Several pallets stacked with triangular, mesh-textured concrete artificial reef blocks sit under the shade of a large tree on a grassy riverbank. In the background, a calm river flows past a dense line of green mangroves on the opposite shore under a hazy sky

Today on Marine Science Minute with Florida Sea Grant: Oyster Restoration!

Two people wearing hats, sunglasses, and gloves work together on a muddy shoreline to position a long, textured grey concrete block onto a row of similar artificial reef modules. The block features a highly irregular, mesh-like surface pattern, with coastal houses, palm trees, and a white SUV visible in the background under a cloudy sky.

Oyster reefs are vital to estuaries, where freshwater meets saltwater. They provide habitat for small organisms, are feeding grounds for important fish species like snapper and grouper, and stabilize shorelines.

Oysters are also filter feeders. They remove nutrients from the water, which improves water quality. As ecosystem engineers, oysters are used in living shoreline restoration projects 

The Florida Sea Grant plastic-free restoration of oyster shorelines, or PROS, promotes the use of plastic-free materials in building restored oyster reefs.  

There are over fifteen PROS sites across Florida, reducing plastic in our waters, protecting shorelines from erosion, and providing structures for oysters to thrive on!
