Optimizing Coral Cultivation Through Light–Feeding Interactions
This study demonstrates that coral growth and coloration are shaped by species-specific interactions between blue light intensity and heterotrophic feeding, highlighting the importance of tailoring environmental regimes in ex-situ culture systems. Using two common reef-building corals, Stylophora pistillata and Pocillopora damicornis, the study shows that high blue-light intensity combined with enhanced feeding can synergistically promote growth in S. pistillata, while P. damicornis exhibits a more conservative, light-tolerant strategy. Despite these contrasting responses, both species maintained high photosynthetic efficiency and survival, underscoring the physiological resilience of corals under controlled conditions. By clarifying how light and feeding jointly influence coral performance, this work provides practical guidance for optimizing high-density coral aquaculture. These insights are directly relevant to reef restoration initiatives and the sustainable production of corals for the ornamental trade.
