Oyster reefs can host over 300 species of marine life.

Oyster reefs support 2–5x more biomass.

Oyster reefs are biodiversity hotspots. By creating complex, three-dimensional habitat, oysters provide shelter, breeding grounds and feeding areas for a wide range of marine organisms. From microscopic invertebrates to commercially important fish, these reefs offer critical refuge in coastal environments under pressure from pollution, overfishing and habitat degradation. Their ecological value rivals that of coral reefs and seagrass beds.

Unlike bare mudflats or sandy bottoms, oyster reefs form rugged structures with crevices and layers - ideal conditions for marine life to thrive. Reefs create vertical relief that supports hundreds of associated species.

How it works:

• Shelter & Refuge: Oyster reefs structures offer protection from predators and strong currents.

• Nursery Habitat: Juvenile fish and invertebrates use reefs as safe rearing grounds.

• Food Web Support: Oysters enhance primary and secondary productivity, forming the base of a rich trophic system.

• Species Aggregation: Reefs attract mobile species like fish, rays and cephalopods, increasing local abundance and diversity.

• Habitat Connectivity: Oyster reefs link nearby ecosystems such as mangroves, seagrasses, and mudflats, supporting coastal resilience.
