Assessment of energetic requirements of reared molluscs and of their main competitors ArchiMer
Deslous-paoli, Jean-marc.
In the context of aquaculture in open sea• the amount: and qua11ty of food is variable according to the season and the physical flux in the ecosystem (carrying capacity ecosystems ). Thus to predict the potential al production of a cultivated ecosystem, it is mandatory 'co know ~he seasona1 changes in organisms energy balance of cultivated organisms. These changes result from the environmental variability either in the temperature or more significantly in the nutrients supply (Bayne and Newell, 1983). The techniques of physiological energetics allow to understand the adaptations of the energy balance in bivalve molluscs and to calculate the complete energy budget all over the seasonal variations of the field. Such studies are few, they include...

Observations sur le cycle complet d'élevage de palourdes et de clams en surélévation ArchiMer
Latrouite, Daniel; Claude, Serge.
First rearing attempts with the european clams Ruditapes decussatus, the pacific clams Ruditapes philippinarum and the clam Mercenaria mercenaria have been realized by placing the bood into grating cages above the ground. This technic permits a good survival during the so-called "pre-growth" stage. However, if rearing of juveniles is persued beyond 2 centimeters, growth is strongly delayed and mortality increases due to valve distortion and shell infection by parasitic worms.
