Modelling paralytic shellfish toxins (PST) accumulation in Crassostrea gigas by using Dynamic Energy Budgets (DEB)

Abstract: 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 D… Show more

“…Algal consumption was significantly higher for oysters exposed to A. minutum than for control oysters over the whole experiment. Pousse et al (2018) applied a mechanistic model based on Dynamic Energy Budget theory to the data of the present study, coupling the kinetics of PST accumulation and bioenergetics in C. gigas. They evidenced that toxicant stress provoked by A. minutum affected the energy balance of oysters, more energy being needed for tissue damage repair and detoxification of toxic substances produced by A. minutum.…”

“…Recently, a DEB (Dynamic Energy Budgets) model was developed for PSP toxins in the Pacific oyster [ 188 ]. Models of this kind include the main metabolic processes of bivalves (including spawning) and would be especially useful when long-term simulations are needed.…”

“…The immuno-suppressive effects on hemocytes from the eastern oyster Crassostrea virginica [54], or the production of reactive oxygen species by M. gigas gametes [227] exposed to the supernatant of this A. minutum strain might retrospectively be attributed to lytic compounds. A modelling approach (Dynamic Energy Budget modelling [228]), using the AM89BM strain, also revealed putative effects of A. minutum BECs on the physiology of oysters. Knowledge of the production of lytic compounds by this strain [67,68], enabled the authors to better constrain their model when they considered the production of BECs.…”
