| Mussel aquaculture is well developed in various ecosystems of temperate waters. In the aim of developing predictive tools for management of mussel aquaculture, a better understanding of relationships between the environmental conditions and mussel growth is necessary. For this purpose, development of bioenergetic models, linking environmental variables (especially food resource and temperature) and mussel growth and reproduction, are of a particular interest. Dynamic Energy Budget (DEB) theory offers a general framework to study energy flows in organisms, from assimilation to use for maintenance, growth and reproduction. This theory is appropriate for growth modelling of marine organisms and have first been applied in 1993 to model mussel growth.... |

| 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 conditions (trophic sources, temperature). This study aimed to develop a mechanistic model coupling the kinetics of PST accumulation and bioenergetics in C. gigas based on Dynamic Energy Budget (DEB) theory. For the first time, the Synthesizing Units (SU) concept was applied to formalize the feeding preference of oysters between non-toxic and toxic microalgae. Toxin intake and accumulation were both dependent on the... |
