Resumo: | Every year, from March to December, the IFREMER / REMORA network carries out a survey of mortality, growth and quality criteria of two oyster batches ("juveniles" = one-year ciass ; and "adults" = two-years class), distributed among various stations of the main French oyster areas. In Brittany, this network includes 11 points, to which regional points can be added (15 in 2000). With regard to the Breton stations of the network, the year 2000 showed rather low mortality rates, excepted mortality of several oysters when transfered to the sea. Several areas however had higher mortality rates (&gt; 20%) : l'Arguenon, Morlaix, les Abers, Pen-Bé and Le Croisic. 2000 is a year of good growth in South Brittany (72.8 g in December), more average in North Brittany (62.8 g). The best growths were obtained in les Abers, the bay of Quiberon, the Golfe du Morbihan, Pen-Bé and Le Croisic. On the other side, North Brittany had better quality indices than South Brittany, especially the meat index which is used to sort oysters in different quality classes. 4 sites of North Brittany might be classified in the highest class ("spéciales") ; all other Breton stations might be classified in the medium class ("fines"), and no one in the lowest one. At last, a regression of the oyster infestation by the worm Polydora was observed in 2000 on the whole French network, for the first year since the beginning of the network (1993). However, this observation is less marked in Brittany, and several sites have still remained infested since the juvenile stage.
