Which structure is anchored to the seafloor as part of coral nursery systems?

The structure that is anchored to the seafloor as part of coral nursery systems is the A-Frame. A-Frames are designed specifically to support coral growth in a controlled environment while being firmly secured to the substrate. This anchoring to the seafloor is critical because it provides stability and a fixed position in the nursery system, allowing for optimal conditions for coral growth and development.

A-Frames are typically used to create a habitat that mimics natural conditions, enhancing the health and survival of corals while they mature before being transplanted to restoration sites. The design enables the corals to receive adequate light and flow of water, supporting their overall health.

In contrast, other structures like floating tables are not anchored and can rise and fall with the tide, making them less suitable for long-term coral nursery applications. Coral trees and coral frames, while they can support coral growth, are not specifically designed to be anchored structures in the same way A-Frames are. Their stability in the nursery system significantly enhances the efficiency of coral restoration efforts.
