Large-scales recirculations systems for storage of imported bivalves as a means to counteract introduction of cysts of toxic dinoflagellates in the coastal waters of the Netherlands

In the coastal waters of the Netherlands and in the German and Danish Wadden Sea, at present no PSP-producing toxic dinoflagellate blooms occur. This is in contrast with the situation in a number of countries from which Dutch traders import mussels (Mytilus edulis) and oysters (Ostrea edulis). Especially bulk imports of mussels entail a risk of the introduction of cysts of toxic dinoflagellate species. These can be present within the bivalves but, when dredged mussels are concerned, particularly in accompanying mud and sand. Such cysts can be released into the coastal waters when the imported...
