| Calcification abnormalities linked to a brown coloration of the internal layer of the valves have been observed on scallops - Pecten maximus - in different rearing sites of Brittany. Scanning electronic microscopic (SEM) observations demonstrate that the brown pigmentation is associated with various modifications of the foliated microstructure of the internal layer of the shell. Very brown shells have been compared to healthy white shells with different methods. According to the amino acid analyses, the production of the soluble organic matrices appears to be preserved in the diseased shells. A small but significant decrease in the aspartic acid content has been observed in the insoluble organic matrix of the brown shells. The Ca content is the same in the... |
