In Florida’s Mosquito Lagoon, discarded oyster shells became the foundation for a restoration experiment designed to rebuild oyster reefs damaged by years of environmental pressure. As such, the waste is transformed into an important tool in marine restoration, allowing researchers to understand the importance of seemingly simple actions and the major ecological consequences they can have.
Researchers used mesh mats covered with recycled oyster shells to create a stable surface where young oysters could attach and form new reef structures.The technique involved using used oyster shells to build mats submerged in the water and placing them in the areas where there was a need for new oyster reefs. As per research done on the material for restoration of the oysters published in the NOAA repository, 36 recycled oyster shells were affixed to each mat covering 0.25 sq m, thereby forming a set surface for the settlement and growth of juvenile oysters. Over the following years, the restored areas developed into functioning oyster reefs as juvenile oysters settled and grew on the artificial structures.
