| L’étude de zone des lotissements conchylicoles de la lagune de Thau (34.39) a été menée, à la demande du Comité Régional de la Conchyliculture en Méditerranée et du préfet de l’Hérault, pour étudier la possibilité de sectoriser la zone de production en sous-zones, au regard du risque microbiologiques (REMI). Une étude de dossier a été réalisée afin de recenser les principales sources de contamination. Celles-ci sont essentiellement d’origine anthropique et impactent différemment les secteurs envisagés. Des prélèvements de coquillages du groupe 3 ont été réalisés de mai 2017 à mai 2018 avec une fréquence bimensuelle. Au regard des critères du règlement (CE) n° 854/2004, les résultats des analyses microbiologiques (indicateur Escherichia coli) ont permis... |

| The monitoring network IFREMER/REMORA in Thau lagoon is assessing, on a yearly basis, mortality, growth and quality criteria distributed among 6 stations. Samplings are carried out in March, June, September and December. 2003 is a year with a very important mortality in Mèze and Marseillan area due to an anoxy and an anormal mortality at Bouzigues Nord in december. The growth rate is always better than others French oysters areas. Afnor index is high (beetwen 13.7 and 16.5 in december), so the totality of the oysters are classifed in "Spéciales". Polydora sp. Index is important but the initial stock was first infected. The valve quality is good, with no gelatine, except on Bouzigues South. |

| This report presents the main results for 2002 of the eight points in the Lagune de Thau, in accordance with the monitoring network REMORA: 3 national points and 5 regional added by the «Laboratoire Conchylicole de Méditerranée». Only adults batch is observed in the Mediterranean sea. This year the mortality ratio is low (< 5 %), without significant differences between areas. Like for the whole national network, the average individual weight are less than previous years in Bouzigues and Marseillan area ; in opposite Mèze area has better results. Bouzigues area presents the best productivity rate (3.1) and the worst in the middle of the zone. The AFNOR index, calculed in December, allows to classify the oysters like "spéciales". The best values are... |
