Use of encapsulated live microalgae to investigate pre-ingestive selection in the oyster Crassostrea gigas

  title={Use of encapsulated live microalgae to investigate pre-ingestive selection in the oyster Crassostrea gigas},
  author={Emmanuelle Pales Espinosa and Laurent Barill{\'e} and Bassem Allam},
The involvement of algal chemical cues in the pre-ingestive selection of food particles in Crassostrea gigas was studied using a new approach. Live cells of two microalgal species, Nitzschia closterium and Tetraselmis suesica, were separately entrapped in small alginate microcapsules using an emulsification/internal gelation method. Microcapsule size was adjusted to be within the range of particles ingested by oysters. Using this technique, about 80% of microcapsules had a diameter ranging from… CONTINUE READING
