In 2021, researchers began placing concrete-block oyster reefs in bare eelgrass patches on Prince Edward Island; within two years biomass was about 45 times higher and 45 taxa had colonised the structures

Innovative artificial oyster reefs have been created off Prince Edward Island to boost marine biodiversity and create habitats. In just two years, these structures attracted 45 different species, enhancing biomass significantly. They also offered vital surfaces for oyster growth, improving environmental conditions. The initiative, in collaboration with Lennox Island First Nation, highlights the ecological and cultural significance of restoring oyster populations and demonstrates new methods for revitalizing coastal ecosystems.
