| A simple system was used to simulate the effect of alternating toxic (paralytic shellfish poisoning toxins) and non-toxic microalgal diets on oyster feeding behaviors and rates of toxin accumulation. These experimental conditions were meant to reflect, to some extent, the incoming and outgoing fluxes of toxic algae observed at the mouth of the Penze estuary (Northern Brittany, France). Physiological and toxicological parameters were estimated based oil fluorescence measurements recorded continuously at the outlet of each experimental tank, which contained a single oyster. Q(tox), this variable describes toxin uptake in oysters, it was used (instead of the toxin ingestion rate): i) in simple graphical analyses, ii) as well as in one- and two-compartment... |

| L'objectif de l'étude est de simuler les épisodes de contamination des huîtres par les toxines d'Alexandrium minufum à partir d'un module expérimental adapté, et en vue de construire un modèle de contamination applicable à cette espèce. Ce modèle sera ensuite susceptible d'être couplé au modèle biologique local (estuaire de Penzé) de déterminisme des blooms, ainsi qu'aux modèles hydrodynamiques développés par différentes équipes (Ifremer). |
