1. Introduction: network organisation in 1997. The REMORA network - REseau MOIIusques du département Ressources Aquacoles de l'Ifremer - (Ifremer's Aquaculture Resources Department Mollusc Network) has been evaluating, since 1993, hollow oysters' growth (Crassostrea gigas) in major French oyster beds. In order to do so, it has followed up on a yearly basis the growth of a unique oyster batch shared among different stations in the main French raising areas. Releasing takes place in February and picking happens in November or December; intermediary sampling is done in June and September. All operations happen on the same dates for all stations. A national report is published each year. 'Regional' stations are sometimes added to the national network, but they...

The monitoring network IFREMER /REMORA is assessing, on a yearly basis, mortality, growth and quality criteria of two oyster batches ("juveniles" = one-year old ; and "adults" = two-years old), distributed among various stations of the main French oyster areas. Samplings are carried out in March, June, September and December. This network is a tool for trend estimations (geographic and chronological, on the national scale) ; it must not be considered as an accurate estimation of professional oyster ongrowings. In 2001, mortality mainly occured in Summer on "adults" in baie des Veys (Normandy) and on juveniles in Cancale and Pénerf (Brittany) and in Fouras and Marennes (Poitou-Charentes). With an average individual weigh of 59 g in December, 2001 has been a...

La crise anoxique du bassin de Thau de l'été 1997. Bilan du phénomène et perspectives
Provedor de dados: 5
Autores: Souchu, Philippe; Abadie, Eric; Vercelli, Catherine; Buestel, Dominique; Sauvagnargues, Jean-claude.
La crise anoxique ou «malaïgue» qui a sévi dans le bassin de Thau durant l'été 1997 a détruit presque le tiers de la production annuelle d'huîtres. Son déclenchement a suivi une période durant laquelle les vents étaient exceptionnellement faibles. Après un rappel scientifique des processus mis en jeu, la crise anoxique est décrite au travers des observations de mortalités et des concentrations en oxygène dissous. Les eaux anoxiques se sont développées dans les zones conchylicoles vers l'Est et l'Ouest à partir d'un foyer situé à proximité du principal port conchylicole (Mourre-Blanc à Mèze). La comparaison de la crise de 1997 avec celles qui l'ont précédée fait apparaître un recul de l'eutrophisation depuis 25 ans. En revanche, des secteurs très localisés...

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 (&lt; 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...

The monitoring network IFREMER /REMORA is assessing, on a yearly basis, mortality, growth and quality criteria of two oyster batches ("juveniles" = one-year old ; and "adults" = two-years old), distributed among various stations of the main French oyster areas. Samplings are carried out in March, June, September and December. This network is a tool for trend estimations (geographic and chronological, on the national scale) ; it must not be considered as an accurate estimation of professional oyster ongrowings. With the exception of Spring mortalities due to poor initial quality of adult oysters and to difficulties in the counting of juveniles, the year 2000 appeared to be a year of low mortality. 2000 is a year of poor growth (61.5 g in average weight in...

The Thau Lagoon, from time to time is the area of crisis locally called « malaïgues ». The characteristics of these « malaïgues » are the lack of oxygen interesting all the water column and the white color of the waters during the phenomena. The result of this anoxy is the death of cultivated molluscs. From 1969 to 2000 nine « malaïgues » have been observed. They occur during the Summer period but in different locations. The surface of the areas concerned are very different according the year. Different means of struggle have been tried and are described.

The Aquaculture Resources Department's mollusc network (REMORA) federates six coastal Ifremer laboratories. Since 1993, REMORA has implemented a unique national protocol to account for the variability in the growth of Pacific oysters farmed in 39 sites within the main production areas, from Normandy to the Mediterranean Sea. In 1995, the goal of the network was expanded to include monitoring of a second age class. To do so, the protocol developed for adults was adapted to monitor juveniles. The data, organised in Excel worksheets with a specific application written in Visual Basic, allows for inter-station and inter-annual comparisons and thereby constitutes a database of interest to oyster farmers, scientists and administrative personnel.

The feasability of the flat oyster Ostrea edulis culture development in the Languedoc-Roussillon Region has been studied at the Ifremer Station of Palavas, and aimed to diversify the cultured species and techniques commonly used in this region. Natural spat collection and the remote-setting technique were assessed as possible spat supply sources. The further steps of the cultivation cycle were carried out either on off-shore bottom culture facilities for nursery.

La densité d'élevage des mollusques est un des facteurs importants qui conditionnent la qualité de la production. Dans le bassin de Thau, une réflexion est actuellement en cours pour mettre en place un schéma des structures encadrant les pratiques conchylicoles de manière à améliorer et régulariser la qualité des huîtres. L'objectif de ce travail est de proposer, sur la base de données les plus objectives possibles, des recommandations en terme de densité d'élevage qui permettraient d'éviter une surcharge aussi bien locale que globale sur le bassin. Une première étude a consisté à réaliser une expérience, à l'échelle d'une table d'élevage, pour tester l'influence de la densité de population sur la croissance et la qualité de l'huître creuse (Crassostrea...

The network REMORA by IFREMER quarterly follows each year 2 batches of Pacific cupped oysters Crassostrea gigas ("juveniles"= 1 year old; and "adults" = 2 years old) on various sites among the main French oyster areas. The network monitored 46 sites in 2004, including the 7 new sites added in 2003. The network REMORA thus assess seasonal survival, growth and quality of cupped oysters. It is a tool for trend estimations, ecosystem management and a reference frame for scientific studies. Globally speaking, the year 2004 was a good year for oyster farming, with a low mortality and a fast growth. The rearing yield (survival x growth) reached 2.0 for adults instead of 1.8 usually. However, the meat index remained close to the average inter annual data....

Synthèse des travaux antérieurs : Depuis 1970, l’I.S.T.P.M. puis l'IFREMER (Equipe Diversification Conchylicole en Mer Ouverte, puis Laboratoire Conchylicole de Méditerranée) ont effectué de nombreux travaux pour tenter de développer la culture locale de l'huître plate. La problématique de cette filière d'élevage, pour laquelle existe une demande importante, se situe à deux niveaux : l'approvisionnement en naissain et la mortalité durant l'élevage dans l'étang de Thau. Pendant la période 1982-1991 : les études ont porté essentiellement sur l'approvisionnement en naissain, avec l'évaluation du potentiel offert par le captage naturel. Une attention particulière a été également portée à la définition des structures et des supports les mieux adaptés aux...

Depuis 1991, différents aspects de l'élevage de l'huître plate Ostrea edulis ont été étudiés dans le cadre des programmes de Diversification Conchylicole de la Station IFREMER de Palavas. Après avoir abordé successivement le potentiel du captage naturel, la technique du télécaptage, la mise au point d'un parcours d'élevage mixte mer-étang et le cycle de reproduction de cette espèce dans le milieu naturel, les travaux ont porté, en 1994, sur le contrôle de la maturation en captivité et la maîtrise du calendrier des émissions larvaires. Les mêmes expérimentations, répétées en 1995, ont été complétées par des essais portant sur la compression du cycle de reproduction.

Autores: Brehmer, Patrice; Vercelli, Catherine; Gerlotto, Francois; Sanguinede, Fabien; Pichot, Yves; Guennegan, Yvon; Buestel, Dominique.
The exploitation of offshore mussel farms is becoming important throughout the world, but monitoring this activity remains a difficult task. Here, we propose a specific method for this purpose. A total of 140 long-lines were monitored on a mussel culture ground in the French Mediterranean Sea during four experimental surveys deploying multibeam sonar devices mounted on poles (Reson Seabat 6012, 455 kHz) on small boats. This allowed geo-referenced observations to be made of the submerged mussel long-lines, as well as three-dimensional (3D) drawings of the long-line structures and the sea bed shapes, using long-line longitudinal sonar sampling. Three sonar data-analysis methods were applied: (i) direct two-dimensional (2D) visual interpretation of raw sonar...

We grew Pacific oysters (Crassostrea gigas) in a French Mediterranean coastal breeding area, the Thau lagoon, to examine the influence of stocking density on their growth and quality (i.e. condition index and biochemical composition). Oysters were reared on ropes suspended on a culture table for 15 months between March 1999 to June 2000 at 8 different densities involving two cross factors: the number of ropes per square (NR, i.e. 30, 50,65 and 100 ropes) and the number of oysters per rope (NO, i.e. 78 and 120 oysters). Environmental variables (temperature, salinity, dissolved O2) and trophic conditions (chlorophyll a, suspended particulate matter) were estimated fortnightly to characterise conditions prevailing inside as well as around the experimental...

In the first volume dystrophie crisis in the Thau lagoon since 1969 are described. In the second volume, meteorological parameters (temperature, wind, atmospheric pressure) are compared during the dystrophie crisis to show if either one or several parameters could explain the emergence of these phenomena . It seems that only a mathematical model could be able to give explanation.

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.
