Description:

Recently, interest has grown in using oyster-mediated denitri ﬁcation resulting from aquaculture and restoration as mechanisms for reactive nitrogen (N) removal. To date, short-term N removal through bioextraction has received the mostmanagement interest, but there is a growing body of research that has shown oysters can also mediate the long-term removal of Nthrough denitri ﬁcation (the microbial conversion of reactive N to relatively inert dinitrogen (N 2) gas). Oyster suspension feeding and ammonium release via waste and deposition of organic matter to the sediments can stimulate nitri ﬁcation−denitri ﬁcation near oyster reefs and aquaculture sites. Oysters also harbor a diverse microbial community in their tissue and shell promotingdenitri ﬁcation and thus enhanced N removal. Additionally, surface areas on oyster reefs provide a habitat for other ﬁlter-feeding macrofaunal communities that can further enhance denitri ﬁcation. Denitri ﬁcation is a complex biogeochemical process that can be diﬃcult to convey to stakeholders. These complexities have limited consideration and inclusion of oyster-mediated denitri ﬁcation
