What is microfragmentation in coral propagation?

Microfragmentation in coral propagation refers to a technique where small pieces, or fragments, of coral are created by cutting healthy coral colonies into smaller sections. This process significantly speeds up the healing and growth rates of corals compared to traditional methods of propagation, which typically involve larger pieces. The smaller fragments have a higher surface area to volume ratio, allowing for more efficient uptake of nutrients and a quicker recovery from trauma, leading to enhanced growth.

The method is particularly useful in coral restoration efforts as it allows for more corals to be propagated and transplanted to degraded reefs in a shorter period. By utilizing microfragmentation, restoration projects can increase the resilience of coral populations and aid in their recovery in the face of environmental stressors.

In contrast, selecting healthy colonies, assessing coral health, or identifying new coral species involve different techniques and processes that do not specifically relate to the propagation and accelerated growth facilitated by microfragmentation.
