The effects of oyster harvest on resident oyster reef communities and reef structure in coastal Louisiana proper

, 2022
Harvest of the eastern oyster (Crassostrea virginica) is a primary contributor to oyster reef habitat disturbance in the northern Gulf of Mexico. The impacts of oyster dredging on reef substrate and resident fauna have not been thoroughly examined on the

Integrated assessment of oyster reef ecosystem services: Macrofauna utilization of restored oyster reefs

, 2016
Within the Harris Creek Oyster Sanctuary in the Maryland portion of Chesapeake Bay, we evaluated relationships between basic oyster reef characteristics and the abundance and biomass of macrofauna. The eight sites selected for these studies included five

Oyster reef ecosystem services: Macrofauna utilization of restored oyster reefs - Harris Creek, Maryland, USA

, 2019
Oyster reefs provide habitat for a variety of macrofauna species. Our studies focused on the relationship between oyster tissue biomass density and reef-associated macrofauna biomass density.

Sustainable oyster shell incorporated artificial reef concrete for living shorelines

Construction and Building Materials
An innovative pervious concrete containing recycled oyster shells for artificial reef structures has been developed. The new artificial reef concrete incorporating oyster shells contained higher amounts of supplementary cementitious material and sea sand

The biogeography of trophic cascades on US oyster reefs

Ecology Letters, 2014
AbstractPredators can indirectly benefit prey populations by suppressing mid‐trophic level consumers, but often the strength and outcome of trophic cascades are uncertain. We manipulated oyster reef communities to test the generality of potential causal factors across a 1000‐km region.

Eastern Oyster Recruitment Patterns on and Near Natural Reefs: Implications for the Design of Oyster Reef Restoration Projects

Journal of Shellfish Research, 2020
The spatial relationship between adult eastern oyster Crassostrea virginica populations and recruitment to the benthos of their offspring is not well understood. It is well established that larvae can be widely dispersed, but the relationship between dispersal potential and actual recruitment patterns across the full range of spatial scales involved ...

Hyperspectral remote sensing of wild oyster reefs

Estuarine, Coastal and Shelf Science, 2016
The invasion of the wild oyster Crassostrea gigas along the western European Atlantic coast has generated changes in the structure and functioning of intertidal ecosystems. Considered as an invasive species and a trophic competitor of the cultivated conspecific oyster, it is now seen as a resource by oyster farmers following recurrent mass summer ...

Oyster reef enhancement utilizing gardened oysters in a subtropical estuary

Restoration Ecology, 2019
Crassostrea virginica, the eastern oyster, is a native foundational species that inhabits coastal and estuarine ecosystems along the western Atlantic seaboard. Introduction of C. virginica into estuarine areas with limited or no extant populations is gaining popularity as a pro‐active approach for improving estuarine water quality and creating natural ...

How long does oyster shell last on an oyster reef?

Estuarine, Coastal and Shelf Science, 2006
Abstract A reduction in population abundance, brought on by an unprecedented 6 years of low recruitment, has reduced shell input through natural mortality on Delaware Bay oyster beds. Quantitative stock surveys provide an estimate of surficial shell over the same time period, permitting the reconstruction of the time history of shell since 1998 and ...

The global fall and rise of oyster reefs

Frontiers in Ecology and the Environment, 2020
Non‐native species that act as ecosystem engineers – creating new or reintroducing former habitats – challenge perceptions in conservation and restoration. In the wake of the loss of oyster reefs worldwide, non‐native Pacific oysters (Magallana gigas) are now spreading extensively across the former distributions of native reef‐building oyster species ...
