| - The four calcium concretions of various structures of the farm cultivated Portuguese oyster: pseudo-nacre, hypostracum, prismatic layer and chalk masses, show, in order, falling densities going from 2.58 to 0.51.- Based on the dry matter weight, the total organic matter and phosphorus content increases, on the contrary, in the same order.- The calculation demonstrates that the phosphorus density (P.D.), that is to say the amount of phosphorus X10 000 per volume unit of these concretions, follows the same descending order as the densities. In other words, to create 1 cc of pseudo-nacre shell (P.D. = 0.81), grypheae will use more phosphorus to create the same volume of chalk (P.D. = 0.31). In this case, they save phosphorus.[...] |

| Citric and malic acids, products of the intermediary cycle, are usually found in the different vertebrate tissues; however, the same acids are not necessarily found in invertebrates and in similar quantities. This study aims to establish a comparison between the latter and superior animals. Our study material consists of two crustaceans (Nephrops norvegicus Leach and Maia squinado Latr.), a gastropod (Haliotis tuberculata L.) and a lamellibranch (Pecten maximum L.). |

| De temps immémoriaux.des techniques furent mises au point, visant à conserver intactes, au sein d'un liquide relativement stable, les précieuses propriétés alimentaires du poisson. C'est ainsi que naquirent d'abord les produits complexes résultant à la fois d'une autolyse et d'une bactériolyse en milieu saumuré. |
