Les activités de production - conchyliculture ArchiMer
Deschamps, Gerard; Miossec, Dominique; Pannier, Thierry; Huet, Jerome; Lorance, Pascal.
These studies of halieutic ecology produced at the request of Electricité de France by the French Institute of Research for Exploitation of the Sea in the Normand Breton Gulf must constitute one of the elements making it possible to come to a conclusion or not on the feasibility of the tidal power plant construction project; these studies have three parts: The first part discusses halieutic zooplankton. In the first place, the main species that constitute the exploitable living resources are considered, observed from the first stages of their life, in the egg or at different larval stages preceding the juvenile state. Also of interest are certain holoplanktonic groups. The whole of these observations establishes the status of zooplanktonic populations...

Production de juvéniles de bar (Dicentrarchus labrax) en marais. Etude de trois séquences alimentaires de sevrage ArchiMer
Buchet, Vincent; Palvadeau, Hubert; Boussard, O..
Trials on the seabass weaning in atlantic marshes (Roux, 1993), have shown that the use of frozen prey improved this step and reduced his resulting stress. During the present study, which must confirmed these preliminary results, three alimentary sequences were tested. 1) natural zooplankton, weaning pellets, as control, 2) natural zooplankton, inert artemia (intensively produced), weaning pellets, 3) natural zooplankton, natural frozen zooplankton (harvested), weaning pellets. The achieved results show that weaning with intermediary phases (sequences 2 or 3) yield best results. Furthermore the phase with artemia yields, systematically, better results than with harvested zooplankton ; then artemia seems a excellent substitute food representing a...

Ecotron - Embiez 8 - Modélisation de la production d'organismes planctoniques dans les bassins ArchiMer
Nival, Paul; Malara, G..
Choosing the best conditions for the cultivation of plankton in tanks is a difficult deal, which is generally solved by means of subjective estimations. A better way of looking for these conditions is the use of a mathematical model. _ We have tried to built a model that accounts for the physical and bio­logical characteristics of the tanks. The data concerning the physiological characteristics of the different group of organisms encountered are too scarce to allow all of them to be taken into account. The system studied here is composed of nutrients, phytoplankton, herbivorous copepods and rotifers to which benthic algae have been added. With the hypothesis of 3 elements (phyto - zooplankton - nutrients) it can be showed that when an equilibrium is...

Variations of zooplankton in the frontal area of the Alboran sea (Mediterranean sea) in winter 1997 ArchiMer
Youssara, F; Gaudy, R.
Zooplankton from the upper 200 m of the Almeria-Oran frontal region, (east of the Alboran sea, western Mediterranean) was sampled during winter 1997, using two nets equipped with 200 and 80 mum mesh. Eight sites representative of the different hydrodynamic structures (Mediterranean water, geostrophic Atlantic jet, associated anticyclonic gyre) were investigated over 2 d, using two day- and two night-samples per site. Zooplankton biomass was correlated to chlorophyll abundance, with lowest values in the oligotrophic Mediterranean water and highest in Atlantic water. The high biomass resulted from the enhancement of the secondary production, as indicated by the greater proportion of nauplii and the increase of zooplankton metabolism and feeding. Total...

Time series analysis of interrupted long-term data set (1961-1991) of zooplankton abundance in Gulf of Maine (northern Atlantic, USA) ArchiMer
Licandro, P; Conversi, A; Ibanez, F; Jossi, J.
The main interannual and seasonal signals have been extracted from a multi-decadal data set of zooplankton collected with the Continuous Plankton Recorder in the Gulf of Maine, from January 1961 to December 1991. The monthly abundances of seven species or genera of copepods representing the dominant biomass in the area were considered. The presence of a large consecutive gap (35 months) prevented the use of statistical methods for the prediction of missing data. The eigen-vector filtering (EVF) method was then used on the original time series, while retaining the missing values. For each zooplankton taxon, two principal modes of variability (F-1 and F-2) were extracted, representing the interannual and seasonal variations, respectively. Results of EVF...

Environmental control of mesozooplankton community structure in the Seine estuary (English Channel) ArchiMer
Mouny, P; Dauvin, Jc.
This paper is the first to describe the spatio-temporal changes of mesozooplankton in the Seine estuary. Monthly samples were collected along the estuary in 1996 in order to analyse the seasonal changes of the mesozooplankton community and to identify the major environmental parameters that may influence the spatial distribution of zooplankton in this megatidal estuary. Statistical analysis (canonical correspondence analysis) showed that salinity was the main factor correlated with the longitudinal distribution of zooplankton. Marine species (Temora longicornis, barnacle larvae...) were located in the outer part of the estuary, while more oligohaline species (Eurytemora affinis) were recorded in the inner part of the estuary. A mixed zone was characterised...

Marine zooplanktonic diversity: a view from the South Atlantic ArchiMer
Boltovskoy, D; Correa, N; Boltovskoy, A.
Approximately 7000 marine zooplanktonic species have been described so far for the World Ocean; in the South Atlantic the presence of 40% of these has been confirmed, and an additional 20-30% are expected to be recorded in the future. The overall number of described species is very low when compared with other communities, and yet it may not be too far from the final, complete inventory. Very ample geographic distributional ranges, compositional similarity between the major oceanic basins, and declining species description rates suggest that the undescribed fraction of marine zooplankton is nowhere as large as those suggested for the biosphere as a whole. It is anticipated that the highest proportions of new species will be among the groups associated....

Etude de la dynamique des populations zooplanctoniques au sein d'une claire ostréicole ArchiMer
Sajus, Marie-celine.
Marteilia refringens est un protozoaire parasite de l'huître plate Ostrea edulis, à l'origine de mortalités dramatiques en élevage depuis les années 1970. En zone endémique, le seul moyen de contrôle de la marteiliose, est une gestion du risque de contamination. Dans ce cadre, la connaissance du cycle parasitaire de Marteilia refringens est primordiale. Les travaux réalisés à ce sujet ont permis de poser l'hypothèse d'un cycle hétéroxène. Le parasite a été détecté par PCR puis localisé au sein des tissus par hybridation in situ au sein d'une espèce de copépode Calanoide prélevée dans une claire ostréicole. A ce stade, cette espèces peut être considéré comme un hôte de Marteilia refringens. Notre étude consistait à mettre en évidence la dynamique des...

Approche systémique des potentialités de production secondaire pélagique: inférences de fluctuations interannuelles ArchiMer
Bergeron, Jean-pierre.
Une méthode d'estimation des potentialités de production secondaire pélagique est proposée, tirant profit de l'homologie interspécifique de certains processus métaboliques élémentaires. Elle consiste à mesurer l'activité de l'aspartate transcarbamylase (A TC), enzyme contribuant à la biosynthèse de composants de base des acides nucléiques, sur des échantillons du peuplement mésozooplanctonique total. L'exécution de onze campagnes au cours des périodes printanières de trois. années consécutives, de 1978 à 1980, a permis d'appliquer cette approche à un écosystème néritique de région tempérée, situé au large de la côte nord de la Bretagne (Manche occidentale). Les onze séries de données ainsi acquises prêtent à caractériser les traits essentiels de...
