Última Biochemical composition and energy value of Crassostrea gigas (Thunberg) cultured in the bay of Marennes-Oleron ArchiMer Deslous-paoli, Jean-marc; Heral, Maurice. In the bay of Marennes-Oleron the dry flesh of Crassostrea gigas ranged from 29 to 52% proteins, 10 to 23% ash, 6 to 20% lipids and 0 to 4% carbohydrates of which 48.3 ± 21.6% were glycogen. The energy value ranged from 18.84 to 23.47 joule. Mg(-1) ash free dry weight (mean 20.27 J. mg(-1). Reproductive effort varied from 17.8 to 55.9% dry weight for males, and 43.1 to 61.9% for females during the first and third year of reproduction respectively. A high energy value for female gametes (23.47 to 26.24 J. mg(-1) dry tissue) was mainly due to a higher level of lipids (17.3 to 23% of dry tissue) in female gametes as compared to that in male gametes (5.9 to 12.3% of dry tissue). During the period of mass-loss which began in October and finished in March, the...

(Gastéropode, Calyptraeidae) dans le bassin de Marennes-Oléron : composition et valeur énergétique des individus et des pontes ArchiMer Deslous-paoli, Jean-marc; Heral, Maurice. In the bay of Marennes-Oléron, the shell represents 60% and the dry flesh from 3 to 8.5% of the total weight of Crepidula fornicata. Seasonal changes in the biochemical composition of the dry flesh show two periods of spawning for the females and a single period of reproduction for the males, and that the main component of the energy reserve is glycogen. The mean energy value of Crepidula fornicata varies between 15.1 and 19.3 joules/mg of ash-free dry weight of flesh (average 17.7) and this value is higher in the males than the females, during aIl the periods of reproduction. The females lay, as early as their third year, about 56 egg capsules at each spawning, containing a total of Il 725 eggs with an energy value of 22.4 joules/mg ash free dry weight.

Ano: 1986 URL: http://archimer.ifremer.fr/doc/1986/publication-2964.pdf The shell organic content in the energy budget of Mytilus trossulus from the South Baltic ArchiMer Wolowicz, Macciek; Goulletquer, Philippe. La quantité de matière organique et sa valeur énergétique ont été évaluées pour les coquilles de Cerastoderma glaucum, Macoma balthica et Mytilus trossulus de la baie de Gdansk, par extraction chimique et microcalorimétrie. Le contenu moyen en matière organique varie de 0,54% chez C.glaucum, à 5,21 % chez M. balthica et 5,92% chez M. trossulus. La valeur énergétique de la matière organique de la coquille varie entre 15,15 (± 1.41) j .mg-1 chez M. balthica, 20,17 (± 1,60) j.mg-1 chez M. trossulus et 23,88 (± l ,56) j.mg-1 chez C. glaucum. Le contenu en matière organique de la coquille et sa valeur énergétique sont spécifiques, et corrélés avec la microdistribution géographique (facteurs de l'environnement) de la population, ou avec le type de sédiment.
