Variations des productions de biodépôts (feces et pesudofeces) de l'huître Crassostrea gigas dans un estuaire macrotidal : baie de Marennes-Oléron ArchiMer
Razet, Daniel; Heral, Maurice; Prou, Jean; Legrand, Jacqueline; Sornin, Jean-marc.
The continuous obtention of current (speed and direction) turbidity and phytoplanktonic fluorescence was achieved for 9 successive days during the month of May 1988. Each two hours, during the day, the faeces and pseudofaeces productions of 7 oysters have been sampled individualy. The filtration rate were calculated in continuous. It appeared that the concentration in particular matter and also the planktonic fluorescence fluctuated in direct relation with the water depth, the origin of the water masses and the speed of the wind. During the tidal cycle the mean filtration rate was constant which induced a food consumption largely variable. The oysters were always above the limit of pseudofaeces production which regulated the ingested quantity. Their...

Does bivalve mucus favour the growth of their main food source, microalgae? ArchiMer
Cognie, B; Barille, Laurent.
Bivalves, by releasing inorganic nutrients, can stimulate the growth of the primary producers on which they feed. Dissolved excretion and mineralization of biodeposits (pseudofaeces and faeces), two indirect processes related to their feeding activity, have already been identified. This study investigated whether microalgal growth is also dependent on the mucus secreted by bivalves and rejected with their biodeposits. An experimental study based on algal growth tests was conducted to determine whether the mucus coating the pseudofaeces and faeces of the oyster Crassostrea gigas (Thunberg) could stimulate the growth of nine marine microalgae: a Prasinophyceae [Tetraselmis suecica (Butcher)] and eight Diatomophyceae [Amphora sp. (Ehrenberg), Chaetoceros sp....

Transformation du matériel fécal de Crassostrea gigas: évolution biochimique à court terme ArchiMer
Deslous-paoli, Jean-marc; Jousset, Jacques.
Que ce soit dans les études de digestion des mollusques effectuées dans le milieu natural ou en laboratoire, ou pour mesurer l'impact des élevages de mollusques sur les sols sous-jacents, l'étude des biodépôts des mollusques se généralise. Cependant, les temps de séjour dans l'eau peuvent entraîner des modifications très importantes dans la composition de ces biodépôts.
