Bonamiasis has progressively destroyed the flat oyster fisheries of the mainland Europe and has made serious inroads into fisheries in Britain and Ireland. Following studies of the apparent linkage between disease susceptibility and variations in environmental conditions in one population of O. edulis the attention of this study turned to the investigation of anecdotal evidence of differential susceptibility to bonamiasis of O. edulis from different sites around the British Isles. In particular, animals from parts of Loch Sween on the west coast of Scotland appeared to be immune despite ample opportunity for infection by stock movements into the area prior to the imposition of movement restriction. In 1990 a series of field trials were initiated by the Ministry of Agriculture Fisheries and Food, Fish Diseases Laboratory, Weymouth in which animals from three sites around the UK were placed in a former oyster rearing site known to be still infested with Bonamia. The work presented here describes the differentiation of the three experimental groups using a combination of physiologica, biochemical and immunological methods as means of investigating the apparent differences in resistance to bonamiasis. O. edulis were obtained from Loch Sween, Scotland, Conwy, north Wales and from the Solent on the south coast of England.
