the Dutch flat oyster (an endemic species) mainly attaches itself on Japanese oyster shells (an exotic species). Possibly the Japanese oyster can facilitate the recovery of the flat oyster, also in other areas.
