Novel, human-made structures for coral settlement (new shapes, sizes and surfaces) can enhance reef structural complexity and provide surfaces to promote coral resettlement and growth. They can range from micro-scale engineering to artificial reefs.
Placing large, manufactured structures such as BioballsTM or Subcon Mushrooms onto degraded reefs could facilitate coral resettlement, improve survival rates, enhance herbivory, fish diversity and growth of immobile organisms.
They would be deployed from large barges.
