Abstract
Maldivian coral reefs have undergone a substantial degradation due to a combination of anthropogenic pressure and global climate change. In response to the 2016 coral bleaching event, Anantara Dhigu, Anantara Veli, and Naladhu Private Island launched the Holistic Approach to Reef Protection (HARP) project, aiming to restore the house-reef. This study, a key component of HARP, evaluates the effectiveness of two coral nursery designs, rope-based and metal table-based, at two depths (⁓2 m and⁓5 m) for the propagation of Acropora aspera , Acropora muricata , and Montipora digitata . Over six months, bimonthly underwater surveys assessed growth rates, ecological volume, health conditions, disease presence, predation, and survival rates. Results indicate that rope-based nurseries generally outperform metal tables, with higher growth rates and better survival rates observed on ropes. Specifically, Montipora digitata showed the most substantial growth at 2 meters depth, reaching up to 5 cm in six months. Additionally, rope nurseries demonstrated significantly lower predation rates and better overall health conditions compared to metal tables. While coral survival was comparable across nursery designs, the study suggests that shallower depths favor coral growth due to enhanced light availability. However, shallower depths also correlated with higher mortality during a recent bleaching event, emphasizing the need to balance depth considerations with potential thermal stress. This study underscores the advantages of rope-based nurseries in promoting coral growth and survival, offering valuable insights for coral restoration strategies in shallow lagoon ecosystems.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
