The network IFREMER/REMORA has watched every year, since 1993, from February to December, mortality, growth and quality criteria of two oyster class-size ("juveniles" of the first-year c1ass and "adults" of the second year c1ass), distributed among various stations of the French oyster areas. This has provided a quite standard and simple annual assessment of the rearing results, generally tallied with professional observations. From year to year, data series have been obtained, from which mean values (references), chronological trends or spatial differences can be analysed. Results in Brittany, from 1993 to 1998, show that, in a "normal" year, 30 g oysters grow to 60-80 g at the end of the year, with a mortality rate of 10-15%. Mortality occures mainly in...

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). With regard to the Breton stations of the network, the year 1999 showed a small increase of mortality rates, both in adults alter their transfer on the REMORA stations and in juveniles during the Summer season. this was particularly observed in Morlaix, Aber Benoît and Pen-Bé. Although it was better than 1998, the year 1999 was a poor year for growth, especially in North Brittany (62.5 g in...

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...

Prévention des mortalités estivales de naissain d'huîtres creuses. Expérimentations sur estran (Rivière d'Auray, été 1998). 1 : comparaison de différents lots de naissain. 2 : tentative "d'endurcissement» du naissain".

Cupped oysters, Crassostrea gigas, often suffer abnormal mortalities during summer, at one year of age. Both scientists and professionnals are interested in finding practical methods to reduce these mortalities. The present study tries to answer two questions : 1- are there any differences of summer mortalities among various batches of spat available from spat collection areas (Arcachon and Charentes) ?  2- is it possible to improve summer survivals by wintering the spat at high air exposure locations (« hardening » procedure) ?  The first comparison did not reveal any significant difference between the 16 batches of spat tested (mortalities between 5 % and 30 %).  The second comparison in the same summer conditions was not able to show to any improvement...
