Resumo: | The network IFREMER/ REMORA watches every year, from February to December, mortality, growth and quality criteria of two oyster batches ("juveniles" = one-year class ; and "adults" = two-years class), distributed among various stations of the main French oyster areas. This network is a tool for trend estimations (geographic and chronological, on the national scale) ; it must not be regarded as an accurate estimation of professional oyster ongrowings. With regard to REMORA results, generally tallied with professional observations, 1998 on the whole was a second year of low mortality. But some areas remained affected by significant mortalities such as Pen-Bé in South Brittany. The year 1998 was overall a very poor year for growth : the mean oyster weight in REMORA network was 63.5 9 in North Brittany and 60.9 9 in South Brittany. This lack of growth was also recorded in the quality indexes which were clearly under usual values. Another problem of quality is the steady increase, from year to year, of the infestation of oysters by the Annelid worm Polydora, which was particularly important in 1998 in Etel, and was still important in Morlaix, the Aber Benoit or Pen-Bé.
