Croissance et qualité de l'huître ceuse Crassostrea gigas dans le bassin de Thau (Hérault) : Résultats d'une étude réalisée en 1990-1991 ArchiMer
Pichot, Paul; Landrein, Sonia; Juge, Claude.
During years 1990-1991, a study was carried ouI in order to precise the relationship between sorne physiological features and the biochemical characteristics of dry flesh and hemolymf of oyster Crassostrea gigas, cultivated in the mediterranean lagoon of Thau. Growth rates and biochemical analysis for proteins, lipids and carbohydrates were estimated. The results of this study are given. They include many other data from a study on trophic relationships developed between 1985-1989.

Effect of sediment nearness on the metabolic enzyme activity and energy state of the oyster Crassostrea gigas ArchiMer
Le Moullac, Gilles; Fleury, Pierre-gildas; Le Coz, Jean-rene; Moal, Jeanne; Samain, Jean-francois.
This study was designed to assess in situ the effects of sediment nearness on Crassostrea gigas metabolism. One year-old oysters were reared for 5 months (April-August) in plastic bags on metallic frames at 10 and 60 cm off the sediment at the beginning of April. The management of the energetic resources (storage, consumption) was estimated with respect to biochemical changes of proteins, lipids and carbohydrates. In order to evaluate the effect of the sediment nearness at cellular level, the metabolic rate was evaluated by assessing pyruvate kinase (PK) and phosphoenolpyruvate carboxykinase (PEPCK) enzyme activities and electron transport system (ETS) activity. The metabolic pathways were assessed by measuring ATP and intermediary metabolites such as...

Matière en suspension et sédimentation dans la lagune de Thau ArchiMer
Pichot, Paul; Deslous-paoli, Jean-marc; Juge, Claude.
Thau is a mediterranean lagoon with a large productive stock of molluscs (oysters, mussels) cultivated on suspended tines and colonised by epibionta (ascidia and others invertebrates, algae, etc ... ). This study was developed as part of the PNOC-OXYTHAU.programme. Its aim was to analyze the effects of oyster farrning on water-mass surrounding structures loaded with suspended molluscs and proximal watermass separating these structures. This study concems particulate suspended matter and deposits of particulate organic matter on the bottom after sedimnentation. Biochemical measurements were carried out for nitrogen, carbon,  proteins, lipids and carbohydrates. ln order to estimate sedimentaton, bottom sediment traps were used

Ontogeny of the gastrointestinal tract of marine fish larvae ArchiMer
Zambonino, Jose-luis; Cahu, Chantal.
Marine fish larvae undergo major morphological and cellular changes during the first month of life. The ontogeny of the gastrointestinal tract combines these two aspects of the larval development and is very interesting in that the timing of functional changes appears genetically hard-wired. The goal of this paper is to give an overview of the gastrointestinal development process in marine fish larvae, with particular attention to three species: sea bass; red drum; and sole, since the description of gut maturation in fish larvae was initiated during the last decade with these species. During the early stages, marine fish larvae exhibit particular digestive features. Concerning the exocrine pancreas, amylase expression decreases with age from the third week...
