| This paper presents results of studies carried out on the microstructure, composition of organic matter and amino acids in abnormal shells of adult Pecten maximus. Results indicate that abnormal P. maximus shells can have two types of brown material on the inner layer of the valves. Brown calcified areas can be present and they have abnormal crystals on the internal foliated layer of the shell. An index (MIBC) was developed to describe this type of abnormality that depended on the extent of the brown areas. The other type abnormality had brown material consisting of uncalcified membranes that were embedded in mud tubes made by Polydora sp. worms. The amino acid composition of these two materials was completely different. When compared to white (normal)... |
