| The first half of 2007 is characterised by very low summer mortality rates (spring mortality has not been analysed due to the bad quality of the original batch). This low rate concerns the two different size classes of each station except Géfosse (BV02) where a high mortality has been monitored (see SUMON monitoring). Growth seems significant, but the adults' initial weight required a finer analysis. Juveniles had a larger growth than the previous years, and especially on the west coast. On the adult side, maturation was well advanced in June, but the September biometrics showed disparate filling rates between the different stations, and had us suppose that the spawning season was on. |

| Le réseau régional de suivi REMONOR s'appuyant sur les acquis du réseau national REMORA de l'Ifremer, évalue chaque année la mortalité, la croissance et la qualité sur deux classes d'âges d'huîtres creuses (« adultes » = 2 ans et « juvéniles » = 1 an), réparties entre différentes stations dans les principaux secteurs ostréicoles Bas-Normands. Ce réseau, mené en collaboration par le LERN (Laboratoire Environnement Ressources de Normandie) et le SMEL (Syndicat Mixte de L'Equipement du Littoral), intègre deux nouvelles stations en 2006 : Veules les Roses (VR01), dont le suivi, allégé l'an dernier, est aujourd'hui complet et Denneville (CO10) qui doit compléter les connaissances sur le nord de la Côte Ouest du Cotentin. Une station est à l'étude cette année... |

| The network named REMONOR (REseau MOllusqueNORmandie) aims to assess mortality, growth and tissue quality of the Pacific oyster, Crassostrea gigas, cultivated in Normandy over an annual cycle. This local network relies on the same material and methods as the national one named REMORA (REseau Mollusques Ressources Aquacoles). The study was carried out in 17 sites, which were distributed in the four basins where oyster rearing occurs in Normandy (West and East coast of Cotentin, Baie des Veys and Meuvaines). In 2003, a new site was added, which was located in the area of Ver-Sur-Mer (Calvados). The results obtained in 2003 showed a low annual mortality for adults (8%) as well as for juveniles (10%). Growth was also low for the two age classes of oyster... |
