Resumo: | This study presents the main results of oyster growth obtained experimentally in 2002 and 2003, in the farming area of Cancale before the leases reorganization of 2004. According to the REMORA monitoring network from 1990 to 2004, the oyster growth in Cancale bay may be characterized by an average annual weight gain (around 30g per year), a rather weak meat content compared to other regional oyster sites, and an exceptional quality of shell (absence of blisters, few Poly do rd). Spatially, the oyster farming area of Cancale shows rather homogeneous performances of breeding, in spite of the muddy southern area. In addition an experimental trial in 2003 allowed to evaluate favourably the potential of the new oyster area of Saint-Benoît : in these experimental conditions of low density, individual oysters were able to gain 50 g of whole weight per year, instead of 30 g in Cancale bay. The available data on environmental parameters (temperature, salinity, chlorophyl-a) are typical of coastal bays with low terrestrial impact. Turbidity which reflects sedimentary and hydrodynamic conditions is moderate at high tides, but may be extremely high under a low water column, at spring tides.
