French Research Institute for the Exploitation of the Sea

The French Research Institute for the Exploitation of the Sea, is an industrial and commercial public company. The Invertebrates Physiology Laboratory (LPI) of IFREMER is located in Brest and is internationally recognized for its work in reproduction, growth, nutrition, larval development and metamorphosis of marine bivalves. The LPI is divided in two complementary groups. One is located in Brest and dedicated to analytical aspects of mollusc physiology (biochemistry, enzymology, microbiology and molecular biology including transcriptomics and functional genomics). The other is located in Argenton at the western extremity of Brittany and is dedicated to laboratory experiments on the ecophysiology of all life cycle stages of molluscs (larvae, seed and adults). This large experimental facility (700m2) allows precise experimental work to be done on broodstock management, larval and post-larval rearing.

Tasks attributed

IFREMER (LPI/PFOM) plays a major role in the project both as coordinator and dissemination (WP1) and by participating actively in WP3 and WP5 on recirculating systems for oyster larvae and seed, genetic diversity of oyster seed (LGP La Tremblade), control of bacterial communities and phytoplankton production improvement. The institute also contributes to WP2 on oocyte maturation and gamete quality.

Key persons

Jean-Louis Nicolas 
A senior researcher in marine microbiology at IFREMER. He (PhD, HDR) has worked on microbiology and pathology in marine molluscs since 1995 and in shrimp since 2005. Moreover, he has isolated and characterized numerous pathogens from diseased molluscs (herpes virus, Vibrio manilatis, V. pectenicida, V. harveyi, V. aestuarianus, V. coralliilyticus). He has recently undertaken a comparison of three vibriosis in mollusc including immune response and purification of virulent factors, a program on marine probiotics , notably the development of axenic microalgae associated with probiotics.

Pierre Boudry

Dr Boudry (PhD, HDR) has worked within IFREMER as a geneticist since 1995, focusing on marine bivalves. His research interests include quantitative genetics and breeding, polyploidy and cytogenetics, phylogeny and population genetics, gene expression and genomics. He has participated in numerous national and EU funded projects, e.g. GENEPHYS, BLUE SEED, and AQUAFIRST. Since 2009, he has been in charge of the group working on physiological regulations in molluscs.

René Robert

Dr Robert (PhD, HDR) joined the part of IFREMER formerly known as ISTPM in 1980. He has been the manager of the IFREMER Experimental Station at Argenton since 1995 and has worked on research aquaculture of clams, pectinids (scallops) and oysters since 1982. His areas of expertise include growth and reproduction of molluscs, ecotoxicological evaluation and the ecological and physiological requirements of larvae and seed - particularly focusing on their nutritional needs and diet improvement (phytoplankton production and alternative substitutes).

Other scientists involved:

Arnaud Huvet

Dr Huvet (PhD, HDR) is a specialist in genomic and functional physiology. He is studying on the regulation of genes involved in reproduction and energy status, which influence notably the resistance to stress and pathogens

Charlotte Corporeau

PhD; She is studying the quality of gametes through the biochemical analyses (lipids, enzymology, ...) and proteomic analysis (2D gels). She will be helped by Stéphanie Madec PhD (no permanent staff) who is a specialist of proteomic and bacterial physiology.

Marc Suquet

He is a specialist of gamete quality and cryopreservation. He is studying the gamete quality of oyster in function of method of obtention of gametes (spawning or stripping) and the localisation of gamete samples in gonads.
