New Seeding Approach Reduces Costs and Time to Outplant Sexually Propagated Corals for Reef Restoration.

The use of sexually propagated corals is gaining popularity as an approach for reef restoration. However, manually attaching substrates with recently settled corals to the reef using binding materials is both time-consuming and expensive, limiting the use of this technique to small spatial scales. We present a novel approach whereby young corals are 'seeded' on the reef without the need for manual attachment to the benthos.
