As part of Task 5.3 of Work Package 5 in the EU project, Oysterecover, which is aimed at investigating the causes and potential solutions of the decline of the European flat oyster Ostrea edulis, we investigated the efficiency of different spat collectors. The objective of these spat collectors is to provide a substrate for larvae to settle and recruit, thereby concentrating the number of oyster spat to a profitable quantity which can then be removed and reared in a hatchery. We tested three types of spat collectors, Chinese hats (a collector currently used commercially), Mussel stockings (a collectors currently being tested and used commercially by some farmers) and a plastic mesh (not a commercially used spat collector but one with an experimentally successful review in the literature).
