. Résumé, Un manque de croissance a été identifié dans une ferme de Ruditapes philippinarum en, 2011.

. Croissance, d'ingestion (IR) et d'assimilation (AE) ont été mesurés en 2012, ainsi que des paramètres environnementaux comme la température et la concentration algal, afin d'identifier les raisons de ce

C. Les, ml.h -1 .gPS -1 et de 0.017 à 0.002 gPS d'algue.h -1 .gPS -1 , de 8 à 28mm Ces de taux ont chuté quand la concentration algale est passée en dessous de 20 000 particules.ml -1 , qui est probablement la concentration algale limitante mentionnée auparavant dans la littérature. AE n'est pas affectée par les facteurs environnementaux, mais a été relevée plus faible pour de faibles IR et CR standardisés, ce qui élude la théorie d'un IR saturé pour expliquer les faibles AE, model développé a montré qu'une élévation de la concentration algale à de faibles concentrations algale est le meilleur moyen d'augmenter l'IR
