Research on Coral Cultivation and Base Stone Material

Abstract

Due to climate and environmental changes, the coral reef ecosystem has undergone severe degradation, leading to widespread bleaching, coral death, and a significant decline in live coral coverage. As a result, coral cultivation has become an urgent task, and the establishment of horticultural nurseries and the implementation of sexual reproduction for coral transplantation have emerged as crucial methods to address the scarcity of coral sources for transplantation. However, the selection of suitable attachment stones remains a challenge, as it significantly impacts the survival rates of transplanted corals. It is essential to choose appropriate base stones that not only align with the restoration of the original environment but also offer economic viability. The South China Sea coastline is abundant in sandstone, which possesses dense structure, large blocks, high porosity, and excellent water absorption characteristics, making it an ideal choice as a base stone for coral cultivation. Furthermore, these base stones can be shaped into familiar story scenes or characters, allowing for the creation of underwater coral gardens that serve as both a means of sustainable funding and a platform for scientific popularization and aesthetic education.By integrating these elements, a coral restoration and cultivation system can be developed, promoting a sustainable model that combines science education, aesthetic appreciation, and self-sustaining financial resources. This holistic approach not only addresses the pressing need for coral cultivation but also contributes to the preservation and revitalization of coral reef ecosystems.
