Approche quantitative de la fonction de nourricerie jouée par les systèmes vasières-estuaires ArchiMer
Parlier, Emmanuel.
Coastal fish populations settle more or less frequently, at various stages, estuarine systems. Tidal marshes are one of the components of these mosaics of habitats. The first part of this work describes fish assemblages through the utilisation of these systems by fishes analysed in order to propose a revised functional classification of ecological guilds. T h i s new classification is used to compare fish communities of four estuarine systems in the western coast of France: the Mont Saint- Michel Bay, the Saint-Brieuc Bay, the Loire estuary and the Aiguillon Bay. The second part aims at characterizing the nursery function as defined by Beck et al. (2001). Acombinative approach based on gut content analysis, and stable isotope analysis shows that Yo Y s e a...

Etude des nourriceries de la Baie de Seine orientale et de l'estuaire de la Seine ArchiMer
Morin, Jocelyne; Riou, Philippe; Bessineton, Christophe; Vedieu, Christophe; Lemoine, Michel; Simon, Serge; Le Pape, Olivier.
This study, carried out from 1995 to 1997, within the framework of "Le Havre" harbour extension project, concerned halieutic populations and the characterization of a coastal nursery in the oriental part of the Seine bay and the Seine estuary . The main objective was to describe the specific and demographic composition of marine populations and their spatio-temporal distribution, and so assess the biological and halieutic role of this area. This study also included a research about the dietary needs of fish juveniles living in the estuary. Autumn and winter surveys results show that the estuary and area under direct influence are the richest from a biological and halieutic point of view. The mouth estuary isthe richest area in terms of diversity of...

Mise au point d'une stratégie de prégrossissement intensif en nourricerie de palourdes (R. philippinarum) et d'huîtres (c. gigas) dans la région de la baie de Bourgneuf ArchiMer
Baud, Jean-pierre.
Japanese clam and hollow oyster spats have been pre-grown under intensive conditions in hatcheries using underground seawater as thermal resource and as source of nutritional salts for forage seaweed production. The main parameters of this environment have been followed up and raising conditions have been controlled (spat density, seawater flow, phytoplankton concentration and temperature). The biological results obtained after interaction processing and the hierarchy of the studied parameters were the object of an economic analysis for each season, comparing different shellfish pre-growth strategies. This study finally allows us to be able to present pre-growth intensive methodology that can be passed on to the professional aquaculture industry.

Rapport de la campagne SOLPER 1 (26 août – 2 septembre 2005) ArchiMer
Leaute, Jean-pierre.
To estimate the size and abundance distribution of juvenile sole (Solea solea) of nurseries in the Pertuis charentais (France) in 2005, a small beam trawl of 2 m wide and 8 mm stretched mesh was used over a hundred sampling points. The other fish catches have also been recorded.

Rapport de la campagne SOLPER 2 (28 août – 2 septembre 2006) ArchiMer
Leaute, Jean-pierre.
To estimate the size, age and abundance distribution of juvenile sole (Solea solea) of nurseries in the Pertuis charentais (France) in 2006, a small beam trawl of 2 m wide and 8 mm stretched mesh was used over a hundred sampling points. The other fish catches have also been recorded and water temperatures measured.

Relative contributions of different sole and plaice nurseries to the adult population in the Eastern Channel: application of a combined method using generalized linear models and a geographic information system ArchiMer
Riou, Philippe; Le Pape, Olivier; Rogers, Stuart I..
The Eastern Channel (ICES division 7d) is considered a unit for stock management of the common sole Solea solea and the plaice Pleuronectes platessa. At this scale, the aim of this work is to model the juvenile distribution of these flatfish. The database used, based on different surveys undertaken during the two last decades, includes 4500 coastal beam trawl hauls throughout the Eastern Channel coasts. Multivariate analyses are used to study the interannual fluctuations in flatfish recruitment of the region. This approach allows us to separate the Eastern Channel into homogeneous sectors with regard to these fluctuations. The physical parameters that contribute to the observed juvenile sole and plaice distributions are identified and their distributions...

Stratégie de prégrossissement intensif de naissains de palourdes (R. philippinarum) et d'huîtres (C. gigas) en baie de Bourgneuf ArchiMer
Baud, Jean-pierre.
Du naissain de palourde japonaise et d'huître creuse a été prégrossi en conditions intensives de nourricerie au moyen d'une eau salée souterraine, utilisée comme ressource thermique et comme source de sels nutritifs pour la production d'algue fourrage. Les paramètres essentiels du milieu ont été suivis et les conditions d'élevage ont été contrôlées (densité de naissain, débit d'eau de mer, concentration de phytoplancton et température). Les résultats biologiques obtenus après traitement des interactions et de la hiérarchie des paramètres étudiés ont fait l'objet d'une analyse économique, pour chaque saison, par rapport à différentes stratégies de prégrossissement des coquillages. Cette étude permet finalement de proposer une méthodologie intensive de...

Utilisation d'eaux salées souterraines en baie de Bourgneuf, pour le prégrossissement intensif de mollusques filtreurs en nourricerie ArchiMer
Baud, Jean-pierre.
L'utilisation d'une eau salée souterraine riche en sels nutritifs et de température constante a permis d'étudier l'influence des paramètres physicochimiques essentiels sur la croissance intensive de naissains de Crassostrea gigas et de Ruditapes philippinarum en nourricerie durant les périodes hivernales et estivales. Après la mise au point d'un procédé fiable de culture d'une algue fourrage, la variabilité saisonnière des composés biochimiques de la diatomée Skeletonema costatum produite en grands volumes extérieurs (50 m3) est étudiée. Les conditions d'élevage lors des différentes expériences sont contrôlées (densité de naissain, débit d'eau de mer, concentration de phytoplancton et température). Les différents résultats biologiques obtenus sont analysés...
