It was only in September 1967 that we observed in Ostrea edulis the symptoms of a disease that had already been infecting Crassostrea angulata for some time. The disease manifests itself in gills that become indented rather deeply and appear, in extreme cases, completely eroded. Since we focused our observations on Portuguese as well as flat oysters, we were able to compare the disease's manifestation in both species. The extreme stages only very rarely exist in O. edulis, since the most infected oysters are in this stage at stage II of the classification. The indentations are usually distinct and the perforations that manifest themselves cannot be seen in C. angulata even when in the early stages. We have not observed the presence of indentations or... |
