Article
This study was designed to assess the contribution of feeding behavior to inter-individual variability of paralytic shellfish toxin (PST) accumulation in the Pacific oyster Crassostrea gigas. For this purpose 42 oysters were exposed for 2 days to non-toxic algae and then for 2 other days to the PST producer Alexandrium minutum. Individual clearance...
Article
As other filter-feeders, Crassostrea gigas can concentrate paralytic shellfish toxins (PST) by consuming dinoflagellate phytoplankton species like Alexandrium minutum. Intake of PST in oyster tissues mainly results from feeding processes, i.e. clearance rate, pre-ingestive sorting and ingestion that are directly influenced by environmental conditio...
Article
In this study, we assessed the Atlantic surfclam (Spisula solidissima) energy budget under different ocean acidi-fication conditions (OA). During 12 weeks, 126 individuals were maintained at three different ρCO 2 concentrations. Every two weeks, individuals were sampled for physiological measurements and scope for growth (SFG). In the high ρCO 2 tr...
Article
A dynamic energy budget (DEB) model integrating pCO2 was used to describe ocean acidification (OA) effects on Atlantic surfclam, Spisula solidissima, bioenergetics. Effects of elevated pCO2 on ingestion and somatic maintenance costs were simulated, validated, and adapted in the DEB model based upon growth and biological rates acquired during a 12-w...
Article
The king scallop, Pecten maximus is a highly valuable seafood in Europe. Over the last few years, its culture has been threatened by toxic microalgae during harmful algal blooms, inducing public health concerns. Indeed, phycotoxins accumulated in bivalves can be harmful for human, especially paralytic shellfish toxins (PST) synthesized by the micro...

The oyster Crassostrea gigas is one of the most commercialized molluscs in the world. It is a very cosmopolitan species that has been disseminated by humans and is susceptible to various agents such as pathogens (bacteria, viruses), parasites, xenobiotics and/or toxic micro-algae. As a filter-feeder, it may accumulate phycotoxins while feeding on h...
Thesis
Full-text available
L’huître creuse Crassostrea gigas est l’un des mollusques les plus commercialisé au monde. Cette espèce cosmopolite doit faire face à de nombreux agents pathogènes (bactéries, virus), parasites, xénobiotiques, et/ou micro-algues toxiques. En tant que bivalve filtreur, elle peut accumuler de fortes charges de phycotoxines, dont les toxines paralysan...
