Since 1998, a growth and quality monitoring study of reared molluscs has been developped as part of a close collaboration between the Shellfish Research Laboratory of Normandy (IFREMER Port-en-Bessin, Calvados) and the SMEL (Syndicat Mixte d'Expansion du Littoral) Experimental Centre (Blainville, Manche). REMONOR (REseau MOllusque de NORmandie) is based on the experience gained through the national monitoring network REMORA, which protocol has been entirely applied. Adults and spat of Pacific oysters Crassostrea gigas were placed in 13 stations all along the oysters rearing areas of Normandy. These oysters had the same origin and history (i.e. age and weight) until they were dispatched on the 13 stations. 4 essential criteria were used to monitor rearing...

The national REMORA network is targeted on the studies of growth, flesh quality and mortality of a sample of cupped oyster Crassostrea gigasdistributed on 9 stations along the coast of Normandy. As a better precision is needed for regional purpose, 7 new stations have been added. A total number of 16 stations is now sampled from Chausey to Meuvaines. Weak rates of mortality have been noticed in 2002 on both adults (7%) and spat (6 %). These rates are the weakest ever seen. The mortality rates in the Baie des veys were less than 10 %. This rearing area shows usually a much higher mortality level. Growth rates were noticed weaker than usual. They slowly decline from 1999. From Mach to December, the growth rate of adults has been computed to 0,21 %/day (for a...

Estimation du stock naturel d'ormeaux (Haliotis tuberculata) dans la region de Saint-Malo.
Provedor de dados: 5
Autores: Clavier, J; Richard, O.
Abundance and biomass of an unexploited ormer population in the vicinity of Saint-Malo (northern Brittany) are estimated using a stratified sampling technique. Examinations are made be diving at 200 sites. The mean biomass of the population is about 400 tons but the stock is not evenly distributed over the studied area: the greatest densities are observed on schist substrate. Size and weight frequency distribution reveal a "top-heave" structure due to an accumulation of old individuals with low production.

The regional network REMONOR showed 2001's characteristics of growth and quality of oysters (Crassostrea gigas) in the three rearing areas of Normandy. Compared to year 2000, two additional stations along the East Coast have been settled. The summer adults mortalities have been registered between 0 % and 25 %. The average for all the rearing areas reached 6 %. Highest rates have been noticed in the Baie des Veys and the East Coast. The juvenile's mortality occurred during the same season, in summer. This year 2001 is included in lower growth years in all Normandy. This year, the West Coast growth rate appeared to be quit unusual. For the first time growth rates were in the average in the northern area that usually shows very bad performance. We can...

At the end of its third year, the regional network for monitoring REMONOR, confirms the particularities of oyster from Normandy in matter of growth and quality. Results from 2 000 are globally very close of those from 1998. Mortality of adults reached 14% and juvenile 6% which represent a low death rate. For this year the most blow area is the Baie des Veys with 31% death rate at Géfosse. Observed growth this year had been weaker than the past two years despite the spring and automnal growth. At spring, the higher recorded growth rate on the West coast with 0.42% (regional average : 0.29%). This seasonal trend seems more and more obvious every year. Regarding the classification of the special oysters, despite the change of the standard, the Baie des Veys...
