Voeg label toe | Samenvatting: | The contribution of bivalve mollusks to world aquaculture production has shown a constant increase, which has been of great importance and impact as a source of food with high nutritional value, foreign exchange and jobs, thus generating significant interest during the last decades, including research carried out on aspects related to their functional anatomy, ontology, physiology and mechanisms used for their feeding. There are multiple publications and research done on this subject, some of which are referenced in this review. The present work begins by presenting generalities about oysters anatomy and emphasizes aspects related to their strategies for capturing, selecting and ingesting suspended particles, focusing on oysters of the genus Crassostrea, but with structures and mechanisms related to other species of bivalves as well, with which it bears strong similarities. Detailed information on the ctenidial structure and its development is presented, as well as on the main chemical, physical, environmental and physiological factors involved in the treatment of captured food particles, and finally the mechanisms proposed for the production of pseudo-feces. |
